An object of the present invention is to provide a surface treatment method for an aluminum plate for a heat exchanger that does not impair pressability and mold wear resistance.

Surface treatment of aluminum for heat exchanger 4-10,000 tons without treatment for 1 hour.

動電が腎られているが、表面は埒4水1(1である。As mentioned above, the conventional chemical conversion coatings 1 and 11 used on aluminum are chromium-based coatings, and have a good electrodynamic effect for surface corrosion resistance of +41 and -1 for improving paint film adhesion. The surface is 4 water 1 (1).

金型摩耗も、Qζ処理の7/ルミニウム材と(はぼ同等
であることを児い出した。In addition to this, the present inventors have applied Jζ1 to the sil-1 nium salt treatment that has recently been used in the chemical conversion coating treatment of IJi materials.
The resulting film has good hydrophilicity and corrosion resistance. Also, the fin press molding (!l)a 1flJ does not occur.
The mold wear was also found to be approximately the same as that of Qζ-treated 7/luminium material.

る皮1漠の密着性が極めて良いためど考えられる。The reason for the good hydrophilicity of the chemical conversion coating that is soaked in the zirconium salt solution is the chemical conversion coating I+! ,! It is presumed that this is because many hydroxyl groups are oriented on the surface, and the reason why the pressability of the treated material is good and there is little mold wear is due to the 71% concentration in the film.
・The diameter is 30 m g7') 2 (The amount of film is c150
This is thought to be due to the fact that it is only about m (1/m2) and the adhesion of the skin to the surface of the material to be treated is extremely good.
