1. New equipment: improve efficiency and reduce energy consumptionNew high-speed paper machines and energy-saving equipment play a key role in the energy saving and consumption reduction process of papermaking technology. With its excellent performance, high-speed paper machines have opened up a new path for improving energy utilization efficiency. Compared with traditional paper machines, high-speed paper machines can significantly increase production speed through advanced mechanical design and power systems. In a unit of time, high-speed paper machines can produce more cardboard, which means that when producing the same amount of cardboard, the high-speed paper machine requires a shorter operating time, which directly reduces the energy consumption per unit product. For example, in some modern paper mills, the operating speed of high-speed paper machines has increased several times compared with traditional paper machines, but energy consumption has dropped significantly, achieving a double improvement in production efficiency and energy saving effects.Advanced energy-saving equipment also plays an important role. In the operation of the papermaking process, the energy loss of equipment is an important part of energy consumption. Energy-saving equipment optimizes the transmission and utilization of energy by adopting efficient transmission systems and energy-saving motors. The efficient transmission system can reduce the loss of energy during the transmission process and ensure that more energy can be effectively converted into the operating power of the equipment. Energy-saving motors, with their higher power conversion efficiency, consume less electricity while providing the same power output. During the operation of the paper machine, traditional motors may need to consume a lot of electricity to drive the equipment, while energy-saving motors can significantly reduce electricity consumption while ensuring the normal operation of the equipment, reducing energy waste. 2. Precision control: ensure quality and reduce wastePrecisely controlling the flow rate, flow rate and running speed of the pulp is an important means for modern papermaking technology to achieve energy saving and consumption reduction. With the help of advanced automatic control systems, the papermaking process can accurately adjust various parameters according to the different specifications and quality requirements of the paperboard. When producing wood pulp coated kraft paper of different thicknesses and strengths, the automatic control system can quickly and accurately adjust the flow rate and flow rate of the pulp to perfectly match the running speed of the net, ensuring that the wood pulp fibers are evenly distributed on the net. This precise control not only ensures the stability of the quality of the paperboard, avoids the production of defective products due to quality problems, but also improves production efficiency.In the traditional papermaking process, due to the lack of precise parameter control, the pulp flow rate is often unstable and the flow rate is uneven, which easily leads to uneven distribution of wood pulp fibers, and the produced paperboard has quality problems such as uneven thickness and uneven strength. These defective products not only fail to meet market demand, but also cause double waste of raw materials and energy. The modern papermaking process effectively reduces the defective rate through precise control, so that every raw material and energy can be fully utilized, thus achieving the goal of energy saving and consumption reduction. 3. Intelligent system: real-time monitoring, dynamic adjustmentThe intelligent control system introduced by some enterprises has injected new vitality into the energy saving and consumption reduction of papermaking process. By installing various sensors on the production line, the intelligent system can monitor various key parameters in the production process in real time, including pulp concentration, temperature, equipment operation status, etc. These sensors are like "smart eyes" on the production line, always paying attention to every detail of production, and transmitting the collected data to the control system in real time.Based on these real-time data, the control system uses advanced algorithms and intelligent decision-making technologies to automatically adjust the operating parameters of the equipment to keep the production process in the best state. When the sensor detects that the slurry flow rate is too fast, resulting in uneven fiber distribution, the control system will respond quickly, automatically reduce the slurry flow rate, and adjust the running speed of the wire section to ensure the quality of the paperboard. This intelligent real-time monitoring and automatic adjustment effectively avoids errors caused by manual operation. In the traditional production process, manual operation often makes it difficult to achieve real-time and accurate control of production parameters, which can easily lead to deviations from the optimal state of the production process due to human factors, increasing energy consumption. The application of intelligent systems enables the production process to be dynamically optimized according to actual conditions, further reducing energy consumption. 4. Dehydration process: efficient technology, reducing energy consumptionIn the dehydration process of papermaking, efficient vacuum dehydration equipment and pressing technology play a vital role. Traditional dehydration methods are inefficient and require a lot of energy to achieve dehydration and drying of paperboard. In traditional processes, it may take a long time of high-temperature drying or multiple mechanical extrusions to remove moisture from the paperboard, which not only consumes a lot of energy, but also easily has an adverse effect on the quality of the paperboard.The efficient vacuum dehydration equipment can quickly remove moisture from the paperboard at a lower temperature through innovative technical design. Vacuum dehydration equipment uses a vacuum environment to lower the boiling point of water, allowing the water in the paperboard to evaporate quickly at a lower temperature, thereby reducing energy consumption during the drying process. Advanced pressing technology can squeeze out the water in the paperboard more evenly by optimizing the pressing pressure and time. By precisely controlling the pressing pressure and time, the pressing equipment can maximize the dehydration effect while reducing energy consumption without damaging the paperboard fibers. The application of these advanced technologies has significantly improved the energy efficiency of the dehydration process while ensuring the quality of the paperboard, making an important contribution to energy saving and consumption reduction in the papermaking process.

