Ordinary interior wall putty powder is commonly used for interior wall decoration. Most of the adhesives used are carboxymethyl cellulose CMC and carboxyl group as Lake starch glue. These two adhesives react with alkaline substances in gray calcium and cement. When the wall with high alkalinity meets the water in the putty powder of neutral interior wall, it will react immediately and produce small bubbles. This is because the filler used for the putty is heavy calcium carbonate or talc powder, which is neutral, non strength and water-resistant. The wall is cement or lime mortar interface, which is alkaline. Therefore, it is easy to produce bubbles on the wall with high alkalinity.

在每年七八月份梅雨季節空氣濕度大，內墻膩子膠粉界面非常容易吸濕返潮，它就會與堿性墻面發生化學反應，出現鼓泡、開裂、發霉、起皮脫落現象。特別是南方地區空氣濕度大，起皮脫落現象更為嚴重。鋼化拋光膩子同樣常常在批刮時會出現起泡現象，原因是所使用的膠粘劑無透氣功能，比如使用的摻假纖維素HPMC。摻有CMC或含有羧基成分的其他化工產品。

In the plum rain season in July and August every year, the air humidity is high, and the putty rubber powder interface of the inner wall is very easy to absorb moisture and return to moisture. It will have a chemical reaction with the alkaline wall, resulting in bubbling, cracking, mildew, peeling and falling off. Especially in the south, the air humidity is high, and the peeling and falling off phenomenon is more serious. Toughened polishing putty also often bubbles when scraping, because the adhesive used has no air permeability function, such as adulterated cellulose HPMC. Other chemical products mixed with CMC or containing carboxyl groups.

這樣現象發生的原因：一是返堿墻面。尤其是室內水泥現澆頂板為多見，原因是在頂板澆注過程中水泥砂漿中堿性物質隨水沉淀聚積于頂板與模板之間，水份干燥蒸發后，室內水泥頂板表面就會呈現較高的堿性氣泡。二是水泥砂漿墻面較粗糙，批刮膩子時將氣體封閉在其中釋放出的氣體形成小氣泡。如果出現起泡現象該如何處理呢?內墻膩子膠粉廠家為大家總結了一些處理辦法：

The reasons for this phenomenon: first, return to alkali wall. In particular, the indoor cement cast-in-situ roof is common, because the alkaline substances in the cement mortar precipitate and accumulate between the roof and the formwork with water during the roof pouring process. After the water is dried and evaporated, the surface of the indoor cement roof will show high alkaline bubbles. Second, the cement mortar wall is rough. When applying putty, the gas will be sealed in it, and the released gas will form small bubbles. How to deal with bubbles? The manufacturer of interior wall putty and rubber powder summarized some treatment methods for you:

1、河南內外墻膩子粉廠家建議更換有透氣功能耐堿性膠粉，比如使用國標纖維素HPMC非標純粉，或有透氣功能的速溶樹脂膠粉。

1. Henan interior and exterior wall putty powder manufacturers recommend replacing alkali resistant rubber powder with air permeability function, such as using national standard cellulose HPMC non-standard pure powder or instant resin rubber powder with air permeability function.

2、批膩子膠粉前可用水噴灑在粗糙墻面或罩白灰墻面上，讓氣體提前釋放后在批膩子，即可避免出現起泡現象。

2. Before applying putty rubber powder, water can be sprayed on the rough wall or covered with lime. After the gas is released in advance, apply putty to avoid foaming.
