石膏粉又叫腻子粉，在我们装修过程中起着非常重要的作用，它的主要成分是含水的硫酸钙，大部分都呈白色的透明晶体，因有无结晶水分为“软石膏”和“硬石膏”，主要用来砌墙体，勾缝，墙面找平等，还有一种彩色石膏粉还可以起到装饰作用，成本比较低，石膏粉可以作为混凝土膨胀剂抗裂剂自流平砂浆的主要原材料，特种水泥生产中用作复合矿化剂等。

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

石膏粉是五大凝胶材料之一，广泛用于建筑建材工业模具和艺术模型化学工业及农业食品加工和医药美容等众多应用领域，是一种重要的工业原材料，通常为白色无色，有时因含杂质而成灰浅黄浅褐等色。

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.

墙体找平

Wall leveling

在装修中石膏粉一般用来做基层处理的，比如填平缝隙阴阳角调直毛坯房墙面第一遍腻子找平等。石膏的粘接度好，不易产生脱落现象，在用来进行墙面找平时，一般并不是直接使用石膏粉的，里面也会加入滑石粉，否则施工会不太方便了。

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

掺加适量的激发剂可生产硬石膏水泥或胶凝材料，适用于软土地基的加固，墙体粉刷，机械模型，坑道支护及生产纤维压力板等。

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

石膏粉可以作为混凝土膨胀剂抗裂剂自流平砂浆的主要原材料，特种水泥生产中用作复合矿化剂等。

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

粘接力强

Strong adhesion

粉刷石膏与各种墙体基材(粘土砖水泥砌块加气混凝土粉煤灰砖石膏砌块现浇混凝土顶棚等)都能很好地粘结，抹灰时不用刷任何界面剂，直接抹灰，一次成活，抹灰墙面不会出现空鼓开裂现象。

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.

表面装饰性

Surface decoration

粉刷石膏墙面细腻光滑而不起灰，强度高不收缩，外观典雅，无气味，不返碱，无裂纹。

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

当粉刷石膏抹面厚度为20mm时，耐火极限可达到2小时以上。

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