1、何種條件發(fā)生變化？
1, what conditions have changed?
2、變化到何種程度？
2, to what extent?
3、為什么會產(chǎn)生這樣的變化？
3, why is there such a change?
為弄清楚這些問題，一般按照以下步驟進(jìn)行：
To clarify these problems, the following steps are normally carried out:
1、分別檢查涂料編號、批號和稀釋劑是否正確，涂料粘度是否在工藝范圍內(nèi)，并逐一校對，監(jiān)測。
1. Check whether the paint number, batch number and diluent are correct, whether the viscosity of the paint is within the scope of the process, and check one by one, monitoring.
2、檢查原材料鋁卷在進(jìn)行過程中是否存在污染。
2, check whether there is pollution in the process of raw aluminum coil.
3、檢查涂裝輥研磨是否存在缺陷。
3, check whether there are defects in the painting roller.
4、檢查涂裝輥、上料輥、提漆輥、計(jì)量輥轉(zhuǎn)速匹配和生產(chǎn)線速是否在工藝范圍內(nèi)。
4. Check the speed matching of coating roll, feeding roll, stripping roll, measuring roll and production line speed in the process range.

5、檢查設(shè)備，氣壓是否正常。
5, check the equipment, air pressure is normal.
6、檢查操作人員操作是否正確。
6, check whether the operator is correct.
7、檢查環(huán)境濕度，溫度是否改變。
7, check the environment humidity, whether the temperature changes.
8、檢查供漆泵是否漏氣、漏油。
8. Check whether the paint pump is leaking or leaking.
9、檢查濾網(wǎng)是否完好。
9, check whether the screen is intact.
10、檢查上料輥$涂裝輥夾緊程度。
10. Check the feeding roller and the clamping degree of the coating roller.
11、檢查涂料盤隔離檔板是否正確。
11. Check whether the isolation tray is correct.
12、檢查刮刀是否緊貼刮干凈。
12, check whether the scraper is clinging to clean.
13、檢查張力是否正常。
13, check whether the tension is normal.
14、由于涂裝生產(chǎn)工藝流程較長，所以處理方法建議從發(fā)現(xiàn)缺陷處開始向上一個工序方向逐一按上述方法進(jìn)行檢查，直至找到造成缺陷問題所在，然后作對應(yīng)處理。
14. Because of the long process flow of painting production, the treatment method must be checked one by one from the point of defect detection to the direction of the next process until the defect is found, and then the corresponding treatment is carried out.
