5060全讯彩金白菜人士分析石膏粉的混合顺序是什么?

来源: 日期:2020-10-12 发布人:juyehe

先加水后加入石膏粉,记住这一点很重要,先加水后搅拌石膏粉是很困难的,石膏的硬度和搅拌均匀的程度是成正比的,搅拌越均匀,牢度越高。
  It is important to remember that it is very difficult to mix gypsum powder after adding water. The hardness of gypsum is proportional to the degree of uniformity. The more uniform the stirring, the higher the fastness.
  凝结时间主要与所加水量有关(需另加),其次是搅拌时间、浇注容器、温湿度。首先是水、石膏粉的混合比例,水越多石膏凝结时间越长,石膏密度越低,牢度越低,水越少凝结时间越短,密度越大,牢度越高,具体需要根据使用要求加以控制。
  The setting time is mainly related to the amount of water added (additional), followed by mixing time, pouring container, temperature and humidity. The first is the mixing ratio of water and gypsum powder. The more water, the longer the setting time of gypsum, the lower the density of gypsum, the lower the fastness, the shorter the setting time of less water, the greater the density and the higher the fastness, which need to be controlled according to the specific requirements.
  然后大家将讨论搅拌时间。一般情况下,搅拌至石膏粉均匀即可浇注。一般可在5分钟内控制。铸造容器与凝固时间的关系:铸入非吸水性容器(硅胶模具等)凝固时间不变,铸入吸水性容器(纸箱、木箱等)凝固时间缩短。
  Then we will discuss the mixing time. Generally, mixing until the gypsum powder is even can be poured. Usually it can be controlled in 5 minutes. The relationship between casting vessel and solidification time: the solidification time of casting non-water absorbent vessel (silica gel mould, etc.) remains unchanged, while the solidification time of casting water absorbent vessel (carton, wooden box, etc.) is shortened.
  它主要是化学沉积的产物,常形成巨大的矿层或透镜体,见于石灰岩、红页岩和砂岩、泥灰岩和粘土岩系列中,常与硬石膏和石盐共存。硬石膏层位于地表附近,由于外部压力的降低,在地表水的作用下,硬石膏层转化为石膏。同时体积增大约30%,对石膏层造成破坏。

  It is mainly the product of chemical deposition and often forms huge ore beds or lenses. It is found in limestone, red shale and sandstone, marl and claystone series, and often coexists with anhydrite and gypsum salts. Anhydrite layers are located near the surface. Due to the decrease of external pressure, under the action of surface water, anhydrite layers are converted into gypsum. At the same time, the volume of the gypsum layer was increased by about 30%, which caused damage to the gypsum layer.
  鉴定特征:硬度低,一套极性完全解理,并可对各种形貌特征进行鉴定。致密块状石膏与碳酸盐的区别在于它的硬度低,在酸存在下不起泡。
  Identification characteristics: low hardness, a complete set of polarity cleavage, and can identify various morphological characteristics. The difference between compact massive gypsum and carbonate is that it has low hardness and does not foam in the presence of acid.
  这很容易理解,石膏粉中的水粉被模具吸取,当然凝固时间短。温度、湿度与凝固的关系:温度越高,凝固时间越短;温度越低,凝固时间越长;湿度越大,凝固时间越长;湿度越低,凝固时间越短。
  It is easy to understand that the water powder in the gypsum powder is absorbed by the mould, of course, the solidification time is short. The relationship between temperature, humidity and solidification: the higher the temperature, the shorter the solidification time; the lower the temperature, the longer the solidification time; the higher the humidity, the longer the solidification time; the lower the humidity, the shorter the solidification time.
