The process flow of bucket tooth painting - key points of primer spraying technology

The curing reaction of epoxy primer ‌ : The two-component epoxy resin undergoes a cross-linking reaction with the polyamide curing agent. The gel time at 60℃ is approximately 15 minutes, and complete curing takes 24 hours (the exothermic peak can be detected by DSC differential scanning calorimeter).

Transition layer spraying process ‌ : For flame powder spraying (such as NiCrAlY alloy), the acetylene/oxygen ratio should be controlled at 1:1.2, the powder feeding rate at 15g/min, the spraying distance at 150mm, and the interlayer temperature should not exceed 200℃ to prevent grain coarsening.
