Five. Methods of use
Slot liquid management: during the process of processing, the total acidity and free acidity of the chemical reaction are reduced, and the total acidity and free acidity are reduced. The total acidity and the free acidity increase by 1 points and 0.2 points in each m3 bath. The concentration of 0.3KG promoter in each m3 slot is up 1. Point. Normal production can be made by adding adjustment to the process area.
This product is packed in 35KG plastic barrel, and it is slightly corrosive to prevent leakage. The shelf life is four years.
