The main characteristics of gypsum powder condensation hardening fast. Hardening volume micro-expansion. Lime and cement and other cementitious materials often produce hardening contraction, while building plaster is slightly expanded (expansion rate of about 1%), which enables the smooth surface gypsum products and full, clear edges and corners, does not crack when dry. After hardening large porosity, apparent density and lower strength. Good sound absorption insulation performance. Good fire resistance. In case of flint, the main component of gypsum plaster after hardening of the crystal water evaporates and absorbs heat, a steam curtain article surface, can effectively prevent the spread of fire. A certain thermostat moist. Poor water resistance and frost resistance. Good processing performance. Gypsum products can be sawed, planed construction of high-strength gypsum powder, nails, drill. Building gypsum powder gypsum fiber board uses a fiber material (glass fiber and more) gypsum board construction gypsum powder as reinforcing material, and construction gypsum, retarders, water, etc. made by a special process. Higher than the strength of the fiber gypsum board gypsum board, its basically the same specifications. Except for the fiber gypsum board walls, interior wall, can also be used instead of wood to make furniture. Decorative gypsum board construction by building gypsum plaster powder manufacturers, the amount of fiber material and water by mixing, pouring, trimming, made drying process. Beautiful shape decorative gypsum board, decorative, and has good sound absorption, fire and other functions Beijing building gypsum powder, mainly for public buildings interior walls, ceiling and so on. Hollow gypsum plasterboard to the main building, adding the right amount of light porous materials, fibrous material and water by mixing, pouring, vibration molding, core pulling, stripping, drying made. Mainly used for walls, interior walls, etc., when used without keel. Gypsum flour mill building | building gypsum powder | Manulife Manulife gypsum plaster by Tai'an City Processing Limited.
