How To Do High Quality Garden Tools Rust

  • How do high quality garden tools remove rust stains?

    1.Manual rust removal

    Manual derusting is the most primitive method of descaling. Using abrasive cloth, sandpaper, scraper, wire brush, hammer chisel and other tools, manual shovel, sanding, scraping and sweeping to remove rust, scale and impurities. Things.

    2, machine city polishing

    Mechanical grinding is the removal of the rust layer by the action of impact and friction by means of mechanically driven forces. For example, sand cloth, sandpaper, abrasive paste, wire brush, etc. are fixed on the wheel, and the wheel can be ground and polished in the rusted portion of the metal to remove the rust.

    3, roller derusting

    The rust removal of the drum is to place the metal workpiece and the cast iron casting without the irregular angle and the external thread in a slow-rotating hexagonal or circular drum. Due to the rotation of the drum, the rust is removed by the action of friction and rolling. And dirt such as scales.

    4, flame derusting

    Flame descaling is suitable for the derusting of steel structures with a certain thickness and the surface of castings. The principle is to use the difference between the thermal expansion coefficient of metal and oxide scale. After heat treatment, the scale will rupture and the rust will be dehydrated due to heating. The rust layer is broken and loose.

    5. EDM rust removal

    EDM rust removal is the use of different electrical conductivity and thermal expansion rate of scale and steel to remove rust. The metal workpiece to be cleaned is used as one electrode, and the round roller is used as the other electrode. When the round roller contacts the workpiece, a short circuit is generated to separate the scale, and the rust is separated from the surface of the workpiece by mechanical impact.

    The above is the method of high quality garden tools to remove rusty rust stains, hope to help you.
