Gypsum thread is a decorative material mainly made of gypsum. The material name of gypsum is soft gypsum, which can be made into gypsum after heating and precision processing. And because gypsum itself is a cohesive material, its weight can also be considered lightweight; The characteristic of gypsum line is not only its white color, but also its significant advantage is that its gypsum surface is very lubricated, fine, and not coarse. Due to its own physical characteristics - micro expansion, it will not form cracks during use; Due to the fact that the interior of gypsum raw materials is filled with open spaces of all sizes, its insulation and insulation functions are becoming increasingly important.

石膏粉的用途：

The purpose of gypsum powder:

1、鋪平墻面。石膏粉能夠填平墻面的縫隙和陰陽角的調整，以及毛坯房墻面的膩子找平，使用石膏粉找平的墻面是不會輕易產生脫落現象的。

1. Pave the wall surface. Gypsum powder can fill the gaps and adjust the internal and external corners of the wall, as well as level the putty on the rough room wall surface. The wall surface leveled with gypsum powder will not easily fall off.

2、制作石膏。水泥可以將石膏粉與適量的激發劑混合制作石膏水泥或者是膠凝材料，這類材料會應用于我們基地的加固以及墻體的粉刷工作。

2. Make gypsum. Cement can be mixed with gypsum powder and an appropriate amount of activator to produce gypsum cement or cementitious materials, which will be applied to the reinforcement of our base and wall painting work.

3、作基層處理。石膏粉的用途就是用于我們的基層處理，處理基層的時候，一般我們是不直接使用石膏粉的，應當在里面加入一些滑石粉，這樣施工會方便許多。

3. Conduct grassroots treatment. The purpose of gypsum powder is to treat our base layer. When treating the base layer, we usually do not directly use gypsum powder. Instead, we should add some talcum powder inside, which will be much more convenient for construction.

4、較強的粘接力。石膏粉有很強的粘接能力，在何種基層上施工，都能很好的連接，因而抹石灰的時候都不需要添加任何粘結劑，直接施工，一次成形，后期也不會出現空鼓和開裂的現象。

4. Strong adhesion. Gypsum powder has strong bonding ability and can be well connected on any base layer. Therefore, when applying lime, no adhesive needs to be added. It can be directly applied and formed in one go, and there will be no hollowing or cracking in the later stage.
