High -quality refractory material aluminosilicate fiber
Aluminosilicate refractory fiber is also called ceramic fiber, and its main components are SIO2, Al2O3, Fe2O3, K2O, Na2o and T.D., of which SIO2 and AL2O3 make up more 95%, Fe2O3 is about 0,98%, and K2O and Na2O are about 0,5%.
The introduction of ceramic fiber
The surface of the ceramic fiber is smooth, and the inner solid phase exists in the form of a solid frame. Air with low thermal conductivity in the gap provides the effect of heat conservation. The method of production of aluminosilicate refractory material is to melt the selected burned raw materials for precious stones in an electric furnace at a temperature above 2000 ℃, and then by blowing or centrifugation to give it fibrousness.
Three types of aluminosilicate refractory fibers

Products, aluminum, Turn on blankets made of aluminosilicate fiber, Fibrous paper, fibrous rope, etc.. Studies of aluminosilicate have led to excellent results, and the temperature of thermal resistance was also increased from 1300 ° C to 1800 ° C and even higher. Besides, Fire -guided fibrous paper, prepared using ceramic fiber as raw materials, Combine with binders, stabilizers, etc.. can be used as heat -insulating materials and buffer materials in high temperatures, and can also be made in the form of tubular insulating materials and various insulating materials of a special form, cast insulating risers and other materials. The use of paper from ceramic fiber as a thermal insulation layer of aerospace apparatus is one of the most advanced studies at present.
