The following are some application cases of rubber rolls in the rubber processing industry:
Rubber mixing: In the rubber mixing process, the rubber roll is used to mix the raw rubber with various compounding agents such as carbon black, sulfur, accelerator, etc. Through the extrusion and shear action of the roll, the compound can be evenly dispersed in the rubber matrix, and the performance consistency of the compound can be improved. For example, in the mixing of tire compounds, the use of rubber rolls can ensure that fillers such as carbon black are evenly dispersed, thereby improving the wear resistance and strength of the tire.
Film rolling: The rubber roll of the rolling machine can press the mixed rubber material into a film with a certain thickness and width. For example, in the production of rubber conveyor belts, the rubber material is rolled into film of different thicknesses by rubber rollers, and then bonded with the fabric layer, and the conveyor belt is made by vulcanization and other processes. The rubber roll can control the thickness accuracy and surface smoothness of the film during the calendering process to provide high-quality film for subsequent processing.
Rubber molding: In the molding process of rubber products, rubber rolls also play an important role. For example, in the production of rubber soles, the mixed rubber material is pressed into a rubber embryo with a certain shape and thickness by a rubber roll, and then the finished sole is made by a process such as mold vulcanization. The rubber roll can ensure the dimensional accuracy and surface quality of the rubber embryo and improve the forming quality of the sole.
Rubber and fabric bonding: For some rubber products that need to be compounded with rubber and fabric, such as rubber cloth, rubber rolls are used to fit rubber sheets and fabric tightly together. In the process of laminating, the rubber roll exerts a certain pressure, so that the rubber can fully penetrate into the gap of the fabric, forming a firm bond, so as to improve the comprehensive performance of rubber products.
