　　很多師傅在膩子粉施工或者施工后會發現膩子粉開裂、打磨粗糙，為什么會出現這些問題呢?有解決方案嗎?下面bainida給出了詳細的解釋。

　　Many masters will find cracks and rough polishing of putty powder after construction or construction. Why do these problems occur? Is there a solution? Bainida gives a detailed explanation below.

　　膩子粉開裂是指膩子層開裂，產生原因:

　　The cracking of putty powder refers to the cracking of putty layer, and the causes are as follows:

　　1. 基礎疏松，膨脹收縮開裂，接縫處無有效的開裂處理。

　　1. The foundation is loose, expansion and contraction cracks, and there is no effective crack treatment at the joint.

　　2、單批刮擦過厚，干燥過快，在表中干燥。

　　2. The single batch is scratched too thick, dried too fast, and dried in the table.

　　3.膩子粉外層不匹配，外層硬，內層松。

　　3. The outer layer of putty powder does not match, the outer layer is hard and the inner layer is loose.

　　4. 膩子與除水以外的其他材料混合。

　　4. Putty is mixed with other materials except water.

　　防止膩子粉開裂的措施:

　　Measures to prevent cracking of putty powder:

　　1. 穩定的基礎結構;避免使用膨脹系數大的基材;根據施工規范進行處理。

　　1. Stable foundation structure; avoid using base material with large expansion coefficient; handle according to construction specifications.

　　2、需要厚批膩子的應是薄批膩子。

　　2. If thick putty is needed, thin putty shall be applied.

　　3.膩子的內層和外層應配套使用。

　　3. The inner and outer layers of putty shall be used together.

　　4. 混合膩子時，應避免混合除水以外的其他材料。

　　4. When mixing putty, avoid mixing other materials except water.

　　糾正措施:

　　Corrective actions:

　　1. 施工應在結構松動穩定后進行。

　　1. The construction shall be carried out after the structure is loose and stable.

　　2、水泥砂漿開裂或接縫開裂應重新做接縫處理，可達100年接縫線先進接縫處理，在批刮膩子。

　　2. If the cement mortar cracks or the joint cracks, the joint treatment shall be carried out again, which can reach 100 years of advanced joint treatment of the joint line, and the putty shall be applied.

　　膩子粉磨粗是指膩子粉批刮活，磨砂痕粗，造成這種現象的原因:

　　Coarseness of putty grinding means that the putty powder is scraped alive and the grinding mark is thick, which causes this phenomenon:

　　1. 磨料太厚。

　　1. The abrasive is too thick.

　　2. 膩子粉與其他物質混合。

　　2. Putty powder is mixed with other substances.

　　3.油灰不干燥。

　　3. The putty is not dry.

　　4. 防水膩子粉干得太快，保持濕潤時間短，粘結強度達不到正常。

　　4. The waterproof putty powder dried too fast, kept wet for a short time, and the bonding strength was not up to normal.

　　防止膩子粉粗磨的措施:

　　Measures to prevent rough grinding of putty powder:

　　1、選擇360#- 600#砂紙打磨。

　　1. Select 360 × 600 × sandpaper for grinding.

　　2. 混合膩子粉時只加水。

　　2. Only add water when mixing putty powder.

　　3、膩子打磨時，應干燥至80%以上。

　　3. When the putty is polished, it shall be dried to more than 80%.

　　4. 施工中應根據環境氣候，適當控制膩子的干燥時間。

　　4. The drying time of putty shall be properly controlled according to the environmental climate during construction.

　　整改措施:底漆后用細砂紙打磨或用滑石粉劃傷。

　　Rectification measures: Polish with fine sandpaper or scratch with talcum powder after primer.
