Introduction and use of mica
Mica (rock-forming mineral)
Mica is a rock-forming mineral, showing hexagonal flake crystal shape, is one of the main rock-forming minerals. Characterized by insulation, high temperature resistance, the most used in industry is sericite mica, which is widely used in paint, lacquer, electric insulation and other industries.
Main Uses
Industrial use
Black mica is mainly utilized in industry for its insulating and heat-resistant properties, as well as its resistance to acid, alkali, pressure and stripping, and is used as an insulating material for electrical equipment and electrical appliances; and secondly, it is used in the manufacture of windows of steam boilers, smelting furnaces and parts of machinery. Crushed mica and mica powder can be processed into mica paper, which can also be used to replace mica sheets to make various kinds of low-cost, uniform thickness insulating materials.
The main application is white mica, followed by gold mica, which is the most used in industry. It is widely used in building materials industry, fire-fighting industry, fire extinguishing agent, welding rod, plastics, electric insulation, paper making, asphalt paper, rubber, pearlescent pigment and other chemical industries. Ultrafine mica powder for plastics, coatings, paints, rubber and other functional fillers, can improve its mechanical strength, enhance the toughness, adhesion anti-aging and corrosion resistance type. In addition to the very high electrical insulation, acid and alkali corrosion resistance, elasticity, toughness and sliding, heat and sound insulation, small coefficient of thermal expansion and other properties, and take the lead in the launch of the flake two smooth surface, diameter-thickness ratio of the form of regular, strong adhesion and other characteristics.
Medicinal use
Mica, sweet flavor, flat nature. Injured by wind and cold fever, as the body sits on a boat, dizziness, with the ability to lay away the wind, enrich the five organs, increase fertility, make the eyes bright, long service body light and dexterous, prolong life. It is also known as Yunzhu, Yunhua, Yunying, Yunliquid, Yunsand, and Phosphorus Stone, and is produced deep in the mountains.
