1)Fireproof The material is A class frameless one tested state authority institute. The water absorb and max fire durability meet the demand for light inner partition completely. (2)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%,its water-absorbing capacity is 15%,especially 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 higher. (3) 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 general. (4) Sound absorb and insulation 95mm soundproof wall can have a soundproof standard which a 123mm wall made of four layers of 12mm gypsum plank, which is equal to the soundproof of effect of a 150mm common solid brick wall. (5)Light quality and high intensity 10mm thick board weights 10.7Kg/m2, use the wall made of light steel keel is 31.5Kg/m2 at 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 shortened. (6) Green environment protection The material is made of natural materials such as minerals and plant fiber, the environment protection meets our country's demand. It is new product that our country is encouraging.