1. Basic advantages of bamboo pulp paper: toughness of natural fibersThe raw material of bamboo pulp paper comes from bamboo. As a fast-growing natural plant, bamboo pulp paper has high fiber strength. Compared with traditional wood pulp paper, bamboo pulp paper has more slender and tough fibers, so it performs well in strength and wear resistance. Bamboo pulp paper has better tear resistance and durability, and can better protect packaged items during daily transportation, storage, etc., and reduce damage caused by external forces.In contrast, the fiber structure of traditional wood pulp paper is relatively loose, which makes it more prone to deformation and cracking when subjected to pressure, friction or other external forces. Especially when exposed to humid or greasy environments for a long time, ordinary wood pulp paper is prone to softening and breakage, which is undoubtedly a major defect for packaging materials. 2. PLA coating improves paper strength and durabilityOn the basis of bamboo pulp paper, the addition of coating materials greatly improves its physical properties. Among them, the use of PLA (polylactic acid) coating is undoubtedly the key. PLA is a bio-based material fermented from plants, which has a good surface strength improvement effect. When PLA coating is applied to the surface of bamboo pulp paper, it not only makes the surface of the paper smoother, but also significantly enhances the tear resistance, water resistance and oil resistance of the paper. These enhanced properties make customized PLA coated bamboo pulp paper a more durable and adaptable packaging material for a variety of environments.PLA coating can effectively prevent the softening and deformation of paper when exposed to humid or high-moisture environments for a long time. Ordinary paper is easily softened and even cracked in a humid environment due to moisture. However, PLA coated bamboo pulp paper can effectively prevent moisture penetration, maintain its strength and structural stability, and extend the service life of packaging materials. Especially in the field of food packaging, the improvement of water resistance and oil resistance makes this material an ideal choice. 3. Improve tear resistance: cope with long-term transportation and storageIn logistics and supply chains, packaging materials often need to go through transportation, storage and other processes, and withstand long-term friction, collision and extrusion.

In contrast, ordinary paper is prone to cracks or damage when encountering impact and pressure, especially under high pressure. Therefore, the durability of customized PLA coated bamboo pulp paper makes it the preferred packaging material for many commodities that need to be transported and stored for a long time. 4. Oil resistance and environmental protection performance: provide protection for green packagingAs consumers' demand for green environmental protection continues to increase, the market demand for packaging materials with environmental protection performance is also continuing to rise. Customized PLA coated bamboo pulp paper has become an important choice in the field of green packaging due to its excellent environmental protection performance. PLA, as a biodegradable material extracted from plants, can not only degrade into carbon dioxide and water, but also effectively reduce the burden of traditional plastic packaging on the environment.In addition to environmental protection, PLA coated bamboo pulp paper also has obvious advantages in oil resistance. In many food packaging scenarios, oil penetration is a major challenge facing packaging materials. PLA coating can effectively prevent grease from penetrating into the paper, maintaining the integrity and cleanliness of the packaging material. This feature makes customized PLA coated bamboo pulp paper particularly widely used in the catering, food and other industries.

