Introduction
Calcium silicate board is a kind of board dominated by silicic and calcic materials and made by such manufacturing process as pulping, shaping, steam curing, drying and post processing etc.Its highest working temperature is 1050 ℃, can be widely used in metallurgy, petroleum, chemical, mechanical, electrical, light industry and other industrial kiln.
The products sold well all over the world and exported to Japan, South Korea, Thailand, Indonesia, Malaysia, Pakistan, Vietnam, Hong Kong, Singapore and other countries and regions. Using the materials can reduce equipment heat loss, narrow the kiln size, and improve working conditions.
- High strength: in the condition of similar bulk density, it is the highest strength insulation material in inorganic hard insulation material
- Heat resistance: no deformation in working temperature
- Thermal insulation: lower thermal conductivity than other hard block insulation material
- No asbestos: avoid various diseases caused by the asbestos fiber and other harmful substances
Specification
Density: 170-500 kg/m³
Raw materials: Quartz sand
Thickness: 25-100 mm
Asbestos: 100% Non Asbestos
Function: Thermal insulation, fire proof
Application
Used in electric power, heat and other roads, chemical, metallurgical and other industries equipment, heat pipe, boiler body, kiln and so on. In recent years, widely used in thermal power plant heating pipe straight steel casing steel, plastic sets of steel, with glass fiber reinforced concrete composite insulation pipe, and can be processed into special-shaped products.
