1) Fireproof:The material is class A frameless and tested by state authority institute. Fire durability levels meet the demand for light inner partition completely2) Waterproof and moisture proof:Through experiment and test, after this material has been immersed in the water for one month, it keeps its original shape, without deformation or expansion. Its dry-wet deforming ratio is 0.26% and water-absorbing capacity is 15%. The creasing resistance is 15MPa under the dry condition and 22MPa under the moisture absorbing condition, I. E. The strength under the moisture absorbing condition is higher3) Heat preservation and protection:The thermal resistance is 1.14m2k. /w, matched with the exterior heat insulating material. It can be used as the external walls in general4) Sound absorb and insulation:95mm soundproof wall can have a soundproof standard as a 123mm wall made of four layers of 12mm gypsum plank, and equal to the soundproof effect of a 150mm common solid brick wall5) Lightweight and high intensity10mm thick board weights 10.7kg/cbm, the wall is made of light steel keel which is 31.5kg/cbm, is about 1/10 of common wall made of solid clay brick while the anti-impact intensity is 2-3 times of normal plaster wall. It can be easily installed and the constructing time is short .6) Environment protection:The material is made of natural materials such as minerals and plant fiber, the environment protection level meets our country's demand. It is new product that our country is encouraging.7) The seaming treatments:(A) The seaming of single cover board, or the seaming of two-layer cover board at one side of inner and outer layer should be arranged stagger, I. E., not on the same keel .(B) Please leave the seaming of 3-5mm when the boards dock(C) Clean the seaming of the board, and then fill the filling material (according to the features of the board, please use elastic material)(D) After the filling material has been filled
