The spraying system has the characteristics of good degreasing effect, more uniform chemical film formation, shorter processing time and high production efficiency.

But spray to consider more comprehensive factors, only the correct choice of spray equipment, in order to give full play to the performance of pre-treatment agents, to obtain high quality pre-treatment effect.
