Gypsum powder has a wide range of applications. It can not only be used in cement industry, but also produce chemical raw materials and building materials. However, many people find that the coagulation speed of hard plaster is also slow

1、掺水量的多少；根据研究标明，石膏粉掺入的水量越多，凝聚速度就越慢；反之，凝聚速度就越快。若想减缓石膏粉的凝聚速度，可以从掺水量来入手。

1. The amount of water mixed; According to the research, the more water is added into gypsum powder, the slower the coagulation speed is; On the contrary, the faster the coagulation speed is. If you want to slow down the coagulation speed of gypsum powder, you can start with the amount of water.

2、水温的高低；水温的高低也影响着石膏粉的凝聚速度。水温越高，其凝聚速度就快。

2. Water temperature; The water temperature also affects the coagulation rate of gypsum powder. The higher the water temperature, the faster the coagulation rate.

石膏粉的凝聚速度受哪些因素影响？

What factors affect the coagulation rate of gypsum powder?

3、拌合时间；凝聚速度还与拌和的时间长短有关，拌和时间越长，凝聚速度就越快。因此，可以缩短拌和时间，来控制石膏粉的凝聚速度。

3. Mixing time; The coagulation speed is also related to the mixing time. The longer the mixing time, the faster the coagulation speed. Therefore, the mixing time can be shortened to control the coagulation speed of gypsum powder.

4、周围环境；施工环境湿度比较大，那么凝聚的速度就会越慢。反之，周围环境干燥、通风，其凝聚速度就会变快。

4. Surrounding environment; The higher the humidity of the construction environment, the slower the condensation speed will be. On the contrary, if the surrounding environment is dry and ventilated, its coagulation speed will become faster.

在装修行业中，石膏粉一般作为校正阴阳角、填缝等基础处理。虽然有粘接能力强，不容易脱落等优势，但施工墙面也会出现开裂现象，除去石膏粉自身质量之外，就让小编带大家来了解一下出现这种开裂情况怎么去解决。

In the decoration industry, gypsum powder is generally used as the basic treatment for correcting internal and external corners and caulking. Although it has the advantages of strong bonding ability and not easy to fall off, the construction wall will also crack. In addition to the quality of gypsum powder, let's let Xiaobian take you to understand how to solve this kind of crack.

1、石膏粉防开裂的处理方法；先对已经开裂的部分进行处理：用工具开八字缝到底，然后用石膏刷胶填实，干燥之后再贴牛皮纸。其次，施工过程中，可以控制单遍抹灰的厚度，分次找平，对于抹灰厚度过大的情况，特殊加固解决，以此防止出现开裂等情况。

1. Anti cracking treatment method of gypsum powder; First treat the cracked part: use tools to open the splayed seam to the end, then use gypsum to brush glue and fill it, and then paste kraft paper after drying. Secondly, during the construction process, the thickness of single plastering can be controlled and leveled by times. In case of excessive plastering thickness, special reinforcement can be solved to prevent cracking and other situations.

2、石膏粉接缝处理的方法；墙面结构与顶棚如果是不同材质的话，交接处粘贴接缝应用专门的胶带，且要求顺缝粘贴，粘贴牢固平整。?

2. Gypsum powder joint treatment method; If the wall structure and ceiling are made of different materials, the joint shall be pasted with special adhesive tape, and it is required to paste along the joint, which shall be firm and flat.?

3、石膏粉阴阳角弹线找方的方法；用红外线水平仪在墙面上弹出垂直线和水平线，上返到顶棚的较低位置弹顶棚水平线，用粉刷石膏将角落不足的地方刮平，然后确定墙面大面积平整度控制线。

3. The method of snapping the line and finding the square of the internal and external corners of gypsum powder; Use the infrared level to pop up the vertical line and horizontal line on the wall, return to the lower position of the ceiling, snap the horizontal line of the ceiling, scrape the insufficient corner with plaster, and then determine the flatness control line of the wall in a large area.
