Multi - layer Co - extrusion Precision Control System: This system utilizes advanced computer programming and sensor technologies to precisely regulate the 11 - layer co - extrusion process. It can accurately set parameters such as the thickness, extrusion speed, and pressure of each layer of material according to different production requirements. For example, for film products that need to mainly block oxygen, the system will increase the thickness of the material layer with high oxygen - barrier performance and precisely control its combination ratio with other layers. This effectively blocks the penetration of various gases such as oxygen and carbon dioxide, as well as water vapor, ensuring that the film has excellent barrier properties.
Raw Material Purity Monitoring and Blending System: Before raw materials are put into production, this system conducts strict purity tests on each type of raw material. Through advanced technical means such as spectral analysis and chromatographic analysis, it ensures that the quality of the raw materials meets the requirements for high - barrier performance. At the same time, the system precisely blends the proportions of different raw materials according to the preset formula, ensuring the uniform distribution of materials in each barrier layer and laying the foundation for achieving stable and efficient barrier performance.
High - strength and Puncture - resistance Performance Construction System
Screw Plasticizing and Pressure Enhancement System: The high - performance screw design, combined with an intelligent pressure - regulating device, constitutes the screw plasticizing and pressure enhancement system. The special thread structure and material of the screw can fully plasticize high - strength raw materials, enabling the full integration of raw material molecules. Meanwhile, the system can automatically adjust the rotation speed and pressure of the screw according to the characteristics of the raw materials and production requirements, providing a strong and stable pressure for the extrusion process. As a result, the film forms a dense and high - strength structure, possessing excellent puncture - resistance performance.
Rapid and Uniform Cooling and Shaping System: This system consists of a specially designed cooling roll set and a precise temperature control system. The cooling rolls are made of special materials with high thermal conductivity and undergo precise surface treatment, enabling them to rapidly cool the extruded high - temperature film. The temperature control system can accurately adjust the temperature and cooling speed of the cooling rolls according to the thickness and material of the film, enabling the orderly arrangement of the film molecular chains, increasing the crystallinity and density of the film, and further enhancing its strength and puncture - resistance.
Good Heat - sealing Performance Realization System
Intelligent Heat - sealing Temperature and Pressure Control System: Equipped with high - precision temperature and pressure sensors, this system monitors the temperature and pressure changes during the heat - sealing process in real - time. The intelligent control system can automatically adjust the temperature and pressure of the heat - sealing knife according to the material, thickness, and heat - sealing requirements of the film, ensuring that the film in the heat - sealing area can quickly melt and firmly bond. For example, for thicker films, the system will appropriately increase the heat - sealing temperature and pressure to ensure heat - sealing strength; for thinner films, it will precisely control the parameters to avoid over - heat - sealing, which may damage the film.
Film Tension Stability Control System: Tension sensors and tension - regulating devices are set before and after the heat - sealing section of the production line to form the film tension stability control system. This system can detect the tension changes of the film in real - time and adjust the rotation speed and pressure of the traction rolls to keep the film at a constant tension during the heat - sealing process. Stable tension facilitates the smooth progress of the heat - sealing process, avoids film wrinkling or stretching deformation, and ensures the consistency and reliability of heat - sealing quality.
Good Temperature - resistance Performance Support System
Full - process Precise Temperature Control System: This system covers all key links of the production line, including the screw extruder, die head, cooling rolls, etc. Each link is equipped with an independent high - precision temperature sensor and heating/cooling device, and the precise adjustment of temperature is achieved through an intelligent control system. During the high - temperature extrusion process, the system can ensure that the raw materials are fully plasticized without thermal decomposition; during the cooling stage, it can quickly cool the film to an appropriate temperature, enabling the film to maintain stable physical properties in different temperature environments and have good temperature - resistance.
Temperature - resistant Material Adaptation and Protection System: This system automatically selects suitable temperature - resistant materials for the manufacture and protection of key components according to the temperature requirements of the production line. For example, for components such as screws, die heads, and pipelines in high - temperature areas, high - temperature - resistant alloy materials are used, and their surfaces are specially insulated; in low - temperature areas, low - temperature - resistant sealing and lubricating materials are selected to ensure that the production line can operate normally under high - or low - temperature conditions, and the produced film can also adapt to the corresponding temperature environment.
Excellent Chemical - resistance Performance Protection System
Corrosion - resistant Material Application and Monitoring System: For components in the production line that come into contact with raw materials, such as screws, barrels, and die - head flow channels, corrosion - resistant special alloy materials are used or special surface coating treatments are carried out. At the same time, the system monitors the corrosion situation of these components in real - time. By installing corrosion sensors and conducting regular non - destructive testing, potential corrosion problems can be detected in a timely manner, and a warning signal is issued so that maintenance measures can be taken promptly to ensure that the production line is not affected by chemical corrosion and to guarantee the chemical - resistance of the film.
Chemical Substance Cleaning and Purification System: A special cleaning system is set up to clean the production line either between the production of film products with different chemical properties or regularly. The cleaning system uses environmentally friendly cleaning agents, which can effectively remove the chemical substances remaining during the production process. At the same time, an exhaust gas purification device is equipped to treat the exhaust gas generated during the cleaning process, preventing the release of chemical substances into the environment, ensuring that the production environment meets environmental protection requirements, and guaranteeing that the film has no chemical pollution residue.
High Transparency and Gloss Enhancement System
Raw Material Purity Optimization System: This system deeply processes the raw materials used for producing high - transparency films through multi - stage filtration, drying, and impurity - removal processes. Before the raw materials enter the production line, they are first filtered through high - precision filters to remove impurities and tiny particles; then, vacuum drying is carried out to reduce the water content of the raw materials; finally, methods such as electrostatic adsorption are used to further remove tiny impurities in the raw materials, ensuring the purity of the raw materials and providing a high - quality basis for the production of high - transparency films.
Mirror - surface Molding and Surface Treatment System: High - precision mirror rolls and advanced surface treatment technologies are adopted. During the film - forming process, the highly polished surface of the mirror roll can make the film surface smooth and flat, improving the gloss of the film. At the same time, the system can also carry out special coating treatments on the film surface, such as coating brighteners or antistatic agents, further enhancing the transparency and gloss of the film, making the film present a clear and bright appearance.
Environmental - friendly Solvent - free Residue Assurance System
Solvent - free Raw Material Conveying and Handling System: Fully enclosed raw material conveying pipelines and solvent - free raw material storage equipment are used to avoid introducing solvents during the raw material conveying and storage processes. At the same time, in the processing of raw materials, such as in the mixing and plasticizing steps, organic solvents are not used, ensuring that the raw materials enter the production line in a pure state and reducing the possibility of solvent residue from the source.
Exhaust Gas and Waste Purification and Treatment System: High - efficiency exhaust gas collection and purification devices are equipped to treat the small amount of exhaust gas generated during the production process. Through technologies such as adsorption and catalytic combustion, volatile organic compounds (VOCs) in the exhaust gas are removed to meet environmental protection emission standards. At the same time, the waste generated during the production process is classified, collected, and recycled to achieve the recycling of resources, ensuring that the entire production process meets environmental protection requirements and that the produced film has no solvent - residue pollution.
