【Overview】

Electroplating coating industry, in order to increase the plating、surface finish, brightness, adhesion, plating solution conductivity 15uS/cm preparation needed less water, another in the plating rinse is also used when the conductivity 10uS/cm The following water to wash, electroplating industry, including water treatment system prepared plating solution before plating needs water treatment system, recycled metals electroplating rinse water in the rinse water recycling waste water zero discharge system. Usually the system by the ultrafiltration device, reverse osmosis, ion exchange unit, EDI combination of devices to meet the requirements of water quality in electroplating industry。

【Electroplating process】

Acid leaching of copper plating the entire board → → → pattern transfer of acid reflux degreasing → ​​washing → ​​II → II → etching tin → pickling → ​​secondary countercurrent countercurrent rinse → rinse → pickling → ​​two counter graphics copper plating rinse Nickel II → → → washing → ​​acid leaching gold recovery → 2-3 → Pure water washing → ​​drying class

【Classification of plating process】

Acid Bright Copper Plating Electroless Nickel / gold plating tin

【Applications】

Electroplating water applications: plating (gold, silver, plated contact, plastic plating, chrome, zinc) and so with pure water, ultrapure water glass coating by electroplating, ultrasonic cleaning, ultrasonic cleaning with pure water, chemical plating Electrophoresis with pure water or ultrapure water, automobiles, home appliances, building materials, surface coating, cleaning water or ultra pure water, the surface treatment of other requirements, or ultra-pure water with pure water。

【Solutions】

Preparation of super water electroplating technology industry broadly 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 filter beds → → → yin and yang, the mixed bed resin filter pore water points →
2、Two-stage reverse osmosis methods, the process is as follows:
Raw water Raw water pressure pump → → → Multi-media filter activated carbon filter softener → → → precision filter regulator first stage reverse osmosis → PH → intermediate → the second stage tank reverse osmosis (RO membrane surface with positive charge) → Pure water tank → → purification pump water points micropore filter →
3、The use of EDI methods, the process is as follows:
Raw Water Pumps → → raw water pressure multi-media filter activated carbon filter → → → precision filter water softener reverse osmosis machine → intermediate → an intermediate pump water tank → → → EDI system → water points micropore filter
