Q: What surface treatments are required for Q235 steel used in the medical industry?
A: The core treatment is rust prevention. Common methods include electrostatic spraying, powder coating, painting, and hot-dip galvanizing. Phosphating may be applied to some areas to prevent rust contamination of the medical environment.
Q: What are the common processes used in the manufacturing of Q235 steel for medical equipment?
A: Bending, welding, punching, cutting, and grinding. After welding, weld bead grinding and rust-preventive coating are required to ensure structural smoothness and corrosion resistance.
Q: What are the welding requirements for Q235 components used in medical applications?
A: Arc welding and CO2 gas shielded welding are used. Welds must be full and free of porosity and cracks. Stress relief and grinding are performed after welding to avoid sharp edges and corners, preventing injuries to medical staff and patients.
Q: What are the special requirements for surface coating of Q235 medical components?
A: The sprayed coating must be non-toxic, odorless, washable, and scratch-resistant, meeting the hygiene requirements of a medical environment. The coating thickness should be uniform, with no peeling or paint flaking.
Q: What are the precautions for cutting and forming medical-grade Q235 steel?
A: Cutting dimensions must be precise to avoid deviations affecting equipment assembly. After forming, remove all burrs and sharp edges, and round the corners to prevent mechanical damage.
