Product Description

Paper-faced gypsum board uses natural gypsum and guarding surface paper as its main raw materials, mixing with adequate fibre, starch, coagulant agent, vesicant and water and so on produced a new type of light construction sheet. As the paper-faced gypsum board has the advantages of light, fireproofing, sound insulation, heat preservation, heat insulation, strong sound processing (which can be planed, nailed and cut), construction convenient, removable performance, increase the use of the area and so on. So it is used in commercial office buildings, schools, shops, residential, bus terminal, railway stations, airports, scientific research establishments, restaurants, hospitals, cinemas, arena, KTV and other industrial buildings and civil construction, particularly in high-rise buildings can be used as the internal wall material and decoration material. Such as shelves structure for non-load bearing walls, indoor paste metope board, celling and so on. Paper-faced gypsum board has many types while there are three common categories in the market as following: 1. Common paper-faced gypsum board: ivory board core, gray paper, is the most economic and common varieties. No matter brushing primer in his surface or directly as the end surface can give the desired results. It applies to the place where have no special requirements and the using place where the relative humidity is no more than 65%. 2. Water-resistant paper-faced gypsum board: It was developed and produced as a light plate to resist indoor high humidity environment. Its gypsum core was mixed with high-performance organic thinning agent as well as the special treated import waterproof paper. All these greatly improve and enhance the water resistance and hydrophobic of gypsum board. The water-resistant paper-faced gypsum board applies to the place where the relative humidity is no more than 95%, such as toilets, bathrooms, kitchens and so on. 3. Fire-resistant paper-faced gypsum board: After special treated pink paper is used as the guarding surface paper. Its board core adds fire-resistant materials and lots of glass fiber. Particularly applies to celling, walls, elevators, the lining of the secure access, staircases, as well as the wrapping of the columns, beams which has high requirements of fire-resistance. As a kind of new construction material the paper-faced gypsum board has the characters as following: (1) Low production consumption, high production efficiency. Saving 78% consumption comparing with cement while producing the same unit. Also large capacity and low investment, simple process for mass production. (2) Light: using the paper-faced gypsum board as the separating walls, its weight is only 1/15 of the same thickness comparing with the brick wall, 1/10 of block wall, in favor of anti-seismic, and effectively reducing the cost of base and main structure. (3) Keeping temperature and insulation: there are about 60% pores in the paper-faced gypsum board core. due to a very small thermal conductivity of air, it has good insulation
