脫硫石膏粉、天然石膏、磷石膏的相同及不同之處！

一、4種石膏粉的相同點

1、 Similarities of 4 types of gypsum powder

這幾種石膏粉大多有氧化鈣、三氧化二硫、氧化鎂、氧化鉀等成分組成。另外，石膏粉與天然石膏粉的主要礦物相、轉(zhuǎn)化后的形態(tài)、7種變體物化性能皆相同；水化動力學(xué)和凝結(jié)特征也基本相同。而脫硫石膏又與天然石膏相同，都無放射性，也不危害健康。

These gypsum powders are mostly composed of calcium oxide, sulfur trioxide, magnesium oxide, potassium oxide, and other components. In addition, the main mineral phases, transformed forms, and physical and chemical properties of gypsum powder and natural gypsum powder are the same; The hydration kinetics and condensation characteristics are also basically the same. And desulfurization gypsum, like natural gypsum, is non radioactive and does not pose a health hazard.

二、4種石膏粉的不同點

2、 Differences in 4 types of gypsum powder

1、脫硫石膏粉和磷石膏粉的區(qū)別

這兩種石膏粉中，三氧化硫含量比較多，占據(jù)41%。其次，占比含量從多到少就是氧化鈣、氧化鎂、氧化鋁、三氧化二鐵了。不過磷石膏粉中不含氧化鈉、氧化鉀。

Among these two types of gypsum powder, the content of sulfur trioxide is relatively high, accounting for 41%. Secondly, the proportion of calcium oxide, magnesium oxide, aluminum oxide, and iron oxide ranges from high to low. However, phosphogypsum powder does not contain sodium oxide or potassium oxide.

2、脫硫石膏粉和天然石膏粉的區(qū)別

2. The difference between desulfurization gypsum powder and natural gypsum powder

石膏粉生產(chǎn)廠家表示，脫硫石膏粉中含量較多的是三氧化硫，而天然石膏粉中氧化鉀的含量比較多。另外，兩者原始物理狀態(tài)不一樣。前者是以單獨的結(jié)晶顆粒存在的，而后者則是粘合在一起的塊狀。其次，在雜質(zhì)成分上也有所差異，如此，在脫水特性、易磨性，煅燒后的熟石膏粉在力學(xué)性能等宏觀特征上都有所不同。

The gypsum powder manufacturer stated that the desulfurization gypsum powder contains more sulfur trioxide, while natural gypsum powder contains more potassium oxide. In addition, the original physical state of the two is different. The former exists as individual crystalline particles, while the latter is a cohesive block. Secondly, there are also differences in impurity composition, resulting in differences in dehydration characteristics, grindability, and macroscopic characteristics such as mechanical properties of calcined gypsum powder.

3、脫硫石膏粉與半水石膏的區(qū)別

3. The difference between desulfurization gypsum powder and hemihydrate gypsum

前者是煙囪脫硫的副產(chǎn)品，而半水石膏是石膏粉在不同溫度下脫水形成的半水石膏，根據(jù)不同的煅燒方式可以分為α半水石膏和β半水石膏。

The former is a by-product of chimney desulfurization, while hemihydrate gypsum is a hemihydrate gypsum formed by dehydration of gypsum powder at different temperatures. According to different calcination methods, it can be divided into α Hemihydrate gypsum and β Hemihydrate gypsum.
