石膏粉的成分和種類分析

來源：http://www.wavc.cn 日期：2023-06-16 發布人：

石膏粉的主要成分是含水的硫酸鈣，大部分都呈白色的透明晶體，因有無結晶水分為“軟石膏”和“硬石膏”。

The main component of gypsum powder is hydrated calcium sulfate, most of which are white transparent crystals. Because of the presence or absence of crystal water, they are "anhydrite" and "Anhydrite".

作為一種墻面基層處理材料，石膏粉又叫膩子粉，主要用來砌墻體，勾縫，墻面找平等。同時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，特種水泥生產中用作復合礦化劑等。

As a wall base treatment material, gypsum powder, also known as putty powder, is mainly used for wall masonry, pointing, and wall leveling. At the same time, 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.

理論組成(wB%)：CaO 32.5，SO3 46.6，H2O+ 20.9。成分變化不大。常有粘土、有機質等機械混入物。有時含SiO2、Al2O3、Fe2O3、MgO、Na2O、CO2、Cl等雜質。

Theoretical composition (wB%): CaO 32.5, SO3 46.6, H2O+20.9. The composition changes little. There are often mechanical mixtures such as clay and organic matter. Sometimes it contains impurities such as SiO2, Al2O3, Fe2O3, MgO, Na2O, CO2, Cl, etc.

生石膏粉的成分

Composition of raw gypsum powder

生石膏為二水硫酸鈣（Ca〔SO4〕·2H2O），又稱二水石膏、水石膏或軟石膏，理論成分CaO32.6%，SO346.5%，H2O+20.9%，單斜晶系，晶體為板狀，通常呈致密塊狀或纖維狀，白色或灰、紅、褐色，玻璃或絲絹光澤，摩氏硬度為2，密度2.3g/cm3；

Raw gypsum is calcium sulfate dihydrate (Ca [SO4] · 2H2O), also known as gypsum dihydrate, hydrogypsum or anhydrite, with theoretical composition of CaO32.6%, SO346.5%, H2O+20.9%, Monoclinic crystal system, crystal is plate shaped, usually dense block or fiber shaped, white or gray, red, brown, glass or silk luster, Mohs hardness of 2, density of 2.3g/cm3;

硬石膏粉的成分

Composition of Anhydrite powder

硬石膏為無水硫酸鈣（Ca〔SO4〕），理論成分CaO41.2%，SO358.8%，斜方晶系，晶體為板狀，通常呈致密塊狀或粒狀，白、灰白色，玻璃光澤，摩氏硬度為3～3.5，密度2.8～3.0g/cm3。兩種石膏常伴生產出，在一定的地質作用下又可互相轉化。

Anhydrite is anhydrous calcium sulfate (Ca [SO4. Two types of gypsum are often produced together and can be transformed into each other under certain geological conditions.
