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.
