4種石膏粉的相同及不同之處

來源：http://www.wavc.cn 日期：2023-04-11 發布人：

比較常見的石膏粉有天然石膏、脫硫石膏粉、半水石膏、磷石膏4種。那么這4種石膏粉有哪些相同及不同之處呢？下面濟南石膏粉廠家為您分析一番：

The common gypsum powder includes natural gypsum, desulfurized gypsum powder, hemihydrate gypsum and phosphogypsum. So what are the similarities and differences between these four types of gypsum powder? Below, Jinan gypsum powder manufacturer will analyze for you:

一、4種石膏粉的相同之處

1、 Similarities between 4 types of gypsum powder

這4種石膏粉其原料成分大多有SO?、Al?O?、Fe?O?、CaO、MgO和K?O等成分。另外，這幾種石膏粉首要礦產相、轉化后的五種形態、七種變體物化功能相同；水化動力學和凝集特征根本相同；而且均沒有放射性，不會損壞人體健康。

These four types of gypsum powder mostly contain SO Al? O?、 Fe? O?、 CaO, MgO, and K? Ingredients such as O. In addition, these gypsum powders have the same primary mineral phase, five transformed forms, and seven variants in terms of physicochemical functions; The hydration kinetics and coagulation characteristics are fundamentally the same; And there is no radiation, which will not damage human health.

二、4種石膏粉的不同之處

2、 Differences between the 4 types of gypsum powder

1、原始物理狀態不同

1. The original physical state is different

天然石膏是粘合在一起的塊狀；但脫硫石膏是以單獨的結晶顆粒存在。另外脫硫石膏與石膏之間，易磨性相差比較大。比如天然石膏經過粉磨后的粗顆粒大多是雜質；而脫硫石膏顆粒比較多的則為石膏，細顆粒多為雜質，特征與天然石膏相反。

Natural gypsum is a block that is bonded together; But desulfurization gypsum exists as separate crystalline particles. In addition, there is a significant difference in grindability between desulfurization gypsum and gypsum. For example, the coarse particles of natural gypsum after grinding are mostly impurities; The gypsum with more desulfurization particles is gypsum, and the fine particles are mostly impurities, with opposite characteristics to natural gypsum.

2、含量不同，雜質不同

2. Different contents and impurities

天然石膏中，含量較多的是K?O，約占44%左右；脫硫石膏粉中含量較多的是Al?O?，約占45%；磷石膏粉中含量較多的是SO?，約占41%。另外，脫硫石膏粉與天然石膏粉在雜質成分上也有所差異，進而導致脫水特性、易磨性，煅燒之后的熟石膏粉在流變功能上皆有所不同。

What is the higher content of K in natural gypsum? O. About 44%; Is Al the most abundant component in desulfurization gypsum powder? O?， About 45%; The content of SO? In phosphogypsum powder is high?, About 41%. In addition, there are differences in impurity composition between desulfurization gypsum powder and natural gypsum powder, which leads to dehydration characteristics, grindability, and differences in rheological function of calcined gypsum powder.

此外要注意關于石膏粉施工墻面會出現開裂問題，這是因為材料不合格，開槽修補、工藝不到位等因素導致。可以通過控制原材料質量，使用更加成熟品牌的石膏砂漿，且材料要經抽樣、送檢、現場打樣合格后才能使用，不同品種石膏不得混用。

In addition, attention should be paid to the cracking problem of gypsum powder construction walls, which is caused by factors such as unqualified materials, slot repair, and inadequate workmanship. By controlling the quality of raw materials, more mature brands of gypsum mortar can be used, and the materials can only be used after passing sampling, inspection, and on-site sampling. Different types of gypsum cannot be mixed.

在施工時應嚴格按照要求進行施工，單次批檔厚度控制要合適，室內風不宜太大以免導致石膏表層水分蒸發過快。如何修補呢？粉刷層未干時在其表面薄薄滿批一層即可恢復；粉刷層已干時，灑水濕潤后再批，不會再出現裂縫。

During construction, the requirements should be strictly followed, and the thickness of each batch should be controlled appropriately. The indoor air should not be too strong to avoid rapid evaporation of moisture on the gypsum surface. How to fix it? When the paint layer is not dry, it can be restored by applying a thin and full layer on its surface; When the paint layer is dry, spray water to moisten it before applying, and there will be no more cracks.

以上就是4種石膏粉的相同及不同之處的介紹，希望能夠幫助到您，您對此還有什么問題就來我們網站http://www.wavc.cn咨詢了解吧！
