Refractory Ceramic Fibre Board
1. temp.: 1000-1430C
2. thick:10-50mm
3.density:200-450Kg/m3
Jiuqiang Industrial Refractory Ceramic Fibre Board are made from Jiuqiang refractory ceramic fiber, attending inorganic and suitable organic binders. Through vacuum processed into boards or formed shapes, they keep good mechanical strength after heating.
Advantige of Ceramic Fibre Board:
l Smooth surface
l Low impurity, and average bulk density and thickness
l Excellent mechanical strength and structural strength
l Low thermal conductivity
l Low shrinkage
l Resistant airspeed eroding
Application of Ceramic Fibre Board:
l Heat insulation materials for electro-thermal equipments,steel and metallurgy.
l Thermal insulation materials for construction.
l Back-up lining of high-temperature industry furnaces.
l Hot-face lining of ceramic kilns,heat-treatment furnaces and other industrial kilnsInsulation for furnace door and kiln car.
