何謂膩子粉？所謂膩子粉又稱為填泥，屬于一種厚漿狀涂料。涂施于底漆上或直接涂施于物體上，用以清除被涂物表面上高低不平的缺陷。下面來講講濟南膩子粉脫粉現象以及產生原因。

What is putty powder? The so-called putty powder, also known as putty, belongs to a thick paste coating. Apply to the primer or directly to the object to remove uneven defects on the surface of the coating. Next, let's talk about the phenomenon of Jinan putty powder peeling off and its causes.

膩子粉脫粉

Putty powder peeling

現象：施工完成及干透后，用手觸摸有掉粉現象。

Phenomenon: After the construction is completed and dried thoroughly, there is a phenomenon of powder falling when touched by hand.

產生原因：

Cause of occurrence:

1、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；

1. The polishing time of the putty powder on the inner wall is not well controlled. If the surface is dry and then polished, the powder will peel off;

2、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。

2. The exterior wall putty powder has a relatively thin coating when facing, and under high temperatures in summer, the moisture evaporates quickly. The surface layer does not have enough moisture to solidify, making it easy for the powder to peel off.

3、產品超過保質期，粘結力度大幅度下降。

3. The product has exceeded its shelf life and the bonding strength has significantly decreased.

4、產品儲存不當，吸潮后粘結力大幅度下降。

4. Improper storage of the product results in a significant decrease in adhesion after moisture absorption.

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. The high water absorption of the base layer results in a fast drying rate of the putty and insufficient moisture for curing.

解決方法：

Solution:

1、內墻膩子面層拋光時要掌握適宜的拋光時間，拋光的佳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。

1. When polishing the inner wall putty surface layer, it is necessary to grasp the appropriate polishing time. The best polishing period is to immediately polish after the watermark on the putty surface disappears. Practice has shown that the surface area of 1-2 square meters should be flattened or polished.

2、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。

2. After the surface of the exterior wall putty is dry, it should be moderately polished and thoroughly watered for maintenance. Generally, maintenance is divided into two or more times. If necessary, use a transparent sealing primer mixed with water (1:5) as the second watering solution, which will have a better effect.

3、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；

3. The product must be used within the shelf life. If the shelf life is exceeded, a trial scraping must be carried out, and construction can only be carried out after passing the inspection;

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 be stored in a cool and dry place, and ensure that the packaging is intact.

5、夏天或高溫強風氣候條件下，在施刮膩子前好先用清水潤濕墻面，墻面表面無明水后即可施刮膩子。

5. In summer or high temperature and strong wind weather conditions, before applying putty, it is recommended to wet the wall surface with clean water. After there is no open water on the wall surface, putty can be applied.
