用途：

Purpose:

建筑领域：石膏粉用于建筑装修中的石膏板制作，具有轻、耐火、隔声、隔热等特点。也用于墙体找平、阴阳角调直等基层处理，以及制作石膏水泥等。

In the field of architecture, gypsum powder is used for the production of gypsum boards in building decoration, which has the characteristics of light weight, fire resistance, sound insulation, and thermal insulation. It is also used for base treatment such as wall leveling, internal and external corner straightening, as well as for making gypsum cement, etc.

化工领域：石膏粉用于生产硫酸、硫酸铵，以及作为密封胶的填充剂或用于配置无机胶黏剂。

In the field of chemical engineering, gypsum powder is used for the production of sulfuric acid, ammonium sulfate, as a filler for sealants, or for the preparation of inorganic adhesives.

农业：石膏粉用于改良土壤，调节酸碱度，适用于盐碱地、红土地等土壤的改良，以及作为食用菌栽培上的钙、硫复合矿物肥料。

Agriculture: Gypsum powder is used to improve soil, regulate acidity and alkalinity, and is suitable for improving soils such as saline alkali and red soil. It is also used as a calcium and sulfur composite mineral fertilizer for edible mushroom cultivation.

食品加工：食用级石膏粉用作营养增补剂（钙质强化）、凝固剂、酵母食料、面团调节剂、螯合剂，还用作番茄、土豆罐头中的组织强化剂。

Food processing: Edible grade gypsum powder is used as a nutritional supplement (calcium fortifier), coagulant, yeast feed, dough conditioner, chelating agent, and also as a tissue fortifier in canned tomatoes and potatoes.

医疗领域：石膏粉用于护理和外科治疗，支撑和固定患者的骨骼和软组织，减轻病人的疼痛.

Medical field: Gypsum powder is used for nursing and surgical treatment, supporting and fixing patients' bones and soft tissues, and reducing patients' pain

特性：

characteristic:

物理特性：石膏粉的莫氏硬度为1.5~2，微溶于水，溶于酸、铵盐、硫代硫酸钠和甘油。

Physical properties: The Mohs hardness of gypsum powder is 1.5~2, slightly soluble in water, soluble in acids, ammonium salts, sodium thiosulfate, and glycerol.

热稳定性：加热至150℃时失去1.5H2O而成半水物(熟石膏)，继续加热至163℃失去全部结晶水变成无水物。

Thermal stability: When heated to 150 ℃, it loses 1.5H2O and becomes a semi hydrated substance (gypsum), and when further heated to 163 ℃, it loses all crystalline water and becomes anhydrous.

隔音隔热防火性能：石膏及其制品的微孔结构和加热脱水性，使之具优良的隔音、隔热和防火性能。

Sound insulation, heat insulation, and fire resistance performance: The microporous structure and heating dehydration properties of gypsum and its products endow them with excellent sound insulation, heat insulation, and fire resistance performance.

安全性：石膏粉无毒，使用时需注意防潮、防湿，并应贮存于干燥、洁净的库房中。

Safety: Gypsum powder is non-toxic. When using it, attention should be paid to moisture and humidity prevention, and it should be stored in a dry and clean warehouse.

以上是石膏粉的一些基本知识，其应用范围广泛，从建筑到化工，再到农业和食品加工等多个领域都有涉及。

The above are some basic knowledge of gypsum powder, which has a wide range of applications from construction to chemical industry, as well as agriculture and food processing.
