Fireproof board (usually called magnesium oxide board) is combined of MgO, MgCl2 and H2O alkali age Fireproof board (usually called magnesium oxide board) is combined of MgO, MgCl2and H2O alkali agent. The stable magnesium colloid is reinforced by middle alkaliglass fiber net and stuffed by light material then becomes new frameless decorativematerial. It has the features of lightweight, strong intensity, little contraction and easyconstructing. Especially the features of unique waterproof, fireproof, corrosionproof and plasticity are better than normally used wooden multisplint, paper surfaceplaster boards. 1) Fireproof:The material is class A frameless and tested by state authority institute. The waterabsorb and max. fire durability levels meet the demand for light inner partitioncompletely2) Waterproof and moisture proof:Through experiment and test, after this material has been immersed in the water forone month, it keeps its original shape, without deformation or expansion. Itsdry-wet deforming ratio is 0.26% and water-absorbing capacity is 15%. The creasingresistance is 15MPa under the dry condition and 22MPa under the moisture absorbingcondition, 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 fourlayers of 12mm gypsum plank, and equal to the soundproof effect of a 150mm commonsolid brick wall5) Lightweight and high intensity 10mm thick board weights 10.7kg/cbm, the wall is made of light steel keel which is31.5kg/cbm, is about 1/10 of common wall made of solid clay brick while the anti-impactintensity is 2-3 times of normal plaster wall. It can be easily installedand the constructing time is short6) 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 encouraging7) The seaming treatments:(A) The seaming of single cover board, or the seaming of two-layer cover board atone side of inner and outer layer should be arranged stagger, i.e., not on thesame 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 (accordingto the features of the board, please use elastic material) (D) After the filling material has been filled and curdled, cover glass net on theseaming and then paste putty, paste craft paper and make smooth surface treatmentof the board (E) Remove dust and putty then make dry treatment (F) Select proper grouting agent to paste wallpaper, paint dope and spray plastic(G) Select proper grouting agent to adhere aluminum plastic board (H) Ways of sticking the tiles: a) Choose the proper tiles to stick onto the surface with glueb) Lay a base on the surface of the board with cement and grout at a ratio of 1:3plus 0.5 lime and hang a steel mesh to have a roughcasting treatment, then stickwith the cement and grout at a ratio of 1:1 Used for outer packing of pipe lines:In modern construction, the package of the pipes is also very important. Packingthe pipes with our glass-magnesium can both resist the fire and moisture and worksas a decoration.
