Mica Shield For Gauge Glass, For High Temp Up To 400 Deg C
Natural mica sheet is a kind of high temperature resistant insulating material, which can be used in 800℃ for a long time. Good mechanical properties, heat resistance and electrical insulation, large volume resistivity, good dielectric loss. It has the advantages of no layer, no crack and no deformation.
The mica sheet is composed of polysilicon Muscovite, quartz, garnet and rutile, with albitite, zoisite and chlorite. The garnet is rich in Fe and Mg, and the Si of polysilicon Muscovite is up to 3.369, which is also a high pressure combination.
There are more kinds of natural mica, and two kinds of white mica and gold mica are used as electrical insulation materials. Muscovite has glass luster, generally colorless transparent; Gold mica has metallic burnish and semi-metallic burnish, common have golden yellow, brown, shallow green and so on, diaphaneity is poorer. White mica and gold mica have good electrical and mechanical properties, good heat resistance, good chemical stability and corona resistance.
The most commonly used natural mica is flake. Generally, high-quality thick mica with a certain thickness and a certain shape is made by stripping, thickening, cutting and punching. Widely used in electron tube electric ferrochrome, capacitors, audio, electrical appliances, metallurgy, and other heating elements of high temperature insulation. Because it is a natural material, has no pollution, good insulation, voltage resistance characteristics, other products can’t replace the product.
According to the quality of the strip can be divided into class A, b, C, various grades according to the approximate area can be divided into no. 3 to no. 9, etc. The thickness of the commonly used sheet is: 0.05 0.07 0.10 0.15 0.20 0.25 0.30 0.35 0.40mm.
High-grade grade A piece is specially used for making: optical piece, fire watch piece, window piece, high temperature water level gauge piece, liquid level gauge piece, the surface appearance is pure, no impurities, no knife mark, no scratch, no bubble, no trachoma and other high purity mica products. Suitable for large power plants, boiler plants, metallurgy and other industries with high technical requirements.
