Refractory ceramic fiber blanket for boiler and power plant thermal insulation blanket spot wholesale

  The different manufacturing process of aluminum silicate needle punched blanket leads to its different uses, but its performance is basically the same
It has low thermal conductivity, good thermal insulation effect and low heat capacity, which can improve the utilization rate of heat energy, light weight, strong seismic resistance, good extensibility and excellent thermal insulation performance
Aluminum silicate needled blanket integrates fire resistance, heat insulation and heat preservation, and it has strong chemical stability and does not contain any binder
Ceramic fiber blanket has thermal conductivity close to air, which is due to the mixed planning of ceramic fiber blanket composed of solid fiber and air
The porosity is more than 90%
Many low thermal conductivity air is filled with pores, which destroys the continuous network planning of solid molecules, and then obtains excellent thermal insulation function
And the smaller the pore diameter and the more the number of pores cut by solid fiber in the direction of heat flow, the better the thermal insulation function of ceramic fiber blanket

The main factors affecting the thermal conductivity of ceramic fiber blanket include the following aspects: temperature, density, slag ball, fiber diameter, fiber humidity, application atmosphere and fiber direction
Because ceramic fiber blanket is different from traditional refractory brick, the planning and then selection of thermal insulation brick, and its heat conduction process is also different

 
The heat transfer in ceramic fiber blanket is not only the heat conduction of solid fiber, but also the heat conduction of air, the convective heat transfer of gas in open space and the radiation heat transfer between hole walls

 
Ceramic fiber blanket is used to replace the traditional heavy refractory as the lining material of industrial furnace wall, which can effectively strengthen the thermal insulation structure of industrial furnace, effectively control the heat loss of furnace body and realize the effect of energy saving

 
 
The operation cycle of the furnace is light, and the operation rate of various ceramic lining materials can be improved after the furnace wall is light

In the description of using aluminum silicate fiber needle punched blanket:
During initial use, when the component temperature exceeds 200 ℃, the aluminum silicate products will appear light smoke, which is the volatilization of aluminum silicate binder
The aluminum silicate products will turn brown in a short time
After 1-3 days of operation, the aluminum silicate will naturally return to the original white, and will not have any impact on the product quality
