Because the keel is made of wood, attention must be paid to fire prevention. The standard practice is to evenly apply fireproof coating on the surface of the keel, wait for the entire keel to turn white, and then nail it on the wall to ensure that the area in contact with the wall is also coated with fireproof coating.After the fireproof treatment is completed on the surface of the keel, the assembly can begin. The workers will use a nail gun to fix the joint of the two keels at an angle of 45 degrees.

If the flue gas desulfurization gypsum and coal powder from power plants are not treated in a timely and reasonable manner, a large area of land will be utilized, and even unnecessary secondary pollution will be brought to the environment. Desulfurization gypsum from power plants has the characteristics of high taste and small particles. However, with the widespread application of gypsum method and limestone/wet lime in thermal power plants in China, the production of desulfurization gypsum has rapidly increased due to its by-products.

Add foaming agent to the storage tank. When in use, the foaming agent and moisture are respectively sent to the foaming device by the metering pump, and compressed air is introduced to produce stable foam, which is sent to the vertical mixer.After the adhesive is prepared in the tank, it is fed into the spray ports on both sides of the forming station, and the adhesive tape is sprayed onto both sides of the paper gypsum board.

Gypsum board production line Drying sectionThe paper gypsum board is fed into each layer of the 12 layer dryer by a bridge distribution machine according to the program. The dryer is divided into two zones, using hot steam as the heat source. While the hot air paper gypsum board slowly moves forward in the dryer, it continuously exchanges heat with the longitudinally flowing hot air. The board absorbs heat, and the temperature rises. The free water in the board slowly evaporates, but it does not damage the crystalline water of the dihydrate gypsum.

Properties of Gypsum Board from gypsum board machine:1. Gypsum Is Fire-Resistant: Gypsum boards are fire resistant and safeguard the structure from fire threats by preventing the fire from spreading further. Due to chemically bound water in the gypsum, it possesses a fire-resistant quality. When gypsum boards are exposed to fire, the water contained within the gypsum evaporates, forming a protective layer.2. Thermal Properties of Gypsum: Gypsum can regulate variables such as humidity and temperature in the home.
