Product Description

Gypsum powder, natural gypsum powder, calcined natural gypsum powder

The main component of natural gypsum is the hydrate of calcium sulfate (CaSO4), specifically CaSO4·2H2O.

Natural gypsum is a monoclinic crystalline mineral, widely distributed in nature, with a white, colorless or yellow-red appearance when containing impurities, and glass, silk or pearl luster. Its crystal forms are diverse, including plate, fiber, block or fine grain. The density of gypsum is about 2.31 ~ 2.33, and the hardness is lower, which is 2.

Gypsum is widely used in construction, industry, medical and other fields. In the field of construction, gypsum can be used to make gypsum board, gypsum building products, etc. In industry, gypsum can be used as cement retarder, paint filler, etc. On the medical side, plaster is mainly used for external fixation of fractures.

In addition, gypsum also has excellent sound insulation, heat insulation and fire resistance properties due to its microporous structure and heat dewatering.

It is worth noting that gypsum can be divided into two kinds of dihydrate gypsum and anhydrous gypsum according to whether it contains crystal water, of which dihydrate gypsum is more common. At the same time, there is also a mineral called anhydrite, its main component is calcium sulfate without crystal water (CaSO4), but its properties are different from gypsum, generally not used for medicinal purposes.
Gypsum powder is a natural product found in deposits throughout Egypt. It begins as a soft, white mineral rock and is processed to make a dry powder. Naturally occurring gypsum is composed of calcium, sulfur, oxygen and hydrogen. Gypsum bonds easily with water and is usually found in its natural state as hydrated calcium sulfate, with a chemical formula of CaSO4.2H20.
Gypsum powder is mainly used in building materials.
Nearly all modern homes and buildings use gypsum in the form of wall board, also known as gypsum board, drywall or sheet rock.
Gypsum powder is also added to cement and paints used in building construction and finishing. In cement and concrete mixes, gypsum helps to increase the time it takes for concrete and cement to dry and harden, resulting in a more stable structure. In paint, gypsum powder is used a filler to adhere to the pigments and improve the paint's texture..
