Below by embodiment, technical scheme of the present invention is described in further detail.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide the method for anticorrosion treatment of motor part.
The method for anticorrosion treatment of the motor part of the present embodiment, mainly comprises:
A, employing suction-type dry blasting machine, carry out a blasting treatment to the outer surface of motor part, makes the surperficial roughness of water jacket motor water channel reach 18-23 micron;
After b, a blasting treatment, use the slaking epoxy zinc-enriched paint of 20-30 minute, carry out secondary spray treatment; Here, can prepare voluntarily epoxy zinc-enriched paint, and make the standing slaking of epoxy zinc-enriched paint for preparing 30 minutes;
The operation of secondary spray treatment, specifically comprises:
With pressure, be 1.2-4.5kg/ ㎝
2the motor part outer surface of pistol after to a blasting treatment spray, between spray gun and coated article surface, there is the inclination angle of 22 degree, rifle mouth is 6-15cm to coated article surface distance; First build is 40 ± 5 μ m, after first dry film surface becomes dry, sprays immediately second; Second build is 60 ± 5 μ m, after second dry film surface becomes dry, and Pen tri-roads immediately; San road build is 80 ± 5 μ m, after San road dry film surface becomes dry, and Pen tetra-roads immediately, Si road build is 10 ± 5 μ m;
