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.

為了確保抗銹及裝飾設計實際效果超過盡量長期的目地，必然性地要采用很多相對的表層工藝處理和中后期對施工技術及原材料挑選。

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、鐵藝大門配件制品表面的處理

1、 Surface treatment of iron gate accessories

為了確保裝飾設計噴漆層與鐵藝配件工藝品表層有優良的結合性，務必在噴漆執行以前，對鐵藝大門配件工藝品表層的空氣氧化皮、焊穿、銹痕、植物油脂、臟污、水分開展盡量的，不然易導致噴漆層出泡、裂開、起層及脫落等狀況。所謂處理是指使用機械或化學、電化學等技術方法在噴涂前熟鐵產品的表面缺陷。

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、除鐵銹、空氣氧化皮焊渣的關鍵方式 有手工制作解決、機械設備解決、噴涌解決、有機化學解決（酸洗鈍化）、光電催化解決和火焰處理等方式 。 手工處理主要使用砂布，刮刀，錘鑿、鋼絲刷、廢砂輪等工具，靠手工打磨敲鏟、掃刷來除去銹垢、氧化皮及焊渣，塵土等表面污物。

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.

機械設備解決更常見的有風（電）動刷，防銹處理槍，打磨拋光沙輪片及風（電）鏟等小工具，依靠機械設備力的高頻率沖擊性與摩擦的功效防銹處理和空氣氧化皮舊漆等廢棄物。

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.

噴射處理是利用機械離心、壓縮空氣、高壓水流等為動力，將磨料、砂石、鋼丸拋射到鐵藝制品的表面，沖擊和磨擦掉氧化皮、銹痕、舊漆、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.

有機化學解決是運用獨特的酸堿性水溶液來浸、溶鐵藝配件工藝品，根據放熱反應來除凈空氣氧化皮、銹痕、油漬，即說白了的“酸洗鈍化”。

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、除油對于鐵藝大門制品來講，一般可采用有機溶液，堿液，電化學等方法，目前市面所售的各種金屬清洗劑也較適用。

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.
