Advantages of Ceramic Fiber BlanketsCeramic fibre blanket burnings can be used at temperatures up to 1430ºC. They can withstand high-temperature working environments and maintain normal performance, extending the life of the kiln.
These blankets will not deform structurally under rapid temperature changes. They have low permanent linear change. It is important that they provides protection for the kiln under thermal shock conditions.
The thermal conductivity of Kerui ceramic fireproof blanket is low. The thermal conductivity is between 0.09-0.76 W/mK at 400-1000°C. Moreover, this provides good thermal insulation for the furnace.
The ceramic blanket insulation has strong mechanical properties (like ceramic fire board), like tensile strength, wear resistance, tear strength, elasticity, etc. This is a good anti-deformation ability.
Kiln fibre blankets have good chemical stability. They resist most acidic and alkaline chemical erosion. In addition, they have good high-temperature oxidation resistance in applications.
Blanket ceramic fibers have a porous structure, high density and light weight. They can effectively absorb sound waves and block sound transmission. Moreover, this can improve the high-temperature working environment.
