Mica powder is a kind of non-metallic mineral, which contains a variety of components, mainly including SiO2, the content is generally about 49%, and the content of Al2O3 is about 30%. Melting and casting synthetic mica, mica has good elasticity and toughness. Insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesion and other characteristics, is an excellent additive. It is widely used in paints, coatings, pigments, plastics, papermaking, cosmetics, new building materials and other industries, and has an extremely wide range of uses. With the continuous development of science and technology, the application of mica in industry has grown rapidly.

Industrial uses of mica

The most widely used in industry is muscovite, followed by phlogopite. It is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding rod, plastic, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments and other chemical industries. Ultrafine mica powder is used as functional filler for plastics, coatings, paints, rubbers, etc., which can improve its mechanical strength, enhance toughness, adhesion, aging resistance and corrosion resistance. In addition to its extremely high electrical insulation, acid and alkali corrosion resistance, elasticity, toughness and sliding properties, heat and sound insulation, and small thermal expansion coefficient, it is also the first to introduce smooth surface, large diameter-to-thickness ratio, regular shape, attached Features such as strong focus.

In industry, its insulation and heat resistance, as well as acid resistance, alkali resistance, compression resistance and peeling resistance are mainly used as insulating materials for electrical equipment and electrical equipment; secondly, it is used to manufacture steam boilers and smelting furnaces. Windows and mechanical parts.

Mica crushed and mica powder can be processed into mica paper, and can also replace mica sheet to manufacture various insulating materials with low cost and uniform thickness.
