Low Thermal Conductivity Ceramic Fiber Refractory Heat Storage , Heat Capacity
Low Thermal Conductivity Ceramic Fiber Refractory Heat Storage , Heat Capacity
Description:
Laure ceramic fiber blanket is composed of long,flexible,interwoven fibers manufactured by the “blown”and the “spun”process The product has excellent elasticity,great tenacity and half-hardness, causing no dust pollution.Made of refractory fibers which have high chemical stability,it is not only lightweight but having great heat-insulting effect.As a multi-application product,it caters for the complex thermal engineering requirements in various industries.
Features
1.Low thermal conductivity
2.Very low heat storage
3.Very high tensile strength
4.Thermal shock resistance
5.Sound absorption
6.Quick repairs.should lining damage occur,furnace can be cooled quickly
7.Contains no binder,no fumes or furnace atmosphere contamination
8.Contains no asbestos
9.No curing or dry out time,lining can be fired to operating temperature immediately
