Jiuqiang Ceramic Fibre Board are made from Jiuqiang refractory ceramic fiber, attending inorganic and suitable organic binders. The mixture is vacuum processed into boards or formed shapes that keep good mechanical strength after heating. These products can be manufactured using four basic fiber types: Sinoshine Board, classification temperature 1000,1150, 1260, 1400.
Jiuqiang Ceramic Fibre Board family exhibits excellent chemical stability, resisting attack by most corrosive agents. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulfuric acids as well as concentrated alkalies. Sinoshine Ceramic Fibre Board also resist oxidation and reduction. If wet by water, steam or oil, thermal and physical properties are completely restored upon drying.
Characteristics of ceramic fiber board
1)Smooth surface
2)Low impurity, and average bulk density and thickness
3)Excellent mechanical strength and structural strength
4)Low thermal conductivity
5)Low shrinkage
6)Resistant airspeed eroding
Application of ceramic fiber board
Back-up lining of high-temperature industry furnaces
Hot-face lining of ceramic kilns,heat-treatment furnaces and other industrial kilnsInsulation for furnace door and kiln car
