Heat resistant fire proof Refractory ceramic fiber blanket for boiler insulation
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.
2. Characteristics
Low thermal capacity, low heat conductivity
Non-brittle material, good elasticity
Good wind erosion resistance performance, long service life
Excellent thermal stability and thermal shock resistance
Good Sound-absorbing performance
Rigid, self-supporting plate
Good anti-strip performance
Easy molding and cutting
3. Features
- Low heat strong capacity, Low thermal conductivity
- Excellent thermal stability and shock resistance, resist devitrification at high temperature
- Excellent tearing resistant
- Excellent insulating performance, fire prevention and sound absorption
- Double—side needling operation produces tough, resilient and strong blankets, which resist tearing both before and after heating.
- Easy cutting and installation
