High density 1050 ℃ calcium silicate board for tunnel insulation? In the field of calcium silicate board, "high density" usually means higher strength and lower thermal conductivity, but weight also increases. In the field of industrial insulation, "tunnel" usually refers to the passage of tunnel kilns (used for firing ceramics and refractory materials) or industrial furnaces. For a high temperature environment of 1050 ℃, ordinary building calcium silicate boards are not suitable.
High density calcium silicate board (1050 ℃) specifically designed for tunnel insulation, especially for railway/highway tunnels and subway tunnels, is a hard, high temperature resistant, and high-strength insulation board for lining, fire insulation belts, and high-temperature exhaust ducts. Its core is high-density, 1050 ℃ resistant, vibration resistant, wind erosion resistant, and fire-resistant. The core functional advantages of high-density insulation calcium silicate board are:
1. High temperature resistant insulation (tunnel fireproof belt/smoke exhaust duct)
2. High density and high strength (key requirement for tunnels)
3. A-level fire retardant (mandatory for tunnel fire protection)
4. Moisture and water resistance (tunnel humid environment)
5. Frost resistance and weather resistance (outdoor/cold tunnel)
6. Construction and Durability
