China Manufacturer Natural Mica /Dyed Mica/Synthetic Mica Flakes with 40-80mesh
Mica is the general name of mica group minerals. It is the aluminosilicate of potassium, aluminum, magnesium, iron, lithium and other metals, all of which are layered and monoclinic. The crystal is pseudohexagonal lamellae or plate like, occasionally columnar. The lamellar cleavage is very complete, with glass luster and elastic sheet. The refractive index of mica increases with the increase of iron content, from low protrusion to medium protrusion. The variety without iron is colorless in the flake. The higher the iron content, the darker the color, and the more polychromatic and absorptive.
Mica flake size: 6-10mesh, 10-20mesh,
Mica powder: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh and 5000mesh.
Application
In the industry, biotite mainly uses its insulation and heat resistance, as well as acid resistance, alkali resistance, compression resistance and peeling resistance, as the insulation material of electrical equipment and electrical equipment; secondly, it is used to manufacture the windows and mechanical parts of steam boilers and smelting furnaces. Mica chips and mica powder can be processed into mica paper, and can also replace mica sheet to produce various low-cost and uniform thickness insulating materials.
Muscovite is the most widely used in industry, followed by phlogopite. It is widely used in building materials industry, fire fighting industry, fire extinguishing agent, welding rod, plastic, electrical insulation, paper making, asphalt paper, rubber, pearlescent pigment and other chemical industries.
Ultrafine mica powder is used as functional filler for plastic, paint, paint, rubber and so on, which can improve its mechanical strength, enhance toughness, adhesion, anti-aging and corrosion resistance.
here are many types of natural mica used as electrical insulation materials
There are two types of mica: muscovite and phlogopite. White mica has a glassy luster and is generally colorless and transparent; Gold mica has metallic and semi metallic luster, with common ones being golden yellow, brown, light green, etc., but with poor transparency. White mica and phlogopite have good electrical and mechanical properties, good heat resistance, chemical stability, and corona resistance. Both types of mica can be peeled and processed into soft and elastic thin sheets with a thickness of 0.01 to 0.03 millimeters. The electrical performance of muscovite is better than that of phlogopite, but phlogopite is soft and has better heat resistance than muscovite.
