How to deal with the oxidation of insulation aluminum plate?
Mingtai Aluminum insulation aluminum plate is mainly 1000 series aluminum plate, including 1050 aluminum plate, 1060 aluminum plate etc. When using the insulation aluminum plate, we may encounter the situation of oxidation of insulation aluminum plate. So how to deal with this problem?
1, hot water rinse. Hot water wash is aimed at aging the film. But the water temperature and time to strictly control the water temperature is too high film thinning, color fades. Industrial insulation aluminum processing time is too long will appear the above similar problems, the appropriate temperature and time is: temperature 40 ~ 50 ℃ time 0.5 ~ 1MIN.
2, dry. Dry to dry naturally as well, by the hot water of the workpiece oblique hanging on the shelf, so that the surface of the free water to the vertical direction of the downward flow. Flow to the lower corner of the water droplets with a towel to absorb, according to this method to dry the film color is not affected, it is natural.
3, aging. The aging method of thermal insulation aluminum can be determined according to the climatic conditions. The sun can be sun exposed in the sun, rainy days or winter can be oven baking, the process conditions are: temperature 40 ~ 50 ℃ time 10 ~ 15min.
4, unqualified pieces should be repaired. Unqualified conductive oxide film should be in the dry, aging process before picking out, due to dry, aging film more difficult to withdraw and affect the surface roughness of the workpiece. We can first unqualified workpiece folder in the aluminum anodizing fixture, and then in the sulfuric acid solution in the anodic oxidation method for anodic treatment 2 ~ 3min, to be loose layer, shedding, and then a little lye cleaning And nitric acid light can be re-conductive anodized.
