After cold/hot-dip galvanizing, solar street light poles hardly rust (except for trachoma during welding), so the factor that affects the aesthetics of street lights is the exterior paint. After galvanizing, the final anti-corrosion coating process for solar street light poles is plastic spraying. The plastic powder used in the spraying is used in the field, which has the characteristics of high hardness and strong adhesion. Although the appearance and anti-corrosion effect of the lamp post after spraying have been further improved, it is found that its service plastic powder is not effective. The lifespan cannot reach 10 years, let alone 15-20 years. Take a good high-gloss plastic powder, the lamp post after spraying the plastic is smooth and clean, however, after three years of outdoor use, the luster of the solar street light pole will gradually disappear, and then begin to change color and fall off. painting. This is a good plastic powder, a poor quality plastic powder will completely change within a year. The disadvantage of outdoor plastic powder is poor aging resistance.
It is necessary to prolong the service life of the surface paint of street lamps, so that it can keep the original color for a long time without fading and chalking. If galvanizing is for rust prevention, plastic spraying is for beauty. If the rust prevention measures are done and the aesthetics are achieved, the protective film will be perfect. The powder has poor weather resistance in the field. If it can be encapsulated with a super weather resistant exterior paint, it can retain its properties for a long time. It is “fluorocarbon paint”. Fluorocarbon paint has the characteristics of excellent anti-corrosion performance, maintenance-free, strong adhesion, and long weather resistance. Coating fluorocarbon paint on the outer layer of plastic powder for solar street light poles can play a good protective role, which is not the case. The problem of keeping exterior paint shiny for over a decade.
