The rubber mastication, the purpose is to change the performance of the rubber to improve the processing properties of the plastic material plasticity, fluidity, viscosity and rubber. With the increasing plasticity of the rubber, the mechanical strength of the vulcanized rubber is reduced, the permanent deformation increases plasticity increases. General masticated rubber roller to pull up a thin layer uniformity of rubber, can not see the cornstarch until transparent. Mixing: rubber and compounding ingredients in the mixing device (mixer, mixing machine) evenly mixed compounds and masterbatch process. The uniformity and the degree of kneading of the kneaded product processing directly affect the performance and quality of performance. The rubber mixing purpose is masticated rubber material with other compounding ingredients mixed with each other seepage and the complexing agent uniformly dispersed in the rubber compound and complexing agent in the vulcanization play a variety of its due role. So after mixing with and glues material dispersed evenly, roll away from the complexing agent program, temperature and mixing time, must be based on the technical rules, otherwise it will affect the quality of the plastic material and extrusion, product quality resulting in an accident. The test rubber mixing quality in addition to some test means can also be pulled thin rubber watch rubber, granular or lump material, so that you can basic judgment to the rubber processing uniformity.
