Product description:
Refractory ceramic fiber blanket system using fiber-forming melt-blowing, especially by strengthening needling process, high-temperature heat setting from the fiber blanket. The blanket has all the characteristics of lightweight refractory casual cotton products but also has good insulation properties and mechanical strength, ease of processing and installation.
Features:
Low thermal conductivity, low thermal capacity; thermal shock, corrosion resistance, good anti-crystallization properties; excellent chemical stability; fiber elastic, high-temperature shrinkage; ease of processing, installation;
Applications:
Industrial furnaces, heating devices, heat pipe; gas turbines and nuclear power boilers, heat-sealed; fire protection and high-temperature thermal insulation equipment; high-temperature reaction equipment and heating equipment lining the walls; high-temperature filter material;
