CAMELSTEEL will analyze the mass defect cause of color coated galvanized plate.
1. Creeping and grow dim.
Creeping is a uniform color that separates from the paint system. Grow dim is due to two or more colors which did not solve the problem caused by scattered.
Solve measures: Try to stir the workpiece tray without day and increase the painting speed. Try to reflux the paint, change the quarrel and overflow’s position and the overfall pattern will be changed.
2.Bubbles or pinholes.
During the production process, the high speed stir produce bubbles while velocity mixing. And during the wet film coating process, the bubble will rupture and produce pinhole or popping.
Solving methods: During the compound process, please put in some defoamer to decrease the bubbles. Or it is good to adjust the solvent proportion, try to increase the high boiling point solvent proportion, adjust the furnace temperature and cut down the first-void temperature.
