The Ceramic Fiber Needle-punching 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.
Ceramic fiber blanket application:
Industrial furnace,Heat treatment,High temperature pipe
Insulating materials of boiler, turbine and nuclear power
Insulating material for face and top of industrial furnaces and heating device
Excellent sound insulation for Construction Fire protection
High temperature filter material for nonferrous metal.
