Plating coating pure water equipment System OverviewWe see on the road with various brands of cars, their smooth and pretty fun to watch. These are derived from the plating coating process of the car, on the surface of the alloy plating layer can prevent corrosion and oxidation. This requires the use of pure water to remove surface dust, electroplating coating industry in order to increase the plating surface finish, brightness, adhesion of the preparation, the need for plating solution in water by conductivity 15uS / cm-5uS / cm or less, also in the plating rinse is also used in the conductivity 10uS / cm or less water to clean, in addition to ultrafiltration and reverse osmosis can also be used to recover rinse precious metal ion penetration over the water and then returned for plating cleaning purposes.Plating coating pure water equipment system processProcess for preparing coating and electroplating industry water roughly divided into the following categories:1, the use of ion exchange, the process is as follows:Raw water → raw water pressure pump → Multi-media filter activated carbon filter → → → precision filter → softener cation resin anion resin filter bed → → yin and yang resin filter bed mixed bed → microporous filter → water points2, two-stage reverse osmosis methods, the process is as follows:Raw water → raw water pressure pump → Multi-media filter activated carbon filter → → → precision filter → softener first stage reverse osmosis → PH adjustment → intermediate tank → second stage reverse osmosis (RO membrane surface with positive charge) → purified water tank → pure water pump → → water points micropore filter3, the use of EDI methods, the process is as follows:Raw water → raw water pressure pump → Multi-media filter activated carbon filter → → → precision filter water softener reverse osmosis machine → intermediate → an intermediate pump water tank → → → EDI system → water points micropore filterThe international community has already developed the e
