Maintenance:
MX-ZN610-L replenishment is in proportion to the treatment
area;
Add 1L MX-ZN610-L
(MX-ZN610-LA & MX-ZN610-LB) every time deal with 2000dm2plating pieces, there is a discrepancy according to product
requirement and input;
As for barrel plating, input is large, increase the amount of
MX-ZN610-L replenishment properly to keep passivation’s concentration and great
corrosion;
