Gypsum board is a kind of material made of building gypsum as the main raw material. It is a kind of building material with light weight, high strength, thin thickness, convenient processing, sound insulation and fire prevention, etc. It is one of the new lightweight panels currently under development. Gypsum plasterboards have been widely used for interior partitions, wall cladding panels (replacement of wall plastering layers), ceilings, sound-absorbing panels, ground base panels, and various structures in residential buildings, office buildings, shops, hotels, and industrial plants. Kinds of decorative plates and so on.
Adding lightweight filler (such as sawdust, etc.) to gypsum reduces the weight and thermal conductivity of the gypsum board. Adding reinforcing materials (such as asbestos, hemp cutters, paper bars, etc.) can increase the strength of the plasterboard. Placing paper, plastic wallpaper, aluminum foil, etc. on the surface of the gypsum board improves the water resistance of the gypsum board. Plasterboards coated with polyethylene resin or chemically treated waterproof paper can be used in bathrooms or outdoors. China's current production of gypsum board mainly include: gypsum board, gypsum board, gypsum hollow board, fiber gypsum board and gypsum board.
(l) Paper gypsum board
Gypsum board is a kind of light board made of gypsum slurry sandwiched on both sides with paper as protection surface. Paper gypsum board is light in texture, high in strength, fireproof, tamperproof and easy to process. Plain plasterboard is used for interior walls, partition walls and ceilings. Fire-resistant water-resistant gypsum board can be used for room humidity walls. Such as toilets, kitchens, bathrooms and other tiles, metal panels, plastic brick wall liner.
(2) decorative gypsum board
Decorative gypsum board is a kind of plate made of building gypsum as the main raw material, mixed with a small amount of fiber materials, etc., with various patterns and floral ornaments. Such as gypsum board, perforated ceiling board, gypsum relief ceiling board, paper gypsum veneer decorative board and so on, is a new type of interior decoration materials, suitable for medium and high-grade decoration, with light weight, fire, moisture, easy processing, Simple installation and other features. In particular, the new resin imitation type waterproof gypsum board surface covered with resin, decorative imitation pattern, its vivid color pattern, novelty, high sheet strength, resistant to pollution, easy to clean, can be used to decorate the wall, do the retaining wall The board and skirting board are ideal materials to replace natural stone and terrazzo.
(3) Gypsum hollow strip
Gypsum hollow strip is a kind of hollow plate which is made of building gypsum as the main raw material, and is processed by adding appropriate amount of light filler or fiber material. This kind of sheet does not need paper and binder, and it does not need keel when it is installed. It is a lightweight sheet that develops relatively quickly. Mainly used for interior walls and partition walls.
(4) Fiber Plaster Board
Fibre gypsum board is made of building gypsum as the main raw material, and is made by adding appropriate amount of fiber reinforced materials. The flexural strength of this kind of plate is higher than that of gypsum board, which can be used for interior walls and partition walls, and it can also replace wood to make furniture.
In conventional gypsum boards, the output of gypsum board and gypsum board is increasing, and the output of gypsum board is decreasing. There are also new products, such as plasterboards, fireproof panels, thermal insulation panels and gypsum composite panels. Gypsum board specifications also develop in the direction of high thickness and large size.
In addition, the use of gypsum products is also widening. In addition to being used as a base village, it is also used as a surface decoration material, and even as a floor tile, an exterior wall substrate, and a wall core material.
