濟南石膏粉的是用什么原料？

來源：http://www.wavc.cn 日期：2020-12-15 發布人：

生產石膏的原料主要為含硫酸鈣的天然石膏（又稱生石膏）或含硫酸鈣的化工副產品和廢渣，化學式為CaSO。．2H20，也稱二水石膏。常用天然二水石膏制備建來筑石膏。將天然二水石膏在于燥條件下加熱至107—170。C，脫去部分水分即得熟石膏（也稱半水石膏），這就是建筑石膏。

The raw materials of gypsum production are mainly natural gypsum containing calcium sulfate (also known as raw gypsum) or chemical byproducts and waste residue containing calcium sulfate. The chemical formula is CaSO. 2h20, also known as dihydrate gypsum. Natural dihydrate gypsum is often used to prepare gypsum. Natural dihydrate gypsum was heated to 107-170 under dry condition. C. Take off part of the water to get anhydrite (also known as hemihydrate gypsum), which is building gypsum.

目前應用較多的是在建筑石膏中摻人各種填料加工制成各種石膏制品（源如紙面石膏板、纖維石膏板、石膏空心板、石膏裝飾板、石膏砌塊、石膏吊頂等），用于建筑物的內隔墻、墻面和篷頂的裝飾裝修等。

At present, it is widely used to make various kinds of gypsum products (such as paper gypsum board, fiber gypsum board, gypsum hollow board, gypsum decorative board, gypsum block, gypsum ceiling, etc.) by mixing various fillers into the building gypsum, which is used for the decoration and decoration of internal partition wall, wall and roof of buildings.

石膏板具有長期徐變的性質，在潮濕的環境中更為嚴重，且建筑石百膏自身強度較低，又因其呈微酸性，不能配加強鋼筋，故不宜用于承重結構度。為進一步改善石膏的耐水性以擴大其應用范圍，可摻入水泥、粒化高爐礦渣、石灰、粉煤灰或有機防水劑，也可在石膏板表面采用耐水護面紙或防水高分子材料，采取面層防水保護等技術措施。

Gypsum board has the property of long-term creep, which is more serious in humid environment. Moreover, the strength of building stone paste is low. Because it is slightly acidic, it can not be equipped with reinforced steel, so it is not suitable for bearing structure. In order to further improve the water resistance of gypsum and expand its application range, cement, granulated blast furnace slag, lime, fly ash or organic waterproof agent can be added. Water resistant face protection paper or waterproof polymer material can be used on the surface of gypsum board, and the surface waterproof protection measures are taken.
