Plastering gypsum is a green and environmentally friendly material that is suitable for new wall interior plastering. In view of some problems in the construction of lightweight wallboards, plastering gypsum is a good supporting material to ensure that the plaster layer is not hollow, The first condition for no cracking. The gypsum slurry easily penetrates into the pores on the wallboard surface, and the volume expands during the hydration process to form tenon and small joints, which increase the bonding strength between the plaster layer and the wallboard.

Use plastering gypsum to solve the defects of poor wallboard strength and wallboard deformation, substandard installation, poor sound insulation and heat preservation performance, avoiding the disadvantages caused by excessive and uneven water content inside the wallboard, and long-term stability of the wall Sex has a good effect. The plastering layer will not appear on the light wall without lateral cracks caused by sliding down the surface of the base layer.

The content of crystal water in plastering gypsum accounts for 20.9% of the entire molecular weight. After plastering on lightweight wall panels, if a fire occurs in a building, the wall can continue as long as the water in the plaster is not completely released and evaporated. The heating time can improve the fire resistance of the wall panel and reduce the damage to the building during a fire. Because plastering plaster has good workability, the plastering layer can be thin or thick (1.5mm～30mm can be used), which has an excellent application effect on the trimming and leveling of lightweight wallboards. Quality wallboard is the first choice for supporting materials in winter construction.

Products must be inspected before leaving the factory.

The inspection items include:

1.Surface plastering plaster: fineness, setting time, flexural strength, compressive strength;

2. Bottom plaster plaster: setting time, flexural strength, compressive strength;

3. Lightweight bottom plastering plaster: setting time, bulk density, flexural strength, compressive strength;

4. Plastering gypsum for insulation layer: setting time, bulk density, compressive strength.

To

Plastering gypsum should be stored indoors. During transportation and storage, it should not be damp and mixed with debris. Different types of plastering gypsum should be stored and transported separately and not mixed.

Plastering gypsum is calculated from the date of production under normal transportation and storage conditions. The storage period is six months for bags and three months for cans.
