The production line process of PVC sheet mainly includes the following key steps:
1. Raw materials: Prepare PVC resin, stabilizer, lubricant, filler, pigment and other raw materials. These raw materials need to be mixed in a certain proportion to ensure the quality of the final product.
2. Mixing: In the mixing process, various raw materials need to be put into the mixer in accordance with a certain proportion for mixing. The mixer thoroughly mixes the raw materials to ensure the uniformity and stability of the final product.
3 Extrusion: In the extruder, the mixed raw materials will be heated to a certain temperature, and then extruded through the screw of the extruder. In the extrusion process, the raw material will be extruded into a certain shape of the sheet, this process needs to control the temperature and extrusion speed of the extruder to ensure the quality of the final product.
4. Cooling: After extrusion, the plate needs to be cooled by the cooling machine to make it reach a certain hardness and stability. Chillers usually use water cooling or wind cooling to achieve the best cooling effect.
5. Cutting: After cooling, the sheet will be fed into the cutting machine for cutting. The cutting machine will cut the sheet according to a certain size to meet the needs of different customers.
Through the above steps, the PVC sheet production line can efficiently and stably produce sheets that meet the quality requirements.
