High Alumina Type Ceramic Fiber Blanket
The Description:
Alumina content above 58%, Al2O3 and SiO2 greater than 98.5%) high purity amorphous fiber thermal refractory materials. In 1970, Japan began to produce Al2O3 60% high aluminum refractory fiber, which was rapidly developed in the late 1970s. Due to the production of Al2O3 more than 58% of high aluminum fiber, fiber formation is more difficult, easy to cause high slag ball content, so many countries in the world have changed to the production of Al2O3 about 55% amorphous refractory fiber. China began to produce high-aluminum fiber in 1981, which stipulated that the Al2O3 content of high-aluminum fiber should be greater than 58%, and the actual Al2O3 fluctuated between 58% and 61%.

The Feature:
The effect of ceramic fiber blanket is to cut off heat and save energy, and can play the role of fire and heat insulation. Applicable to high temperature environment packing seal and insulation (kiln car, pipe, kiln door, etc.), as well as a variety of industrial furnace lining (hot surface, backing) components/veneer block production of building fire prevention, as sound absorption or high temperature filtration materials and other materials, belong to light refractory materials.
