PRODUCT DESCRIPTION :

'ZX-9 Zhenxin ®  Epoxy Zinc-Rich Powder Coating ' is a thermosetting pure epoxy powder coating based on the surface spraying of valve pipes, which has high adhesion, high impact resistance and resistance. High chemical properties such as acid and alkali resistance. Heavy anti-corrosion in petrochemical industry has a special effect.

MATERIAL PROPERTIES:

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.
