In the process of paint construction, excessive paint in vertical or inclined areas and the formation of top-down flow traces or local film thickening flow falling phenomenon is called flow hanging.
The reasons are as follows:
1) The viscosity of the coating is too low;
2) spit out the amount (also called the amount of paint) is too large;
3) Paint film is too thick;
4) The construction environment temperature is too low, and the air humidity is large;
5) Improper spraying method;
6) The air pressure is too small, and the paint is not well atomized.
Solution:
1) Add thickener to increase the viscosity of the coating;
2) Reduce the spit amount;
3) Increase the production speed and reduce the output;
4) Improve the temperature of the spray room and reduce the humidity of the spray room;
5) Standard spraying method;
6) Increase air pressure.
Short comments: In the process of painting coated drum closure, the phenomenon of stream-hanging may also occur, but the automatic detection machine can directly detect it.
