CS-1 Calcium Silicate Board

CS-1 calcium silicate board is a commonly used calcium silicate insulation material. In terms of service temperature, it belongs to Type II thermal insulation materials.

The main raw materials of CS-1 calcium silicate board are calcium hydroxide and quartz sand. It features high-temperature resistance, high strength, good toughness, and excellent thermal insulation, making it widely used in cement plants, metallurgical industries, and other fields.

The main raw materials of CS-1 calcium silicate board are calcium hydroxide and quartz sand. After the raw materials are ground and purified, reinforcing fibers are added and reacted in an autoclave. Once the reaction is complete, the mixture is poured into a press for pressure forming. The formed CS-1 calcium silicate boards are then placed into a 60-meter-long tunnel kiln for drying.

Advantages of CS-1 Calcium Silicate Board:

  1. High-temperature resistance: CS-1 calcium silicate board can be used at temperatures up to 1050 °C, making it suitable for various high-temperature environments.
  2. Excellent thermal insulation: With very low thermal conductivity, CS-1 calcium silicate board reduces heat transfer and energy loss, providing superior insulation performance.
  3. High strength: Produced with an improved manufacturing process, the board has high strength, which minimizes damage during installation and reduces construction costs.
  4. Good toughness: The board maintains its shape under prolonged high-temperature conditions, ensuring the stability of the refractory structure.
  5. Non-combustible and fire-resistant: Made primarily from inorganic materials, CS-1 calcium silicate board is non-combustible, offering excellent fire protection and flame retardancy.
  6. Sound insulation and noise reduction: CS-1 calcium silicate board can reduce the propagation and diffusion of sound, providing effective acoustic insulation.

Typical applications of CS-1 Calcium Silicate Board:

Cement industry: decomposition furnaces, preheaters, tertiary air ducts, kiln hoods, coolers, and smoke chambers;

Metallurgical industry: heating furnaces, soaking furnaces, walking beam furnaces, annealing furnaces, high-temperature flues, and hot air ducts;

Petrochemical industry: heating furnaces, ethylene cracking furnaces, hydrogenation furnaces, and catalytic cracking furnaces;

Ceramic industry: tunnel kiln walls;

Glass industry: furnace bottoms and walls of melting furnaces;

Power industry: preheating furnace pipelines and boiler linings;

Shipbuilding industry: deck coverings;

Nonferrous metal industry: electrolytic cells, etc.
