在現代工業制造領域，噴塑技術憑借其高效性、環保性以及卓越的裝飾性能，已成為眾多產品表面處理的首選工藝。然而，在涂裝噴涂過程中卻遭遇了噴粉線運行過程中噴塑工件不上粉或斑駁或堆粉等情況的困擾。除此幾點，以下這些因素同樣可能導致噴塑的困擾，值得我們深入探討。

　　In the field of modern industrial manufacturing, spray coating technology has become the preferred process for surface treatment of many products due to its high efficiency, environmental friendliness, and excellent decorative performance. However, during the painting and spraying process, there were problems such as the powder coating line running and the sprayed workpiece not being coated with powder, being mottled, or accumulating powder. In addition to these points, the following factors may also cause difficulties in spray painting and are worth exploring in depth.

　　一、噴涂過程中出現的問題

　　1、 Problems encountered during the spraying process

　　A)

　　A)

　　工件不上粉、或上粉很少、或吸附力差容易掉落

　　Workpieces that are not coated with powder, have very little powder coating, or have poor adsorption force are prone to falling off

　　可能原因：

　　Possible reasons:

　　1、噴槍故障，如高壓包損壞、電路板故障等等；

　　1. Spray gun malfunction, such as damage to the high-voltage package, circuit board malfunction, etc;

　　2、工件接地不好；

　　2. Poor grounding of the workpiece;

　　3、噴槍噴涂參數如電壓、電流、出粉大小等與工件類型不匹配；

　　3. Spray gun spraying parameters such as voltage, current, powder size, etc. do not match the type of workpiece;

　　4、噴槍距離工件太遠或太近；

　　4. The spray gun is too far or too close to the workpiece;

　　5、粉末問題，如太潮濕、金屬粉末、粉末比重太大等等；

　　5. Powder issues, such as excessive moisture, metal powder, high powder density, etc;

　　6、或噴房內局部風速過快導致此區域部件不好上粉末。

　　6. Or the local wind speed in the spray booth is too fast, which makes it difficult to apply powder to the components in this area.

　　建議解決方法：

　　Suggested solution:

　　1、仔細檢查噴槍、控制器等，發現并解決問題；

　　1. Carefully inspect the spray gun, controller, etc., identify and solve problems;

　　2、掛具接觸點被粉末固化后的絕緣體包裹導致接地不好，需清除；
