The metal surface treatment of Jinan Iron Gate accessories refers to the whole process of coating, brushing and spraying the surface of iron gate accessories, which exceeds the antirust treatment and the actual effective decoration design of Arts and crafts, in order to avoid the rust on the surface of iron gate accessories and remove and cover the surface defects of iron accessories.

为了确保抗锈及装饰设计实际效果超过尽量长期的目地，必然性地要采用很多相对的表层工艺处理和中后期对施工技术及原材料挑选。

In order to ensure that the actual effect of rust resistance and decoration design exceeds the long-term goal as far as possible, it is inevitable to adopt many relative surface treatment processes and the selection of construction technology and raw materials in the middle and later stages.

一、铁艺大门配件制品表面的处理

1、 Surface treatment of iron gate accessories

为了确保装饰设计喷漆层与铁艺配件工艺品表层有优良的结合性，务必在喷漆执行以前，对铁艺大门配件工艺品表层的空气氧化皮、焊穿、锈痕、植物油脂、脏污、水分开展尽量的消除，不然易导致喷漆层出泡、裂开、起层及脱落等状况。所谓处理是指使用机械或化学、电化学等技术方法在喷涂前消除熟铁产品的表面缺陷。

In order to ensure the excellent combination between the decorative design painting layer and the surface of iron accessories and handicrafts, it is necessary to eliminate the air scale, welding through, rust marks, vegetable grease, dirt and moisture on the surface of iron gate accessories and handicrafts as much as possible before painting, otherwise it is easy to cause blistering, cracking, peeling and falling off of the painting layer. The so-called treatment refers to the use of mechanical or chemical, electrochemical and other technical methods to eliminate the surface defects of wrought iron products before spraying.

1、除铁锈、消除空气氧化皮焊渣的关键方式 有手工制作解决、机械设备解决、喷涌解决、有机化学解决（酸洗钝化）、光电催化解决和火焰处理等方式 。 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，尘土等表面污物。

1. The key ways to remove rust and eliminate air scale welding slag include manual production, mechanical equipment, gushing, Organic Chemistry (pickling and passivation), photocatalysis and flame treatment. Manual treatment mainly uses abrasive cloth, scraper, hammer chisel, steel wire brush, waste grinding wheel and other tools, and uses manual grinding, chipping and brushing to remove rust, scale, welding slag, dust and other surface dirt.

机械设备解决更常见的有风（电）动刷，防锈处理枪，打磨抛光沙轮片及风（电）铲等小工具，依靠机械设备力的高频率冲击性与摩擦的功效防锈处理和消除空气氧化皮旧漆等废弃物。

The most common problems solved by mechanical equipment are small tools such as wind (electric) brush, anti rust treatment gun, grinding and polishing sand wheel and wind (electric) shovel. Relying on the high-frequency impact and friction effect of mechanical equipment force, anti rust treatment and elimination of air oxide scale, old paint and other wastes.

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、钢丸抛射到铁艺制品的表面，冲击和磨擦掉氧化皮、锈痕、旧漆、型砂等。

Spray treatment is to use mechanical centrifugation, compressed air and high-pressure water flow as power to shoot abrasive, sand and steel shot onto the surface of iron products, impact and rub off oxide scale, rust mark, old paint, molding sand, etc.

有机化学解决是运用独特的酸碱性水溶液来浸、溶铁艺配件工艺品，根据放热反应来除净空气氧化皮、锈痕、油渍，即说白了的“酸洗钝化”。

Organic chemical solution is to use a unique acid-base aqueous solution to soak and dissolve iron accessories and handicrafts, and remove air oxide scale, rust marks and oil stains according to exothermic reaction, which is called "acid pickling and passivation".

2、除油对于铁艺大门制品来讲，一般可采用有机溶液，碱液，电化学等方法，目前市面所售的各种金属清洗剂也较适用。

2. For iron gate products, oil removal can generally adopt organic solution, alkali solution, electrochemistry and other methods. At present, various metal cleaning agents sold on the market are also more applicable.
