在房子的装修中会用到一种装饰材料——济南石膏粉，很少有业主会注意到这样一种材料，其实石膏粉是一种装修墙面找平材料，可以算得上是装修过程中必不可少的装修材料。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?

石膏粉是五大凝胶型的装饰材料之一，广泛用于建筑、建材、工业的模具和艺术的模型、化学工业及农业、食品加工和医药美容等众多产业和应用领域，是一种非常重要的工业原材料，通常为白色、无色，有时可能会因含杂质而变成灰、浅黄、浅褐等不同的颜色。

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、墙体找平：

1. Wall leveling:

在装修过程中石膏粉一般的是用来做墙面基层处理的，比如填平缝隙、阴阳角调直、毛坯房的墙面遍使用腻子找平等。石膏的粘接度好，比较不容易有产生出脱落的现象，在用来进行家中的墙面找平时，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。

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:

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 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.

石膏粉生产工艺是将天然二水石膏矿石(生石膏)或工业副产石膏(脱硫石膏、磷石膏等)通过专用磨粉机磨细并经过一定温度加热煅烧，使二水石膏脱水分解,得到的以β半水石膏(CaSO4?1/2H2O)为主要成分的产品，即为建筑石膏(通为熟石膏)。

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).

概括来说，石膏粉生产工艺主要有以下几种：

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

(1)煅烧块石膏，然后再粉碎。

(1) Calcine gypsum blocks and then crush them.

这种方法的优点是设备简单,烧后的块石膏粉碎效率高。缺点是石膏煅烧不均匀,容易造成局部死烧和生烧现象,同时也容易混入煤灰等杂质。

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)煅烧已粉碎的石膏粉。

(2) Calcined crushed gypsum powder.

这种方法优点是粉磨过的颗粒烧得比较完全,质量较高,缺点是生石膏的水分大,粉碎效率低,炒石膏时搅拌不易均匀。

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)生石膏的粉磨和煅烧同时进行。

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

这种方法的优点是产量大,炒膏效率高,所得快速炒制的熟石膏凝结快,强度低,但设备复杂。

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

(4)先将石膏粉碎成细颗粒砂状,然后炒制，炒制以后再进行粉碎和筛分。

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

这种方法在国内陶瓷行业中仍应用较广。

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

(5)压蒸法炒膏。

(5) Stir fry paste using pressure steaming method.

不论何种方法,熟石膏粉的细度一般都要求80——120目筛的余量不超过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.
