Building gypsum powder is commonly used in building decoration. It is often used to paint walls, leveling in the air or making wall panels and gypsum blocks. When considering the construction period, how long can the building gypsum powder be dry is also an important time node, many processes are stopped after the building gypsum powder is dry.

　　普通来说，建筑石膏粉只需求几分钟就开端初步凝固了，而完整变硬则需求1天左右的时间。假如是在墙面空中等挂完石膏，三到四天也足够完整枯燥了，当然这也和建筑石膏粉自身的质量息息相关，建筑石膏粉的标号标号高的普通就凝结的快。

　　Generally speaking, it takes only a few minutes for building gypsum powder to begin to solidify initially, while it takes about a day for complete hardening. If hang gypsum in the wall air, three to four days is enough complete and boring, of course, this is also closely related to the quality of building gypsum powder itself, building gypsum powder label high ordinary condensation fast.

　　当然建筑石膏粉多久能干还取决于天气要素，湿度和温度会影响建筑石膏粉的枯燥速度。湿度越大，枯燥越慢。温度高的话，建筑石膏粉会相对枯燥的快一些，在一些状况下会运用不同温度的水来调和建筑石膏粉也是这个原理。

　　Of course, how long building gypsum powder can dry depends on weather factors, humidity and temperature will affect the drying speed of building gypsum powder. The higher the humidity, the slower the boredom. If the temperature is high, the building gypsum powder will be relatively dull and faster. In some cases, different temperatures of water will be used to mix the building gypsum powder is also the principle.

　　另一个影响建筑石膏粉枯燥速度的要素是添加剂，柠檬酸、白乳胶、腻子粉是常见的添加剂，这些添加剂会影响建筑石膏粉枯燥的速度，便当成型或者加快枯燥。

　　Another factor affecting drying speed of building gypsum powder is additives. Citric acid, white latex and putty powder are common additives. These additives can affect drying speed of building gypsum powder, so they can be used as moulding or accelerate drying.

　　地板专用石膏粉十分常见，但是如何选择优质的地板专用石膏粉对很多人来说是一个小问题。选择地板专用石膏粉能够从以下三个规范判别。

　　Floor gypsum powder is very common, but how to choose high quality floor gypsum powder is a small problem for many people. Choosing gypsum powder for flooring can be distinguished from the following three criteria.

　　首先是细度，字面的了解是地板专用石膏粉颗粒的大小，石膏粉细度越细，石膏颗粒外表积大，与水接触面大，更能充沛的反响，成型后强度也更高。

　　First of all, fineness, literal understanding is the size of gypsum powder particles for floor use. The finer the gypsum powder, the larger the surface area of gypsum particles, the greater the contact surface with water, the more abundant the response, and the higher the strength after shaping.

　　优质地板专用石膏粉的另一个判别规范是凝结时间，这也是在施工中十分重要的一个规范。石膏粉的凝结时间又分为初凝时间和终凝时间。初凝时间是石膏粉变稠的时间，终凝时间是石膏粉终成型的时间。质量合格石膏粉凝结时间应该是：在规范稠度下，普通初凝时间不小于7min，终凝时间不大于30min。

　　Another criterion for distinguishing gypsum powder for high quality flooring is setting time, which is also a very important criterion in construction. The setting time of gypsum powder can be divided into initial setting time and final setting time. The initial setting time is the thickening time of gypsum powder, and the final setting time is the final forming time of gypsum powder. The setting time of qualified gypsum powder should be: under the standard consistency, the ordinary initial setting time should not be less than 7 minutes, and the final setting time should not be more than 30 minutes.

　　强度是石膏成型后的质量判别规范，成型的石膏粉强度指标分为抗折强度和抗压强度。其中比拟重要的是抗压强度，石膏粉的2h湿抗压强度普通为6Mpa以上，干抗压强度12Mpa以上。

　　Strength is the quality criterion of gypsum after forming. The strength index of gypsum powder can be divided into flexural strength and compressive strength. Compressive strength is the most important one. The wet compressive strength of gypsum powder in 2H is generally more than 6Mpa, and the dry compressive strength is more than 12Mpa.

　　建筑石膏粉多久能干是建筑施工需求思索的重要问题，也有很多的综合思索要素，经过以上的引见，置信大家都有了一定的理解，假如您想进一步理解这个问题，欢送联络我们。