Ordinary papermaking equipment has its shortcomings. How to accurately control Custom Wood Pulp White Paperboard equipment? 1. High-precision equipment lays a solid foundation 1. Accurately control the forming of the mesh The first step in the papermaking process is to convert the prepared wood pulp into paperboard, and high-precision papermaking equipment plays a core role in this process. In the mesh forming stage, the papermaking equipment used for Custom Wood Pulp White Paperboard has excellent precision control capabilities. Through advanced sensors and automatic control systems, the flow rate, flow rate and running speed of the pulp can be accurately adjusted. The precise control of these parameters is crucial for the uniform distribution of wood pulp fibers on the mesh. When the pulp is delivered to the mesh at a precisely controlled flow rate and flow rate, the running speed of the mesh is perfectly matched, so that the wood pulp fibers can be evenly settled on the mesh to form a wet paper web with consistent thickness. In contrast, ordinary paperboard papermaking equipment is difficult to accurately adjust these parameters due to its limited precision. In the ordinary papermaking process, the pulp flow rate is unstable, the flow rate fluctuates, and the running speed of the mesh is difficult to accurately match the pulp supply, which leads to uneven distribution of wood pulp fibers in the mesh, resulting in uneven thickness of the cardboard. This uneven thickness not only affects the flatness of the appearance of the cardboard, making it look uneven, but also leads to uneven strength distribution of the cardboard. In the subsequent use process, the thinner parts become weak points and are prone to damage, which seriously affects the performance of the cardboard.2. Equipment support for optimizing the internal structureAdvanced papermaking equipment also provides strong support for optimizing the internal structure of the cardboard. Through specially designed forming devices, wood pulp fibers can be guided to form an orderly arrangement inside the cardboard. In ordinary cardboard papermaking, wood pulp fibers are often randomly arranged and lack orderliness, which limits the improvement of cardboard strength and stability. The papermaking equipment for customized wood pulp white cardboard can use special mechanical forces and fluid mechanics principles during the forming process to arrange wood pulp fibers in a specific direction, like neatly arranged soldiers, greatly enhancing the bonding force between the fibers inside the cardboard.After the cardboard is formed, it needs to go through the pressing and dehydration process to remove excess water and make the cardboard more compact. The papermaking equipment for customized wood pulp white cardboard also performs well in this link. The high-precision pressing equipment can accurately control the pressing pressure and time according to the characteristics of the cardboard to ensure that the water is fully squeezed out without over-squeezing and causing fiber damage. The dehydration equipment also uses advanced technology to efficiently remove moisture from the cardboard and further improve the density and strength of the cardboard. These processes require the coordinated cooperation of high-precision equipment, and the precise control of each link lays the foundation for ensuring the stability of cardboard quality. 2. Advanced papermaking methods to improve cardboard quality 1. Special molding process enhances strength The advanced papermaking method used in customized wood pulp white cardboard focuses on optimizing the internal structure of the cardboard, among which the special molding process is the key. This molding process uses innovative design and operation methods to enable the wood pulp fibers to form an orderly arrangement inside the cardboard. During the molding process, by controlling the flow path and speed of the pulp and applying a specific external force field, the wood pulp fibers are guided to interweave and arrange in a certain direction. This orderly arranged fiber structure greatly enhances the strength of the cardboard. When the cardboard is subjected to external forces, the orderly arranged fibers can better cooperate to resist the external forces, just like tightly woven ropes, which can withstand greater tension and pressure than randomly arranged fibers. In practical applications, for example, when packaging large and heavy items, customized wood pulp white cardboard can provide reliable support and protection with its optimized internal structure, effectively avoiding damage during transportation due to weight failure.2. Multi-process collaboration to ensure qualityAdvanced papermaking methods are also reflected in the coordination of multiple processes. From the formation of wood pulp on the net to the completion of the final cardboard, each process is closely connected and affects each other. In the dehydration process, efficient dehydration equipment can quickly and evenly remove moisture from the cardboard, making the structure of the cardboard tighter. The dehydration process not only affects the moisture content of the cardboard, but also affects the bonding force between the fibers. By precisely controlling the dehydration time and temperature, the hydrogen bonds between the fibers can be made stronger, further enhancing the strength and stability of the cardboard.In the subsequent drying process, the temperature and time also need to be precisely controlled to ensure that the cardboard is dried evenly and avoid deformation of the cardboard due to uneven drying. Advanced papermaking methods ensure the quality of paperboard from multiple aspects through precise control and coordination of each process, so that it has reached a high level in strength, flatness, stability and other aspects. 3. Special calendering process improves surface quality 1. High-precision pressure regulation Special calendering process is the key link to improve the surface flatness and finish of paperboard. During the calendering process, the Custom Wood Pulp White Paperboard passes through a series of rollers under high temperature and high pressure. The calendering equipment used in the Custom Wood Pulp White Paperboard has a high-precision pressure regulation system, which is the core technology for achieving high-quality calendering. The system can accurately adjust the calendering pressure according to the different requirements of the paperboard.For paperboards of different thicknesses, materials and uses, the required calendering pressure is different. The high-precision pressure regulation system can quickly and accurately adjust the pressure between the rollers according to the specific parameters of the paperboard, so that the surface of the paperboard is subjected to uniform and appropriate pressure. This precise pressure control can effectively eliminate the tiny unevenness on the surface of the paperboard, so that its surface can achieve extremely high flatness. In contrast, the calendering equipment of ordinary cardboard has limited pressure adjustment accuracy, which makes it difficult to make precise adjustments according to the specific conditions of the cardboard, resulting in poor calendering effect and obvious defects on the cardboard surface.2. Create an ideal printing carrierAfter high-precision calendering, the smoothness of the cardboard surface is greatly improved. This high flatness and smoothness surface provides an ideal carrier for high-quality printing. During the printing process, the ink can be evenly attached to the surface of the cardboard, ensuring that the printed pattern is clear and colorful. The high flatness surface can also reduce the penetration and diffusion of the ink, making the edges of the printed pattern sharper and the details richer.In the field of high-end packaging printing, the requirements for printing quality are extremely high. The surface quality of customized wood pulp white cardboard after special calendering process can meet these strict requirements. Whether it is exquisite pattern design or delicate text printing, it can be perfectly presented on customized wood pulp white cardboard. In cosmetic packaging printing, the metallic texture, three-dimensional relief and other effects presented on the surface of customized wood pulp white cardboard through special printing technology are precisely due to its high flatness and smooth surface, which adds a unique charm to the product packaging and enhances the added value of the product.

