Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
Fig. 1 is the preparing method's of embodiment of the invention ferrous products zinc-nickel coating process figure.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Fig. 1 is the preparing method's of embodiment of the invention ferrous products zinc-nickel coating process figure; This preparation method comprises the steps: a) preparation compo, b) ferrous products pre-treatment, and the c) coating of coating, d) induction heating is handled, e) ferrous products aftertreatment.
Embodiment
The preparing method's of the ferrous products zinc-nickel coating that the present invention mentions concrete preparation process is following:
A) preparation compo, the major ingredient of coating is: 60% zinc powder, 35% nickel powder, 3% cobalt powder and 2% chromium powder, coating also need add suitable auxiliary material in the preparation process, and the staple of auxiliary material is: rust-preventive agent, promoting agent, suds suppressor and thinner; Wherein, rust-preventive agent selects for use Zinc aluminate, promoting agent to select for use silicone oil, suds suppressor to select silicone antifoam agent for use, and thinner is a deionized water, and the per distribution ratio of auxiliary material is about 1:1.5:3.5:20; The per distribution ratio of above-mentioned major ingredient and auxiliary material is about 1:8; During use, major ingredient and auxiliary material be added in the lump carry out in the reaction kettle mechanical stirring fully after, subsequent use;
B) ferrous products pre-treatment, the ferrous products pre-treatment comprises sandblasting and skimming treatment; Wherein, sandblasting can improve the fatigue resistence of ferrous products, has increased the sticking power between ferrous products and the coating, prolongs the weather resistance of filming, and it is the silica sand about 200 orders that the sandblast raw material is selected granularity for use, and blasting pressure is controlled at 0.5MPa; The slightly acidic degreaser is used in skimming treatment, and degreaser concentration is 8%-10%, and solution temperature is controlled at about 30 ℃, adopts ultrasonic cleaning, and the back that disposes is with flushing with clean water and dry;
