Ceramic Fiber Blanket Introduce
Ceramic Fiber Blanket is composed of long flexible, interwoven fibers manufactured by the “spun” process yielding a strong,lightweight, durable product. This material can be used for applications with temperatures from 1000°F (538°C) to 2600°F (1425°C).The product is firm, light and durable.Thermal and physical properties are retained after drying following wetting by oil, steam or water. This ceramic fiber blanket products are completely inorganic, so there are no fumes when heating for the first time.Rongsheng ceramic fiber blanket has higher tensile strength and longer service life.
Production Advantages:
1. Excellent thermal stability,low heat storage,low shrinkage,low thermal conductivity
2. Good obstructing voice and mechanism streng
3. Good springiness for fibers,resistance to thermal shock
Typical Application:
1.Industrial furnace, heating devices, high temperature pipe wall linings,high temperature filter materials
2.High tempeture boilers, steam turbine and Nuclear power thermal insulation
3.Chemical industrial high-temperature reaction equipment and heating equipment wall linings
4.High building fireproof and thermal insulation,furnace door and roof thermal insulation
