膩子是一種用于墻面修補的基材，為接下來的裝修（繪畫、壁紙）打下良好的基礎。膩子分為內墻和外墻，外墻膩子抗風、耐曬，附著性高，強度高，環保指標略低。

Putty is a substrate used for wall repair, laying a good foundation for subsequent decoration (painting, wallpaper). Putty is divided into interior and exterior walls. Exterior wall putty is wind resistant, sun resistant, has high adhesion, high strength, and slightly lower environmental indicators.

有部分人反饋，現在膩子粉脫粉導致乳膠漆脫落、鼓包開裂是一個較為嚴重的問題。目前膩子非常常見的工后問題是膩子粉掉粉、掉白。

Some people have given feedback that the detachment of putty powder causing latex paint to peel off, bulge and crack is a serious problem. The most common post work problem with putty at present is the loss of putty powder and whitening.

1.粘合強度不夠，導致脫粉。廠家盲目降低成本，膠粉的粘結強度差，添加量少，尤其是對于膩子內墻而言，粘結強度與膠粉和膠水的質量和添加量密切相關。

1. Insufficient adhesive strength leads to powdering. Manufacturers blindly reduce costs, resulting in poor bonding strength and low dosage of adhesive powder, especially for putty interior walls. The bonding strength is closely related to the quality and dosage of adhesive powder and glue.

2.在使用膩子時，膩子的材料選擇和結構非常重要，但它對諸如雙飛粉、滑爽石粉，硅粉石粉等填料沒有影響。但是，羧甲基纖維素鈉不能用作防水膩子和外墻膩子，因為羧甲基纖維素鈉與石灰鈣粉和白水泥漿反應，會導致脫粉。此外，在石灰鈣粉和白水泥漿中加入聚丙烯酰胺作為防水涂料也會因化學反應而脫粉。

When using putty, the material selection and structure of putty are very important, but it has no effect on fillers such as double fly powder, smooth stone powder, silica powder, etc. However, sodium carboxymethyl cellulose cannot be used as waterproof putty and exterior wall putty because it reacts with lime calcium powder and white cement slurry, causing powdering. In addition, adding polyacrylamide as a waterproof coating to lime calcium powder and white cement slurry can also cause powdering due to chemical reactions.

3.混合攪拌不均勻是脫粉的主要原因，國內有些廠家生產膩子粉的設備簡單，不是專用的攪拌設備，混合不均勻導致膩子脫粉。

3. Uneven mixing is the main reason for powder removal. Some domestic manufacturers have simple equipment for producing putty powder, which is not a dedicated mixing equipment. Uneven mixing leads to powder removal of putty.
