膩子粉是平整墻體表面的一種裝飾材料，也是一種厚漿狀涂料，是涂料粉刷前必不可少的一種材料。那么濟南膩子粉開裂原因預防以及怎么打磨呢？下面為您講解。

Putty powder is a kind of decorative material for leveling the wall surface, as well as a thick paste coating. It is an indispensable material before painting. So how to prevent the cracking of Jinan putty powder and how to polish it? Let's explain it to you.

膩子粉開裂是指膩子層產生裂縫，產生的原因：

The crack of putty powder refers to the crack of putty layer, which is caused by:

1、基層松動、漲縮開裂，接縫處未有效處理開裂。

1. The base course is loose, swollen and cracked, and the cracks at the joints are not effectively treated.

2、單遍批刮太厚，干燥太快，表干里不干。

2. Single pass batch scraping is too thick, drying is too fast, and the surface is not dry inside.

3、膩子粉里外層不配套，外硬里松。

3. The inner and outer layers of putty powder are not matched, and the outer layer is hard and the inner layer is loose.

4、膩子中混有除水外的其它材料。

4. The putty is mixed with other materials except water.

預防膩子粉開裂的措施：

Measures to prevent cracking of putty powder:

1、基層結構要穩定;避免使用伸縮系數大的基材;接逢處理要按規范施工。

1. The basic structure should be stable; Avoid using substrates with large expansion coefficient; The joint treatment shall be carried out according to the specification.

2、需厚批膩子處應薄批多遍。

2. Where thick putty is required, thin putty shall be applied for several times.

3、膩子里外層應配套使用，忌里松外硬或里外層膩子硬度差異太大。

3. The inner and outer layers of putty shall be used together. It is forbidden to loose the inner and outer layers or the hardness difference between the inner and outer layers of putty is too large.

4、膩子調配時忌混入除水外的其它材料。

4. It is forbidden to mix putty with other materials except water.

整改措施：

Rectification measures:

1、結構松動要待結構穩定后施工。

1. When the structure is loose, it shall be constructed after the structure is stable.

2、水泥砂漿開裂或交接縫開裂應重新做接縫處理，可用百年達接縫先進行接縫處理，在批刮膩子。

2. The cement mortar crack or joint crack shall be treated again, and the joint can be treated with Bainianda joint king first, and then putty shall be applied.

膩子粉怎么打磨

How to polish putty powder

1、膩子粉刮糙整個過程中，無可避免出現一些微小的缺點，比如膩子交界處的鋼筋搭接、一部分批刮起來薄或過厚留出的劃痕、墻面吸潮造成的針孔等，這類缺點也是可以依據墻面拋光處理來解決的。

1. In the whole process of roughening putty powder, there are inevitably some minor defects, such as the overlapping of steel bars at the junction of putty, the scratches left by some thin or too thick scrapes, and the pinholes caused by moisture absorption on the wall. These defects can also be solved according to the wall polishing treatment.

2、膩子粉的重要作用雖然是地坪找平，但只是刮糙膩子的話，僅僅是做了一半的地坪找平工作上，除此之外的一半，也是管理決策預期效果的一半，要依據拋光處理來解決。這也是做墻面拋光處理的作用。

2. Although the important role of putty powder is to level the floor, if it is only to scrape rough putty, it is only half of the floor leveling work done. In addition, the other half is also half of the expected effect of management decisions, which should be solved according to polishing treatment. This is also the role of wall polishing.

此外整體拋光處理后的膩子粉表面結構更加均勻一致，可以提高墻漆的具體表現預期效果，而且避免了因表面結構的區別很有可能造成的一些難點（如面漆一部分色偏等）。更多相關事項就來我們網站http://www.man5g.cn進行咨詢！

In addition, the surface structure of putty powder after overall polishing treatment is more uniform, which can improve the specific performance of wall paint and avoid some difficulties that may be caused by the difference of surface structure (such as color deviation of part of finish paint).
