Fireproof Insulation Refractory Ceramic Fiber Blanket For Furnace 1260℃
Fireproof insulation 1260C Refractory ceramic fiber blanket for furnace
1. Description
Ceramic fiber blanket from ceramic fiber wool, natural refractory raw material, and a small amount of organic binder, and adopting the completely automated control continuous production technology. Because of the high fiber content, it has the characteristics of high temperature, light weight, and heat shock resistance, which is one of the important guarantee factors of kiln energy-saving, cost-reducing, high quality and yield, can be widely used in industrial kiln heat insulation layer.
Ceramic Fiber Blanket is an ideal thermal insulation , fire-proofand sound-absorbing material. The Ceramic Fiber Blanket is composed of long, flexible, interwoven fibers manufactured by the blownand the spunprocess yielding a strong, light weight, durable blanket for applications in a temperature range from 1100° C (2012° F ) to 1430° C (2600° F).The ceramic fiber blanket is completely inorganic and is needled to provide exceptional handling strength,used in a variety of heat processing applications.
