Aluminum silicate fiber blanket for thermal insulation of coke oven doo

  Aluminum silicate fiber blanket has white color, smooth and dense surface and is durable
As a new type of insulation furnace lining material, aluminum silicate fiber blanket has a wide range of applications, excellent performance and high tensile strength
Because the fiber blanket elongates the aluminum silicate fiber through the wire throwing process, which increases the toughness of the fiber itself and effectively resists the thermal impact in the furnace
The tensile strength required by the national standard is greater than or equal to 30KPa
The tensile strength of the fiber blanket produced by Jinshi is 80-120kpa, It has obvious strength advantages and good construction performance; The thermal conductivity is low, because the length and diameter of aluminum silicate fiber are very small, which greatly reduces the heat transfer area and improves the thermal resistance; Good thermal stability, because the chemical properties of aluminum silicate fiber are stable, rapid heating and cooling will not damage the fiber, protect the furnace body and prolong the service life; The weight of aluminum silicate fiber blanket is light, because the bulk density of aluminum silicate fiber module is generally 220kg / m3, and the unit weight of fiber blanket is 96kg / m3 or 128kg / m3
Special density can also be customized according to needs
Aluminum silicate fiber blanket has many characteristics, but different kilns have different working temperatures
Manufacturers need to combine the characteristics of fiber blanket to produce aluminum silicate fiber blanket suitable for different kilns and thermal equipment
At present, the fiber blanket below 1050 ℃ is suitable for boilers and kilns with low temperature requirements; The ceramic fiber blanket with temperature resistance of 1260 ℃ is the standard type, which is widely used by kiln manufacturers; High purity aluminum silicate fiber blanket is white in color and is used for lining insulation below 1260 ℃; High aluminum type is a product with high aluminum content in fiber products (aluminum in a certain range)
The higher the content, the higher the temperature resistance; The temperature resistance of zirconium containing aluminum silicate fiber blanket is about 1430 ℃, which is relatively high among the above types
Reasonable selection of aluminum silicate fiber blanket insulation materials is also a manifestation of energy conservation, emission reduction and environmental protection
You can choose appropriate insulation materials according to the specific furnace temperature
You can consult professional manufacturers to get twice the result with half the effort
