Product description:
WH ceramic fiber board is made of ceramic fiber cotton of corresponding grade, inorganic binder and a small amount of organic binder by vacuum molding, and the highest temperature resistance grade is 1800 ℃. In some equipment, a small amount of organic binder in the product will smoke when burned, which is a normal phenomenon and will dissipate soon.
Inorganic board: according to the needs of customers, all products are formed with inorganic binder, and there is no organic volatiles in use;
Hardened board: the product can be surface hardened or completely hardened according to customer needs, and its strength is better;
Waterproof permeable board: the surface of the product can be waterproof treated according to the needs of customers, and its water resistant permeability is greater than 98%, which is suitable for some special parts.
Pdoduct features:
◇ Flat surface
◇ Excellent high temperature resistance
◇ The unit weight and thickness are uniform
◇ Thermal shock resistance and chemical corrosion resistance
◇ Superior mechanical and structural strength
◇ strong resistance to airflow scouring
◇ Low thermal conductivity, low shrinkage and low bulk density
Typical application:
◇ Fire resistance and thermal insulation of furnace walls of various industrial furnaces and thermal equipment
◇ Ultra high temperature experimental electric furnace furnace materials
◇ Fire baffle
◇ Processed into sealing gasket and special-shaped products
