        Many types of gypsum board, gypsum board common in the market are the following four categories:
        General plaster board
        Ivory white board core, gray paper, is the most economical and common varieties. For no special requirements of the use of places, the use of continuous relative humidity does not exceed 65%. Because of the price, many people like to use 9.5mm thick ordinary gypsum plasterboard to make the ceiling or the wall, but as 9.5mm ordinary gypsum plasterboard is relatively thin, the intensity is not high, so it is easy to deform under wet conditions, therefore It is recommended to use more than 12mm gypsum board. At the same time, the use of thicker sheets is also an effective way to prevent seam cracking.
        Water-resistant plaster board
        Its core and face paper have been waterproof, according to the national standard requirements, waterproof paper gypsum board and core must meet certain waterproof requirements (surface water absorption of not more than 160 grams, the water absorption of not more than 10 %). Water resistant gypsum board for continuous relative humidity less than 95% of the places of use, such as toilets, bathrooms and so on.
        Fire-resistant plaster board
        The core adds refractory material and a large amount of glass fiber. If the gypsum board is cut, a lot of glass fiber can be seen from the cross section. Good quality fire-resistant gypsum plaster board will use good fire-resistant properties of alkali-free glass, the general products are selected in the alkali or high alkali glass
        Moisture-proof gypsum board
        Has a high surface moisture resistance, surface water absorption of less than 160g / ㎡, moisture-proof gypsum board for large room ceiling, wall and veneer.
