Heat Resistant Ceramic Fiber Paper

Ceramic fiber paper in Rongsheng Xinwei is a kind of heat insulation ceramic fiber product with excellent quality manufactured with a raw material of paper grade ceramic fiber with the lowest slag content through processes of pulping, deslagging, pulp mixed, fourdrinier forming, vacuum dewatering, drying, cutting and rolling. Ceramic fiber paper has excellent high-temperature resistance and thermal insulation.

Ceramic fiber paper introduction

Ceramic fiber paper is a lightweight refractory material made by melting ore at high temperatures, spinning it into ceramic fibers, and then forming it through wet molding. Ceramic fiber paper has been widely used because of its superior performance.

Application of ceramic fiber paper

1. Steel industry: expansion joints, backing insulation, insulation sheets, and mold insulation;
2. Nonferrous metal industry: tundishes and launder covers, mostly used for casting copper or copper-containing alloys;
3. Ceramic industry: lightweight kiln car structure and kiln hot surface lining, kiln temperature zone division,n and fireproof materials;
4. Glass industry: melt pool backing insulation, burner block:
5. Kiln construction: hot surface refractory materials (instead of blankets), backing expansion joints of heavy refractory materials;
6. Light industry: linings of industrial boilers and household boiler combustion chambers;
7. Wall linings and backing materials for high-temperature reactions and heating equipment.
