Shelves of the lacquer that bake in the production process, sometimes found after drying coating appearance of many a half-circle bumps on the surface of the lacquer that bake, ripples like orange peel, this phenomenon is often referred to as orange peel, paint coating of orange peel phenomenon is due to the coating caused by the poor flowing property, poor flowing property with itself and the spray paint construction undeserved wait for a variety of factors, in order to prevent the generation of orange peel, in construction should be paid attention to:
1. It is better to handle the bottom layer of the counter display panel. Sealing the white blank with closed paint will help the leveling.In addition, the coating should be fully polished and smoothed, so that it must reach a certain degree of smoothness, so as to ensure the consistency of the coating and the foundation of the coating.
2. Ensure that the viscosity is not too large when spraying.
3. Ensure that the drying table is not too fast after spraying, and the ambient temperature should not be too high (generally around 200C), and can not be dried immediately after spraying.
4. Ensure the flow time after spraying, and the wind speed of the drying room should not be too large in order to maintain the proper temperature of drying room. Otherwise, it will accelerate the evaporation of the solvent and shorten the time of the coating.
5, ensure that after spraying, flowing property and ensure that each coating has a certain thickness, also cannot too thin, too thin or too thick will result in orange peel phenomenon, suggested that each coating thickness control in 5-30 microns.
6, the influence of other factors, such as coating low boiling point solvent content on the high side, construction, solvent evaporation fast, film forming material to flow leveling and formation of orange peel, this kind of circumstance, can take appropriate way to thinner or more appropriate to add some high boiling point solvents to prevent the generation of orange peel phenomenon.In addition, the coating itself is not mixed with curing agent or diluent, and it also produces orange peel phenomenon.
The counter display case that has already appeared orange peel phenomenon is tight because of time, can not be in time, can use fine sand paper to polish the surface of paint film, after polishing treatment can.
