Classification of gypsum board materials:
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.
1. Gypsum board: Gypsum board is a lightweight 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. Water-resistant gypsum board after fire protection treatment can be used for room walls with high humidity, such as the lining of ceramic tiles, metal plates and plastic brick walls in bathrooms, kitchens and bathrooms.
2. Decorative gypsum board: Decorative gypsum board is a board with various patterns and ornamentation made of building gypsum as the main raw material and a small amount of fiber materials, 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 lath is a kind of hollow slab made of building gypsum as the main raw material and adding a proper amount of 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 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. Plant straw gypsum board: Different from ordinary gypsum board, it uses a lot of plant straw and makes full use of local wastes, which not only solves the environmental protection problem, but also increases farmers' economic income, reduces the weight of gypsum board, reduces transportation costs and reduces coal and electricity consumption by 30%-45%, which is in full compliance with relevant national industrial policies.
6. Anchored gypsum board: the second generation gypsum board-Bayer anchored gypsum board.
This product is a new generation of patented gypsum board product which is successfully developed by Bayer according to the actual needs of the project after years of painstaking research and conforms to 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.
Performance analysis of gypsum board;
1, with low energy consumption. The unit energy consumption of gypsum powder used to produce gypsum board is 78% lower than that of cement.
2. Lightweight thermal insulation, using gypsum board as partition wall, the weight is only 1/3 1/4 of brick wall. At the same time, due to the porous structure of gypsum board, its thermal conductivity is 0.30, which is better than that of brick (0.43) and concrete (1.63).
3. It has excellent fireproof performance. Because gypsum releases bound water when heated, its fireproof limit can reach more than 2 hours.
4. The decorative function is good, the gypsum board surface is smooth, and the boards can be firmly bonded together by cementing materials to form a seamless structure, and the architectural decoration effect is good.
5. Good constructability. Gypsum board can be nailed, sawed and glued, and the construction is very convenient. Using it as decoration can get rid of the traditional wet operation and greatly improve the construction efficiency.
6, comfortable living function, because gypsum board has a unique "breathing" performance, it has the ability to adjust indoor humidity and make living comfortable.
7. High production efficiency. And is beneficial to realize large-scale production. Among all kinds of building boards, gypsum board has the highest production efficiency and is convenient for large-scale production.
8. Less investment. Compared with fiber gypsum board, cement foam board and gypsum board, gypsum board production equipment can realize continuous mechanized production, with very high equipment utilization rate and less equipment investment.
