济南护栏去锈、清除氧化皮焊渣的主要方法有手工处理、机械处理、喷射处理、化学处理(酸洗)、电化学处理和火焰处理等方法。

　　The main methods of removing rust and removing oxide slag from Ji'nan guardrail are manual processing, mechanical treatment, jet treatment, chemical treatment (acid washing), electrochemical treatment and flame treatment

　　1、机械处理最常用的有风(电)动刷,除锈枪,抛光砂轮及风(电)铲等工具,借助机械力的高频冲击与磨擦的作用除锈和清除氧化皮旧漆等污物。

　　1, the most commonly used mechanical processing are wind (electric), dynamic brush, rust removal gun, polishing wheel and wind (electric) shovel and other tools, with the aid of mechanical forces of high-frequency impact and friction, rust and removal of oxide, old paint and other dirt.

　　2、手工处理主要使用砂布,刮刀,锤凿、钢丝刷、废砂轮等工具,靠手工打磨敲铲、扫刷来除去锈垢、氧化皮及焊渣,尘土等铁艺护栏表面污物。

　　2, manual processing mainly use emery cloth, scraper, chisel, wire brush, waste grinding wheel tool, polished by hand knock shovel, brush to remove rust, scale and welding slag, dust and other dirt on the surface of iron fence.

　　3、化学处理是利用特殊配方的酸性溶液来浸、溶铁艺制品,通过化学反应来除净氧化皮、锈痕、油污,即所谓的“酸洗”。

　　3, chemical treatment is the use of a special formula of acidic solution to soak and dissolve iron products, through chemical reaction to remove the net skin, rust marks and oil pollution, that is called "pickling"".

　　4、喷射处理是利用机械离心、压缩空气、高压水流等为动力,将磨料、砂石、钢丸抛射到铁艺护栏的表面,冲击和磨擦掉氧化皮、锈痕、旧漆、型砂等。

　　4, injection processing is the use of mechanical centrifugal, compressed air, high pressure water as power, the surface of abrasive, sand, steel projectile iron guardrail, impact and friction off scale, rust, paint, sand and other old scars.
