Gypsum board is a kind of material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation and fire prevention, and it is one of the new lightweight boards that are being developed emphatically at present. Gypsum board has been widely used in interior partitions, wall coverings (instead of wall plastering), ceilings, sound-absorbing boards, ground base boards and various decorative boards of various buildings such as houses, offices, shops, hotels and industrial plants.
Gypsum board Gypsum board (divided into ordinary paper gypsum board (commonly used), fiber gypsum board and gypsum decorative board "description") is made of gypsum as the main raw material, adding fiber, adhesive and modifier, mixing, pressing and drying. It has the characteristics of fire prevention, sound insulation, heat insulation, light weight, high strength, small shrinkage, good stability, no aging, moth prevention and so on, and can be constructed by nailing, sawing, planing and gluing.
Gypsum boards produced in China mainly include: paper gypsum board, decorative gypsum board, gypsum hollow lath, fiber gypsum board, gypsum sound-absorbing board, anchor gypsum board and so on.
(l) gypsum board paper. Gypsum board is a kind of light board, with gypsum slurry as interlayer and paper as protective surface on both sides. Gypsum board is light in texture, high in strength, fireproof, moth-proof and easy to process. Ordinary gypsum board is used for interior walls, partitions and suspended ceilings.
Paper waterproof gypsum board, with a certain amount of waterproof agent added to the gypsum core material (because gypsum has moisture-proof function and moisture absorption function), can be used for room walls with high humidity, such as bathrooms, kitchens, bathrooms and other areas, but can not be soaked in water for a long time.
(2) Decorative gypsum board. Decorative gypsum board is made of building gypsum as the main raw material and a small amount of fiber materials. There are many patterns and decorations, such as gypsum printed board, perforated ceiling board, gypsum embossed ceiling board, paper gypsum decorative board, etc. It is a new type of interior decoration material, suitable for middle and high-grade decoration, and has the characteristics of light weight, fire prevention, moisture resistance, easy processing and simple installation. In particular, a new type of resin imitation facing waterproof gypsum board is covered with resin and decorated with imitation patterns. Its color pattern is vivid, novel and generous, and the plate has high strength, pollution resistance and easy cleaning. It can be used to decorate walls, make wallboard and skirting board, and is an ideal material to replace natural stone and terrazzo.
③ Gypsum hollow lath. Gypsum hollow slat is a kind of hollow slab made of building gypsum as the main raw material and adding appropriate light filler or fiber material. This kind of board does not need paper and adhesive, and it does not need keel when it is installed. It is a kind of fast-developing optical plate. Mainly used for interior walls and partitions.
(4) fiber gypsum board. Fiber gypsum board is made of building gypsum as the main raw material and adding a proper amount of fiber reinforced materials. The bending strength of this board is higher than that of gypsum board, which can be used for interior walls and partitions, and can also replace wood to make furniture.
In addition to the traditional gypsum board, new products are also increasing, such as gypsum sound-absorbing board, fire-proof board, insulation board, gypsum composite board and so on. The specifications of gypsum board are also developing in the direction of high thickness and large size.
(5) Planting straw gypsum board. Different from ordinary gypsum board, due to the use of a large number of plant straws, the local waste is fully utilized, which not only solves the environmental protection problem, but also increases the economic income of farmers, reduces the weight of gypsum board, reduces the transportation cost, and reduces the coal and electricity consumption by 30%-45%, which fully conforms to the relevant national industrial policies.
(6) Anchor gypsum board The second generation gypsum board-Bayer Anchor gypsum board
This product is a new generation of patented gypsum board product which is successfully developed by Bayer Company due to the actual needs of the project and after years of painstaking research, and meets the national building code. This product is refined from Bayer exclusive high-grade white wood pulp protection paper and high-quality gypsum and other raw and auxiliary materials, and the surface of the product is whiter. According to the requirements of national construction specifications, accurate construction and installation positioning points are set in advance on the gypsum board construction surface to make the project construction better and faster.
In addition, the use of gypsum products is also expanding, not only as a base lining, but also as a surface decoration material, and even as a floor tile, an external wall substrate and a wall core material. Sue smoke
