Title:

PRECOAT FIN MATERIAL AND ITS MANUFACTURING METHOD

Document Type and Number:

Japanese Patent JP2023009820

Kind Code:

A

Abstract:

To provide a precoat fin material which can be manufactured by a simple process, and is excellent in corrosion resistance and hydrophilicity, and its manufacturing method.SOLUTION: A precoat fin material 1 has a base material 2 and a resin membrane 3 formed on the base material 2. A mass of the resin membrane 3 per unit area is equal to or larger than 0.2 g/m2 and equal to or smaller than 2.5 g/m2. The precoat fin material 1 has a feature that an average value up to a one-hour lapse time point from a natural potential measurement start point which is measured in a 5-mass% NaCl water solution of pH3 becomes equal to or larger than +0.040 V and equal to or smaller than +0.2 V with respect to an average value of the natural potential of the base material 2, and a water contact angle after being immersed in flowing water for 10 min becomes equal to or larger than 20° and equal to or smaller than 40°.SELECTED DRAWING: Figure 1
