Factory Supply of Mica Powder / Particle / Lamellar for Drilling
Mica is a layered hydrous aluminum silicate mineral containing potassium, aluminum, magnesium, iron, lithium and other elements, common are: Muscovite, phlogopite, biotite, lipolite, sericite five subgroups, because Muscovite has excellent elasticity, toughness, insulation, high temperature resistance, acid and alkali resistance, corrosion resistance can be peeled, thermal expansion coefficient is small, and other properties. "Zhongyu Mining" in Lingshou County to the present the most advanced dewatering, stripping, grading and screening equipment to develop and produce a smooth surface, larger diameter to thickness ratio, regular form, stronger adhesion, better sliding and other advantages.
Chemical composition | SiO2 | A12o3 | K2o | Na2O | MgO | Fe2O3 | TiO2 | S+P | Cao | H2O |
Content | 44-50 | 20-30 | 9-11 | 0.16-1.8 | 0.32-2 | 2-6 | 0.7-1.2 | 0.02-0.05 | 0.02-0.77 | 2.62 |
The use of mica powder in paints and coatings can reduce the damage of ultraviolet light or other light and heat to the paint film, increase the acid and alkali resistance and electrical insulation properties of the coating, improve the durability of the coating, freeze resistance, corrosion resistance, water permeability resistance, enhance the adhesion between the coating and the substrate, improve the strength of the coating, brightness, toughness and compactness, reduce the permeability of the coating, prevent spots and cracks, and improve the quality of the coating. It can also prevent paint precipitation, mica powder can replace some expensive raw materials in the paint, which can reduce costs, and is the preferred filler for paint and anti-corrosion coatings.
Mica powder is the basic raw material for the production of mica ceramic products. Mica powder can be used as a filler for oilfield drilling mud and plays a sealing role. Mica powder can be used as a protective coating for welding rods, wires and cables. Mica powder can be used as a suspended agent for fire fighting dry powder. Fillers for cosmetic defat powder, fillers for high-strength electrical insulation and heat-resistant, acid-alkali resistant products, etc., coatings for casting metal models, polishing agents for aluminum products, plating bath coatings, etc.
