Product Description

Introduction of Mica Powder

Mica is stratiform mineral ,Its composed of potassium (K), aluminum (AI),magnesium (Mg),Iron(Fe) and lithium(Li).There are different categories of mica, including white mica, phlogopite, biotite and lepidolite (Lithia mica) . white mica is widely used in industry and national defense because it is elasticity, tenacity and insulativity. it is also acid and alkali resistant, and corrosionproof, which can be stripped, with low coefficient of expansion etc.

Mica powder is widely used as a raw material in mica ceramics, a filler in plastic, rubber, building materials, and paints, as a protective layer on welding rods, as an additive in drilling mud, and also in coatings, paints, fire safety products, linoleum, paper, oil drilling products, and cosmetics.
 

1. Acts as a sealant when used as a drilling mud additive.
2. In building surface materials, it protects against rain, insulates against the heat or cold, and provides decorative effects.
3. A coating of mica powder mixed with mineral wool and resin can provide a decorative layer on concrete, stone, and masonry outer walls.
4. Used in the protective layers on welding rods, wires, and cables.
5. Used as a filler in linoleum, pipe mortar, and adhesive. It can be used to make decorative coatings and sound-a sorting plaster. Used as a filler in ceiling panels and concrete and cement mortar; increases the strength of cement mortar.
6. When used as a filler in rubber products, mica acts as a lubricant and provides electrical insulation, heat resistance, and acid/alkali resistance. It serves as a covering agent in tire reconditioning, and can provide lubrication between tire and inner tube. Increases mechanical strength, toughness, adhesion, and anti-aging and anti-corrosion properties when used in rubber and plastic.
7. When used in paint, mica can increase reflectivity and heat resistance, reduce damage from UV radiation, light, and heat, boost resistance to acids and alkalis, increase electrical insulation, and provide a bright and attractive paint layer. It can also enhance their ability, corrosion resistance, toughness, and tightness, reduce air permeability, and prevent spotting and crazing. It increases resistance to oil and water, and prevents pigments from settling. It is an important filler in anti-corrosion coatings. It is used in the coating applied to the model when casting metal, and is also used in coatings for electroplating tanks. It helps remove oil when used as a filler in cosmetics. It is an additive in anti-freezing and anti-sun paints, and is mixed with sealing paint-on plaster. It is used in the powder in dry fire extinguishers.

Mica can dramatically enhance the durability of paint and coatings. It increases water resistance, enhances adhesion between the paint and the substrate, boosts paint strength, and improves appearance.
