Zinc flake coating equipment occupies an important position in modern industry. Zinc flake coating is very common in production, but zinc flakes cannot be stored at high temperatures, why?
Since high temperature tends to lead to aging of paint solution, the storage temperature of zinc flake paint solution should be controlled at 10°C. Meanwhile, in the sunlight, the paint is easy to polymerize, discolor or even scrap, so it is better to keep the light in the shade. The storage period of zinc scale coating should not be too long, because the longer preparation time for the liquid coating solution, the pH value is more likely to rise. Finally causing the liquid coating aging, or even been scrapped. The experiment shows that after preparing the validity of 20 ℃ for 30 days, there is no waste chromate waste, the temperature of 30 ℃ is effective in 12 days, the temperature of 40 ℃ is only effective in 5 days.
The zinc flake coating solution must exist at low temperatures; high temperatures will cause the liquid coating to age.
