How to deal with the oxidation phenomenon of aluminum profile
Industrial
aluminum profiles are currently used in many industries and are indispensable
processing materials in these industries. However, when we use this material,
we often find that it is not so easy, because of a variety of factors, making
industrial aluminum profile processing is not satisfactory. One of the greater
impact is that industrial aluminum profiles are prone to oxidation phenomenon,
when we face this situation how to deal with it?
1. Aging. Chinese
brand aluminum profile processing industry and non-ferrous metal industry overall
strength continues to improve, has become the worlds non-ferrous metals and
aluminum, aluminum profiles, especially industrial aluminum profile processing
industry, is actively moving towards the world non-ferrous metals and aluminum
industry power. Aluminum profile aging method can be determined according to
climatic conditions, daylight summer can be exposed in daylight, rainy days or
winter can be baked in the oven. The process conditions are: temperature 40 to
50 degrees C time 10 to 15 minutes.
2. Hot water
rinse. The purpose of hot water washing is to age the membrane layer. But the
water temperature and time to strictly control (control),water temperature is
too high film layer thinning, color fade. Industrial aluminum profile
processing time is too long will also appear the above-mentioned similar
problems,the appropriate temperature and time is: temperature 40 to 50 degrees
C time 0. 5 to 1 minute.
3. Dry. Drying to
dry naturally as well, the hot water filling of the workpiece hanging on the shelf,
so that the work surface of the free water in a straight direction down. Flow
to the lower corner of the water beads with a towel to suck away, according to
this method to dry the film layer color is not affected, it appears natural.
4. Repair of non-conforming parts. It is advisable to pick out before the drying and aging process, because the drying, aging membrane layer is more difficult to remove and will affect the roughness of the surface of industrial aluminum profile. First of all, the unqualified industrial aluminum profile is clamped on the fixture used for aluminum anode oxidation, and then according to the aluminum anode oxidation method in the sulfuric acid solution for 2 to 3 minutes, the film layer is soft, shedding, and then slightly cleaned by the lye and ammonia nitrogen water can be re-conducted anodepolarization.
