Magnesium Plain Board(usually called magnesium oxide board) is combined system of MgO,MgCl2 and H2O alkali agent. The stable magnesium colloid is reinforced by middle alkali glass fiber net and stuffed by light material then becomes new frameless decorative material. It has the features of light quality, strong intensity, little contraction, easy constructing. Especially the unique waterproof, fireproof, corrosion proof and plasticity are better than normally used wooden multisplint, paper surface plaster board etc.

(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
