1. The commonly used mechanical treatment methods for removing rust and welding slag from aluminum guardrails include wind (electric) brushes, rust removal guns, polishing grinding wheels, and wind (electric) shovels, which use high-frequency impact and friction of mechanical force to remove rust and remove dirt such as oxide skin and old paint.
2. The manual treatment of removing rust and welding slag from aluminum guardrails mainly uses tools such as sandpaper, hammer chisels, wire brushes, scrapers, and waste grinding wheels. Hand polishing, tapping, and sweeping are used to remove surface dirt such as rust, oxide scale, welding slag, dust, etc.
3. The chemical treatment for removing rust and welding slag from aluminum guardrails is to use a specially formulated acidic solution to immerse and dissolve iron products, thereby removing impurities such as oxide scale, rust marks, and oil stains through chemical reactions.
4. The spray treatment for removing rust and welding slag from aluminum guardrails is powered by mechanical centrifugation, compressed air, high-pressure water flow, etc., allowing abrasives, sand, and steel balls to be ejected onto the surface of the aluminum guardrails, playing a role in impact and friction to remove dirt such as oxide scale, rust marks, old paint, and molding sand.
