如何把握石膏粉的凝固時間！

來源：http://www.wavc.cn 日期：2020-10-22 發布人：

石膏粉作為建筑材料的原料，如模型、線條等，許多建筑材料公司都自己制作。但早期生產也應注意相關事項，下面就來看看如何把握石膏粉的凝固時間。

　　Gypsum powder as raw materials for building materials, such as models, lines, etc., many building materials companies have their own production. But early production should also pay attention to the relevant matters, the following is to see how to grasp the setting time of gypsum powder.

　　巴黎石膏使用注意事項:

　　Notes for the use of Paris gypsum:

　　1. 石膏粉與水混合后，若水粉比例不合適，取適量調和。

　　1. After mixing gypsum powder with water, if the proportion of water powder is not appropriate, take appropriate amount of mixing.

　　2. 攪拌速度不宜過快，以免人為地帶入氣泡，形成過多的結晶，導致石膏膨脹，強度降低。

　　2. Mixing speed should not be too fast, so as not to artificially bring in bubbles, forming too many crystallization centers, resulting in gypsum expansion and strength reduction.

　　3.灌注模型由一側逐漸向另一側移動，通過搖動灌注，消除氣泡，填充所有細小部位。

　　3. The perfusion model moves gradually from one side to the other. By shaking the perfusion, the bubbles are eliminated and all the small parts are filled.

　　石膏在凝固過程中體積膨脹，影響熟石膏凝固速率的因素有熟石膏質量、熟石膏摻水比例不當、攪拌時間和速度、水溫等。你可以用建筑膠水。另外，還可以使用免粘石膏粉，直接用水混合即可，水、石膏粉的混合比，水越多石膏凝固的時間越長，石膏密度越低;反之，水越多，凝固時間越短，密度越大，牢度越高。

　　The volume expansion of gypsum in the solidification process, the factors affecting the solidification rate of plaster are the quality of plaster, the improper proportion of water in plaster, mixing time and speed, water temperature, etc. You can use building glue. In addition, non-stick gypsum powder can also be used, which can be directly mixed with water. The more water, the longer the gypsum solidification time, the lower the density of gypsum; conversely, the more water, the shorter the solidification time, the higher the density and the higher the fastness.

　　水和石膏粉的配比需要根據具體應用要求進行控制。攪拌時間越長，石膏凝結時間越快。一般來說，攪拌至石膏粉非常均勻，然后就可以澆鑄了。攪拌時間一般控制在5分鐘以內。石膏粉澆注容器與凝固時間的關系。澆注容器吸水與否影響凝固時間，而澆注容器不吸水。

　　The proportion of water and gypsum powder should be controlled according to the specific application requirements. The longer the stirring time is, the faster the setting time of gypsum is. Generally speaking, it is stirred until the gypsum powder is very uniform, and then it can be cast. Stirring time is generally controlled within 5 minutes. The relationship between the pouring container of gypsum powder and solidification time. Whether the pouring vessel absorbs water or not affects the solidification time, while the pouring vessel does not absorb water.
