Putty powder is one of the materials for house decoration. Its raw materials are often talc powder with glue, which can be bought in stores. It is generally divided into two kinds: outer wall and inner wall. The former resists wind and sunshine, but the environmental protection effect is low. The latter has good comprehensive ability and environmental protection performance. When we use putty powder, we will find that it will appear dedusting phenomenon. Why? Today, we will introduce the reasons for putty powder dedusting.

　　Putty powder dedusting phenomenon: after finishing decoration construction and drying out, there is powder dropping phenomenon with hand touch

　　1、內(nèi)墻膩?zhàn)臃蹝伖鈺r(shí)間掌握不好，表面已經(jīng)干燥后再進(jìn)行拋光處理就會脫粉;

　　1. The polishing time of putty powder for inner wall is not well controlled, and the surface will be dedusted after drying and polishing.

　　2、外墻膩?zhàn)臃郏椕鏁r(shí)涂層比較薄，在夏天高溫下，水分揮發(fā)很快，面層未能足夠的水分進(jìn)行固化，因而容易脫粉。

　　2. Exterior wall putty powder, the coating is thinner when facing, in summer high temperature, moisture volatilization quickly, the surface layer can not be enough moisture to solidify, so it is easy to de-powder.

　　3、產(chǎn)品超過保質(zhì)期，粘結(jié)力度大幅度下降。

　　3. When the product exceeds its shelf life, the bonding strength decreases dramatically.

　　4、產(chǎn)品儲存不當(dāng)，吸潮后粘結(jié)力大幅度下降。

　　4. The bonding force decreases dramatically after moisture absorption due to improper storage of products.

　　5、基層吸水率高，導(dǎo)致膩?zhàn)痈稍锼俣群芸?，沒有充足的水分進(jìn)行固化。

　　5. The high water absorption of the base causes the putty to dry quickly and does not have enough water to solidify.

　　1、內(nèi)墻膩?zhàn)用鎸訏伖鈺r(shí)要掌握適宜的拋光時(shí)間，拋光的佳時(shí)期就是待膩?zhàn)颖砻嫠∠Ш?，立即進(jìn)行拋光。實(shí)踐證明，飾面1~2m2就應(yīng)該進(jìn)行壓平或拋光處理。

　　1. The proper polishing time should be mastered when polishing the inner wall putty surface. The best polishing time is to polish the putty surface immediately after the watermarking disappears. Practice has proved that 1~2m2 finish should be flattened or polished.

　　2、外墻膩?zhàn)颖砻娓稍锖?，要進(jìn)行適度打磨，并進(jìn)行充分的淋水保養(yǎng)，一般保養(yǎng)分為兩次或兩次以上進(jìn)行，如果有必要，請用透明封閉底漆兌水(1：5)作為第二道淋水液，效果會更好。

　　2. After the exterior wall putty surface is dried, it should be properly polished and fully watered. Generally, the maintenance can be divided into two or more times. If necessary, please use transparent sealed primer watering (1:5) as the second watering solution, the effect will be better.

　　3、產(chǎn)品一定要在保質(zhì)期內(nèi)使用，如果超過保質(zhì)期，必須進(jìn)行試刮，經(jīng)檢驗(yàn)合格后，再行施工;

　　3. Products must be used within the shelf life. If they exceed the shelf life, they must be scraped and constructed after passing the inspection.

　　4、產(chǎn)品一定要注意防水處理，應(yīng)存在在陰涼干燥處，并且保證包封完好。

　　4. Waterproof treatment should be paid attention to. The product should be stored in a cool and dry place, and the encapsulation should be kept intact.

　　5、夏天或高溫強(qiáng)風(fēng)氣候條件下，在施刮膩?zhàn)忧昂孟扔们逅疂櫇駢γ?，墻面表面無明水后即可施刮膩?zhàn)印?/div>
