In the face of industrial aluminum profile oxidation solution

Industrial aluminum profiles are commonly used in many industries. But during production, it wasn't so easy. Usually, the shape of aluminum alloy is not perfect due to various factors. Among them, aluminum alloy profiles are easy to oxidize, which is a headache.

Faced with this situation, how should employees deal with it?

(1) Aging. The aging method of aluminum alloy profiles can be determined according to the climatic conditions. It can be exposed to the sun on sunny days in the summer, or baked in the oven on cloudy days or in the winter. Process conditions: temperature 40℃, 50℃, time 10~15 min.

(2) Rinse with hot water. The purpose of hot washing is to age the film. However, water temperature and time should be strictly controlled, water temperature is too high thin film, light color. Industrial aluminum profile processing time is too long will also appear the same problem, the appropriate temperature and time is: temperature 40~50℃, time 0.5 min.

(3) Dry. It is best to dry and dry naturally. The workpiece filled with hot water is tilted on the shelf so that the free water on the working surface flows down in a straight line. Water droplets flowing into the lower corner are caught in a towel, and the color of the film dried in this way is not affected and looks natural

(4) Repair of unqualified parts. It should be removed before dry aging, because it is difficult to remove the film after dry aging, will affect the surface roughness of industrial aluminum profiles. The author makes some explorations on this technique. Through a variety of experimental methods, it is found that the following methods are effective, simple and does not affect the surface quality of the workpiece. The specific process is as follows: First of all, the unqualified industrial aluminum profiles are clamped on the aluminum anodizing fixture, and then the aluminum is anodized for 2-3 minutes in the sulfuric acid solution, and the film is treated with the aluminum anodizing method in the sulfuric acid solution. Soft and peeling, it can be re-anodized after a little cleaning with alkali and nitric acid
