SPRAYING PROCESS:

1. The high voltage electrostatic spraying method, friction electrostatic spraying method or fluidized bed construction were used in the construction.

2.Electrostatic spraying parameters : baking temperature : 190 ℃ / 15min or 200 ℃ / 10min, electrostatic high voltage : 60-90kv, electrostatic current : 10-20uA, atomization pressure : 0.3-0.45Mpa, spray gun and workpiece distance : 150-300mm, spraying film thickness : 250-500μm.

3.Site spraying pretreatment : shot blasting-grinding-preheating, surface treatment clean, avoid affecting adhesion, preheating temperature 220-250 ℃ / 30min, full degassing, prevent bubbles.

4.The spraying temperature is about 110-140 °C, and the curing temperature is 190 °C -200 °C / 15min-20min.
