Broken grinding system of talcum for silicon rubber production
Technical Field
The invention belongs to the technical field of rubber production, and particularly relates to a talc crushing and grinding system for silicon rubber production.
Background
With the rapid development of modern industry, especially chemical industry, rubber products are in various types, but the production process is basically the same, and products using general solid rubber (raw rubber) as raw material mainly comprise the following steps: preparing raw materials, plasticating, mixing, molding, vulcanizing, finishing and inspecting. The main materials of the rubber product comprise raw rubber, a compounding agent, a fiber material and a metal material. Certain materials need to be processed in order to allow the raw rubber and the compounding ingredients to be uniformly mixed with each other. Lumpy compounding agents such as paraffin, stearic acid, rosin, talc and the like are required to be pulverized, wherein talc is used as a filler for rubber.
talc is a kind of "metamorphic mineral" in which magnesium rocks are usually metamorphic, and is formed by long-term physical and chemical changes of other minerals in the ground. For example dolomite, consisting of magnesium carbonate, can be transformed into hydrated magnesium silicate, talc, as the major component by hydrothermal action at high temperatures, rich in silicon. Some rocks containing other magnesium silicates, such as olivine, enstatite, and hornblende, also undergo component rearrangement in a similar process, converting to talc. Talc is generally in the form of blocks, leaves, fibers or radial, is white, off-white in color, and can be variously colored due to the inclusion of other impurities. Talc is used in many applications, such as fire-resistant materials, paper making, rubber fillers, pesticide absorbents, leather coatings, cosmetic materials, carving materials, and the like.
The talcum powder is ground into powder when in use, and has wide application range, for example, the talcum powder is used in rubber, so that the volume of the rubber can be increased, the processability of the rubber can be improved, the semi-reinforcing or reinforcing effect can be realized, and the hardness of the rubber can be adjusted. In the coating, the talcum powder is used as a filler, so that the function of a framework can be achieved, the manufacturing cost is reduced, and the film hardness of the coating is improved. In the plastic, the volume of the plastic can be increased, the product cost can be reduced, the dimensional stability of the plastic and the hardness and rigidity of the plastic can be improved, and the talcum powder can improve the heat resistance and the light scattering property of the plastic. In the existing grinding modes, the ground talc has a rubble structure, the particle size is not uniform, the shape is irregular, and the quality of a final product is influenced.
