Is gypsum board environmentally friendly? Gypsum board is a new type of environmentally friendly and energy-saving material that can be recycled. There are not many toxic components in gypsum board. Only the dispersant (it seems to be called naphthalene sulfonic acid) is harmful to the human body. Other components such as boric acid, soap Liquid, water, gypsum powder, starch, raw materials, sucrose, and paper are all common chemical materials.
Environmental performance of gypsum board:
1. Low production energy consumption. The unit production energy consumption of plaster of paris, a cementing material used in the production of gypsum boards, is 78% lower than that of cement.
2. Lightweight insulation, using gypsum board as the 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, which has excellent thermal insulation performance compared with brick (0.43) and concrete (1.63).
3. It has excellent fire resistance. Because gypsum releases combined water when heated, its fire resistance limit can reach more than 2 hours.
4. It has good decorative function. The surface of the gypsum board is smooth, and the boards can be firmly bonded together through cementing material to form a seamless structure, and the building decoration effect is good.
5. Good constructability. The gypsum board can be nailed, sawed, and glued, and is very convenient for construction. Using it for decoration can get rid of the traditional wet work 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, making living comfortable.
7. High production efficiency. It is conducive to realizing large-scale production. Among various building boards, gypsum board has the highest production efficiency and is convenient for large-scale production.
8. Low investment. Compared with fiber gypsum board, cement foam board, and gypsum board, the production equipment of gypsum board can realize continuous mechanized production, the equipment utilization rate is very high, and the equipment investment is low.
