In the production of gypsum products, hemihydrate gypsum needs less water than common gypsum and has higher density and strength. The steam distilled from the saturated steam in the autoclave is usually semi hydrate gypsum, also known as high-strength gypsum powder; the result is semi hydrate gypsum, also known as building gypsum, which is produced in the pot or rotary kiln. Chemical gypsum is an industrial by-product, which has the same characteristics as natural gypsum and does not need much processing. The slurry weight of hemihydrate gypsum is mixed with water to form a new dihydrate gypsum, which solidifies and hardens rapidly in the drying process to obtain strength, but softens when encountering water.

　　脫硫石膏粉是一種很常見的石膏粉，實際上是指兩種硫酸鈣結晶水，一般作為單獨的晶體顆粒。脫硫后的石膏粉成分與天然石膏基本相同，但純度和細度較高。那么脫硫后的石膏粉有什么作用呢?

　　Desulfurization gypsum powder is a kind of very common gypsum powder, actually refers to two kinds of calcium sulfate crystal water, generally as a separate crystal particle. The composition of gypsum powder after desulfurization is basically the same as that of natural gypsum, but its purity and fineness are higher. So what is the function of gypsum powder after desulfurization?

　　脫硫石膏粉具有廣泛的用途。在質量要求不高的情況下，可作為建筑材料和板材使用。一般來說，在建筑行業中脫硫石膏粉經常用作水泥緩凝劑、石膏粉、石膏塊等。在實際施工過程中，必須在硅酸鹽水泥中加入脫硫石膏粉，才能更好地控制水泥的凝結時間。目前國內水泥用量很大，因此脫水石膏粉的應用也很多。

　　Desulfurization gypsum powder has a wide range of uses. In the case of low quality requirements, it can be used as building materials and plates. Generally speaking, desulfurization gypsum powder is often used as cement retarder, gypsum powder, gypsum block and so on in the construction industry. In the actual construction process, desulfurized gypsum powder must be added to Portland cement to better control the setting time of cement. At present, a large amount of cement is used in China, so there are many applications of dehydrated gypsum powder.

　　生產石膏的原料主要是含硫酸鈣的天然石膏(又稱原石膏塊)或含硫酸鈣的化學副產品和廢渣，如磷石膏、氟石膏、硼石膏。化學式是Caso4.2H2O，也被稱為二水石膏。天然二水石膏在不同溫度下煅燒可得到不同種類的食用石膏粉和工業石膏。如建筑石膏粉在107 ~ 170℃干燥條件下可加熱成天然二水石膏。

　　The raw materials for gypsum production are mainly natural gypsum containing calcium sulfate (also known as original gypsum block) or chemical by-products and waste residues containing calcium sulfate, such as phosphogypsum, fluorogypsum and boron gypsum. The chemical formula is caso4.2h2o, also known as dihydrate gypsum. Different kinds of edible gypsum powder and industrial gypsum can be obtained by calcining natural dihydrate gypsum at different temperatures. For example, the building gypsum powder can be heated to natural dihydrate gypsum under the dry condition of 107 ~ 170 ℃.
