轻质抹灰石膏粉为什么会脱粉?

来源: 日期:2022-01-25 发布人:juyehe

轻质抹灰石膏已经逐渐代替了传统的抹灰材料,得到了建筑行业的广泛认可。但是也有业主反映,在使用这种新型的抹灰石膏装饰新房的时候,会出现墙面掉粉的现象。这是因为什么原因导致的呢?有什么应对方法吗?下面,我们就来一起了解一下。

Lightweight plastering gypsum has gradually replaced the traditional plastering materials and has been widely recognized by the construction industry. However, some owners reported that when using this new type of plastering gypsum to decorate the new house, there will be a phenomenon of wall powder falling off. What is the reason for this? Is there any way to deal with it? Now, let's have a look.
1、抹灰石膏配合比错误产生脱粉。在其施工中,如果抹灰石膏的配合比中石膏用量较低,那么就会导致石膏裹藏不住骨料,骨料偏细,比表面积随之大,裹藏骨料的胶凝材料用量也相对增加,从而导致墙面脱粉。
1. The mix proportion of plastering gypsum is wrong, resulting in powder removal. In its construction, if the amount of gypsum in the mix proportion of plastering gypsum is low, it will lead to that the gypsum can not wrap the aggregate, the aggregate is too thin, the specific surface area will be large, and the amount of cementitious material wrapping the aggregate will also be relatively increased, resulting in wall de powdering.

2、错误的施工方法导致脱粉。在施工过程中,施工人员为了贪图省事,节约材料,会将已经凝固的砂浆直接兑水使用,如此也会导致墙面脱粉。
2. The wrong construction method leads to de pulverization. In the process of construction, in order to save trouble and materials, the constructors will directly mix the solidified mortar with water, which will also lead to wall de dusting.
3、轻质抹灰石膏的凝结时间也会影响脱粉问题的产生。如果凝结时间过长,即便浆体保水性正常,但表面也会因为局部水分蒸发影响抹灰石膏的水化,干透后就会有粉化现象。
3. The setting time of light plastering gypsum will also affect the occurrence of powder removal. If the setting time is too long, even if the water retention of the slurry is normal, the hydration of plastering gypsum will be affected by local water evaporation, and there will be pulverization after drying.
