Ceramic industry: the structure of light kiln car and the lining of the hot face of the kiln, the separation of the temperature zone of the kiln and the fire resisting material;
Glass industry: molten pool is lined with heat insulation and burner block.
Kiln building: hot face refractories (substitute for fiber blanket), heavy refractory lining, expansion joint;
Light industry: the lining of the combustion chamber of industrial and household boiler;
Petrochemical Industry: high temperature heating furnace lining hot surface material;
The building materials industry: the insulation of the cement rotary kiln and other equipment;
Product introduction:
Ceramic fiber blanket is used to strengthen a special needling process, this process does not contain any binder or other ingredients, by strengthening the needling process improving the anti hierarchical performance and the degree of woven carpet fiber, without affecting its flexibility and the excellent tensile strength. The installation method is simple, and the speed of the lining construction is speeded up greatly. In addition to hydrofluoric acid, phosphoric acid and strong alkali, the product is not eroded by most of the other chemicals.
