High-quality Refractory Material Aluminum Silicate Fiber

Aluminum silicate refractory fiber is also called ceramic fiber, and its main components are SiO2, Al2O3, Fe2O3, K2O, Na2O, etc., of which SiO2 and Al2O3 account for more than 95%, Fe2O3 accounts for about 0.98%, and K2O and Na2O account for about 0.5%.

Ceramic fiber introduction

The surface of the Ceramic fiber is smooth, and the internal solid phase exists in the form of a continuous skeleton. With the low thermal conductivity air in the gap, it has the effect of heat preservation. The production method of aluminum silicate refractory material is to melt the selected burnt gem raw material in an electric furnace above 2000 ℃, and then use blowing or centrifugation to make it fibrous.

Three types of aluminum silicate refractory fibers

Aluminum silicate fiber-related products

Products related to aluminum silicate include aluminum silicate fiber blankets, fiber paper, fiber rope, etc. The research on aluminum silicate has achieved great results, and the high-temperature resistance temperature has also been increased from 1300°C to 1800°C, and even higher. I tua atu, the refractory fiber paper prepared with ceramic fiber as raw material, combined with binders, stabilizers, etc. can be used as heat insulation materials and buffer materials in high-temperature environments, and can also be made into tubular and various special-shaped insulation materials and Cast insulation riser and other materials. The application of ceramic fiber paper to the heat insulation layer of aerospace vehicles is one of the most cutting-edge research at present.
