How is Drywall Made?

Gypsum board is a material made of building gypsum as the main raw material. It is a kind of light weight, high strength, thin thickness, convenient processing, sound insulation and fireproofing and other good construction materials. It is one of the new light-weight panels that are currently focusing on development.

The main gypsum boards produced in China are

Length: 1500 '' 2000 2400 2700 3000 3300 3600

Width: 900 1200

Thickness: 9.5 12 15 18 21 25 12.7 15.9

Note: According to user requirements, other specifications and sizes of plates can be produced. ^[1]

1. Before formal construction, workers must use a horizontal pipe to measure whether the ink line on the wall is level. Only if the true level of the base line is ensured, will it not cause the suspended ceiling to be installed later or have a height difference. 2. The gypsum board ceiling needs to be fixed on a solid wooden keel frame. Therefore, careful selection of the keel material has become an indispensable step. It is recommended that you try to choose a pine material with better nail holding strength. 3. Because the keel is made of wood, you must pay attention to fire prevention. The standard practice is to evenly apply fire-resistant paint on the surface of the keel, and when the entire keel is white, nail it to the wall, which can ensure its compatibility with

Preparation: modified starch, retarder, pulp, water reducing agent, water after quantitative measurement

(1) Low energy consumption in production. The cement used for the production of paper-faced gypsum board, the cement used in plaster, has a unit production energy consumption that is 78% lower than that of cement.

(2) Lightweight insulation. Using plasterboard as a partition wall, the weight is only 1/3 1/4 of the brick wall. At the same time, due to the porous structure of gypsum board, its thermal conductivity is 0.30. Compared with brick (0.43) and concrete (1.63), it has excellent thermal insulation performance.

(3) It has excellent fire resistance. Because gypsum releases compound water when heated, its fire resistance can reach more than 2h.

(4) Good decorative function. The surface of the gypsum board is flat, and the board and the board can be firmly bonded together by cement, forming a seamless structure, and the building decoration effect is good.

(5) Good workability. Gypsum board can be nailed, sawn, and sticky, and it is very convenient to construct. Using it for decoration can get rid of the traditional wet operation and greatly improve the construction efficiency.

(6) Comfortable living function. Due to the unique "breathing" performance of gypsum board, it has the ability to adjust indoor humidity and make living comfortable.

(7) High production efficiency. It is conducive to large-scale production. Among various building boards, the production efficiency of gypsum board is the highest, which is convenient for large-scale production.

(8) Low investment. Compared with fiber gypsum board and cement foam board, gypsum board production equipment can achieve continuous mechanized production, the equipment utilization rate is very high, and equipment investment is small. ^[1]
