Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from description, or understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide a kind of anticorrosion treatment technology of motor part.
The anticorrosion treatment technology of the motor part of the present embodiment, mainly comprises:
A, adopt freezing sand-blasting machine, a blasting treatment is carried out to the outer surface of motor part, makes the roughness on the surface of water jacket motor water channel reach 18-23 micron;
After b, a blasting treatment, use the epoxy zinc-enriched paint of slaking, carry out secondary spray treatment; Here, epoxy zinc-enriched paint can be prepared voluntarily, and make the epoxy zinc-enriched paint prepared leave standstill slaking 30 minutes;
The operation of secondary spray treatment, specifically comprises:
Be 1.5-4.5kg/ ㎝ with pressure
2pistol the motor part outer surface after a blasting treatment is sprayed, have the inclination angle of 18 degree between spray gun and coated article surface, rifle mouth is 8-12cm to coated article surface distance; First build is 20 ± 5 μm, after first dry film surface becomes dry, sprays second immediately; Second build is 30 ± 5 μm, after second dry film surface becomes dry, sprays the 3rd road immediately; 3rd road build is 40 ± 5 μm, after the 3rd dry film surface, road becomes dry, is for further processing;
After c, secondary spray treatment, use clear dope, carry out three moppings; After three moppings, in 2-3 minute, stick diaphragm; After sticking diaphragm, carry out low temperature drying, namely complete this preservative treatment.
