Example Embodiment

[0024]Example 1

[0025]An anti-corrosion process for bicycle rims includes the following steps:

[0026](1) Perform mechanical treatment on the surface of the bicycle rim, and then degrease the bicycle rim;

[0027]The steps of mechanical treatment of the surface of the bicycle rim are: grinding the surface of the bicycle rim with a grinding wheel, then grinding the bicycle rim with 1200 grit sandpaper, and finally grinding the bicycle rim with 2000 grit sandpaper;

[0028]When degreasing the bicycle rim, place the bicycle rim in a mixed solution of gasoline and 5% sodium hydroxide for immersion. The immersion temperature is 55°C for 12 minutes. After soaking, the bicycle rim is sent to the ultrasonic cleaning machine Carry out ultrasonic cleaning in the middle, ultrasonic cleaning 10min.

[0029](2) Carry out acid wash and deionized water wash on the degreasing bicycle rim in sequence;

Abstract

The invention discloses a bicycle rim anti-corrosion process. The process comprises the following steps that the surface of a bicycle rim is subjected to mechanical treatment, and then the bicycle rimis subjected to oil removal; the bicycle rim subjected to oil removal is sequentially subjected to acid pickling and deionized water washing; and the washed bicycle rim is subjected to plasma treatment. According to the bicycle rim anti-corrosion process, the surface performance of a battery can be improved, the adhesive force of a surface film or paint of the battery can be improved, a compositecoating is sprayed in an electrostatic spraying mode through an electrostatic spray gun, drying and sintering are conducted immediately after spraying, the composite coating sprayed to the bicycle rim can be more uniform, the situation that the composite coating falls off can be avoided, the abrasion resistance and heat resistance of the super-hydrophobic coating can be improved, therefore the composite coating is prevented from being damaged due to abrasion, the service life of the bicycle rim is prolonged, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of bicycle processing, in particular to a bicycle rim anticorrosion process. Background technique [0002] With the development of society and the improvement of people's living standards, great changes have taken place in people's travel methods. Bicycles and electric vehicles have become common travel tools in people's lives. The important structure on bicycles and electric vehicles is the rim. To improve the service life of the rim, people usually carry out anti-corrosion treatment on the bicycle rim. In order to facilitate people to handle the bicycle rim, people invented the bicycle rim anti-corrosion process; [0003] There are certain defects when the existing bicycle rim anticorrosion process is used. First of all, the existing bicycle rim anticorrosion process usually sprays coatings on the bicycle rim, and the existing bicycle rim anticorrosion process spraying effect is not good. The spraying is not even e...
