What are the types of drywall? What are the types of gypsum board

1. Gypsum board on paper.

The upper and lower are made of paper as gypsum slurry as a sandwich core.

The texture is light and the fire resistance strength is high. Easy to process. Plain gypsum board is used for interior walls, partition walls and suspended ceilings.

Gypsum board with water-resistant treatment can be used on the walls of rooms with high humidity, such as kitchens, bathrooms, etc. There are many common gypsum boards, which can be divided into the following categories:

Plain paper gypsum board:

Gypsum board is the most economical, practical and most common kind of board, the general space humidity does not exceed 65, you can choose gypsum board. Thick, plain plasterboard is commonly used for suspended ceilings and lightweight partition walls.

Water-resistant gypsum board:

The water-resistant gypsum board has undergone special waterproof treatment on the surface and the core of the board, (the surface water absorption is not more than 160 grams, and the water absorption rate is not more than 10%). Water-resistant gypsum board is generally commonly used relative humidity.

No more than 95% of the places of use, such as toilets, bathrooms, etc.

Refractory gypsum board:

Refractory gypsum board is made by adding refractory materials and a large amount of glass fiber to its core.

Generally, it can be seen from the section) that the better ones will generally use alkali-free glass fiber, and the general ones will choose medium alkali or alkali glass fiber.

Decomposable formaldehyde gypsum board:

It can decompose formaldehyde gypsum board, and add long-lasting aldehyde net particles - chitin on the surface of the paper.

With nano-silicon wafers, the "aldehyde net power" generated can effectively adsorb free formaldehyde in the air and decompose formaldehyde into water molecules.

With non-toxic and harmless "oxime", it can achieve the effect of removing indoor formaldehyde and purifying the air. Zhongji building materialsLi Suting.

2. Cloth gypsum board.

Similarities between plasterboard on canvas and gypsum on paper:

1) The functional classification is the same, and it is also divided into: ordinary gypsum board, water-resistant gypsum board, fire-resistant gypsum board, etc.

2) The main material is the same, which is gypsum.

The difference between plasterboard on canvas and gypsum board on paper:

1) The surface material is different, one surface material is paper, and the other surface material is cloth.

2) Cloth gypsum board has good toughness, is not easy to crack, and is also higher than paper gypsum board.

3. Decorative gypsum board.

The main raw material is also building gypsum, which is mixed with a small amount of fiber to make a variety of patterned boards. It is generally suitable for top or wall decoration. It has the characteristics of light weight, fireproof, moisture-proof, easy processing and simple installation.

4. Gypsum hollow slat.

Gypsum hollow slats are also made of building gypsum. It is made by mixing the right amount of filler and fiber. Mainly used for non-load-bearing interior walls of buildings, which are characterized by the absence of a keel.

5. Fiber gypsum board.

Fiber gypsum board is made of building gypsum as the main raw material and mixed with an appropriate amount of fiber reinforcement material, the flexural strength of this board. High.

At present, there are three kinds of gypsum board in China: paper gypsum board, fiber gypsum board and hollow gypsum board.

Gypsum board is a lightweight sheet made of gypsum as the core material and reinforced by paper on both sides;

Fiber gypsum board is a lightweight sheet made of gypsum as a cementitious material and a variety of organic or inorganic fibers (such as paper fiber, grass fiber, glass fiber, etc.) as a reinforcing material, with a thickness of 8 12 mm and a weight of 7 9 kg m2;

Hollow gypsum slats are also hollow partition panels made of gypsum as cementitious material mixed with various lightweight materials or reinforcing fibers (such as expanded vermiculite, expanded perlite, glass fiber, etc.), with a thickness of 60 100 mm and a wall weight of 40 60 kg m2. Paper and fiber gypsum sheets need to be made of steel, wood, and gypsum keels as the skeleton to form partition walls. Because of its own rigidity, hollow gypsum slats can form partition walls without a skeleton.

Gypsum board is easy to cut and process, but it is also easy to be damaged, so special tools are required during transportation and installation. During construction and installation, in order to ensure that the joint does not crack, attention should be paid to the arrangement of the position of the plate joint, and the joint must be properly treated with special cementing materials.

Mainly: gypsum board, gypsum board, decorative gypsum board, gypsum hollow slat, fiber gypsum board, gypsum sound-absorbing board, positioning point gypsum board, etc.

1. Gypsum board on paper. Gypsum board is a lightweight board made of gypsum slurry as the sandwich core and paper on both sides. Gypsum board is light in texture, high in strength, fireproof, mothproof, and easy to process.

Plain paper-faced gyppool board is used for interior walls, partition walls and suspended ceilings. The water-resistant paper-faced gypsum board with fireproof treatment can be used for the wall of the room with high humidity, such as the lining of the tile, metal plate and plastic brick wall of the bathroom, kitchen, bathroom, etc.

2) Paperless gypsum board. It is a kind of wood generation with superior performance, a new type of building board with building gypsum powder as the main raw material and various fibers as reinforcing materials. It is a new product that has been successfully developed after the wide application of gypsum board on the paper surface.

Because the appearance omits the protective cardboard, therefore, in addition to covering the entire application range of the paper plasterboard, it has also been expanded, and its comprehensive performance is superior to the paper gypsum board.

