內墻翻新再刮膩子之后發黃怎么回事呢？

來源：http://m.man5g.cn 日期：2021-07-10 發布人：

內墻翻新再刮膩子之后發黃怎么回事呢？這與墻體老舊以及使用了重鈣膩子粉有關：

What's the matter with yellowing after interior wall renovation and putty? This is related to the old wall and the use of heavy calcium putty powder

舊墻膩子使用了大量的PVA膠水，膠水老化分解，產生不飽和酸，不飽和酸與膩子中鈣離子反應，生成相應黃色的鈣鹽。

A lot of PVA glue is used in old wall putty. The glue is aged and decomposed to produce unsaturated acid, which reacts with calcium ion in putty to produce corresponding yellow calcium salt.

濟南膩子粉分享其解決方法：

Jinan putty powder shares its solution:

1、用環保膠水滾涂兩遍，徹底干透后，再行施刮睡寶牌環保水性內墻膩子；

1. Roll twice with environmental glue, dry thoroughly, and then apply Shuibao brand environmental water-based interior wall putty;

2、用睡寶白色封閉底漆滾涂兩道，徹底干透后，再批刮膩子。

2. Roll two coats of sleeping treasure white sealing primer, dry thoroughly, and then apply putty.

3、全部采用膏狀膩子施工，或用板材膩子施工。

3. All of them are constructed with paste putty or plate putty.

果用乳膠漆刷墻，除去變黃部分，重新批刮膩子，按照正常的刷墻步驟做：

If the wall is painted with latex paint, the yellowing part is removed, and the putty is applied again

1、先刮膩子，膩子主要作用是墻面襯底，找平的作用，（做兩到三遍，每遍都要等完全干透后再做下遍）。

1. The main function of putty is the wall substrate, leveling (do two to three times, each time must wait until completely dry before the next time).

2、砂紙打磨平整。

2. Sand paper to smooth.

3、依次刷底漆和面漆（或滾刷），底漆二遍，面漆三遍，每遍要等完全干透后再做下遍。

3. Brush primer and top coat (or roller brush) in turn, two times of primer and three times of top coat, and each time shall be done after it is completely dry.
