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、墻體找平

1. Wall leveling

在裝修中石膏粉一般用來(lái)做基層處理的，比如填平縫隙、陰陽(yáng)角調(diào)直、毛坯房墻面一遍膩?zhàn)诱移降取Ｊ嗟恼辰佣群茫灰桩a(chǎn)生脫落現(xiàn)象，在用來(lái)進(jìn)行墻面找平時(shí)，一般并不是直接使用石膏粉的，里面也會(huì)加入滑石粉，否則施工會(huì)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

摻加適量的激發(fā)劑可生產(chǎn)硬石膏水泥或膠凝材料，適用于軟土地基的加固，墻體粉刷，機(jī)械模型，坑道支護(hù)及生產(chǎn)纖維壓力板等。

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

石膏粉可以作為混凝土膨脹劑、抗裂劑、自流平砂漿的主要原材料，特種水泥生產(chǎn)中用作復(fù)合礦化劑等。

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. 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、粘接力強(qiáng)：

5. Strong adhesion:

粉刷石膏與各種墻體基材(粘土磚、水泥砌塊、加氣混凝土、粉煤灰磚、石膏砌塊、現(xiàn)澆混凝土、頂棚等)都能很好地粘結(jié)，抹灰時(shí)不用刷任何界面劑，直接抹灰，一次成活，抹灰墻面不會(huì)出現(xiàn)空鼓、開(kāi)裂現(xiàn)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、表面裝飾性：

6. Surface decoration:

粉刷石膏墻面細(xì)膩光滑而不起灰，強(qiáng)度高、不收縮，外觀典雅，無(wú)氣味，不返堿，無(wú)裂紋。

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:

當(dāng)粉刷石膏抹面厚度為20mm時(shí)，耐火可達(dá)到2小時(shí)以上。

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