The color is simply the color difference, the electrostatic spray equipment, after high temperature curing, surface color shades, called "color".

通常情况下静电喷涂设备喷涂中的涂层色差问题发生在调试阶段：

Normally, the color difference of coating in electrostatic spraying equipment occurs in the debugging stage:

1、涂层厚薄不均匀引起的色差。

1, color difference caused by uneven coating thickness.

解决方法：调整好喷粉工艺参数和保证静电喷涂设备运行良好以确保涂层厚度均匀一致。

Solution: adjust the injection process parameters and ensure the good performance of the electrostatic spraying equipment to ensure the uniform thickness of the coating.

2、粉末颜料分布不均匀引起的色差。

2, color difference caused by uneven distribution of powder pigment.

解决的方法：提高粉末质量，保证粉末的色差数据相差不大而且正负统一。

Solution: improve the quality of powder, ensure the powder color difference is not big, and the unity of positive and negative.

3、固化温度不同引起的色差。

3, the color difference caused by curing temperature.

解决方法：控制好设定温度和输送链速度，以保持工件固化温度和时间的一致性和稳定性。

The solution is to control the setting temperature and speed of the conveyor chain to keep the consistency and stability of the temperature and time of the workpiece.

4、粉末的批次不同引起色差

4, batches of powder caused by different color difference

解决方法：在喷涂或者喷塑不同批次，甚至同一批次都会造成色差，如果用的漆料和塑粉一样的话，在同一个喷涂线喷涂，参数基本一致，就可能杜绝这种问题的发生。

Solution: spray or spray in different batches, even the same batch can cause color, if the paint and plastic powder with the same words in the same line spraying spraying parameters are basically the same, put an end to this problem may occur.

5、烘箱温度不均匀引起色差

5, oven temperature is uneven, cause color difference

解决方法：由于存在温差所以颜色肯定不一样，要保证工件在180～200度受温烘烤20～30分钟。

Solution: due to the existence of temperature difference, so the color is certainly not the same, to ensure that the workpiece in 180~200 degrees by warm baking for 20~30 minutes.

设备出现问题主要的原因就是对后期的保养和维护没有重视起来，才造成了出现诸多的问题，只要我们能够对喷塑流水线定期的维护和保养，那么就能避免很多这样的问题，也能增加设备的使用寿命。遮盖性不好的粉末涂料，好比有一定透明度的白纸，必须达到一定厚度才会表现出良好的遮盖性；遮盖性合格的粉末，如同上面讲的铁板，很薄的厚度就会呈现良好的遮盖性。

The main reason is the problem of equipment maintenance and maintenance of the late did not pay attention to it, it has created many problems, as long as we can to spray line regular maintenance and maintenance, so you can avoid many of these problems, can also increase the service life of the equipment. Cover the powder coating is not good, like a transparent white, must reach a certain thickness will show good covering; covering qualified powder, as mentioned above the iron plate, thin thickness will show good covering power.