1. High strength: a solid line of defense against external impactsKraft Paperboard's high strength is mainly due to its unique fiber structure and manufacturing process. Kraft paperboard is mainly made of long-fiber softwood pulp or hardwood pulp, which are tightly combined through a fine papermaking process to form a strong fiber network. This structure gives Kraft paperboard excellent tensile and compressive strength, allowing it to withstand large external forces without easily deforming or breaking. In extreme climatic conditions, such as strong winds, heavy rains, hail and other natural disasters, packaging materials often face severe tests. High-strength kraft paperboard can effectively resist these external impacts. In strong winds, packaging boxes may be violently shaken and squeezed, but the high-strength structure of kraft paperboard can maintain its integrity and prevent internal items from being damaged due to packaging ruptures. Similarly, in heavy rain or hail weather, kraft paperboard can withstand the impact of water droplets or hail, avoiding damage to the packaging surface, thereby protecting internal items from moisture or physical damage. The high strength of kraft paperboard is also reflected in its load-bearing capacity. During logistics transportation, packaging boxes often need to be stacked to save space. High-strength kraft paperboard can withstand greater stacking pressure, ensuring that the packaging boxes will not deform or collapse due to excessive load during stacking, thereby protecting the safety of internal items. 2. Tear resistance: a key feature to prevent packaging damageTear resistance is another crucial feature of kraft paperboard. It refers to the ability of paperboard to remain intact and not easily broken when torn by external force. This feature is crucial for packaging materials because it is directly related to the protective effect of packaging during transportation and storage. Under extreme climatic conditions, packaging materials may become more fragile due to factors such as moisture, temperature changes or mechanical stress. At this time, tear resistance is particularly important. The tear resistance of kraft paperboard is mainly due to the close bonding between its fibers and the toughness of the fibers themselves. When the packaging is subjected to tearing force, these tightly bonded fibers can jointly withstand the external force to prevent the paperboard from breaking. The toughness of the fiber can also absorb part of the tearing energy, further enhancing the tear resistance of the paperboard. The importance of tear resistance is self-evident when dealing with extreme climates. In extreme weather such as hurricanes or typhoons, packaging materials may be torn by strong winds. If the packaging material does not have sufficient tear resistance, it will be easily torn, causing the internal items to be exposed and damaged. Kraft paperboard, with its excellent tear resistance, can maintain the integrity of the packaging under such extreme conditions and ensure the safety of the internal items. 3. The combined role of high strength and tear resistance in dealing with extreme climatesAs the two core characteristics of kraft paperboard, high strength and tear resistance play a vital role in dealing with extreme climates. Together, they form a solid line of defense for packaging materials, which can resist external impacts and prevent packaging damage, thereby protecting the internal items from damage. Under extreme climatic conditions, such as natural disasters such as heavy rains, floods, and hurricanes, packaging materials often face multiple challenges. High-strength kraft paperboard can withstand large external impacts and stacking pressure to ensure the integrity of the packaging; while tear resistance can prevent the packaging from breaking when subjected to tearing force, further protecting the safety of the internal items. These two characteristics complement each other and jointly enhance the protective effect of kraft paperboard under extreme climatic conditions. The high strength and tear resistance of kraft paperboard also bring it a wider range of application prospects. In the fields of e-commerce, cold chain logistics, military packaging, etc., these characteristics make kraft paperboard an ideal choice of packaging material. They can not only meet the basic needs of packaging, but also provide additional protection under extreme climatic conditions to ensure the safe delivery of the packaged items.

