| Question£º |
Uneven coating |
| reason£º |
1, lance and workpiece too close
2, a high voltage electrostatic generator voltage instability
3, powder pellet |
| resolvent |
1, adjust the workpiece and spray distance
2, adjustable high voltage electrostatic generator
3, prevent the powder agglomeration |
|
| |
| Question£º |
Pinhole |
| reason£º |
In 1, the output voltage is high
In 2, the spray gun and work too close
In 3, the coating is too thick |
| resolvent |
In 1, the voltage level
In 2, the spray gun adapted from work
3, strictly control the coating thickness |
|
| |
| Question£º |
Coating surface hardness is insufficient |
| reason£º |
In 1, the baking time or temperature is not enough |
| resolvent |
1, in accordance with the suppliers to provide appropriate temperature curing conditions improve or extend the time |
