内墙腻子胶粉起泡的原因及处理方法

来源:https://www.jnfhjc.com 日期:2022-04-07 发布人:juyehe

内墙装修一般情况下都采用普通的内墙腻子胶粉,使用的粘接剂多为羧甲基纤维素CMC和羧基予湖化淀粉胶,这两种粘接剂都会和灰钙、水泥中的碱性物质起凝胶反应。当碱性较高的墙体遇到中性内墙腻子胶粉中的水分就会立即产生反应出现小气泡。这是因为腻子所使用的的填充料为重质碳酸钙或滑石粉,属中性无强度不耐水。而墙体为水泥或石灰砂浆界面,属碱性。所以遇到碱性较高的墙面易产生气泡。

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节空气湿度大,内墙腻子胶粉界面非常容易吸湿返潮,它就会与碱性墙面发生化学反应,出现鼓泡、开裂、发霉、起皮脱落现象。特别是南方地区空气湿度大,起皮脱落现象更为严重。钢化抛光腻子同样常常在批刮时会出现起泡现象,原因是所使用的胶粘剂无透气功能,比如使用的掺假纤维素HPMC。掺有CMC或含有羧基成分的其他化工产品。
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.
这样现象发生的原因:一是返碱墙面。尤其是室内水泥现浇顶板为多见,原因是在顶板浇注过程中水泥砂浆中碱性物质随水沉淀聚积于顶板与模板之间,水份干燥蒸发后,室内水泥顶板表面就会呈现较高的碱性气泡。二是水泥砂浆墙面较粗糙,批刮腻子时将气体封闭在其中释放出的气体形成小气泡。如果出现起泡现象该如何处理呢?内墙腻子胶粉厂家为大家总结了一些处理办法:
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、河南内外墙腻子粉厂家建议更换有透气功能耐碱性胶粉,比如使用国标纤维素HPMC非标纯粉,或有透气功能的速溶树脂胶粉。
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、批腻子胶粉前可用水喷洒在粗糙墙面或罩白灰墙面上,让气体提前释放后在批腻子,即可避免出现起泡现象。
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.
