bio-soluble Refractory Ceramic Fiber Blanket Used for High Temperature
1. Description
It is made of high quality ceramic fiber spun bulk by using double inside needling methods which improve the tensile strength and the flatness of the ceramic fiber blanket.
Kmatai ceramic fiber blanket contains no organic binders which guarantee the stability and constructability of the ceramic fiber blanket at both high temperature and low temperature.
It is widely used in various sectors of refractory, insulation, thermal insulation field.
2. Main Tech
- All kinds of aluminium silicate fibre blanket, made from common, high pure, zirconic, chromic aluminium silicate fibre, after the process of needling, thermoforming, crossbar cutting, rolling up ,etc. which is through double-sided needling operation by using spun technology. All kinds of needling blanket not only have the same excellent function of corresponding aluminium silicate fibre, but also have low shrink and high tearing strength. In addition, the blanket own even texture and integrity surface.
- CT spun fibre blanket adopt high pure raw materials without any binding agent, ensure the product own good reliability and stability in any environment. the function of the blanket isn’t affected by water and oil, it will recover its thermal performance and physical property after drying.
- Needling blanket in different size and thickness provide users a wide range of material selection to gain the best heat insulation structure and energy saving effect.
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
