The scope of application of general mica board and high temperature resistant mica board is different. High temperature resistant mica sheets are widely used in building material industry, fire fighting industry, fire extinguishing agent, welding rod, plastic, electrical insulation, paper, asphalt paper, rubber, pearlescent pigment and other chemical industries.
Superfine mica powder can be used as a functional filler for plastics, coatings, paints, rubber, etc. It improves mechanical strength, enhances wear resistance, adhesion, aging resistance and corrosion resistance. In addition to the functions of high electrical insulation, acid and alkali corrosion resistance, elasticity, anti-slip, heat and sound insulation, and small coefficient of thermal expansion, it also has the characteristics of double-sided lubrication, large diameter-thickness ratio, regular shape, and strong adhesion.
800℃ high temperature resistant mica board silica gel, packed in 200kg iron drum, sealed and stored in 30℃ ventilated dry and cool place, away from direct sunlight and heat source, stored for more than six months, transported as dangerous goods.
In industry, its insulation and heat resistance function, as well as acid resistance, alkali resistance, pressure resistance and peeling function are mainly used as insulation materials for electrical equipment and electrical equipment; secondly, it is used to make the windows of steam boilers and mechanical parts melting furnaces. Mica flakes and mica powder can be processed into mica paper, and also can replace mica flakes to make low-cost and uniform thickness insulating materials.
White mica type: HP-5, made of 501 mica paper and silicone adhesive, subject to thermal constraints. The mica content is about 90% and the silicone rubber content is 10%. High temperature resistant mica sheet, type: hp-8, made of 503 mica sheet bonded with silicone adhesive. The mica content is 90% and the silicone rubber content is 10% after heat constraint. Because of the different mica paper used, the function is also different.
Generally HP-5 mica board can withstand 600-800 degree high temperature, HP-8 high temperature resistant mica board can withstand 800-1000 degree high temperature. After hot pressing for one day and one night, it has high flexural strength and excellent bending resistance. It can process various shapes without delamination and other advantages.
