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、铺平墙面。石膏粉能够填平墙面的缝隙和阴阳角的调整，以及毛坯房墙面的腻子找平，使用石膏粉找平的墙面是不会轻易产生脱落现象的。

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。水泥可以将石膏粉与适量的激发剂混合制作石膏水泥或者是胶凝材料，这类材料会应用于我们基地的加固以及墙体的粉刷工作。

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、作基层处理。石膏粉的用途就是用于我们的基层处理，处理基层的时候，一般我们是不直接使用石膏粉的，应当在里面加入一些滑石粉，这样施工会方便许多。

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、较强的粘接力。石膏粉有很强的粘接能力，在何种基层上施工，都能很好的连接，因而抹石灰的时候都不需要添加任何粘结剂，直接施工，一次成形，后期也不会出现空鼓和开裂的现象。

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.
