Abstract

The invention provides a processing method for hot dip galvanizing. Processing steps for a workpiece comprise: 1) degreasing; 2) washing; 3) pickling; 4) washing; 5) dipping with a plating auxiliary; 6) drying; 7) hot dip galvanizing; 8) centrifugal finishing; 9) leaching with an ammonium chloride solution; 10) rinsing; 11) drying of the workpiece; and 12) inspection of the workpiece. The concentration of ammonium chloride is 10 to 15%; pure water is used in the step of washing; temperature of the pure water is maintained at 30 DEG C to 35 DEG C. The processing method provided by the invention improves processing quality and working efficiency and reduces production cost.

Description

A kind of working method of pot galvanize

Technical field;

The present invention relates to the metallic surface working method, especially relate to a kind of working method of pot galvanize.

Technical background:

Galvanizing or galvanizing also are in pot galvanize, are a kind of effective anti-corrosion of metal modes, are mainly used on the metal construction facility of every profession and trade.Workpiece need pass through a series of pre-treatments just can put into zinc bath and zinc liquid reaction generation zinc layer.Traditional processing method, the zinc layer of generation only depends on workpiece surface mostly, zinc layer sticking power a little less than, when product runs into relatively large surging force, cause the zinc pull-up to fall easily, even reduced the solidity to corrosion and the work-ing life of product.

Summary of the invention:

The object of the invention is exactly to provide that a kind of processing quality is good, the working method of the pot galvanize of high efficiency.It can overcome above-described problem.1), degreasing the objective of the invention is to realize like this, a kind of working method of pot galvanize is characterized in that: the procedure of processing of workpiece is following:; 2), washing; 3), pickling; 4), washing; 5), soak plating assistant agent; 6), oven dry; 7), pot galvanize; 8), centrifugal arrangement; 9), soak ammonium chloride solution; 10), rinsing; 11), the drying of workpiece; 12), the check of workpiece.The concentration of described ammonium chloride is 10-15%; What described washing was adopted is pure water; Described pure water temperature remains on 30 degrees centigrade-35 degrees centigrade.

The present invention has improved processing quality and working efficiency, has reduced production cost.

Embodiment:

Be described further in the face of the present invention down:

A kind of working method of pot galvanize is characterized in that: the procedure of processing of workpiece is following:

1), degreasing; 2), washing; 3), pickling; 4), washing; 5), soak plating assistant agent; 6), oven dry; 7),

Pot galvanize; 8), centrifugal arrangement; 9), soak ammonium chloride solution; 10), rinsing; 11), the drying of workpiece; 12),

The check of workpiece.The concentration of described ammonium chloride is 10-15%; What described washing was adopted is pure water; Described pure water temperature remains on 30 degrees centigrade-35 degrees centigrade.During practical implementation, adopt pure water to wash, reduce impurity in the common water, use warm water simultaneously, prevent to cause the workpiece surface cracking because of water temperature is low to the influence of zinc layer; Use whizzer that workpiece is carried out centrifugal arrangement, help removing unnecessary zinc; Workpiece is immersed in the aqueous ammonium chloride solution of 10-15%, can make product appearance more glossy.
