Manufacturing Method of Semi-Matte Slices
In the field of raw materials for chemical production, Semi-Matte Slices is an important product, which is widely used in the fields of plastics, fibers, films and so on. This article will introduce the manufacturing method of semi-matte slices, including raw material selection, production process, equipment selection and other aspects.
I. Raw material selection
The main raw materials for manufacturing semi-darkening slices are polymer compounds, such as polyethylene, polypropylene and so on. In order to obtain high-quality semi-emissive slices, it is necessary to choose raw materials with high purity, good fluidity and uniform molecular weight distribution. In addition, it is also necessary to add an appropriate amount of additives according to the product requirements, such as antioxidants, antistatic agents and so on.
II. Production process
The manufacturing process of semi-matte slices mainly includes the following steps:
1. Batching: Mix the raw materials and additives together according to a certain proportion to make the material to be processed.
2. Melting and extruding: Add the ingredients into the extruder, melt and plasticize the materials through high temperature and shear effect to form a continuous and stable melt.
3. Filtration: Impurities and gel particles in the melt are removed through filters to ensure the quality and transparency of the product.
4. Stretching: The filtered melt is stretched to increase its orientation and molecular weight and improve the mechanical properties of the slices.
5. Cooling and shaping: The stretched melt is cooled and shaped to form semi-matte slices of certain thickness and width.
6. Edge cutting and coiling: Cutting and coiling the cooled and shaped slices to get the final semi-matte slices. Equipment selection
The manufacture of semi-matte slices requires extruders, filters, stretching machines, cooling devices, edge cutting devices and winding devices and other equipment. When selecting equipment, it is necessary to make comprehensive consideration according to factors such as the output of products, quality requirements and production process, and select the equipment with stable performance, easy operation and convenient maintenance.
Four, production notes
1. Strictly control the quality and proportion of raw materials to ensure product stability and consistency.
2. Keep the equipment clean and hygienic during the production process, carry out regular inspection and maintenance to ensure the normal operation of the equipment.
3. Enhance the monitoring and adjustment of temperature, pressure, speed and other parameters during the production process to ensure product quality and yield.
4. Pay attention to safe production, comply with relevant regulations and standards, and ensure the personal safety and health of employees.
In short, the manufacturing method of semi-matte slices needs to comprehensively consider the factors of raw material selection, production process, equipment selection, etc., in order to ensure the quality and yield of the products. Meanwhile, management and monitoring need to be strengthened during the production process to ensure the safety and stability of production.
