Title: Drying method of metal
Inventor: YAMAZAKI HIRONORI
IPC: C23G5/036
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent irregularity and stains even when a metal is dried as is water depositing on the metal by treating the metal with a soln. containing a pretreating agent for drying while maintaining the soln. to specified electric conductivity. SOLUTION: A pretreating agent for drying, for example, a soln. containing hydroxyl amine is passed and circulated through an ion exchange resin to prevent accumulation of a nonvaporizing component in the pretreating process for drying. Thereby, production of irregular drying and stains can be suppressed. In this method, it is effective to control the electric conductivity of the treating liquid to a specified range. Usually, the electric conductivity of the soln. is preferably maintained to <=50μS/cm by passing the soln. through an ion exchange resin. Thereby, an ionic nonvaporizing component carried from a washing process or produced by decomposition of the treating agent itself can be effectively removed without losing the treating agent component. Thus, it is not necessary to renew the bath in the pretreating process for drying.
