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.

摘要： In a heat exchanger having tubes and fins, a polyaniline film made of polyaniline and/or a derivative thereof is formed on the surfaces of the tubes and the fins. This polyaniline film is imparted with at least one hydrophilic functional group selected from the class consisting of a primary amino group, a secondary amino group, a tertiary amino group, an ammonium group, a nitric acid group, a carboxyl group, a sulfonic acid group, a phosphonic acid group and a hydroxyl group. Accordingly, the surfaces of the tubes and the fins has good water wettability while maintaining deodorizing and sterilizing functions.
