    摘要： The present disclosure relates to a chemically treated zinc-based plated steel sheet that is superior in weather resistance, water resistance, blackening resistance and film adhesion. A chemical conversion film having a thickness 0.5-10 μm is formed by coating and drying a chemical treatment solution on a surface of an aluminum-containing zinc-based alloy plated steel sheet. The chemical treatment solution contains a fluororesin containing 0.05-5% by weight of a hydrophilic functional group selected from the group consisting of a carboxyl group and a sulfonic acid group and 7-20% by weight of a fluorine atom, the fluororesin in which a number-average molecular weight is 1,000-2,000,000, and an oxoate, a fluoride, a hydroxide, an organic salt, a carbonate or a peroxygenated salt of a group 4A metal.

    摘要： Disclosed is an anti-corrosion treatment method for a heat exchanger, in which even if an aluminum material-made heat exchanger having been flux-brazed by the NB process, in particular, an aluminum material-made heat exchanger to be used for automobile air conditioner is not subjected to a chemical conversion treatment in advance, not only corrosion resistance can be significantly enhanced without impairing hydrophilicity, but deodorizing properties can be enhanced. The anti-corrosion treatment method for an aluminum material-made heat exchanger includes bringing an aluminum material-made heat exchanger having been flux-brazed by the NOCOLOK brazing process into contact with a hydrophilic treatment liquid and then applying a baking treatment, thereby forming a hydrophilic film on the surface of the aluminum material-made heat exchanger, wherein the hydrophilic treatment liquid contains a hydrophilic resin and a lithium ion, and a lithium concentration in the hydrophilic film is from 0.05 to 25% by mass.