1. Control of pulp preparationPulp preparation is the first step in large rolls paper production and is also the basic link that affects paper quality. In the process of pulp preparation, the following key parameters need to be strictly controlled:Fiber decomposition: The degree of fiber decomposition directly affects the uniformity of pulp and the strength of paper. In order to ensure that the fibers are fully decompressed, appropriate decomposition equipment and process conditions need to be adopted, such as using efficient decomposition machines, controlling decomposition time and temperature, etc.Control of beating degree: The beating degree refers to the degree to which pulp fibers are cut, swollen, fibrillated, and dispersed. Too high or too low beating will affect the quality of paper. If the beating degree is too high, the fibers are too short and the strength of paper is reduced; if the beating degree is too low, the fibers are not fully interwoven and the uniformity of paper is poor. The beating degree needs to be accurately controlled according to the purpose and quality requirements of paper.Pulping uniformity: Pulping is the process of mixing different types of pulp in a certain proportion. The uniformity of pulping directly affects the uniformity and strength of paper. In order to ensure uniform pulping, advanced pulping equipment and processes are required, such as using an automated pulping system, controlling the pulping ratio and stirring time, etc. 2. Control of paper formingPaper forming is the process of dehydrating and interweaving pulp on a forming net to form paper. During the paper forming process, the following key parameters need to be strictly controlled: Tension of the forming net: The tension of the forming net affects the thickness uniformity and surface flatness of the paper. If the tension is too large, the paper is easy to break; if the tension is too small, the paper is easy to wrinkle. The tension of the forming net needs to be accurately adjusted according to the paper quality and equipment requirements.Height of the forming box: The height of the forming box determines the dehydration speed of the pulp on the forming net and the thickness of the paper. If the height of the forming box is too high, the paper is not fully dehydrated and the thickness is uneven; if the height of the forming box is too low, the paper is dehydrated too quickly and cracks are easy to occur. The height of the forming box needs to be reasonably set according to the purpose of the paper and the equipment conditions.Moisture content of paper: The moisture content of paper is one of the key factors affecting the flatness and strength of paper. During the paper forming process, the moisture content of the paper needs to be controlled within an appropriate range to ensure the stability and quality of the paper. This is usually achieved by adjusting the running speed of the forming network, the pressure and temperature of the dewatering equipment and other parameters. 3. Control of paper pressingThe pressing process is a key step to remove excess water from the paper and improve the compactness and strength of the paper. During the pressing process, the following key parameters need to be strictly controlled:Pressing pressure: The size of the pressing pressure directly affects the compactness and moisture removal efficiency of the paper. If the pressing pressure is too large, the paper is easily crushed; if the pressing pressure is too small, the paper is not compact enough. The pressing pressure needs to be accurately adjusted according to the purpose of the paper and the equipment conditions.Pressing time: The length of the pressing time will also affect the compactness and moisture removal efficiency of the paper. If the pressing time is too long, the paper is easily crushed; if the pressing time is too short, the paper is not compact enough. The pressing time needs to be set reasonably to ensure that the compactness and moisture removal efficiency of the paper are optimally balanced.Material and surface condition of the pressing roller: The material and surface condition of the pressing roller also have an important influence on the flatness and strength of the paper. Using suitable pressing roller materials and maintaining good surface conditions can improve the flatness and strength of the paper. 4. Control of paper dryingThe drying process is to evaporate the water in the paper so that the paper reaches the predetermined dryness and strength. During the drying process, the following key parameters need to be strictly controlled:Drying temperature: The drying temperature directly affects the drying speed and dryness of the paper. If the drying temperature is too high, the paper is easy to shrink and deform; if the drying temperature is too low, the paper is not fully dried. The drying temperature needs to be set reasonably according to the purpose of the paper and the equipment conditions.Drying wind speed: The size of the drying wind speed will also affect the drying speed and dryness of the paper. If the drying wind speed is too high, the paper is easily blown by the wind, affecting the flatness; if the drying wind speed is too low, the paper is not fully dried. The drying wind speed needs to be reasonably adjusted to ensure that the drying speed and dryness of the paper reach the best balance.Structure and layout of drying equipment: The structure and layout of drying equipment also have an important impact on the flatness and strength of the paper. The use of advanced drying equipment and reasonable layout methods can improve the flatness and strength of the paper. The use of multi-stage drying equipment and control of parameters such as the temperature and wind speed of each drying stage can further improve the quality of the paper.
