在房子的裝修中會(huì)用到一種裝飾材料——濟(jì)南石膏粉，很少有業(yè)主會(huì)注意到這樣一種材料，其實(shí)石膏粉是一種裝修墻面找平材料，可以算得上是裝修過(guò)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(yè)的模具和藝術(shù)的模型、化學(xué)工業(yè)及農(nóng)業(yè)、食品加工和醫(yī)藥美容等眾多產(chǎn)業(yè)和應(yīng)用領(lǐng)域，是一種非常重要的工業(yè)原材料，通常為白色、無(wú)色，有時(shí)可能會(huì)因含雜質(zhì)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(guò)程中石膏粉一般的是用來(lái)做墻面基層處理的，比如填平縫隙、陰陽(yáng)角調(diào)直、毛坯房的墻面遍使用膩?zhàn)诱移降取Ｊ嗟恼辰佣群茫容^不容易有產(chǎn)生出脫落的現(xiàn)象，在用來(lái)進(jìn)行家中的墻面找平時(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。

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(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 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(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.

石膏粉生產(chǎn)工藝是將天然二水石膏礦石(生石膏)或工業(yè)副產(chǎn)石膏(脫硫石膏、磷石膏等)通過(guò)專用磨粉機(jī)磨細(xì)并經(jīng)過(guò)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(chǎn)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(lái)說(shuō)，石膏粉生產(chǎn)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(yōu)點(diǎn)是設(shè)備簡(jiǎn)單,燒后的塊石膏粉碎效率高。缺點(diǎn)是石膏煅燒不均勻,容易造成局部死燒和生燒現(xiàn)象,同時(shí)也容易混入煤灰等雜質(zhì)。

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(yōu)點(diǎn)是粉磨過(guò)的顆粒燒得比較完全,質(zhì)量較高,缺點(diǎn)是生石膏的水分大,粉碎效率低,炒石膏時(shí)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(shí)進(jìn)行。

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

這種方法的優(yōu)點(diǎn)是產(chǎn)量大,炒膏效率高,所得快速炒制的熟石膏凝結(jié)快,強(qiáng)度低,但設(shè)備復(fù)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(xì)顆粒砂狀,然后炒制，炒制以后再進(jìn)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(guó)內(nèi)陶瓷行業(yè)中仍應(yīng)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(xì)度一般都要求80——120目篩的余量不超過(guò)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.

石膏粉是裝修中常見(jiàn)的一種墻面等基層處理材料，相對(duì)其他材料來(lái)比較容易受到忽略，但有經(jīng)驗(yàn)的裝修師傅會(huì)告訴你石膏粉在墻面裝修上非常重要。您有需求就來(lái)我們網(wǎng)站http://www.netjobs.cc咨詢了解吧！
