石膏粉有哪些種類

裝修中石膏粉的作用

Function of gypsum powder in decoration

在裝修中石膏粉一般用來做基層處理的，比如填平縫隙、陰陽角調直、毛坯房墻面遍膩子找平等。石膏的粘接度好，不易產生脫落現象，在用來進行墻面找平時，一般并不是直接使用石膏粉的，里面也會加入滑石粉，否則施工會不太方便了。

In decoration, gypsum powder is generally used for base treatment, such as filling gaps, straightening internal and external corners, and leveling the first putty on the wall of rough room. 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 talc powder will also be added, otherwise the construction will be inconvenient.

摻加適量的激發劑可生產硬石膏水泥或膠凝材料，適用于軟土地基的加固，墻體粉刷，機械模型，坑道支護及生產纖維壓力板等。

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

濟南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，特種水泥生產中用作復合礦化劑等。

Jinan gypsum powder can be used as the main raw material of concrete expansion agent, anti cracking agent, self leveling mortar, and composite mineralizer in the production of special cement.

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、現澆混凝土、頂棚等)都能很好地粘結，抹灰時不用刷任何界面劑，直接抹灰，一次成活，抹灰墻面不會出現空鼓、開裂現象。

Plastered gypsum can be well bonded with various wall substrates (clay bricks, cement blocks, aerated concrete, fly ash bricks, gypsum blocks, cast-in-situ concrete, ceilings, etc.). When plastering, it does not need to brush any interface agent, and it can be plastered directly. It can survive at one time, and the plastered wall surface will not appear hollowing and cracking.
