Adjust suitable electrostatic voltage

一般情况在50KV-60KV即可,大粉量远距离喷涂的电压可为60KV-80KV之间(不宜过度)复喷和静电屏蔽比较严重时应使用低电压,一般在30KV-50KV之间。

Generally, it can be done at 50KV-60KV. The voltage of long-distance spraying with large amount of powder can be between 60KV-80KV (not excessive) and low voltage should be used when the electrostatic shielding is serious. Generally, it is between 30KV-50KV.


喷涂距离

Powder coating distance

正常情况下应是100-300mm之间。在实际生产过程中,应根据被喷工件形状,工艺随时调整喷涂距离。

Normally, it should be between 100-300mm. In the actual production process, the spraying distance should be adjusted at any time according to the shape of the workpiece being sprayed.


喷粉量

Powder coating amount

喷粉量一般根据被喷工件的工艺要求及形状而定。在喷箱体里面时应特别注意粉量适当,不宜过大,否则下面会产生堆积。

The amount of powder coating amount is generally determined according to the technological requirements and shapes of the workpiece being sprayed. In spray box, special attention should be paid to the appropriate amount of powder, not too large, otherwise there will be accumulation.


喷角落及沟槽

Powder coating corners and grooves

A.喷涂时先喷角及沟槽,然后喷其他部位。

A. spray the corners and grooves before spraying, then spray other parts.

B.喷涂角及沟槽时应适当调整喷粉射程或减小枪距,并且改变枪的角度和摆动枪。

B. Spraying angle and groove should be properly adjusted to spray range or reduce gun spacing, and change the gun angle and swing gun.

C.可适当调整电压。

C. can adjust the voltage appropriately.


金属粉末喷涂

Metal powder coating

A.应将喷涂状态选择在恒流状态。(选择恒流状态时需调整电压大小)。

A. should select the spray state in the constant current state. (adjust voltage when selecting constant current state).

B.确保粉桶与地面绝缘。

B. ensure that the powder bucket is insulated from the ground.

C.工作时应及时将喷枪和粉管外面及工作手臂上沉积的粉末清理掉。

C. should clean up the powder deposited on the outside of the spray gun and the outside of the powder tube and working arm.

D.经常更换输粉管。

D. often replace the powder delivery pipe.
