Refractory Ceramic Fiber Blanket for Insulation
Specifications
Ceramic fiber blanket is manufactured from aluminum silicate fiber bulk spinning from kaolinite, alumina silicCeramic fiber blanket descriptions:
1.Refractory Ceramic Fiber Blanket for thermal Insulationblanket
Refractory Ceramic Fiber Blanket is made through intensive needle-punching processing . The product does not contain any bond or other compositions,and also no slag inclusion content. The intensive needle-punching technics improved the fiber intertexture and the resistance performance against delamination as well as the tensile strength.It have a good high temperature shrinkage after the heat treatment of 750-950 during the producing. Beside the charicteriatics in common,it have better sound insulation performance and mechanism strength,is easy to machining and install.
2. Ceramic fiber blanket Product Features :
Low thermal conductivity ,heat storage and heat capacity
Excellent heat insulation
Excellent chemical stability
Shock and chemical attack resistant
Low thermal conductivity and shrinkage
Resilience under working condition, Low shrinkage under high temperature.
Excellent sound insulation and resistance of folding
