Introduction of mica powder

Mica is characterized by high insulation strength and resistance, low dielectric loss, arc resistance, corona resistance and other excellent dielectric properties, high temperature resistance and rapid temperature change, as well as insulation, heat resistance, acid and alkali resistance, compression resistance and peeling resistance Moreover, it has the characteristics of hard texture, high mechanical strength, luster, stable physical and chemical properties, good heat insulation, elasticity and toughness, heat and sound insulation, small thermal expansion coefficient, etc., as well as bright surface, large diameter thickness ratio, regular shape and strong adhesion After processing, mica powder has better sliding property and strong adhesion Mica and mica powder are widely used in radio industry, aviation industry and motor manufacturing due to their own properties They are also widely used in coating, paint, plastic, linoleum, papermaking, oil field drilling, decoration and makeup industries In the paint, they can reduce the damage of ultraviolet or other light and heat to the paint film and increase the Acid resistance, alkali resistance and electrical insulation performance, improve the frost resistance, corrosion resistance, toughness and compactness of the coating, reduce the permeability of the coating, and prevent spots and cracks Mica powder can also be used in roof materials, such as rain proof, heat insulation, etc mica powder and mineral wool resin paint are mixed, which can be used for decoration of concrete, stone, brick external walls Mica powder can be used for linoleum, pipeline mortar, cementitious agent; in rubber products, mica powder can be used as lubricating agent, film remover, and filler for high-strength electrical insulation, heat-resistant, acid and alkali resistant products Mica can also be used as mica paper, mica board, mica ceramics, Pearlescent Mica Pigment, mica casting products, etc It is widely used in mica ceramic raw materials, plastic and rubber additives, building materials, paint additives, protective layer of welding electrode coating, drilling mud additives, coatings, paints, fire fighting, oil consumption paper making, oil well drilling, decoration and makeup industries 1 Oil well drilling mud additive plays the role of sealant 2 In the roofing materials, it plays the role of rain proof, heat insulation and decoration 3 Mica powder is used for mineral wool resin and paint mixing, and can be used as decorative coating of concrete, stone and brick through the outer wall 4 Mica powder is used for protective coating of electrodes, wires and cables 5 Mica powder is used as filler for oil consumption, pipeline mortar and cementitious agent, making decorative coating and sound absorption putty; filler for ceiling and concrete and filler for cement mortar, so as to improve the strength of cement mortar 6 In rubber products, it is used as lubricant and filler of high-strength electrical insulation and heat-resistant, acid and alkali resistant products, as covering agent in tire retreading, and as lubricant between inner and outer tires in tire manufacturing In the use of rubber plastics, it can improve its mechanical strength, enhance toughness, adhesion, anti-aging and corrosion resistance Seven When used in paint, it can reflect light and heat, reduce the damage of ultraviolet and other light and heat to paint film, increase the acid, alkali and electrical insulation performance of the coating, make the coating bright and beautiful, improve the durability, frost resistance, corrosion resistance, toughness and compactness of the coating, reduce the permeability of the coating, prevent spots and cracks, improve the resistance to oil and water erosion, and prevent paint precipitation It is also the first choice of fillers for important anticorrosive coatings The coating used as model when pouring metal, the coating used for electroplating solution tank, the filler used for degreasing powder in cosmetics, the additive used for anti freezing and anti Yang paint paste, the admixture used for sealing paint ash, the powder suspension used for dry powder fire extinguisher, etc 8 In the coating, it can greatly improve the weather resistance, water resistance, adhesion between the coating and the substrate and the strength of the coating, and improve the appearance of the coating
