aluminum silicate fiberIs a new type of lightweight energy-saving refractory material, it is based on flint clay as the main raw material, by 2100 degrees high temperature melting, high-speed centrifugal or injection processing of a cotton filamentous inorganic fiber. The main chemical composition of aluminum silicate fiber is silicon dioxide(48~52%)Aluminum oxide(43~49%), ferric oxide(0.9~0.13%)Calcium oxide(Less1%)and magnesium oxide(trace). Aluminum silicate fiber has the advantages of high temperature resistance, good thermal stability, low thermal conductivity, small thermal capacity, good mechanical vibration resistance, small thermal expansion, and good thermal insulation performance. It can be made into aluminum silicate fiber board, aluminum silicate fiber felt, aluminum silicate fiber rope, aluminum silicate fiber blanket and other products by weaving or weaving. It is a new material to replace asbestos and is widely used in metallurgy, electric power, machinery, chemical industry, etc. Insulation of thermal equipment in the industry.

Aluminum silicate fiber performance and stability: excellent heat insulation, acid and alkali resistance, excellent chemical stability, good electrical insulation and sound absorption, can absorb more than 80%500HzThe above medium and high waves; it has excellent heat insulation, good acid and alkali resistance, good electrical insulation and sound absorption, and can absorb80%Above500HzAbove the medium-high wave.

aluminum silicate fiberSynthesis method: 1, the use of melting method. Kaolin, alumina and silica are mixed in a certain proportion and placed in an electric arc furnace or electric resistance furnace.2000The melt is discharged from the furnace in the form of a thin stream and is blown onto the melt by a high-speed air stream to form fibrosis.2The melting method is adopted. Aluminum silicate fiber is a combination of kaolin, alumina and silica.Al2O3/SiO2(mass ratio)11The ratio of mixing, in an electric arc furnace or resistance furnace.2000The above high-temperature melting, the melt flows out of the furnace in the form of fine flow, and is blown onto the melt with high-speed air flow to form fibrosis. According to the silica and alumina content of the product, secondary processing is carried out to obtain the product.

Aluminum silicate fiber use: aluminum silicate fiber is a kind of high temperature resistant fiber, with light bulk density, high temperature resistance, good thermal stability, low thermal conductivity, mechanical vibration resistance, elasticity, sound insulation, electrical insulation, good chemical stability and other characteristics, can be used in metallurgy, chemical industry, electric power, machinery and other industries such as melting furnace high temperature equipment. As a high-temperature furnace filler, furnace insulation layer and heating pipe insulation, etc., it can also be used as a high-temperature sealing, filtration, noise reduction, catalyst carrier and composite reinforcement materials.

Duealuminum silicate fiberThe production cost is high. At present, the application of aluminum silicate refractory fiber and its products is mainly concentrated in the field of industrial production, but not much in the field of construction. It is mainly used for the lining and heat insulation materials of various industrial furnaces that use coal, oil, gas, and electricity as energy sources. It can also be used as heat-resistant reinforcement materials and high-temperature filter materials. As the lining material, it can be used for thermal insulation lining of atomic energy reactors, industrial furnaces, metallurgical furnaces, petrochemical reaction devices, as well as thermal insulation lining of metal material heat treatment furnaces, ceramic firing furnaces, etc.
