Embodiment 1

[0036] A guitar surface electrostatic spraying process, comprising the following steps:

[0037] S1. Use a sander to scrub the surface of the guitar, and then clean up the wood chips and dust accumulated on the surface of the board by vacuuming; Air dry the surface and set aside;

[0038] S2. Put the guitar treated by S1 in a microwave box for microwave treatment, and take it out when its water content reaches 4%; then transfer it into an arc-shaped corona field generator, and perform arc treatment Corona field treatment, take out the board after 3min, and set aside;

[0039] S3, scrape conductive putty or smear a layer of conductive primer on the surface of the guitar after corona treatment, and make the conductive putty or conductive primer dry under natural conditions; then carry out sanding treatment to the surface of the guitar, so that Its surface is relatively smooth and dense, without pores;

[0040] S4, spray primer on the surface of the guitar obtained after the t...

Abstract

The invention relates to the technical field of guitar production, in particular to a guitar surface electrostatic spraying technology. Before guitar surface paint spraying, scrubbing treatment, microwave treatment, surface active agent wiping and corona treatment are sequentially conducted on the guitar surface, and some novel hydroxide radical, carbonyl, amidogen and other polar functional groups and surface free radicals are generated on the guitar surface, guitar surface wetting and interface bonding are facilitated through the groups, and accordingly, the guitar surface gluing quality iseffectively improved. During finishing coat spraying, the electrostatic spraying technology is adopted, it can be guaranteed that powder in the finishing coat can be evenly and firmly sprayed to the guitar surface, and the electrostatic spraying quality is ensured; and in addition, through setting of the electrostatic spraying voltage, the phenomenon of stream of electrons can be effectively reduced, and it is guaranteed that the appearance of a coating formed on the guitar surface is good.

Description

technical field [0001] The invention relates to the technical field of guitar production, in particular to a guitar surface electrostatic spraying process. Background technique [0002] Guitar, also translated as guitar or violin, is a plucked string instrument, usually with six strings, similar in shape to a violin. The guitar is often regarded as the main instrument in pop music, rock music, blues, folk songs, and flamenco. In the field of classical music, the guitar is often performed as a solo or duet; of course, in chamber music and orchestral music, the guitar also plays a considerable role as a foil. [0003] According to different structures and sound principles, guitars can be roughly divided into three types: acoustic guitar (folk / fingerstyle guitar, flamenco guitar), electric guitar (such as standard electric guitar and bass electric guitar) and classical 6-string guitar (classical guitar). kind. The surface of the guitar needs to be painted during the producti...
