Abstract
A method for enhancing the adhesion of hot plated zinc is characterized in that a current is applied in the immersion plating solvent operation in a process, impurities on the product surface or impurities comprising oil stains and the like in pores of a porous base material are peeled from the base material through counterattacking the current, a plating assistant is utilized to immerse a workpiece in order to well activate the blind corners of the workpiece or the deep pores of the workpiece, so the combination force of Fe and Zn is comprehensively enhanced in the hot zinc plating process, thereby the adhesion of a hot plated zinc layer is enhanced. The method has the following advantage: the applicant of the invention enables the action of the current to be added to the hot zinc plating technology and the action of the current force to be utilized to effectively knock out the impurities in the blind corners on the workpiece surface or in the deep pores in order to comprehensively activate the plating assistant, so the adhesion of the plating layer is comprehensively enhanced.
Description
(1) technical field
The present invention relates to a kind of hot dip technology, relate in particular to a kind of method that strengthens pot galvanize sticking power.
(2) background technology
Pot galvanize also claims galvanizing, is that steel and iron member immerses a kind of method that obtains metal cladding in the zinc liquid of melting.Develop rapidly with high voltage power transmission, traffic, communication career in recent years, more and more higher to the steel part requirement of shelter, the pot galvanize demand also constantly increases.Its production process is: workpiece → degreasing → washing → pickling → wash → soak and help plating solvent → drying and forewarm → pot galvanize → arrangement → cooling → passivation → rinsing → drying → check.Wherein soak plating assistant agent and also claim solvent, can remain on before the immersion plating workpiece and have certain activity and avoid secondary oxidation, be combined with matrix to strengthen coating.Prescription is generally: NH4Cl 100-150g/L, ZnCl2150-180g/L, 70～80 ℃, 1～2min.Play the effect of certain enhancing sticking power, if but the base material hole is more, still can cause poor adhesive force, and surface scalings etc. are bad.
(3) summary of the invention
The object of the invention is to design a kind of method that strengthens pot galvanize sticking power, the scaling of control product surface, and to the good effect of preventing scaling of also playing of the many base materials in space.
Technical scheme of the present invention: a kind of method that strengthens pot galvanize sticking power, it is characterized in that: soaking in technological process helped in the plating solvent operation and added electric current, by the counterattack electric current, make the impurity of product surface or the impurity such as greasy dirt in the porous substrate space peel off base material, utilize simultaneously plating assistant agent submergence workpiece, well workpiece dead angle or deep layer space have all been activated, in hot galvanizing process, well strengthen the bonding force of iron and zinc, thereby strengthened the sticking power of hot galvanized layer.
Superiority of the present invention: my company joins in the hot dip galvanizing process the effect with electric current and goes, and the effect that utilizes electric current power effectively hits dead angle or the deep hole impurity of workpiece surface, makes the plating assistant agent activation more comprehensively, thereby has comprehensively strengthened coating adhesion.
(4) description of drawings
Accompanying drawing 1 is structural representation of the present invention,
Wherein: the 1st, plating assistant agent, the 2nd, cell body, the 3rd, anode, the 4th, cathode bar, the 5th, rectifier, the 31st, iron plate, the 32nd, anode thick stick.
(5) embodiment
Show such as accompanying drawing one: a kind of method that strengthens pot galvanize sticking power, it is characterized in that: soaking in technological process helped in the plating solvent operation and added electric current, by the counterattack electric current, make the impurity of product surface or the impurity such as greasy dirt in the porous substrate space peel off base material, utilize simultaneously plating assistant agent submergence workpiece, well workpiece dead angle or deep layer space have all been activated, in hot galvanizing process, well strengthen the bonding force of iron and zinc, thereby strengthened the sticking power of hot galvanized layer.
Implementation: add plating assistant agent 1 in cell body 2, anode 3 is installed in cell body 2 both sides, anode comprises anode thick stick 32 and iron plate 31, and iron plate 31 is hung on the anode thick stick 32.Workpiece is hung on the cathode bar 4, and with rectifier 5 energising, electric current hits from workpiece surface, with the impurity greasy dirt of workpiece surface etc. is hit in the lump from workpiece surface, thereby plating assistant agent is activated the surface simultaneously fully, when pot galvanize, well strengthened the sticking power of hot-dip coating.
Claims (1)
1. method that strengthens pot galvanize sticking power, it is characterized in that: soaking in technological process helped in the plating solvent operation and added electric current, by the counterattack electric current, make the impurity of product surface or the impurity such as greasy dirt in the porous substrate space peel off base material, utilize simultaneously plating assistant agent submergence workpiece, well workpiece dead angle or deep layer space have all been activated, in hot galvanizing process, well strengthen the bonding force of iron and zinc, thereby strengthened the sticking power of hot galvanized layer.
