Background

The microporous calcium silicate heat-insulating tile block is a common heat-insulating material for heat-insulating pipelines, has the characteristics of low volume weight, high strength, small heat conductivity coefficient, high temperature resistance, corrosion resistance, long service life and the like, and effectively solves the problems that a soft heat-insulating material is easy to collapse and is not resistant to pressure. However, the traditional microporous calcium silicate heat-insulating tiles are straight-edge arc-shaped plates or flat plates, and when the tiles are coated on pipelines or equipment, the tiles are difficult to be closely attached, and straight seam gaps are easy to form so as to cause convection heat transfer. The conventional solution is to use calcium silicate plastering material for caulking, but the method wastes time and labor, the plastering material cannot fill the whole gap, after long-time use, the plastering material is disjointed with the tile block due to the effect of expansion with heat and contraction with cold, and the problem of heat dissipation through the gap cannot be thoroughly solved.
