Putty powder is a kind of building decoration materials, the main components are talcum powder and glue. Just bought a layer of white on the surface of the blank room is putty, usually the whiteness of putty is more than 90, fineness is more than 330.

Putty can be divided into interior wall and exterior wall. Exterior wall putty is resistant to wind and sun, so it has high gel, high strength and low environmental protection index. The composite index of interior wall putty is good, healthy and environmental protection, so the interior wall is not for external use, and the exterior wall is not for internal use.

Usually putty is gypsum or cement-based, so the surface is rough and easy to bond firmly. But in the construction, we should brush a layer of interface agent on the base to seal the base, and improve the adhesion of the wall, so that the putty can be better bonded on the base.

Many users of putty powder have to admit that it is a very serious problem for putty powder to come off. It will cause the peeling off of emulsion paint, the bulging and cracking of putty layer, and then the cracking of emulsion paint finish.

Putty powder off powder, off white is the common putty construction problems, to understand the reasons for putty powder off powder, first to understand the basic raw material components of putty powder and curing principle, and then combined with the putty construction of the wall dry degree, water absorption, temperature, weather dry degree.
今天福華建材小編找出了膩?zhàn)臃鄣舴鄣闹饕?，一起來看看吧?/div>
Today, Fuhua building materials Xiaobian found out the main reason of putty powder off powder, let's have a look!
原因一
Reason one
膩?zhàn)拥恼辰Y(jié)強(qiáng)度不夠造成脫粉，生產(chǎn)廠家一味的降低成本，膠粉的粘結(jié)強(qiáng)度差，添加量較小，特別是內(nèi)墻膩?zhàn)樱辰Y(jié)強(qiáng)度的大小，脫粉不脫粉和膠粉以及膠水的質(zhì)量和添加量有很大關(guān)系。
The adhesive strength of putty is not enough, which leads to powder removal. The manufacturer blindly reduces the cost. The adhesive strength of rubber powder is poor, and the amount of addition is small. Especially for the interior wall putty, the adhesive strength, powder removal without powder removal are closely related to the quality and amount of rubber powder and glue.
原因二
The second reason
設(shè)計(jì)配方不合理，選材的問題和結(jié)構(gòu)的問題，在膩?zhàn)优浞街泻苤匾?。比如羥丙基甲基纖維素（HPMC）做內(nèi)墻不防水的膩?zhàn)?，HPMC雖然很貴，但對(duì)雙飛粉，滑石粉，硅灰石粉等填充料不起作用，如果僅使用HPMC就會(huì)引起脫粉，而價(jià)格低的CMC、CMS反到不脫粉，但是CMC、CMS不能做防水膩?zhàn)樱膊荒茏鐾鈮δ佔(zhàn)樱驗(yàn)镃MC和CMS遇到灰鈣粉、白水泥起反應(yīng)，這都會(huì)引起脫粉，也有把聚丙烯酰胺加入灰鈣粉、白水泥做為防水涂料，也會(huì)起化學(xué)反應(yīng)引起脫粉。
Unreasonable design formula, material selection and structure are very important in putty formula. For example, hydroxypropyl methylcellulose (HPMC) is used as non waterproof putty for interior wall. Although HPMC is very expensive, it does not work for filling materials such as Shuangfei powder, talcum powder and wollastonite powder. If only HPMC is used, it will cause powder removal. However, CMC and CMS with low price can not be used as waterproof putty or exterior wall putty, because CMC and CMS meet with lime powder, talcum powder and silica fume powder White cement reacts, which will cause depigmentation. In addition, adding polyacrylamide into lime calcium powder and white cement as waterproof coating will also cause chemical reaction to cause depigmentation.
原因三
The third reason
混合攪拌不均勻，是造成內(nèi)外墻膩?zhàn)用摲鄣闹饕颍珖?guó)有的生產(chǎn)廠家生產(chǎn)膩?zhàn)臃墼O(shè)備簡(jiǎn)單，五花八門，不是專用攪拌設(shè)備，攪拌不均勻，引起膩?zhàn)用摲邸?/div>
Uneven mixing and mixing is the main reason for the internal and external wall putty powder removal. Some manufacturers in China produce putty powder with simple and varied equipment, which is not a special mixing equipment. Uneven mixing causes putty powder removal.
