硅酸铝板保温隔热耐火纤维板【湿法】祥雨硅酸铝耐火纤维厂

operating temperature:
heat depends on the type of atmosphere and material conditions of use.
technical characteristics:
low thermal conductivity, low heat capacity; excellent thermal stability and thermal shock resistance; high strength with good toughness.
applications:
1. industrial furnace wall lining, masonry insulation layer;
2. high-temperature furnace of the kiln liner, kiln cars, tailgate door, the furnace temperature to separate plate;
3. high-temperature, high temperature e, heat insulation, thermal insulation;
4. aerospace, ship building insulation, fire protection, sound insulation, insulation.

production process
a variety of aluminosilicate fiber, relative to the ordinary type, standard type, high purity type, with zirconia-based fiber made of silicon raw materials, use of vacuum suction filtration process or the rule of law into dried.
in addition to a variety of aluminosilicate fiberboard with the corresponding bulk properties of aluminosilicate fiber of cotton, the product of hard texture, excellent toughness and strength and excellent fire resistance, insulation performance. heating is not inflated, light, construction convenient, free shear bending is a furnace, piping and other e, the ideal energy-efficient insulation materials.
