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.

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(qiáng)度不夠，導(dǎo)致脫粉。廠家盲目降低成本，膠粉的粘結(jié)強(qiáng)度差，添加量少，尤其是對(duì)于膩?zhàn)觾?nèi)墻而言，粘結(jié)強(qiáng)度與膠粉和膠水的質(zhì)量和添加量密切相關(guān)。

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?zhàn)訒r(shí)，膩?zhàn)拥牟牧线x擇和結(jié)構(gòu)非常重要，但它對(duì)諸如雙飛粉、滑爽石粉，硅粉石粉等填料沒(méi)有影響。但是，羧甲基纖維素鈉不能用作防水膩?zhàn)雍屯鈮δ佔(zhàn)?，因?yàn)轸燃谆w維素鈉與石灰鈣粉和白水泥漿反應(yīng)，會(huì)導(dǎo)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(huì)因化學(xué)反應(yīng)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(guó)內(nèi)有些廠家生產(chǎn)膩?zhàn)臃鄣脑O(shè)備簡(jiǎn)單，不是專(zhuān)用的攪拌設(shè)備，混合不均勻?qū)е履佔(zhàn)用摲邸?/p>

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.
