Many people see their house decorated with white putty powder is so smooth and bright, but some putty powder will appear blistering phenomenon, do you know why, for you to analyze the reasons, as long as the construction avoids the next will make a bright wall.
1.基材吸水量過低辐践。導(dǎo)致膩?zhàn)优螘r(shí)相對(duì)保水時(shí)間過長(zhǎng)而使膩?zhàn)釉趬ι祥L(zhǎng)期處于漿料態(tài)而不干,使氣泡不容易被泥刀擠壓出上煤!而產(chǎn)生針孔狀毛孔休玩,就是為什么工程上批刮模板頂比墻體氣泡更多的原因,墻體吸水量大劫狠,而模板頂吸水量極低哥捕。
1. The water absorption of the base material is too low. As a result, the relative water holding time of the putty scraping is too long, and the putty is in the slurry state on the wall for a long time, so that the bubbles are not easy to be squeezed out by the mud knife! The pinhole pore is the reason why there are more bubbles on the top of the scraping formwork than on the wall. The water absorption of the wall is large, while the water absorption of the top of the formwork is very low.
2.單遍批刮太厚,膩?zhàn)涌紫吨械目諝鉀]有壓擠出來嘉熊。
2. The air in the pore of putty is not extruded because the single batch scraping is too thick.
3.基層過于粗糙遥赚,有細(xì)小孔洞。批刮時(shí)膩?zhàn)訉⒖锥磧?nèi)空氣壓縮阐肤,之后空氣壓力反彈形成氣泡凫佛。
3. The base is too rough with small holes. The putty compresses the air in the hole during batch scraping, and then the air pressure rebounds to form bubbles.

4.耐水涂料、高標(biāo)號(hào)混凝土等密閉性好的基面不透起泡孕惜。
4. Waterproof coatings, high-grade concrete and other well-sealed base surfaces are impervious to foaming.
5.基層過于干燥愧薛,吸水率過高,易致面層膩?zhàn)託馀荻唷?/div>
5. The base is too dry, the water absorption rate is too high, and the surface putty is easy to cause more bubbles.
6.纖維素添加量過大衫画。
6. Excessive cellulose addition.
7.高溫施工時(shí)膩?zhàn)右桩a(chǎn)生氣泡毫炉。
7. Putty is easy to produce bubbles during high temperature construction.
