Achieve many things at one stroke.But in actual production, owing to the chelating agent ability of 1# four-in-one groove is inadequate, take out of medicament 2#,
3#, 4#, 5# groove decompose too fast, each groove cell wall fouling, bother very much during the clear end.
4, water circularly purifying processing system thinking is fine, in-line purification, but product line worker inadaptable complexity behaviour
Make.Equally, existing oxidation line is early the most molded, directly constructs, interpolation equipment on the most wired, and aluminum material factory is very
Difficult acceptance.
5, reverse moisturizing neutralized system had both supplemented liquid level, and by reclaiming medicament, technical concept is the best.But need
The chelating agent cooperation that 1# groove is powerful, could realize.
The problem existed for above-mentioned earlier application file, it has been done and has further studied by applicant, and
The technical scheme of the problems referred to above that achieve a solution.For tradition alkaline etching (as shown in Figure 3), acid etching (such as Fig. 4
Shown in) and blasting craft is complicated, work nest and rinsing bowl is too many, work efficiency is low, dosing is many, waste water is arranged
High-volume big, process fluorine, COD and the drawback that cost is the highest and sandblasting efficiency is the lowest, percent defective is high of ammonia nitrogen,
Take into account Chinese patent 200510101420.X bright acid etching technology for aluminium alloy and Chinese invention patent
201010515738 aluminium alloy four work nest unification medicaments reclaim and wastewater zero discharge surface pretreatment system capable of combining entirely
Pros and cons, the aluminium alloy sand face of custom-designed a set of joint medicine water saving processes technique, also acts the most basic mesh
: joint medicine water saving mesh.
