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(jié)空氣濕度大，內(nèi)墻膩?zhàn)幽z粉界面非常容易吸濕返潮，它就會(huì)與堿性墻面發(fā)生化學(xué)反應(yīng)，出現(xiàn)鼓泡、開(kāi)裂、發(fā)霉、起皮脫落現(xiàn)象。特別是南方地區(qū)空氣濕度大，起皮脫落現(xiàn)象更為嚴(yán)重。鋼化拋光膩?zhàn)油瑯映３Ｔ谂螘r(shí)會(huì)出現(xiàn)起泡現(xiàn)象，原因是所使用的膠粘劑無(wú)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(chǎn)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(xiàn)象發(fā)生的原因：一是返堿墻面。尤其是室內(nèi)水泥現(xiàn)澆頂板為多見(jiàn)，原因是在頂板澆注過(guò)程中水泥砂漿中堿性物質(zhì)隨水沉淀聚積于頂板與模板之間，水份干燥蒸發(fā)后，室內(nèi)水泥頂板表面就會(huì)呈現(xiàn)較高的堿性氣泡。二是水泥砂漿墻面較粗糙，批刮膩?zhàn)訒r(shí)將氣體封閉在其中釋放出的氣體形成小氣泡。如果出現(xiàn)起泡現(xiàn)象該如何處理呢?內(nèi)墻膩?zhàn)幽z粉廠家為大家總結(jié)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(nèi)外墻膩?zhàn)臃蹚S家建議更換有透氣功能耐堿性膠粉，比如使用國(guó)標(biāo)纖維素HPMC非標(biāo)純粉，或有透氣功能的速溶樹(shù)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?zhàn)幽z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?zhàn)樱纯杀苊獬霈F(xiàn)起泡現(xiàn)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.