3. 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., with a variety of patterns, decorative plates, such as gypsum printing board, perforated ceiling board, gypsum relief ceiling board, paper gypsum veneer decorative board, etc. It is a new type of interior decoration material, suitable for medium and high-grade decoration, with the characteristics of lightweight, fireproof, moisture-proof, easy processing, simple installation and so on.

In particular, the new resin imitation veneer waterproof gypsum board board is covered with resin, the veneer imitation pattern, its tone pattern is realistic, novel and generous, the board has high strength, pollution resistance, easy to clean, can be used to decorate the wall Hu Tan surface, do wainscoting and skirting boards, etc., is an ideal material to replace natural stone and terrazzo.

4. Gypsum hollow slat. Gypsum hollow slats are a kind of hollow slabs processed by adding an appropriate amount of lightweight filler or fiber materials with building gypsum as the main raw material. This kind of board does not use paper and binder, and does not use keel during installation, which is a lightweight board with relatively fast development.

Mainly used for interior walls and partition walls.

5. Fiber gypsum board. Fiber gypsum board is made of building gypsum as the main raw material and mixed with an appropriate amount of fiber reinforcement materials. The flexural strength of this board is higher than that of gypsum board, and it can be used for interior walls and partition walls, as well as in the replacement of wood for furniture.

In addition to the traditional gypsum board, there are also new products that are constantly increasing, such as gypsum acoustic panels, laminated boards, thermal insulation boards and gypsum composite boards. The specifications of gypsum board are also developing in the direction of high thickness and large size.

1. Gypsum board: A small amount of adhesive, fiber, foam and other substrates are added to the building gypsum, and an appropriate amount of water is added and mixed well, and then continuously poured between the two layers of protective paper, and manufactured by rolling, solidifying, cutting, drying and other processes. It has good toughness, a smooth surface, can be sawn, and is easy to construct.

It is mainly used for interior partition walls, interior wall veneers, ceilings, sound-absorbing panels, etc., but the water resistance sensitivity hole energy is poor, and it is not suitable for use in humid environments.

2. Fiber gypsum board: It is mainly composed of fiber and admixtures and other building gypsum slurry, which is formed by winding, filtering or rolling, and then cutting, coagulation and drying. Compared with gypsum board, its flexural strength is higher, and there is no need for paper and adhesive, but the capacity is larger, and the use of gypsum board is the same.

3. Decorative gypsum board: the prepared gypsum slurry is poured into the mold frame with patterns in the bottom mold, and the hall is made by smoothing, solidifying, demoulding, drying and other processes, and the thickness of the board is generally about 10mm. In order to improve its sound absorption, it can also be made into panels with perforated and blind holes, which are often used as ceilings and decorative walls.

Gypsum board is the use of gypsum as the main raw material, through the processing of the board, the traditional gypsum board is light weight, high strength, construction is very convenient, suitable for all kinds of construction, but there are many types of gypsum board, many inexperienced owners may only know a rough. So, what are the types of drywall? What are the main properties of drywall?

Let's take a brief look at it together.

First, the type of gypsum board.

Gypsum board types include: gypsum board, paperless gypsum board, decorative gypsum board, gypsum hollow slat, fiber gypsum board, plant straw gypsum board, gypsum composite board and gypsum sound-absorbing board, etc., with the progress of science and technology, the types and specifications of gypsum board are increasing, and its use is also broadening, in addition to being used as a base lining, it can even be used as a floor tile.

Second, what is the main performance of gypsum board.

1. The production energy consumption of gypsum board is low, such as paper gypsum board, which is mainly made of cementing material cooked gypsum, and its production energy consumption is at least 70% lower than that of ordinary cement.

2. Gypsum board has light texture and good thermal insulation performance, if the gypsum board is used as a partition wall, the weight of the same size and size, the gypsum board wall is only one-third of the brick wall, and because the gypsum board is a scattered hole structure, the thermal conductivity is also very good.

3. Gypsum board has good fire performance, because gypsum board will automatically release Lu's compound water in the case of heat, and the fire resistance limit is at least more than 2 hours in a high-temperature environment.

4. The decorative performance of gypsum board is good, because the surface of high-quality gypsum board is very smooth, and the board and the board are bonded together by cementing material, which will not leave gaps after bonding, and the decoration effect is good.

5. Gypsum board has good workability, strong nail holding ability, can be used for bonding, can also be sawn for use, very convenient, and use it to decorate, may effectively provide construction efficiency.

6. Gypsum board has a unique breathing performance, which can automatically adjust the indoor environmental humidity, and if the indoor humidity is high, it can automatically absorb moisture to create a comfortable living environment for the owners.

China's gypsum board has three kinds of absolute belts: paper gypsum lack macro board, fiber gypsum board and hollow gypsum board

1. Gypsum board is a lightweight thin board made of gypsum as the core material and reinforced by paper on both sides;

2. Fiber gypsum board is a lightweight sheet made of gypsum as a cementitious material and a variety of organic or inorganic fibers (such as paper fiber, grass fiber, glass fiber, etc.) as a reinforcing material, with a thickness of 8 12 mm and a weight of 7 9 kg;

3. Hollow gypsum slats are also hollow partition boards made of gypsum as cementitious materials and mixed with various lightweight materials or reinforcing fibers (such as expanded vermiculite, expanded perlite, glass fiber, etc.), with a thickness of 60 100 mm and a wall weight of 40 60 kg.
