優良石膏粉的標準是什么？

來源：http://www.wavc.cn 日期：2019-03-14 發布人：

建筑石膏粉是建筑裝修常用的資料，經常被用來粉刷墻面，空中找平或者用來制造墻面板和石膏塊。在思索工期的時分，建筑石膏粉多久能干也是一個重要的時間節點，很多工序都在建筑石膏粉枯燥后停止。

　　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.

　　普通來說，建筑石膏粉只需求幾分鐘就開端初步凝固了，而完整變硬則需求1天左右的時間。假如是在墻面空中等掛完石膏，三到四天也足夠完整枯燥了，當然這也和建筑石膏粉自身的質量息息相關，建筑石膏粉的標號標號高的普通就凝結的快。

　　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.

　　當然建筑石膏粉多久能干還取決于天氣要素，濕度和溫度會影響建筑石膏粉的枯燥速度。濕度越大，枯燥越慢。溫度高的話，建筑石膏粉會相對枯燥的快一些，在一些狀況下會運用不同溫度的水來調和建筑石膏粉也是這個原理。

　　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.

　　另一個影響建筑石膏粉枯燥速度的要素是添加劑，檸檬酸、白乳膠、膩子粉是常見的添加劑，這些添加劑會影響建筑石膏粉枯燥的速度，便當成型或者加快枯燥。

　　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.

　　地板專用石膏粉十分常見，但是如何選擇優良的地板專用石膏粉對很多人來說是一個小問題。選擇地板專用石膏粉能夠從以下三個規范判別。

　　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.

　　首先是細度，字面的了解是地板專用石膏粉顆粒的大小，石膏粉細度越細，石膏顆粒外表積大，與水接觸面大，更能充沛的反響，成型后強度也更高。

　　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.

　　優良地板專用石膏粉的另一個判別規范是凝結時間，這也是在施工中十分重要的一個規范。石膏粉的凝結時間又分為初凝時間和終凝時間。初凝時間是石膏粉變稠的時間，終凝時間是石膏粉終成型的時間。質量合格石膏粉凝結時間應該是：在規范稠度下，普通初凝時間不小于7min，終凝時間不大于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.

　　強度是石膏成型后的質量判別規范，成型的石膏粉強度指標分為抗折強度和抗壓強度。其中比擬重要的是抗壓強度，石膏粉的2h濕抗壓強度普通為6Mpa以上，干抗壓強度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問題，也有很多的綜合思索要素，經過以上的引見，置信大家都有了一定的理解，假如您想進一步理解這個問題，歡送聯絡我們。

　　How long can building gypsum powder be competent is an important issue in the construction needs thinking, there are many comprehensive thinking elements, after the introduction above, I believe that everyone has a certain understanding, if you want to further understand this issue, send us a farewell contact.
