Calcium silicate insulation board is a thermal insulation material made of silicon oxide, calcium oxide, and reinforcing fibers as the main raw materials, through the processes of stirring, heating, gelling, molding, autoclaving hardening, drying, etc.
Firebird Non-asbestos Calcium Silicate Board include three kinds, which are:
a. 1000℃ Calcium Silicate Straight & Arch Board;
b. 1100℃ Calcium Silicate Board for Fireproof & Sound Insulation Door;
c. High Density Calcium Silicate Board with glass fiber or carbon fiber reinforced;
Product forms include straight & arch board, pipe cover and CNC machined shapes.
Calcium silicate board widely used as thermal insulation in cement industry, aluminum smelter, power station, steel mill, glass industry, petrochemical industry, fireproof door core, fireplace, etc.
1. Raw Material:
– Lime dissolved, filtered, and mixed with diatomaceous earth, water glass, fibers, and water.
2. Mixing and Heating:
– Thick mixture heated and gelled, then transferred.
3. Molding:
– Hydraulic press used for molding.
– Options:
– Casting molding (simple molds, lower cost).
– Pressing molding (special presses, uniform appearance).
4. Autoclaving and Hardening:
– Products autoclaved for hardening.
5. Drying and Quality Control:
– Products dried for dehydration.
– Quality checked via sampling.
6. Storage:
– Approved products stored.
– Thermal Insulation: Calcium silicate boards are widely used in industrial settings for their excellent thermal insulation properties. They insulate furnaces, boilers, and high-temperature equipment to ensure efficient temperature control and energy conservation.
– Fireproofing: Calcium silicate insulation boards provide fireproofing for industrial installations by being applied as coatings on steel structures, walls, and ceilings, thereby enhancing their resistance to fire damage.
– Structural Protection: Calcium silicate board contribute to structural protection in industrial environments, reinforcing and shielding equipment and structural elements against mechanical stress, improving durability.
