What is gypsum board?

Gypsum board is a 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, heat insulation, fire protection and other good performance, and is one of the new lightweight panels that are currently focused on development. Gypsum board has been widely used in interior partition, wall cladding (instead of wall plastering), ceiling, sound-absorbing board, ground base plate and various decorative boards of various buildings such as residential buildings, office buildings, shops, hotels and industrial plants. It is not suitable for indoor installation in bathrooms or kitchens.

What are the types of gypsum board?

  • Gypsum board paper

Paper-faced gypsum board is a lightweight board with gypsum slurry as the core and paper as the cover on both sides. Paper-faced gypsum board is light in texture, high in strength, fireproof, mothproof and easy to process. Ordinary plasterboard is used for interior wall, partition wall and ceiling. Water-resistant paper-faced gypsum board after fire prevention treatment can be used for the walls of rooms with high humidity, such as the lining board of ceramic tile, metal plate and plastic brick wall in toilets, kitchens and bathrooms.

  • Decorative gypsum board

Decorative gypsum board is made of building gypsum as the main raw material, mixed with a small amount of fiber materials, etc., and has a variety of patterns and decorations, such as gypsum printed board, perforated ceiling board, gypsum relief ceiling board, paper-faced gypsum decorative board, etc. It is a new type of interior decoration material, suitable for middle and high grade decoration, with the characteristics of light weight, fire prevention, moisture-proof, easy processing, and simple installation. In particular, the surface of the new resin imitation decorative waterproof gypsum board is covered with resin, and the decorative imitation pattern is lifelike, novel and generous. The board has high strength, pollution resistance and easy cleaning. It can be used to decorate the wall, make wall panels and skirting boards, and is an ideal material to replace natural stone and terrazzo.

  • Fiber gypsum board

Fiber gypsum board is made of building gypsum as the main raw material and mixed with appropriate amount of fiber reinforced materials. The bending strength of this kind of board is higher than that of paper-faced gypsum board. It 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 increasing, such as gypsum sound-absorbing board, fire-resistant board, thermal insulation board and gypsum composite board. The specification of gypsum board is also developing towards high thickness and large size.

  • Plant straw plasterboard

Unlike ordinary gypsum plasterboard, it uses a large amount of plant straw to make full use of local waste, which not only solves the environmental protection problem, but also increases the economic income of farmers, reduces the weight of gypsum plasterboard, reduces the transportation cost, and reduces the consumption of coal and electricity by 30% – 45%, fully in line with the relevant national industrial policies.

  • Gypsum hollow batten

Gypsum hollow batten is a kind of hollow board processed with building gypsum as the main raw material, mixed with appropriate amount of lightweight filler or fiber material. This kind of board does not need paper and adhesive, and does not need keel during installation. It is a kind of light board with relatively fast development. Mainly used for internal walls and partitions. Gypsum board TV wall has many shapes, which can be designed according to your preferences. During construction, the thickness of the floor tile or floor tile and the height of the skirting line should be taken into account to coordinate the various shapes. If there is no skirting line, the installation of panels and gypsum boards should be after the ground construction to prevent moisture.

What is the difference between waterproof gypsum board and ordinary gypsum board?

The core board, surface layer and surface layer materials of ordinary gypsum board have not been waterproof; However, the core board, surface layer and surface layer materials of waterproof gypsum board have been waterproof.

The surface of ordinary gypsum is gray paper with the same color on both sides; Waterproof gypsum board, also known as cement pressure board, has white and black gray. Its surface is smooth on one side and rough on the other.

Waterproof gypsum board only has the property of water resistance. Compared with ordinary gypsum board, it will not deform, mildew, fuzz, pulverize, etc. after being soaked in water, but it will not prevent water infiltration and immersion.

Waterproof gypsum board is PVC plastic surface, and some gypsum boards are also mixed with glass fiber, which is called glass fiber PVC surface gypsum board. Ordinary gypsum board is paper-faced, commonly known as paper-faced gypsum board.
