SA Series-Wollastonite Superfine Powder
Classification:
Wollastonite ultrafine powder, also known as wollastonite ultrafine powder, is a finely processed wollastonite powder. It typically has a particle size of less than 10 microns, a fibrous, needle-like morphology, and an aspect ratio of greater than 10:1. This powder is a white or slightly light gray inorganic non-metallic material with high whiteness, good insulation, dielectric properties, heat resistance and weather resistance.

This powder is a white or slightly light gray inorganic non-metallic material with high whiteness, good insulation, dielectric properties, heat resistance and weather resistance.
The superfine wollastonite powder is widely used in many fields. First of all, in the paint, plastic and rubber industries, it can be used as a filler and reinforcing agent to improve the strength, hardness, wear resistance and weather resistance of the product. Secondly, in the cable industry, superfine wollastonite powder can be used as a cable filler to increase the insulation and heat resistance of the cable. In addition, the ultra-fine wollastonite powder can also be used for rubber and plastic reinforcing agents, fibrous fillers for friction materials of clutch brakes such as automobiles, etc.
In the process of preparing superfine wollastonite powder, a series of wollastonite powder making equipment is needed, such as jaw crusher, fine jaw crusher, vibrating feeder, bucket elevator, superfine wollastonite mill, belt conveyor, dust removal device, etc. These devices have compact combination, small occupied space, convenient particle size adjustment and simple operation, and can realize the preparation of highly efficient and environmentally friendly fine wollastonite powder.
In general, wollastonite ultrafine powder is a kind of inorganic non-metallic material with wide application and good market prospect. Its special crystal morphology and properties make it have important application value in many fields such as paint, plastic, rubber, cable and so on. With the progress of science and technology and the improvement of environmental awareness, the application field of superfine wollastonite powder will continue to expand, and the market demand will continue to grow.
