延長石膏粉凝固時間的方法?

來源：http://www.wavc.cn 日期：2019-01-30 發(fā)布人：

　　關(guān)于延長石膏粉凝固時間的方法是什么?下面由小編介紹一下：

　　What is the method of prolonging the solidification time of gypsum powder?

　　石膏粉的凝固時間一般取決與石膏粉的標(biāo)號，標(biāo)號高的一般就凝結(jié)的快。石膏粉和水反應(yīng)的速度是很快的，一般的操作時間只有幾分鐘，第1分鐘的時間將石膏粉撒入水中，第2分鐘攪拌，第3分鐘倒模，很快就會硬化。

　　The setting time of gypsum powder generally depends on the label of gypsum powder, and the higher the label, the faster the setting. The reaction speed between gypsum powder and water is very fast. The general operation time is only a few minutes. The gypsum powder is sprinkled into water in the first minute, stirred in the second minute and reversed in the third minute. It will harden quickly.

　　建筑石膏粉：在裝修粉刷過程中，需要延長石膏粉的凝固時間。不過讓石膏凝固速度降慢的方法是在把石膏粉加水的時候使用溫度較低的涼水，水越?jīng)瞿趟俣染驮铰粗脽崴蜁芸臁Ｈ绻X得這個辦法不行，還可以加入檸檬酸或者先在石膏粉里摻好膩子粉，在水里摻上108膠白乳膠和纖維素，再調(diào)和。

　　Building gypsum powder: In the process of decoration and painting, it is necessary to prolong the setting time of gypsum powder. However, the way to slow down the solidification rate of gypsum is to use cooler water when adding water to gypsum powder. The cooler the water is, the slower the solidification rate will be. On the contrary, hot water will be used quickly. If this method is not feasible, citric acid can be added or putty powder mixed in gypsum powder, 108 latex and cellulose mixed in water, and then blended.

　　模具石膏粉：如果硬化速度過快，可以往水中加一些緩凝劑，如：乙醇(酒精)約占6-8%，可以延長操作時間。一般的模型，使用建筑石膏粉或高強(qiáng)度石膏粉。如果鑄模用，那需要專門的石膏鑄粉。另外需要注意石膏粉與水的比例，水的多少直接影響石膏模的質(zhì)量。

　　Mould gypsum powder: If the hardening speed is too fast, some retarders can be added to the water, such as: ethanol (alcohol) accounts for about 6-8%, which can prolong the operation time. General models use building gypsum powder or high strength gypsum powder. If it is used for casting, special gypsum powder is needed. In addition, attention should be paid to the proportion of gypsum powder to water, the amount of water directly affects the quality of gypsum mould.
