膩子粉強度不夠出現(xiàn)脫粉的原因

來源：http://www.wavc.cn 日期：2022-11-22 發(fā)布人：

膩子粉是在漆類裝修施工前，屬于表面找平粉狀的一類材料，能夠進行施工面進行預處理的措施。在這過程當中如果膩子粉的粘結(jié)力不夠的話，容易成脫粉的問題，造成濟南膩子粉脫粉的因素有很多，比如原料的原因、施工的原因、配方設(shè)計不合理等。

Putty powder is a kind of surface leveling powder before paint decoration construction, which can be used for pretreatment of construction surface. In this process, if the adhesive force of putty powder is not enough, it is easy to cause the problem of powdering. There are many factors that cause the powdering of putty powder in Jinan, such as the reason for raw materials, the reason for construction, and the unreasonable formula design.

1、灰鈣粉、白水泥當中的無機粘結(jié)劑不純，摻有大量的雙飛粉。市面上出售的打著多功能灰鈣粉、多功能白水泥的招牌，但是都不純，因為大量使用這些不純的無機粘結(jié)劑，內(nèi)外墻防水膩子肯定脫粉更不防水。

1. The inorganic binder in lime calcium powder and white cement is impure and mixed with a large amount of Shuangfei powder. The signboards on the market with multi-function calcium lime powder and multi-function white cement are impure. Because of the large use of these impure inorganic binders, the waterproof putty on the interior and exterior walls must be de powdered and not waterproof.

2、膩子的粘結(jié)強度不夠造成脫粉，生產(chǎn)廠家一味的降低成本，膠粉的粘結(jié)強度差，添加量較小，非常是內(nèi)墻膩子，粘結(jié)強度的大小，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。

2. The adhesive strength of putty is not enough to cause powder removal. The manufacturer blindly reduces the cost. The adhesive strength of glue powder is poor, and the addition amount is small. Especially for interior wall putty, the size of the adhesive strength, and the non powder removal are closely related to the quality and addition amount of glue powder and glue.

3、灰鈣的質(zhì)量有很大關(guān)系，灰鈣的含量低和灰鈣中的CaO和Ca(OH)2比例不合適，和纖維素沒有太大關(guān)系，要說有關(guān)系的話無非算羥丙基甲基纖維素的保水性差。

3. The quality of lime calcium has a lot to do with it. The low content of lime calcium has nothing to do with the proportion of CaO and Ca (OH) 2 in the lime calcium, and it has nothing to do with cellulose. If it has something to do with it, it is simply the poor water retention of hydroxypropyl methyl cellulose.

4、填充料的質(zhì)量的不同也容易造成脫粉，內(nèi)外墻膩子大量的使用填充料，但各地重鈣粉、滑石粉里面CO2、CO3的含量不同，酸堿度不同也會造成膩子的脫粉，比如西安和內(nèi)蒙的內(nèi)墻膩子粉用同樣的膠粉，但滑石粉、重鈣粉不同，在西安不脫粉，在內(nèi)蒙就脫粉，在河南、東北不脫粉，而在一些地區(qū)就脫粉。

4. The difference in the quality of filler is also easy to cause depowmering. A large number of filler materials are used for internal and external wall putty. However, the content of CO2 and CO3 in heavy calcium powder and talcum powder is different in different places, and different pH values will also cause depowmering of putty. For example, the same glue powder is used for internal wall putty powder in Xi'an and Inner Mongolia, but talcum powder and heavy calcium powder are different. No depowmering is allowed in Xi'an, no depowmering is allowed in Inner Mongolia, and no depowmering is allowed in Henan and Northeast, In some areas, the powder is removed.

5、在膩子調(diào)配的配方中一旦設(shè)計配方不合理，諸如選材以及結(jié)構(gòu)引起的問題。比如羥丙基甲基纖維素（HPMC）做內(nèi)墻不防水的膩子，HPMC雖然很貴，但對雙飛粉，滑石粉，硅灰石粉等填充料不起作用，如果僅使用HPMC就會引起脫粉，而價格低的CMC、CMS反到不脫粉，但是CMC、CMS不能做防水膩子，也不能做外墻膩子，因為CMC和CMS遇到灰鈣粉、白水泥起反應(yīng)，這都會引起脫粉，也有把聚丙烯酰胺加入灰鈣粉、白水泥做為防水涂料，也會起化學反應(yīng)引起脫粉。

5. In the formulation of putty preparation, once the design formulation is unreasonable, such as problems caused by material selection and structure. For example, hydroxypropyl methyl cellulose (HPMC) can be used as waterproof putty for interior walls. Although HPMC is expensive, it does not work on fillers such as Shuangfei powder, talcum powder, wollastonite powder, etc. If HPMC is used only, it will cause depowmerization, while CMC and CMS with low prices will not do so. However, CMC and CMS cannot be used as waterproof putty or exterior wall putty, because CMC and CMS react with lime calcium powder and white cement, which will cause depowmerization, Polyacrylamide is also added to lime calcium powder and white cement as waterproof coating, which will also cause chemical reaction to cause powder removal.

如果想要提高膩子的硬度的話，也不是沒有辦法，可以通過添加一種增進膠粉，進而提高膩子粉的硬度，如此一來不但能夠提高膩子粉的硬度，也能增加它的亮光度。在拋光兩三天后，用手指都很難劃上痕跡，保濕性很不錯能夠有效的防止干裂。其中的用量只需在每噸膩子粉中加三到五千克就可以了，能有效的降低了施工難度，降低墻面找平的難度。這種方法適合各種墻面的裝潢。

If you want to improve the hardness of putty, there is no way. You can increase the hardness of putty powder by adding a kind of glue powder, which can not only improve the hardness of putty powder, but also increase its brightness. After polishing for two or three days, it is difficult to mark with your fingers, and the moisturizing property is very good, which can effectively prevent dry cracks. The amount of putty powder only needs to add three to five thousand grams per ton, which can effectively reduce the difficulty of construction and wall leveling. This method is suitable for decoration of various walls.
