Mica powder is a kind of non-metallic mineral containing many kinds of components, with the content of SiO2 and Al2O3 being the highest. It can be used as rubber filling reinforcing material in rubber field. Reclaimed rubber can be used as the third largest rubber species with large dosage. Some reclaimed rubber products The processing also needs mica powder. Xiao Bian today from the performance of mica, advantages, usage and other aspects and we carefully talk about renewable mica powder.
1, mica powder performance: mica powder with a unique composition and structure in, not only has good flexibility, toughness, its insulation, high temperature, acid and alkali, corrosion resistance, adhesion is also very strong, is recycled plastic products The production of an excellent reinforcing filler.
2, the reasons for the addition of recycled mica mica powder: Mica powder with a high diameter-thickness ratio of the unique structure, can enhance the reinforcing effect of recycled rubber; excellent flaky crystal form, can greatly improve the airtight, its own mineral crystal Polarization effect and inter-layer water molecules interference effect, which can effectively shield ultraviolet, microwave and infrared rays, and greatly improve the aging resistance of reclaimed rubber products.
3, mica powder in the reclaimed rubber products in the use and dosage: tire, tape, plastic sheet, hose, rubber and other automotive rubber products are inseparable from the production of mica powder, some data show that sericite powder has good processing properties , Can replace 30-50% semi-reinforcing or other coarse particles carbon black, or the original formula to increase a certain percentage of sericite powder, to maintain the same rubber properties, while reducing product costs.
4, Sericite powder plays an important role in reclaimed rubber products: sericite powder in mica powder is used frequently in the production of reclaimed rubber products, which can be used as soft lubricant, mold release agent and hygroscopic agent to improve regeneration Anti-corrosion of plastic products, anti-cracking high temperature performance; sericite powder can replace the territories, clay, light calcium as a reclaimed rubber products filler, but also can replace the production of transparent reclaimed white silica gel products such as transparent soles, reinforcing , Abrasion resistance, good thermal conductivity; coated surface coated with recycled sericite powder to prevent rubber sticky.
Reclaimed rubber products used in the formulation of mica powder can improve the mechanical strength of reclaimed rubber, reinforcing, heat resistance, abrasion resistance and corrosion resistance, tear resistance, is an important agent in the production of recycled rubber products.
