Introduction of Cal-Sil Board
Ronghua calcium silicate board is a new type of thermal insulation material. Its main raw materials are high-quality silica and calcium materials. These raw materials are converted into calcium carbonate boards after hydrothermal treatment. This material is fire-resistant, lightweight, versatile, and easy to construct. It represents a new breakthrough in the application of thermal insulation materials. Ronghua calcium silicate board brings better results and performance to the application of the high-temperature thermal insulation industry.
Advantages of Ronghua Calcium Silicon Board
Calcium silicate panels are a type of refractory boards. Compared with ceramic fiber insulation board, it has the following main advantages:
- Excellent fire resistance;
- Good thermal shock resistance;
- Excellent thermal insulation and heat preservation effect;
- Low thermal conductivity (0.065-0.138W/(m·K)) among 100-600ºC;
- Low density (230-270±10%kg/m³);
- Good sound absorption capacity;
- Strong resistance to chemical erosion;
- Good mechanical properties;
- Excellent electrical insulation performance;
- Good machinability.
Applications of Ronghua Calcium Silicate Boards
- High-temperature kilns: Lining (steelmaking furnace, electric furnace, heat treatment furnace, chemical reaction kettle, boiler, ceramic furnace, cement furnace, etc.).
- Building fire protection: Building walls, roofs, partitions, firewalls, fire doors, fire shutters, etc.
- High-temperature pipelines: High-temperature steam pipelines, hot air pipelines, oil refining pipelines, hot oil pipelines, insulation pipelines, etc.
- Other applications: It can also be used in aerospace, home appliances and other fields.
