Description

Zinc aluminium magnesium is alkali wash pond foam breaker for continuous hot dip plating Technical Field The utility model relates to an alkali wash tank defoaming device for zinc-aluminum-magnesium continuous hot dip plating, and belongs to the field of alkali wash tanks. Background Compared with the traditional hot dip galvanizing and aluminizing zinc products, the zinc-aluminum-magnesium product has more excellent corrosion resistance, meanwhile, the zinc-aluminum-magnesium coating has high hardness, the coating is thin and compact, the zinc layer is not easy to peel off in the stamping process, the service time of the die is greatly prolonged, the occurrence of surface defects of stamping is reduced, the zinc-aluminum-magnesium product has more excellent notch and notch protection performance, the zinc-aluminum-magnesium product can still maintain good corrosion resistance in a severe corrosion environment, partial color-coated plates or galvanized products after processing can be replaced, the user processing procedure is simplified, and the zinc-aluminum-magnesium alloy coating product is one of the best energy-saving, material-saving and environment-friendly products in the long term. For the continuous galvanized product of plate area zinc aluminium magnesium, need carry out alkaline wash deoiling pretreatment in alkaline wash pond inside, the alkaline wash pond produces more foam in alkaline wash in-process, and when the water in the alkaline wash pond got into the filter vat, foam gathered at the filter vat top, overflowed easily and caused near electrical equipment or water pump etc. to become invalid, at present mostly through adding the defoaming agent or carry out defoaming treatment through ultrasonic defoaming device to alkaline wash pond, nevertheless add the defoaming agent and can lead to follow-up sewage treatment cost to improve, ultrasonic defoaming device's cost is also higher.
