Gypsum powder: source and production materials
Gypsum powder, as an important building and decorative material, has a wide range of applications in various fields such as architecture, sculpture, ceramics, etc. So, what material is gypsum powder made from?
The main raw material of gypsum powder is natural gypsum, which is a mineral resource widely distributed in nature. Natural gypsum is mainly composed of calcium sulfate, usually accompanied by other minerals such as quartz and feldspar. In the production process of gypsum powder, it is necessary to first extract and crush natural gypsum, then go through processes such as calcination and grinding, and finally produce gypsum powder with moderate fineness.
In addition to natural gypsum, there is also a type of gypsum powder made from industrial by-product gypsum. The industrial by-product gypsum mainly comes from the waste residue generated in industrial production processes such as phosphate fertilizer and desulfurization. After appropriate treatment, this type of gypsum can also be made into gypsum powder, achieving resource recycling.
During the production process of gypsum powder, some auxiliary materials such as reinforcing agents and water reducing agents are also added to improve the physical and construction properties of gypsum powder. The selection and use of these auxiliary materials need to be determined based on specific application scenarios and technical requirements.
In short, gypsum powder is made from natural gypsum or industrial by-product gypsum through a series of processing steps. During the production process, strict control of raw material quality, production process, and equipment conditions can ensure the stable and reliable quality of gypsum powder.
