Mica is a layered hydrous aluminosilicate mineral containing potassium, aluminum, lithium and other elements, and is an important non-metallic mineral. Mica mineral uses are mainly in the electrical industry, electrical industry, defense and military communications, as well as insulators for home appliances and electric furnaces.
The most commonly used in industry are muscovite and phlogopite. Muscovite has high electrical insulation and low dielectric loss tangent, as well as electrical properties such as arc resistance and corona resistance, and has physical and chemical properties such as high mechanical strength, high temperature resistance, and corrosion resistance. Elastic transparent sheet. The electrical properties of phlogopite are inferior to that of muscovite, but it has better heat resistance and is a good heat-resistant insulating material.
According to the use, mica can be classified into sheet mica, crushed mica and mica powder.
Sheet mica is mainly used in the electrical industry, electrical industry, defense and military communications, as well as insulators for home appliances and electric furnaces.
Crushed mica is generally used to grind mica powder, or to make mica paper, heat-resistant mica board, and to produce expanded mica, insulating bricks, tiles, boards and other building materials.
Mica powder is used to make mica glass, mica ceramics, etc. Mica powder with different particle sizes has different uses. For example, 1-5μm mica powder is used as filler and filler in paints and plastics, and as dusting agent in rubber wheels; smaller than 0.043mm Mica powder is widely used in industrial sectors such as paint, rubber, plastics and pearlescent pigments; mica powder of 0.097-0.043mm is used as special pigment filler, lubricant for rubber products and mold release device; mica of 0.246-0.147mm Powder generally produces mica ceramics and other raw materials.
The production of mica powder has two processes: dry method and wet method. Hongcheng HCH series ultra-fine ring roller mill and HLMX series ultra-fine vertical mill are the most energy-saving and environmentally friendly advanced dry ultra-fine grinding equipment in China. Compared with jet mill and ball mill, HCH series ultra-fine ring roller mill and HLMX series ultra-fine vertical mill are more energy-saving and environmentally friendly, and users can freely choose the equipment model with corresponding processing capacity according to the processing capacity.
