gypsum board

Paper-less gypsum board is a new building material developed by our factory through repeated research,which takes high-strength gypsum powder as the raw material and is mixed with high-quality fiberglass and special agent.It is widely used in suspended ceiling,partition and veneer wall . I the main material introduction Gypsum powder:It is high-strength gypsum powder.It is a kind of porous material with good sound insulating and heat insulating performance.In the case of moist indoor air,it can absorb moisture content in the air.when it is dry,it can release mosture content to adjust the temperature and humidity of the air and create a comfortable environment.You will have the feeling of returning back to the nature.The thermal conductivity of calcined gypsum is 0.099w/m,which is a special-grade fireproof material. Fiberglass: our fiberglass is alkali-free glass fiber through fiberglass cutting machine which is researched by us,the cutting length is the best one after repeated test. Special Additive: Adding to the additive into the gypsum powder in order to ensure product strength and water resistance. II Product feature Moisture resistanceThe board with the breathfeature can be suitable for coastal areas and humid place due to the characteristics fo gypsum powder. Fire resistanceThe product is A-glass fireproof incombustibility and detected by the National Fire Agency Heat preservationFiberglass gypsum board has good heat-insulation and heat preservation performance Sound insulationThe board has the good sound insulation performance as the surface density of the board is freater than the general wall material Efficient anti-crackThe board can be the perfect integration with the sealant as the whole due to non-paper on the sheet surface,greatly reducing the cracks. Enviromental protectionNatural gypsum powder and alkali-free fiber glass are environmental-friendly materails, the sheet is non-toxic and no side effect Installation method : 1.Make sure the actual height of installation of the main keel above the ground level 2.According to the distance among the main keels you need to line on the wall in order to fix the pendant 3.Hanging the main keel with the pedant 4.Connecting the rider keel to the main keel according to the requirement,and adjusting the pendant screw in order to make the keel frame stable and level 5.Connecting the fiberglass board with the rider keel by the screw , the screws distance is like the following: edge distance≤20cm, the middle distance ≤30cm 6. The fiberglass stained with the calcium plaster is to coverthe joint between rider keel and gypsum board , the fiberglasss Interval is 30 cm to 40cm ,and the shape is similar to saddle, the gaim is to make them stable 7.Filling the joint between the screw hole and board by the special sealant our manufacturer specially product the sealant, then fulling the whole surface of the board used by the common gypsum in order to make the surface smooth and clean 8.Rendering the surface according to the requirement on the painting Cetification: Our company has passed ISO9001:2000 international quality system certification in 2005.The company has obtained CCES registered trade mark approved by State Trademark Bureau in 2007.The access panel produced by company has obtained letter of patent approved by State Patent Office in 2008 .We have obtained Perfect Brand of GRGGRCand other gypsum products by The National Committee of Hi-Tech Building Materials Industry in 2009. Another,we also obtained Eviromental Protection of Building Material.The products has inspected by National Fire Equipment Quality Supervision and Inspection Center,Shanghai Construction & Science Institute, Institute of Acoustics of Tongji University and Shanghai Environmental Quality Supervision Station, all the indexes equal to or surpass those of same industry or the national standard.
