腻子起泡现象:施工过程中产生气泡,过一段时间后腻子表面就会起泡。
Putty bubble phenomenon: during the construction of the bubble, after a period of time, the putty surface will blister.
产生原因:
Causes:
1、基底过于粗糙,批荡速度过快;
1, the base is too rough, and the speed of batting is too fast.
2、一次施工腻子层过厚,大于2.0mm;
2. Once the putty layer is too thick, it is greater than 2.0mm.
3、基层含水率过高,同时密度太大或太小。由于含有丰富的空隙,且腻子含水率高,因而不透气,空气被封闭在空隙空腔内,不容易消除。
3, the moisture content at the grassroots level is too high, and the density is too large or too small. Because of rich voids and high moisture content of putty, it is impermeable and air is sealed in the void cavity, which is not easy to eliminate.
4、施工一段时间后,才在表面出现的爆裂起泡,主要是搅拌不均匀造成的,浆体中含有来不及溶解的粉状颗粒,施工后,大量吸收水分,溶胀形成爆裂。
4. After construction for a period of time, the surface of the explosive bubble, mainly caused by uneven mixing, slurry contains powdery particles can not be dissolved, after construction, a large number of water absorption, swelling to form burst.
解决方法:
Resolvent:
1、出现大面积起泡的腻子面,用铲刀直接压破小泡口,重新用合适的腻子施刮起泡的面层。
1. Appear the putty surface of large area bubbles, press the small bubbles directly with spade knife, scrape the bubbled surface with suitable putty again.
2、腻子一般在搅拌均匀后,静置10分钟左右后,然后用电动搅拌机再次搅拌后上墙。
2. Putty is stirred evenly in general, standing for about 10 minutes, and then stirred again with an electric mixer on the wall.
3、施工第二道或者最后一道面层出现起泡现象,应在水印消除前用刮刀进行压泡破除处理,保证腻子面上不出现气泡。
3. When bubbles appear on the second or the last surface layer during the construction, a scraper should be used to break the bubbles before the watermark is eliminated to ensure that bubbles do not appear on the putty surface.
4、特别粗糙的墙面,一般底料尽可能选择粗的腻子。
4, especially rough wall, the general base material as far as possible to choose coarse putty.
5、在墙体过分干燥或风大光照强烈的环境下,先尽可能用清水润湿墙面,待墙体无明水之后,进行腻子层的施刮。
5. Under the condition of excessively dry wall or strong wind and light, wet the wall with clean water as far as possible, and wipe putty layer after the wall has no clear water.
