1. Wall leveling
In decoration, gypsum powder is generally used for basic treatment, such as filling gaps, straightening the yin and yang angles, and putting putty on the wall of the rough house to find the equality. Gypsum has good adhesion and is not easy to fall off. When it is used for wall leveling, gypsum powder is generally not used directly, and talcum powder is also added in it, otherwise the construction will be inconvenient.
2. Making gypsum cement
Adding appropriate amount of activator can produce anhydrite cement or cementitious material, which is suitable for the reinforcement of soft soil foundation, wall painting, mechanical model, tunnel support and production of fiber pressure plate, etc.
3. Other functions
Gypsum powder can be used as the main raw material of concrete expansion agent, anti-cracking agent, self-leveling mortar, and used as composite mineralizer in the production of special cement.
4. Gypsum powder is also called putty powder. In decoration, gypsum powder is generally used for basic treatment, such as filling gaps, straightening the yin and yang angles, and finding equality with putty on the wall of the rough house. Gypsum has good adhesion and is not easy to fall off. When it is used for wall leveling, gypsum powder is generally not used directly, and talcum powder will also be added in it, otherwise the construction will be inconvenient.
5. Strong adhesion:
Plastered plaster can bond well with various wall substrates (clay bricks, cement blocks, aerated concrete, fly ash bricks, gypsum blocks, cast-in-place concrete, ceilings, etc.) The interface agent can be directly plastered, and it can survive at one time, and the plastered wall will not appear hollow or cracked.
6. Surface decoration:
The plastered gypsum walls are fine and smooth without ash, high strength, no shrinkage, elegant appearance, no odor, no alkali return, no cracks.
7. Fire resistance:
When the thickness of the plastered plaster surface is 20mm, the fire resistance can reach more than 2 hours.
