Ceramic fiber boards are made from different types of ceramic fibers, attending inorganic and suitable organic binders. The mixture is vacuum processed into boards or formed shapes that keep good mechanical strength after heating. Physical stability up to 1800℃.
In some devises, it is a normal that produces smoking when a little of organic bonder is burnt, but it will be disappeared quickly
Inorganic board: All made of inorganic binder according to customer’s request, there is no organic volatile in use
Hardening board: Produce surface hardening or completely hardened according to customer’s request, make a better strength.
Hydrophobic board: Deal with surface waterproof according to the customer’s request,
Hydrophobic rate is more than 98%, which is suitable for some special parts.
Characteristics:
Smooth surface
Uniform density and thickness
Excellent mechanical strength and structural strength
Low thermal conductivity, low thermal shrinkage, low thermal capacity
Excellent insulation property
Resistance to heat shock, resistance to erosion
Resistance to airspeed eroding
Typical Applications
Various industrial furnaces, thermal devices wall refractory insulation
All other kiln backing such as petrifaction, metallurgy, ceramic and glass industry
Used as ultra high temperature electrical furnace hearth materials
Fireproof plate
Used as high temperature heating equipment backing lining to preserve and insulate the temperature
Produced sheet gasket and special from product
