Problems solved by technology

Metal parts are an important component of power-assisted bicycles. During processing, they often need to be printed to improve their appearance. However, due to the nature of metal parts in actual use, their chemical stability is high, and they are not easy to be penetrated by ink solvents and Dissolution, the combination with ink printing is very low, so it must be surface treated before printing
Currently, there is little research on this

Abstract

The invention discloses a method for improving the surface printability of a metal part of a moped bicycle, which belongs to the technical field of metal material treatment and comprises the following steps of: (1) heating ionization treatment; (2) flame treatment; (3) electron beam irradiation-laser shock wave coupling treatment; and (4) cryogenic treatment. According to the metal part treated through the method, the viscosity, 60-degree glossiness, tinting strength and rubbing fastness of ink of the metal part are all remarkably improved, the adhesiveness of the ink is good, that is, the metal part is used for manufacturing the moped bicycle, the surface printability of the moped bicycle is remarkably improved, and the quality of the moped bicycle is improved to a great extent.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a method for improving the surface printability of metal parts of a mobilized bicycle. Background technique [0002] Power-assisted bicycle is a new type of two-wheeled vehicle, which belongs to a type of bicycle. It uses batteries as the auxiliary power source, is equipped with a motor, and has a power assist system. It can realize the integration of human riding and motor-assisted driving. Metal parts are important components in power-assisted bicycles. They often need to be printed to improve their appearance during processing. However, due to the nature of metal parts in actual use, their chemical stability is high, and they are not easy to be penetrated by ink solvents and Dissolution, the combination with ink printing is very low, so it must be surface treated before printing. Currently, there are few studies on this aspect. Contents of the ...
