    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.

    摘要: A rust prevention coating agent which can be used even in uses requiring high corrosion-resistant performance because of having corrosion resistance superior to a conventional surface treatment agent, and is excellent in the adhesion to a coating film, and a method of rust-proofing using the same are provided. The prevention coating agent comprises a fluorine and zirconium-containing compound and certain guanidine compounds and/or salts thereof.

    摘要: There is disclosed a rust prevention and hydrophilization treatment method for a flux-brazed aluminum-made heat exchanger which comprises subjecting the same to a rust prevention treatment by the use of a zirconium base compound and/or a titanium base compound, and thereafter subjecting the same to a hydrophilization treatment by means of a hydrophilization treatment agent composition containing the under-mentioned components: (1) 40 to 90% by mass of polyvinyl alcohol having a degree of saponification of at least 90%; (2) 3 to 40% by mass of polyoxyalkylene-modified polyvinyl alcohol in which 0.01 to 20% of pendant groups are polyoxyalkylene ether groups; (3) 1 to 30% by mass of an inorganic cross-linking agent which reacts with hydroxyl groups of the polyvinyl alcohol and modified polyvinyl alcohol; and (4) 1 to 20% by mass of a guanidine compound and/or a salt thereof. The above simplified method dispenses with a flux removal step without causing wastewater treatment problems, and thus assures favorable rust prevention and deodorization effects.
