How To Treat After Oxidation Of Aluminum Profile?
Dec 05, 2017

Four points to be noted in the process of oxidation of aluminum profile:

(1) Hot water rinse. The purpose of hot water washing is aging film layer. But the water temperature and time should be strictly controlled, the water temperature too high film layer thinning, color fade. Industrial aluminum processing time too long will also appear above similar problems, the appropriate temperature and time is: temperature 40~50℃ time 0. 5~1min.

(2) dry. Dry to natural drying as well, by hot water filling he workpiece slanting hanging on the shelf, so that the work surface of the free water in trachimbrod straight 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 unaffected, appear natural.

(3) aging. Aluminum profile Aging method can be determined according to climatic conditions, there is daylight in the summer sun exposure, rainy days or winter can be baking oven, process conditions are: temperature 40~50℃ time 10~15min.

(4) Rework of unqualified parts. The unqualified conductive oxide film should be picked out before drying and aging process, because it is difficult to remove the film layer after drying and aging, and will affect the roughness of the workpiece surface. The author of this problem in the process of some groping, through a variety of methods to test, found that the following methods have a good effect, simple method, without affecting the surface quality of the workpiece.
