Phosphate & Borax Coating

Phosphate Section
The QED phosphate section includes a pre-treatment tank, zinc phosphoric acid tank, multiple stage rinsing and borax or lime coating. The stainless steel phosphate tank incorporates a low density flat heat exchange surface and a sloped bottom to simplify sludge removal. The borax or lime tank can be either electrically or steam heated. All tanks are insulated and include covers to minimize heat loss. We can supply both traditional dip tanks and flood weir designs.

The QED phosphate process section includes a pre-treatment tank a zinc phosphoric acid tank and two stage rinsing. The tanks are ruggedly fabricated from stainless steel to minimize corrosion. The phosphate tank incorporates a specially designed sloped bottom to simplify sludge removal.

Rinse Section
After exiting the phosphate section the wires pass through a double stage water rinse. The first stage rinse consists of a recirculating system with a pump and process tray and lower reservoir tank. The final rinse stage is a spray rinse of fresh water thus leaving the wires exceptionally free of phosphoric acid.

Borax System
Our Borax Tank Systems are made to coat the wires with a borax solution in preparation for short term storage or subsequent wire drawing. The wires maintain a level path while passing through a process tray that is supplied with fluid from a lower reservoir tank by means of a cast iron centrifugal pump. Weir blocks are located at each end of the tray to both guide the wires and to maintain the correct fluid level.
