石膏粉的凝固时间的因素有哪些?

来源: 日期:2020-11-10 发布人:juyehe

石膏粉作为建筑材料的原料,如模型、线条等,许多建筑材料公司都自己制作。但早期生产也应注意相关事项,下面就来看看如何把握石膏粉的凝固时间。

  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项:
  Notes for the use of Paris gypsum:
  1. 石膏粉与水混合后,若水粉比例不合适,取适量调和。
  1. After mixing gypsum powder with water, if the proportion of water powder is not appropriate, take appropriate amount of mixing.
  2. 搅拌速度不宜过快,以免人为地带入气泡,形成过多的结晶,导致石膏膨胀,强度降低。
  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.灌注模型由一侧逐渐向另一侧移动,通过摇动灌注,消除气泡,填充所有细小部位。

  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.
  石膏在凝固过程中体积膨胀,影响熟石膏凝固速率的因素有熟石膏质量、熟石膏掺水比例不当、搅拌时间和速度、水温等。你可以用建筑胶水。另外,还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,水越多石膏凝固的时间越长,石膏密度越低;反之,水越多,凝固时间越短,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据具体应用要求进行控制。搅拌时间越长,石膏凝结时间越快。一般来说,搅拌至石膏粉非常均匀,然后就可以浇铸了。搅拌时间一般控制在5分钟以内。石膏粉浇注容器与凝固时间的关系。浇注容器吸水与否影响凝固时间,而浇注容器不吸水。
  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.
