Refractories can be seen everywhere around the outside. With the development of science and technology, many products are gradually added to our lives. Today, Xiaobian will tell you some common refractories.
Aluminum silicate: alsio3, made from hard clay clinker by resistance or electric arc furnace melting and blowing into fiber process. Aluminum silicate fiber, also known as ceramic fiber, is a new type of light refractory material. The material has the advantages of light volume weight, high temperature resistance, good thermal stability, low heat conductivity, small heat capacity, good mechanical vibration resistance, small thermal expansion, good heat insulation performance, etc. after special processing, it can be made into aluminum silicate fiber board, aluminum silicate fiber felt, aluminum silicate fiber rope, aluminum silicate fiber blanket and other products. The new sealing material has the characteristics of low thermal conductivity, light volume weight, long service life, high tensile strength, good elasticity, non-toxic and so on. It is a new type of material replacing asbestos and widely used in thermal energy equipment of metallurgy, electric power, machinery and chemical industry.
Ceramic fiber is also called aluminum silicate fiber, because one of its main components is alumina, and alumina is the main component of porcelain, so it is called ceramic fiber. Adding zirconia or chromium oxide can further improve the service temperature of ceramic fiber. Ceramic fiber products refer to the industrial products with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance, which are made of ceramic fiber as raw materials. They are specially used in various environments with high temperature, high pressure and easy wear. Ceramic fiber products are excellent refractories. The utility model has the advantages of light weight, high temperature resistance, small heat capacity, good heat preservation and insulation performance, good high temperature insulation performance, non toxicity, etc.
Rock wool originated in Hawaii. As an inorganic material, rock wool is introduced by China Shida rock wool manufacturing Co., Ltd. --- as one of the large rock wool production enterprises in China, specializing in the production of Shida series of high-end rock wool products. Rock wool is made of high-quality basalt, dolomite and other raw materials. After high-temperature melting, the artificial inorganic fiber made by high-speed centrifugal equipment has very strong heat preservation and fire protection performance.
Glass wool belongs to a category of glass fiber, which is a kind of artificial inorganic fiber. Glass wool is a kind of material which can make the fused glass fiber to form cotton like material. Its chemical composition belongs to glass and it is a kind of inorganic fiber. It has good molding, small volume density, thermal conductivity, thermal insulation, sound absorption, corrosion resistance and chemical stability. It has a large number of tiny air pores, which make it play the role of heat insulation, sound absorption, noise reduction and safety protection. It is a good material for heat insulation, sound absorption and noise reduction of steel structure buildings.
Do you have a certain understanding of refractories after reading this article? I hope it can help you.
