比較常見的石膏粉有天然石膏婚温、脫硫石膏粉萎战、半水石膏、磷石膏4種揉阎。那么這4種石膏粉有哪些相同及不同之處呢庄撮？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余黎、 Similarities between 4 types of gypsum powder

這4種石膏粉其原料成分大多有SO?弛镣、Al?O?、Fe?O?才擒、CaO钩裆、MgO和K?O等成分。另外善瞧，這幾種石膏粉首要礦產(chǎn)相图盖、轉(zhuǎn)化后的五種形態(tài)毕蕉、七種變體物化功能相同；水化動力學(xué)和凝集特征根本相同企著；而且均沒有放射性乙笛，不會損壞人體健康。

These four types of gypsum powder mostly contain SO Al? O?冒溜、 Fe? O?刽室、 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饶辆、 Differences between the 4 types of gypsum powder

1酪律、原始物理狀態(tài)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(jié)晶顆粒存在翻默。另外脫硫石膏與石膏之間缸沃，易磨性相差比較大。比如天然石膏經(jīng)過粉磨后的粗顆粒大多是雜質(zhì)修械；而脫硫石膏顆粒比較多的則為石膏趾牧，細顆粒多為雜質(zhì)，特征與天然石膏相反肯污。

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翘单、含量不同，雜質(zhì)不同

2. Different contents and impurities

天然石膏中仇箱，含量較多的是K?O县恕，約占44%左右；脫硫石膏粉中含量較多的是Al?O?剂桥，約占45%；磷石膏粉中含量較多的是SO?属提，約占41%权逗。另外，脫硫石膏粉與天然石膏粉在雜質(zhì)成分上也有所差異冤议，進而導(dǎo)致脫水特性僵馒、易磨性，煅燒之后的熟石膏粉在流變功能上皆有所不同粪畔。

What is the higher content of K in natural gypsum? O. About 44%; Is Al the most abundant component in desulfurization gypsum powder? O?绸秸， 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(guān)于石膏粉施工墻面會出現(xiàn)開裂問題，這是因為材料不合格支际，開槽修補匠似、工藝不到位等因素導(dǎo)致⌒芳蓿可以通過控制原材料質(zhì)量暗沉，使用更加成熟品牌的石膏砂漿英谢，且材料要經(jīng)抽樣、送檢里淡、現(xiàn)場打樣合格后才能使用刃伞，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(yīng)嚴格按照要求進行施工谎跨，單次批檔厚度控制要合適钥嫌，室內(nèi)風(fēng)不宜太大以免導(dǎo)致石膏表層水分蒸發(fā)過快。如何修補呢男杈？粉刷層未干時在其表面薄薄滿批一層即可恢復(fù)丈屹；粉刷層已干時，灑水濕潤后再批势就，不會再出現(xiàn)裂縫泉瞻。

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.
