Model No.: Insulation gasket 50mmx12mmx0.35mm
High-performance insulation material that has been following the spacecraft into space ------ Fluorite mica flakes
The fluorite crystal mica texture is very pure, and it does not contain OH-(hydroxyl). Its chemical formula is KMg3(AlSi3O10)F2(OH)-. Fluorine replaces the hydroxyl group. Electrical performance is also very good. The volume resistivity is 1015~1016Ω•cm (approximately 1000 times higher than that of natural mica); the electric breakdown strength is 185~238kv/mm, which is 10 times that of PTFE; and the safe use temperature can reach 1100°C. . Its melting and crystallization temperature is 1375°C.
The fluorocrystal mica has a very good thermal shock stability. The five labs of Saibao Laboratories, Guangzhou, Ministry of Information Industry, conducted 10 cycle tests at -40°C to 70°C, all of which were qualified.
Natural mica is an underground natural ore that contains many impurities and contains OH-(hydroxyl). Its ideal chemical formula is KAI2(AISi3O10)(OH)2 and KMg3(AISi3O10)(OH)2, with unstable electrical properties. The electrical properties at high temperature and high frequency are even worse. When the temperature is above 500°C, the characteristics of mica are gradually lost due to dehydration. The commonly used insulating material PTFE, because of its poor temperature resistance, can only be used in low temperature environments, and its production is easy to have metal impurities, corona is not good. It can be seen that the electrical insulating properties of natural mica and PTFE are incomparable with that of fluorite mica. .
Fluorocrystalline mica has been selected by CEC Shijiazhuang No. 13 for national key aerospace projects - Shenzhou No. 8, No. 9, No. 10 ... spacecraft and various satellites as insulating spacers. Nine schools in Mianyang were also selected as electrical Insulation Materials. Fluorocrystalline mica is an ideal electrical insulation material for high-end technology.
Insulating materials commonly used in the general industry are natural mica and polytetrafluoroethylene. Natural mica is an underground ore naturally formed and belongs to silicates. Its ideal chemical formula is KAl2(AlSi3O10)(OH)2 and KMg3(AlSi3O10)(OH)2, containing (OH) deuterium (hydroxy). Due to the presence of hydroxyl (water molecules), its performance in all aspects is far lower than that of fluorophlogopite. Natural mica contains a lot of impurities, the electrical properties are unstable, and the electrical properties at high temperature and high frequency are even worse. When the temperature is above 500 DEG C, the characteristics of mica are gradually lost due to dehydration.
PTFE, because of its poor temperature resistance, can only be used in low temperature environments (generally not more than 300 °C), and its production is easy to have metal impurities, corona is not good.
It can be seen that the electrical insulating properties of natural mica and PTFE are incomparable with that of fluorite mica.
Fluorocrystalline mica is an ideal electrical insulation material for high-end technology. It has been nearly 10 years since 2005 when it was selected for the aerospace equipment as an Insulation Gasket by the 13th research group of Shijiazhuang of the China Power Group. In the past ten years, the 13th Institute has applied fluorocrystal mica to all space equipment including the spacecraft No.8, No.9 and No.10 of China, and environmental monitoring satellites (pointer No.9) as insulating films.
Changchun Taiyuan fluoromica Co. Ltd. is located in Changchun high tech Industrial Development zone. It is a high-tech economic entity integrating scientific research, production and management. The company has a strong technical team. There are 1 senior experts and doctoral tutors who have been engaged in artificial lens research for more than 20 years, 1 postdoctoral researchers engaged in nonlinear control research, 1 researchers engaged in inorganic material research, and several senior engineers and engineers engaged in research of related specialties. Strong technical force has laid the foundation for the development of the company in the field of new materials.
To meet the needs of national industrial development, the company has been devoted to the research and development of fluorite mica and its products in 2004. The product is a new material with high temperature resistance, corrosion resistance, low dielectric loss, high volume resistivity, absorption of multi band beam and good transmittance of light. It is transparent, separable, elastic, aging and fragile. It is mainly used in the working environment of electric insulation, neutron test, high frequency medium, high temperature vacuum, high temperature and high pressure, strong acid and strong alkali. It can be used as a substitute for low performance materials such as polytetrafluoroethylene, natural mica and quartz glass.
Our company warmly welcome friends from all walks of life to visit, hope you know the fluorite mica and the use of fluorite mica. Our company will provide free test supplies for scientific research personnel in the high-tech field. Taiyuan company spirit of "harmony, modesty, pragmat.
