Calendering process: 1, batching. Accurately weigh the resin and various additives according to the formula proportion. 2. rub. The components are added into the kneader in a predetermined order and fully mixed to ensure that the components are evenly dispersed and infiltrated. 3. Plasticizing. Using an internal mixer, a high-speed kneader or an extruder, the mixture is heated to the viscous flow temperature, and the components are fully sheared, mixed, soaked and melted through the strong shearing action of a plasticizing machine, so as to achieve uniform mixing of raw materials, uniform temperature and air, and uniform viscosity. 4. hello. You can use a roller press or an extruder to feed plasticized materials into a calender through a transmission device. At the same time, it has further plasticizing effect. 5. calendering. Using a calender, the plastic is extruded into a film or sheet with a predetermined size at a preset temperature √ speed. 6. lead the way. The film or sheet is separated from the calendering roll by the pull-off roll. 7. embossing. The embossing roller and rubber roller work together to get a certain pattern on the surface of the product. 8, cooling. After the film or sheet is formed, it is cooled and shaped by several groups of cooling rollers. 9. transportation. The molded product passes through the conveyor belt, and the product is conveyed to the next process in a relaxed state. 10, roll cutting. Roll the product into a roll, which is convenient for storage and transportation.
