Q: What are the surface coating options for the DX51D, suitable for medical applications?
A: Epoxy powder coating, PU coating, and antibacterial coating are preferred; they must meet medical-grade non-toxic and sterilization-resistant requirements, and avoid using primers containing heavy metals.
Q: How does the DX51D achieve aseptic compatibility?
A: It cannot achieve sterility on its own; it requires "surface coating + post-treatment": the coating must be heat-resistant and sterilized, and the component must be sterilized with ethylene oxide after molding, and it should only be used for disposable or reusable peripheral parts.
Q: Will welding affect the corrosion resistance of the DX51D?
A: Yes. The high temperature of welding damages the local zinc layer, making the weld seam prone to corrosion; after grinding the weld seam, a zinc-rich primer + topcoat should be applied to restore corrosion resistance.
Q: How to prevent edge corrosion of stamped parts of the DX51D?
A: Remove burrs and sharp edges after stamping; apply passivation treatment or edge sealing coating to prevent moisture from seeping into gaps and accelerating corrosion.
Q: What is the surface treatment process for medical-grade DX51D components?
A: Degreasing of substrate → Pickling → Hot-dip galvanizing → Passivation (to improve the corrosion resistance of the zinc layer) → Spraying of medical-grade coating (such as epoxy) → Curing → Sterilization test.
