 ◉ Flux Processing
          It removes impurities on the iron surface, removes zinc oxides on the 
          skin plating water surface, and prevents the product surface from oxidizing. 
          The temperature takes about 80℃ to 5 minutes.

            (Plating)
            → Month1,000Ton per 300~500kg additional
            → Month1,000Ton In production approximately 300~600kg
            → Month1,000Ton In production approximately 400~600kg
            → Month1,000Ton In production approximately 500~700kg
Provided, That at this time, the concentration of flux is maintained when supplementing water is injected due to consumption of liquid (Zinc Chloride ammonia)
 - Conditions for Flux
            → Temperature : 65~75℃
            → Composition: Ratio of weight of zinc chloride and
            ammonium chloride (approximately1:1.17)
            → Concentration : 15~40Be°
          
            Excessive iron content increases the effectiveness of the 
            dross and the penetrator decreases.
            - The increase in chloride ions is associated with a decrease in pH 
            because it means the inflow of acid.
            - When the ash is not easily removed from the cooling tank, sprinkle 
            ammonium chloride at a rate of approximately 120kg per ton of plating.
            - There is a unique smell of its own, but the smell of the surfactant 
            itself does not have a significant impact on the human body.
 * Maintain surface tension at 30dyne/cm
            - Add NT5181-3g/L to the Fluxtank.
            - Flxu : ZnCl₂, NH₄ solution 사용.
            - Add NT-518 in case of Zn bounce during melting plating.
 * Use pH 4.0 to 6.0
            - Maintain pH between 4.0 and 6.0 using ammonia water.
            - If the pH reaches 2.0, we recommend a reconstruction bath.
 * 1.0% Fe (keep below 10g/L)
            - When Fe concentration exceeds 1.0%
            Splashing may occur in the molten galvanized tank.
