特 point:
★ No deformation.The core material adopts the principle of arch bridge structure, local force is scattered, deformation is small after compression, thermal expansion and contraction, strong bearing capacity, excellent stability, water resistance and moisture resistance, no return of brine, no white crystal overflow.
★ fire resistance.The fire performance is excellent, the non-combustible level reaches GB8624-1997A level, the thermal conductivity is low, and the part is grilled at thousands of degrees, the back will not heat up, the burned part will not spread and expand, no smoke will be produced, and it is non-toxic and non-polluting.
★ Good flatness.Magnesium oxysulfide color steel composite board, the surface flatness is better than other core material products, and the cutting machine is formed and cut at one time, and the overall flatness error is within 0.1mm.
★ long life.The service life is not less than 20 years.
