腻子是一种用于墙面修补的基材，为接下来的装修（绘画、壁纸）打下良好的基础。腻子分为内墙和外墙，外墙腻子抗风、耐晒，附着性高，强度高，环保指标略低。

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.

腻子粉

Putty powder

有部分人反馈，现在腻子粉脱粉导致乳胶漆脱落、鼓包开裂是一个较为严重的问题。目前腻子最常见的工后问题是腻子粉掉粉、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.粘合强度不够，导致脱粉。厂家盲目降低成本，胶粉的粘结强度差，添加量少，尤其是对于腻子内墙而言，粘结强度与胶粉和胶水的质量和添加量密切相关。

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.在使用腻子时，腻子的材料选择和结构非常重要，但它对诸如双飞粉、滑爽石粉，硅粉石粉等填料没有影响。但是，羧甲基纤维素钠不能用作防水腻子和外墙腻子，因为羧甲基纤维素钠与石灰钙粉和白水泥浆反应，会导致脱粉。此外，在石灰钙粉和白水泥浆中加入聚丙烯酰胺作为防水涂料也会因化学反应而脱粉。

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.混合搅拌不均匀是脱粉的主要原因，国内有些厂家生产腻子粉的设备简单，不是专用的搅拌设备，混合不均匀导致腻子脱粉。

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.
