The uneven appearance of the paint coating, which resembles the peel of an orange or walnut, is called orange peel.
The reasons are as follows:
1) The construction viscosity is too high and the paint film leveling is poor;
2) Improper selection of spray gun;
3) High temperature and low humidity in the spray room;
4) Insufficient leveling time and premature entry into the drying room;
5) Spraying film is too thick or too thin
Solutions:
1) Add pure water to adjust the coating viscosity;
2) Standardize the spray gun, or adjust the spraying distance, fan width, etc.;
3) Reduce the temperature of the spray room, improve the humidity of the spray room;
4) Increase leveling time;
5) Adjust the amount of spit and gun speed to prevent the paint film thickness beyond the specified range.
Short comments: in the process of painting epoxy phenolic drum closures, the orange peel probelm will also occur, but with small probability, we will check each closures for customers.
