Wollastonite may not be familiar, but the plastic objects used in our daily life contain wollastonite. Wollastonite is a naturally produced calcium metasilicate mineral, which is widely used in ceramics, plastics, rubber, paint and coating industries. At present, in the plastic market, the use of wollastonite is increasing. Of course, in recent years, wollastonite has also become popular in the field of asbestos and glass. Wollastonite is used to manufacture lightweight, compression resistant, thermal insulation and insulating building materials, such as heat-resistant cardboard, white cement, special concrete and acid resistant glass. Wollastonite is a new type of electrical insulating material with high resistance and low dielectric constant, which can be used as a substitute for asbestos.
The natural wollastonite is crushed, screened and refined by a wollastonite superfine mill, and can be used as a filling material for plastics. However, if the performance of plastic filler is required to be high, the wollastonite prepared by synthetic method can be used, that is, silicon dioxide and calcium oxide can be prepared by heating reaction. Wollastonite is used as filler for plastics and rubber because of its low viscosity, high dispersion and low moisture absorption. Especially, the length diameter ratio of wollastonite crystal is large, and its acicular powder can be used as short fiber filler to reinforce various plastic composites. Wollastonite used as plastic mineral filler can increase strength, reduce water absorption, improve thermal and dimensional stability, and improve dielectric index and electrical insulation.
The wollastonite superfine mill can provide a series of processing for wollastonite, showing its skills in the plastic industry, driving the consumption of the superfine mill in the plastic industry, and expanding the application scope and customer market of the superfine mill.
