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.
