Gypsum powder, also known as putty powder, plays a very important role in our decoration process. Its main component is hydrated calcium sulfate, most of which are white transparent crystals. Due to the presence or absence of crystalline water, they are called "soft gypsum" and "hard gypsum", mainly used for wall masonry, pointing, and wall leveling. There is also a type of colored gypsum powder that can also play a decorative role and has a relatively low cost, Gypsum powder can be used as the main raw material for concrete expansion agent, crack resistance agent, self-leveling mortar, and as a composite mineralizer in the production of special cement.

石膏粉的作用

The role of gypsum powder

石膏粉是五大凝膠材料之一，廣泛用于建筑建材工業(yè)模具和藝術(shù)模型化學(xué)工業(yè)及農(nóng)業(yè)食品加工和醫(yī)藥美容等眾多應(yīng)用領(lǐng)域，是一種重要的工業(yè)原材料，通常為白色無(wú)色，有時(shí)因含雜質(zhì)而成灰淺黃淺褐等色。

Gypsum powder, one of the five major gel materials, is widely used in building materials industry, mold and art model, chemical industry, agricultural food processing, medicine and beauty and many other application fields. It is an important industrial raw material, usually white and colorless, and sometimes gray, light yellow and light brown due to impurities.

墻體找平

Wall leveling

在裝修中石膏粉一般用來(lái)做基層處理的，比如填平縫隙陰陽(yáng)角調(diào)直毛坯房墻面第一遍膩?zhàn)诱移降取Ｊ嗟恼辰佣群茫灰桩a(chǎn)生脫落現(xiàn)象，在用來(lái)進(jìn)行墻面找平時(shí)，一般并不是直接使用石膏粉的，里面也會(huì)加入滑石粉，否則施工會(huì)不太方便了。

Gypsum powder is generally used for grassroots treatment in decoration, such as filling gaps, straightening internal and external corners, and leveling the first layer of putty on the walls of rough rooms. Gypsum has good adhesion and is not prone to detachment. When used for wall leveling, gypsum powder is generally not directly used, and talcum powder is also added inside, otherwise construction will be inconvenient.

制作石膏水泥

Making gypsum cement

摻加適量的激發(fā)劑可生產(chǎn)硬石膏水泥或膠凝材料，適用于軟土地基的加固，墻體粉刷，機(jī)械模型，坑道支護(hù)及生產(chǎn)纖維壓力板等。

Adding an appropriate amount of activator can produce anhydrite cement or cementitious materials, suitable for reinforcement of soft soil foundations, wall painting, mechanical models, tunnel support, and production of fiber pressure boards.

其他作用

Other functions

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(chǎn)中用作復(fù)合礦化劑等。

Gypsum powder can be used as the main raw material for concrete expansion agent, crack resistance agent, self-leveling mortar, and as a composite mineralizer in the production of special cement.

石膏粉是什么?石膏粉的功效和作用

What is gypsum powder? The efficacy and function of gypsum powder

粘接力強(qiáng)

Strong adhesion

粉刷石膏與各種墻體基材(粘土磚水泥砌塊加氣混凝土粉煤灰磚石膏砌塊現(xiàn)澆混凝土頂棚等)都能很好地粘結(jié)，抹灰時(shí)不用刷任何界面劑，直接抹灰，一次成活，抹灰墻面不會(huì)出現(xiàn)空鼓開裂現(xiàn)象。

Plastering gypsum can bond well with various wall substrates (such as clay bricks, cement blocks, aerated concrete, fly ash bricks, gypsum blocks, cast-in-place concrete ceilings, etc.). When plastering, there is no need to brush any interface agent, and the plastering can be done directly. Once completed, the plastered wall will not experience hollowing and cracking.

表面裝飾性

Surface decoration

粉刷石膏墻面細(xì)膩光滑而不起灰，強(qiáng)度高不收縮，外觀典雅，無(wú)氣味，不返堿，無(wú)裂紋。

The plastered gypsum wall surface is delicate and smooth without dust, with high strength and no shrinkage. The appearance is elegant, odorless, non alkaline, and crack free.

防火性能

Fire performance

當(dāng)粉刷石膏抹面厚度為20mm時(shí)，耐火極限可達(dá)到2小時(shí)以上。

When the thickness of the plaster is 20mm, the fire resistance limit can reach more than 2 hours.
