The process of rubber mixing is essentially a process in which the compounding agent is uniformly dispersed in the raw rubber, the granular compounding agent is in a dispersed phase, and the raw rubber is in a continuous phase. During the mixing process, the molecular structure, molecular weight and distribution of the rubber, and the aggregation state of the compounding agent all changed. Through mixing, rubber and compounding agents play a physical and chemical role, forming a new structure. A rubber compound is a dispersion system with complex structural characteristics. Due to the high viscosity of the raw rubber, in order to allow the compounding agent to penetrate into the raw rubber and uniformly mix and disperse therein, it is necessary to rely on the strong mechanical shearing action of the rubber mixer. The mixing process will vary depending on the type of mixer used. The rubber mixing machine mainly has two types: open type and closed type. The newer mixers are screw-transfer devices that save energy and floor space, reduce labor intensity, and facilitate continuous production.
