Mica piece size : 10mesh,16-40mesh
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 corrosion roof, which can be stripped, with low coefficient of expansion etc.
The chemical equation: KAI2 (Si3AIO10)(OH.F)2

Application:
Mica powder can be used in paint and coating to reduce the damage of ultraviolet rays or other Light and heat damage to the paint film, promote coating acid and alkali. and insulation, and to t= strengthen its durability , freezing resistance corrosion resistance, water resistance etc. it helps to strengthen the adherence to the layer, improve its intensity, brightness, tenacity and Compaction. As a result ,it is conducive to reduce the ventilation ,to prevent speckle and chaps as well as reduce sediment in the paint. As a prior filler in paint, mica powder can be used to substitute some expensive raw materials in the paint so as to reduce the production cost.
Mica powder is also the basic raw material for mica ceramics products.
Mica powder can be applied in protecting layer of welding rods, conducting wires and electric cables.
It can be use as suspended substance in fire-fighting dry powder.
It can be taken as a filler, a shelter, a lubricating substance, a drawing of patterns in plastics, rubber, asbestos products and sealing materials.
It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid and alkali products.
It can be used as coating in models of Cast metal, the brightening material in aluminum and paint in Plating bath.
- Q: The fire prevention board line is made of what material?
- The line is a kind of composite stainless steel decorative profiles which outer layer is the matte frosted stainless steel plate and inner liningl is wooden material. It do not need to render with fine wood and also need not to buy a stainless steel plate cutting, cutting, bending, such as multi-channel intricate process, processing production. It is convenient to install through the buckle button directly on the booth. When installation, it only needs to be bolt and plug to be fixed on the wallafter blanking cut. compared with the traditional wooden play crural line, the profile is more beautiful and firm, and environmental friendly. And compared with the traditional craft production of stainless steel line, it's cheaper and more convenient to install. This product is not only sitable to decorate in the family, but also is more suitable for the hotel, hotel, office building, and the application of all kinds of public places.
- Q: For refractory, what is critical particle size? Thank you.
- 0
- Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
- Refractory concrete generally divided into three categories: lightweight concrete (used in insulation); refractory concrete (for refractory temperature requirements are not very high position, and can withstand a certain air scour); heavy refractory concrete (flow with higher requirements for refractory temperature parts, and can withstand a certain intensity). Mainly depends on the design temperature and the use of parts.
- Q: What things and cement mixed can act as refractory?
- Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.
- Q: what is the common materials for home fireproofing material?
- 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
- Q: What are the characteristics of clay refractory materials?
- Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.
- Q: Is there anyone who can explain how to grade the level of fire insulation board?
- 1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
- Q: What are the uses of refractory materials of glass furnace?
- crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......
