What is the processing technology for the shell of Q235 steel medical equipment?
Process: Cutting (laser/plasma) → Bending → Welding → Grinding → Surface treatment (phosphating + powder coating) → Assembly, ensuring sealing and flatness.
What are the welding precautions for Q235 steel medical structural components?
Use arc welding/CO2 shielded welding, control welding deformation, grind the weld seam smooth to avoid stress concentration, and perform rust prevention treatment after welding.
What are the bending process requirements for Q235 steel medical equipment?
Bending radius ≥ 2 times the plate thickness to avoid cracking; complex shapes should be bent multiple times to ensure dimensional accuracy and structural strength.
What is the surface pretreatment for Q235 steel medical applications?
Rust removal (sandblasting/phosphating) → degreasing → passivation are mandatory to ensure coating adhesion and prevent rusting and peeling during use.
What are the coating process requirements for Q235 steel medical equipment? Powder coating thickness 60–120μm, adhesion ≥ Grade 1, resistant to alcohol/chlorine disinfectant wiping ≥ 100 times without peeling, antibacterial coating preferred.
