Aluminum silicate fiber module industrial furnace thermal insulation materials and refractories

  The furnace top insulation construction environment is complex, which requires both good insulation effect and certain sealing effect
The insulation effect requires that the material should be light and the porosity should be large, so as to ensure low thermal conductivity, large thermal resistance and good insulation effect; The sealing effect requires that the density and bulk density of the material are large
Ceramic fiber module and refractory fiber coating can solve this contradiction
Aluminum silicate fiber module is a refractory material composed of alumina (Al2O3) and silica (SiO2)
The higher the oxide content is, the impurity is 44%, the total oxide content of standard aluminum silicate fiber module is 97%, the alumina content is 46%, the total oxide content of high-purity aluminum silicate fiber module is 99%, the alumina content is more than 47%, the alumina content is 49%, and the alumina content of high aluminum aluminum silicate fiber module is more than 52%
The zirconia content in the zirconia aluminum silicate fiber module is more than 15%
The higher the oxide content, the higher the heat resistance, and the price is directly proportional to it

The industrial furnace adopts aluminum silicate fiber material, which can effectively reduce the heat dissipation of furnace wall and improve the working efficiency of industrial furnace
Because of its excellent chemical properties, aluminum silicate fiber cotton can be used as refractory and lining of high-temperature insulation equipment

Jinshi aluminum silicate fiber module is made of aluminum silicate needle punched blanket made of burnt gemstone and quartzite after high-temperature melting, which is folded and compressed by wire throwing and needle punching
It has low thermal conductivity, strong tensile strength and tensile strength required by the national standard ≥ 30KPa, the fiber blanket produced by our company has high tensile strength, obvious strength advantage, good construction performance and strong wind erosion resistance
The slag ball content is low
The national standard requires that the slag ball with particle size greater than 0
212 is less than 20%
The slag ball content of Jinshi company is controlled
