    膩子起泡現象:施工過程中產生氣泡,過一段時間后膩子表面就會起泡。
    Putty bubble phenomenon: during the construction of the bubble, after a period of time, the putty surface will blister.
    產生原因:
    Causes:
    1、基底過于粗糙,批蕩速度過快;
    1, the base is too rough, and the speed of batting is too fast.
    2、一次施工膩子層過厚,大于2.0mm;
    2. Once the putty layer is too thick, it is greater than 2.0mm.
    3、基層含水率過高,同時密度太大或太小。由于含有豐富的空隙,且膩子含水率高,因而不透氣,空氣被封閉在空隙空腔內,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、施工一段時間后,才在表面出現的爆裂起泡,主要是攪拌不均勻造成的,漿體中含有來不及溶解的粉狀顆粒,施工后,大量吸收水分,溶脹形成爆裂。
    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.
    解決方法:
    Resolvent:
    1、出現大面積起泡的膩子面,用鏟刀直接壓破小泡口,重新用合適的膩子施刮起泡的面層。
    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、膩子一般在攪拌均勻后,靜置10分鐘左右后,然后用電動攪拌機再次攪拌后上墻。
    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層出現起泡現象,應在水印消除前用刮刀進行壓泡破除處理,保證膩子面上不出現氣泡。
    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、特別粗糙的墻面,一般底料盡可能選擇粗的膩子。
    4, especially rough wall, the general base material as far as possible to choose coarse putty.
    5、在墻體過分干燥或風大光照強烈的環境下,先盡可能用清水潤濕墻面,待墻體無明水之后,進行膩子層的施刮。
    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.
