    膩子粉脫粉的現象是施工完成及干透后,用手觸摸有掉粉現象。
    The phenomenon of powder removal from putty powder is the phenomenon of powder touch by hand after construction and drying.
    產生原因:
    Cause:
    1、產品超過保質期,粘結力度大幅度下降;
    1. When the product exceeds the shelf life, the strength of the adhesive decreases significantly.
    2、內墻膩子粉拋光時間掌握不好,表面已經干燥后再進行拋光處理就會脫粉;
    2, internal wall putty powder polishing time is not good, the surface has been dry and then polishing treatment will be powder.
    3、外墻膩子粉,飾面時涂層比較薄,在夏天高溫下,水分揮發很快,面層未能足夠的水分進行固化,因而容易脫粉。
    3, the outer wall putty powder, the coating is thinner, in the summer high temperature, the moisture volatilization is very fast, the surface layer is not enough moisture to solidify, so it is easy to depowder.
    4、產品儲存不當,吸潮后粘結力大幅度下降。
    4, improper storage of products, the moisture absorption after a significant drop in cohesion.
    5、基層吸水率高,導致膩子干燥速度很快,沒有充足的水分進行固化。
    5. High water absorption at the grassroots level leads to fast drying of putty and no sufficient moisture for curing.
    解決方法:
    Resolvent:
    1、產品一定要在保質期內使用,如果超過保質期,必須進行試刮,經檢驗合格后,再行施工;
    1. The product must be used within the shelf life. If it exceeds the shelf life, it must be tested and scraped. After passing the inspection, it can be constructed again.
    2、內墻膩子面層拋光時要掌握適宜的拋光時間,拋光的較好時期就是待膩子表面水印消失后,立即進行拋光。實踐證明,飾面1~2m2就應該進行壓平或拋光處理。
    2. The proper polishing time should be mastered when the inner wall putty surface is polished. The better period of polishing is to polish the putty surface immediately after the watermark disappears. Practice has proved that the finishing 1~2m2 should be flattened or polished.
    3、外墻膩子表面干燥后,要進行適度打磨,并進行充分的淋水保養,一般保養分為兩次或兩次以上進行,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。
    3. After the surface of the outer wall of the putty is dry, it is necessary to make a moderate grinding and carry out adequate water spray maintenance. The general maintenance is divided into two or more times. If necessary, the transparent and closed primer is used as the second drenching solution with water (1:5). The effect will be better.
    4、產品一定要注意防水處理,應存在在陰涼干燥處,并且保證包封完好。
    4, the product must pay attention to waterproof treatment, should exist in a cool and dry place, and ensure good seal.
    5、夏天或高溫強風氣候條件下,在施刮膩子前盡量先用清水潤濕墻面,墻面表面無明水后即可施刮膩子。
    5. In summer or high temperature and strong wind conditions, try to wet the wall with clean water before applying the putty, and then apply the putty when there is no clear water on the wall surface.
