配制方法：	Operating Conditions: Bath temperature 180-212F Immersion time 3-10 min. Clean until no water break occurs in rinse. Comments** For average type soil removal and prior to chemical treatment and electroplating. In electrolytic cleaning, parts are cathodic; current density 10-50 amp/ft^2 and 6 volts dc. Use steel tanks, maintain pH above 11.0. **Anodic cleaning not recommended; undesirable oxide and hydroxide surface films will form, and surface pitting may occur from prolonged cleaning. *Cleaners containing more than 2% sodium hydroxide (NaOH) will attack ZK60A, ZK60B and some magnesium-lithium alloys with a resultant decrease in dimensions.
