3.Main Application:
(1) Used in decorating, paint and coating.
(2) Mica powder is the basic raw material for mica ceramics products.
(3) It can be used in fire-fighting dry powder, protecting layer of welding rods, conducting wires and electric cables.
(4)It can be taken as a filler, shelter, lubricating substance, drawing of patterns in plastics, rubber, asbestos products and sealing materials. It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products. It can be used as coating in models of forcasting metal, the brightening material in aluminium and paint in electroplating bath.
Muscovite chemical formula KAl2 (AlSi3O10) (OH) 2, with continuous layered silicon oxygen tetrahedron structure, with a very complete cleavage can be stripped, slice of flexible, soft flexible, transparent and colorless, thick piece of translucent with grey and brown and green, red roses, with glass to silk silk or pearl gloss, hardness of 2.5~3, the proportion of 2.75~3.0, acid resistance.
The chemical composition of Muscovite: KAl2[Si3AlO10] (OH, F) 2, the ideal component is eight body surface, containing Al, also can be a small amount of Fe3+, Mg, Fe2+, and even Mn, Cr, V and other replacement. Muscovite has a high degree of complete cleavage and pale white color. The characteristics of sheet elasticity.
Muscovite powder is widely used in building materials industry, fire industry, fire extinguishing agent, welding rod, plastics, electrical insulation, paper making, asphalt paper, rubber, pearlescent pigment and other chemical industry. Superfine mica powder can be used as functional fillers such as plastics, coatings, paints and rubber to improve its mechanical strength, toughness, adhesion, aging resistance and corrosion resistance. In addition, corrosion, elasticity, toughness and sliding resistance and noise, low coefficient of thermal expansion properties such as high electrical insulation, and launched the first two characteristics of sheet surface smooth, diameter thickness ratio, regular shape, strong adhesion.
