fire-proof board

Description

Common Magnesium Oxide Board: 1, Characteristic of Common Magnesium Oxide Board Fireproof and burning retardent According to the inspection standard of national authoritative organization, our MGO board can reach grade A non-combustible, the partition wall system constructed with this kind of board has a good burning retardent effect, with fire-retardent limit higher than the national standard. Waterproof and moistureproof Through inspection, our MGO board can still stay intact after being soaked in water for one month without swelling and deforming. Its deforming rate is 0.*6% at wet and dry state, and water-absorbing rate is *5% around. Especially its bending-strength can reach *8Mpaat dry state, and can reach *2Mpa at moisure-absorbing state, namely it bending strength is higher at wet state, fully proving its good water and moisture resistance. Sound insulation Wall with this kind of board has a good sound insulation effect, *5mm wall with this board can reach the sound insulation effect of **3mm wall with four layers of *2mm gypsum boards, equivalent to the sound insulation effect of **0mm ordinary solid clay brick wall. Warm preservation and heat insulation Our MGO board has a thermal resistance of 1.*4?k/w, with a good warm preservation and heat insulation effect. Light weight and high strength Our MGO board is light in weight, its thickness can be 3mm to *2mm, if for ceiling 3mm to 6mm is ok, if for wall, 9mm to *2mm is ok, this can save transportation cost and make installation fast and convenient. At the same time, our board has a fine anti-impact strength, the weight of *0mm thick board is *0.*7kg/m2, parttion wall of light steel keel structure with this board is *1.5kg/m2, but its anti-impact strength is **3 times higher than ordinary gypsum board wall. Environmentally friendly Our MGO board is made of natural materials such as inorganic ingredient, plant fiber and so on, Excluding a
