在房子的裝修中會用到一種裝飾材料——濟南石膏粉，很少有業主會注意到這樣一種材料，其實石膏粉是一種裝修墻面找平材料，可以算得上是裝修過程中必不可少的裝修材料。那么，石膏粉有哪些重要作用？

Jinan gypsum powder is a decorative material used in the decoration of houses, and few homeowners pay attention to such a material. In fact, gypsum powder is a leveling material for wall decoration, which can be considered an essential decoration material in the decoration process. So, what are the important functions of gypsum powder?

石膏粉是五大凝膠型的裝飾材料之一，廣泛用于建筑、建材、工業的模具和藝術的模型、化學工業及農業、食品加工和醫藥美容等眾多產業和應用領域，是一種非常重要的工業原材料，通常為白色、無色，有時可能會因含雜質而變成灰、淺黃、淺褐等不同的顏色。

Gypsum powder is one of the five gel type decorative materials. It is widely used in architecture, building materials, industrial molds and artistic models, chemical industry and agriculture, food processing, medicine and beauty and many other industries and application fields. It is a very important industrial raw material, usually white and colorless, and sometimes may become gray, light yellow, light brown and other different colors due to impurities.

石膏粉的作用：

The function of gypsum powder:

1、墻體找平：

1. Wall leveling:

在裝修過程中石膏粉一般的是用來做墻面基層處理的，比如填平縫隙、陰陽角調直、毛坯房的墻面遍使用膩子找平等。石膏的粘接度好，比較不容易有產生出脫落的現象，在用來進行家中的墻面找平時，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。

During the decoration process, gypsum powder is generally used for wall base treatment, such as filling gaps, straightening internal and external corners, and leveling the walls of rough rooms with putty for the first time. Gypsum has good adhesion and is less prone to detachment. When used for leveling walls in homes, gypsum powder is generally not directly used, and talcum powder is also added inside, otherwise construction may be inconvenient.

2、制作石膏水泥：

2. Production of gypsum cement:

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 material, which is suitable for the reinforcement of soft soil foundation, wall painting, mechanical model, tunnel support and production of fiber pressure board.

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，特種水泥生產中用作復合礦化劑等。

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.

石膏粉生產工藝是將天然二水石膏礦石(生石膏)或工業副產石膏(脫硫石膏、磷石膏等)通過專用磨粉機磨細并經過一定溫度加熱煅燒，使二水石膏脫水分解,得到的以β半水石膏(CaSO4?1/2H2O)為主要成分的產品，即為建筑石膏(通為熟石膏)。

The production process of gypsum powder is to grind natural dihydrate gypsum ore (raw gypsum) or industrial by-product gypsum (desulfurized gypsum, phosphogypsum, etc.) through a special grinder and calcine it at a certain temperature to dehydrate and decompose the dihydrate gypsum β The product with hemihydrate gypsum (CaSO4? 1/2H2O) as the main component is building gypsum (commonly known as gypsum).

概括來說，石膏粉生產工藝主要有以下幾種：

In summary, there are several main production processes for gypsum powder:

(1)煅燒塊石膏，然后再粉碎。

(1) Calcine gypsum blocks and then crush them.

這種方法的優點是設備簡單,燒后的塊石膏粉碎效率高。缺點是石膏煅燒不均勻,容易造成局部死燒和生燒現象,同時也容易混入煤灰等雜質。

The advantages of this method are simple equipment and high efficiency in crushing the burnt gypsum blocks. The disadvantage is that the gypsum calcination is uneven, which can easily cause local dead burning and raw burning phenomena, and it is also easy to mix impurities such as coal ash.

(2)煅燒已粉碎的石膏粉。

(2) Calcined crushed gypsum powder.

這種方法優點是粉磨過的顆粒燒得比較完全,質量較高,缺點是生石膏的水分大,粉碎效率低,炒石膏時攪拌不易均勻。

The advantage of this method is that the ground particles are completely burned and of high quality. The disadvantage is that the raw gypsum has a high moisture content, low crushing efficiency, and it is not easy to stir evenly when frying the gypsum.

(3)生石膏的粉磨和煅燒同時進行。

(3) The grinding and calcination of raw gypsum are carried out simultaneously.

這種方法的優點是產量大,炒膏效率高,所得快速炒制的熟石膏凝結快,強度低,但設備復雜。

The advantages of this method are high yield, high frying efficiency, quick solidification of the obtained gypsum, low strength, but complex equipment.

(4)先將石膏粉碎成細顆粒砂狀,然后炒制，炒制以后再進行粉碎和篩分。

(4) First, crush the gypsum into fine sand particles, then stir fry it, and then crush and screen it.

這種方法在國內陶瓷行業中仍應用較廣。

This method is still widely used in the domestic ceramic industry.

(5)壓蒸法炒膏。

(5) Stir fry paste using pressure steaming method.

不論何種方法,熟石膏粉的細度一般都要求80——120目篩的余量不超過0.5%。

Regardless of the method, the fineness of gypsum powder generally requires a margin of no more than 0.5% on the 80-120 mesh sieve.
