Elektroforetisk aluminium er aluminiumoxidet som anoden, placeret i vand-opløselig emulsionsopløsning gennem jævnstrøm, kunstigt aflejret på overfladen af aluminiumoxidfilmbelægningsfilmens beskyttende lag for at danne elektroforetisk aluminium.
Hovedegenskaber ved høj-elektroforetisk aluminium:
1. Det har en stærk malingsfilmhårdhed.
2, med høj vedhæftning film, ikke let at falde af aldring.
3. Det har stærkere vejrbestandighed og alkalibestandighed end aluminiumoxid.
4, overfladefarven er rig, smuk, med spejl--lignende glanseffekt.
Elektroforetiske profiler er mere velegnede til brug udendørs, den nationale standard 70 års vejrbestandighed grundlæggende sekund dræber andre overfladebehandlinger.
Electrophoretic profile packaging materials are mostly used for strong adhesion film as a protective film, aluminum profiles in a protective film for a period of time, the film is torn to find that aluminum profiles have film printing or called watermark. There are two kinds of watermarks: one is volatile watermarks, which will disappear after a period of time after the film is torn. The two are non-volatile watermarks, which do not disappear after tearing the film for a year or two. The situation of volatile watermarking almost all aluminum plants have appeared.

The situation of volatile watermarks has appeared in almost all aluminum factories, and there are two kinds of watermarks: one is volatile watermarks, which will disappear after a period of time after the film is torn. The two are non-volatile watermarks, which do not disappear after tearing the film for a year or two. The situation of volatile watermarking almost all aluminum plants have appeared.
Film watermarking is a common phenomenon, film such as air separation, and moisture formation, which has been recognized in the industry. Many factories have also done a large number of relevant experiments. There are several considerations:
1 størkningsproces eksperiment
180 degrees 30 minutes basically appear watermark boundary, 200 degrees 10 minutes effect is also better than 180 degrees 30 minutes effect. So the temperature and time is quite key, especially in the case of heat will fade the coloring way, must be integrated to weigh the curing process and color.
2 beskyttende film viskositet og vandspray eksperiment
There were watermarks 24 hours after spraying film for both high viscosity and medium viscosity, while there were almost no watermarks 24 hours after spraying film for low viscosity. It shows that the viscosity of the membrane has a great relationship. But there is a phenomenon, if sprayed with pure solvents such as alcohol, there is no watermark on any viscosity. The author cannot find a reasonable explanation for this phenomenon. I'll leave that to the right person.
3. Problemer med elektroforesetankopløsning
Ovenstående er kun fra analysen af resultaterne, men måden at håndtere problemet på i en anden fabrik får forfatteren til at genkende retningen af det grundlæggende problem.
It is also a watermarking problem, but the delivery is urgent, and the change of low viscosity protective film is not guaranteed to be a problem, but also to observe the time. The workshop director decided to rearrange the electrophoresis tank. (Pull out to empty slot, can be added later). The process was not changed and the problem disappeared. I can't remember any new grooves having similar problems.
Det følgende er kun en slutning. Udstyret, der ejes af forfatteren, kan ikke understøtte verifikation på nuværende tidspunkt.
In electrophoresis, only the solvent can not be tested. It can be inferred from the above phenomenon that the solvent is reduced, and the principle of recovery equipment is to filter water and solvent from the main tank to water washing, and the solid components of water washing return to the main tank, and achieve the purpose of recovery. The volatile nature of the solvent and the lack of laboratory equipment, resulting in the failure to quantify the proportion of solvent imbalance.
Ubalancen af opløsningsmiddel kan forårsage skade på malingsfilmens kompakthed og ensartethed og få vand til at trænge ind i malingsfilmen, hvilket resulterer i dannelsen af vandmærke.
Opsummer de ovenstående tre punkter, håber lignende tilfælde kan sammenlignes for at finde problemet.
