polycrystalline mullite fiberThe application range of is very wide, we must know its basic definition before using it.?So you can apply it better. If you are interested in this topic, then take a look at it together, hoping to help some relevant people.

polycrystalline mullite fiberIt is widely used in various industries, so its use is certainly very extensive. In fact, polycrystalline mullite fiber is a polycrystalline alumina fiber. in fiberAl2O3content in72%-75%Between, usuallyAl2O3content in80%The above is called polycrystalline alumina fiber. In addition, its main crystal phase is single mullite phase, and its thermal stability is better when used in polycrystalline alumina fibers at high temperatures. In this case, its use temperature is higher1400C. In fact, the product we are talking about today is a new type of ultra-light high-temperature refractory fiber at home and abroad. It is the wholeAl2O3-SiO2One of the ceramic fibers. The use temperature is1500-1700℃, higher than glass fiber200-400C. Today we look at the production technology of polycrystalline mullite fiber. Company in1983Year3Completed the Zhejiang Provincial Science and Technology Commission "crystal fiber research" major scientific research project, is a domestic unit to obtain technical appraisal. Now, after years of hard work, they have superb production experience and reliable quality assurance, and provide a series of after-sales service measures for application technical consultation, installation and construction.

The polycrystalline mullite fiber on the market provides a material basis for the majority of designers and researchers to design new equipment, develop new products and new processes; for industrial and mining enterprises with thermal equipment, transforming old equipment, increasing production and saving energy, Naturally, it is a relatively ideal means to improve the environment, even if progress provides a relatively ideal means. Polycrystalline mullite fibers are composed of refractory metal oxide crystallites. With polycrystalline mullite fiber, it can naturally be used for a long time.1600Insulation materials for high-temperature thermal equipment below °C, such as silicon carbide electric furnaces, molybdenum silicide electric furnaces, various steel heating furnaces, mechanical forging furnaces, etc., can significantly improve the thermal efficiency of the equipment. Now it can greatly save energy, increase productivity and improve product quality. Of course, it can be seen in many places. For example, polycrystalline mullite fiber can be applied to the heat insulation of various high-temperature industrial kilns; ceramic kilns; mechanical and metallurgical heating furnaces; thermal lining of heat treatment furnaces and other industrial kilns; high-temperature fire barriers; thermal insulation materials such as kiln doors, kiln cars, expansion joints, etc.; glass kiln insulation.

The above article content is for the use of friends aboutpolycrystalline mullite fiberThe basic problems that need to be understood, and a better polycrystalline mullite fiber manufacturer that is also shared in the content, if you have this demand, you can check it out, hoping to help you.
