Gypsum powder has a wide range of uses in the construction industry, mainly for indoor wall blocks, gypsum boards, interior decoration, and wall plastering. Additionally, gypsum is mainly used for wall leveling, quick drying gypsum joint filling, line blocking, and local ground gypsum leveling. Colored gypsum powder can also serve as a simple decoration for walls, with a very low cost.

1、墙体找平

1. Wall leveling

在装修中石膏粉一般用来做基层处理的，比如填平缝隙、阴阳角调直、毛坯房墙面一遍腻子找平等。石膏的粘接度好，不易产生脱落现象，在用来进行墙面找平时，一般并不是直接使用石膏粉的，里面也会加入滑石粉，否则施工会不太方便了。

Gypsum powder is generally used for grassroots treatment in decoration, such as filling gaps, straightening internal and external corners, and leveling the walls of rough rooms with a layer of putty. Gypsum has good adhesion and is not prone to detachment. When used for wall leveling, gypsum powder is generally not directly used, and talcum powder is also added inside, otherwise construction will be inconvenient.

2、制作石膏水泥

2. Making gypsum cement

掺加适量的激发剂可生产硬石膏水泥或胶凝材料，适用于软土地基的加固，墙体粉刷，机械模型，坑道支护及生产纤维压力板等。

Adding an appropriate amount of activator can produce anhydrite cement or cementitious materials, suitable for reinforcement of soft soil foundations, wall painting, mechanical models, tunnel support, and production of fiber pressure boards.

3、其他作用

3. Other functions

石膏粉可以作为混凝土膨胀剂、抗裂剂、自流平砂浆的主要原材料，特种水泥生产中用作复合矿化剂等。

Gypsum powder can be used as the main raw material for concrete expansion agent, crack resistance agent, and self-leveling mortar, and as a composite mineralizer in the production of special cement.

4、石膏粉又叫腻子粉，在装修中石膏粉一般用来做基层处理的，比如填平缝隙、阴阳角调直、毛坯房墙面一遍腻子找平等。石膏的粘接度好，不易产生脱落现象，在用来进行墙面找平时，一般并不是直接使用石膏粉的，里面也会加入滑石粉，否则施工会不太方便了。

4. Gypsum powder, also known as putty powder, is generally used for grassroots treatment in decoration, such as filling gaps, straightening internal and external corners, and leveling the walls of rough rooms with putty once. Gypsum has good adhesion and is not prone to detachment. When used for wall leveling, gypsum powder is generally not directly used, and talcum powder is also added inside, otherwise construction will be inconvenient.

5、粘接力强：

5. Strong adhesion:

粉刷石膏与各种墙体基材(粘土砖、水泥砌块、加气混凝土、粉煤灰砖、石膏砌块、现浇混凝土、顶棚等)都能很好地粘结，抹灰时不用刷任何界面剂，直接抹灰，一次成活，抹灰墙面不会出现空鼓、开裂现象。

Plastering gypsum can bond well with various wall substrates (such as clay bricks, cement blocks, aerated concrete, fly ash bricks, gypsum blocks, cast-in-place concrete, ceilings, etc.). When plastering, there is no need to brush any interface agent, and it can be directly plastered. Once completed, the plastered wall will not show hollowing or cracking.

6、表面装饰性：

6. Surface decoration:

粉刷石膏墙面细腻光滑而不起灰，强度高、不收缩，外观典雅，无气味，不返碱，无裂纹。

The plastered gypsum wall surface is delicate and smooth without dust, with high strength, no shrinkage, elegant appearance, no odor, no alkali, and no cracks.

7、防火性能：

7. Fire performance:

当粉刷石膏抹面厚度为20mm时，耐火可达到2小时以上。

When the thickness of the plaster is 20mm, the fire resistance can reach more than 2 hours.
