Stone paper, also known as non wood pulp paper or mineral paper, is mainly made from raw materials such as calcium carbonate and resin. Due to its excellent waterproof, oil resistant, tear resistant, and environmentally friendly properties, it is widely used in packaging, labeling, stationery, and other fields. The blown film production line for stone paper is a process of extruding and blowing modified resin and fillers such as calcium carbonate to form a thin film. During this process, temperature control is crucial and directly affects the physical properties and processing efficiency of the product.
1. Temperature range
The operating temperature of the blown film production line for stone paper is generally recommended to be controlled between 180 ° C and 220 ° C. The specific temperature setting depends on the type of resin used, the filling ratio of calcium carbonate, and the specific situation of the production line equipment.
2. Temperature control of each section
In the blown film production process of stone paper, different sections of the equipment have different temperature requirements:
Extruder section: The temperature of this section should be maintained between 180 ° C and 220 ° C. The temperature in the front area (feeding area) is relatively low, usually between 160 ° C and 180 ° C, so that the material can be smoothly fed. The temperature in the back area gradually increases, which helps plasticize the material and ensures good fluidity and mixing.
Mold head temperature: The mold head temperature is usually between 200 ° C and 220 ° C. Appropriate temperature can ensure good flowability of materials when passing through the mold head, prevent blockage, and ensure the uniformity and quality of the membrane.
Inflation zone temperature: The temperature of inflation during film processing should be maintained between 190 ° C and 210 ° C. This helps the membrane maintain sufficient temperature before cooling, forming good internal stress within the membrane through rapid contact with cold air, ensuring uniform thickness of the membrane.
3. The impact of temperature control on product properties
Physical properties: Temperature control has a significant impact on the physical properties such as strength, toughness, and transparency of the final product. Low temperature may lead to insufficient plasticization, resulting in insufficient strength of the film; Excessive temperature may cause resin decomposition or degradation, affecting the appearance and performance of the membrane.
Production efficiency: Under suitable temperature conditions, the flowability of materials is good, which can improve production efficiency, reduce downtime and material waste. Improper temperature control can lead to instability in the production process, increase equipment burden, and even cause equipment failure.
4. Other precautions
Temperature monitoring: A temperature monitoring system should be installed during the production process to monitor real-time temperature changes in each section. Combined with data analysis, adjust the temperature in a timely manner to cope with changes in material properties and different production environments.
Environmental factors: The humidity and temperature of the production environment can also affect the processing efficiency of stone paper. Properly controlling the production environment can help improve production stability.
summary
Controlling the operating temperature of the stone paper blown film production line between 180 ° C and 220 ° C is key to ensuring product quality and production efficiency. By finely regulating the temperature of different sections, the plasticization process of materials can be optimized, the physical properties of products can be enhanced, and market demand can be met. Manufacturers also need to pay attention to temperature monitoring and adjustment during actual operation to ensure efficient and stable operation of the equipment.
