                    剖析鑄鐵護欄的表面預處理事項

                    來源:http://www.penidatrip.com添加時間:2021-08-20 14:48:53

                    為保障裝飾涂層(鍍層)與鑄鐵護欄表面有良好的附著力,在涂裝(鍍層)前,須盡可能清潔鐵護欄表面上的焊渣、氧化皮、銹跡、油脂、污垢和水,否則容易引起起泡、開裂、裂紋等,涂層(鍍層)剝落等現象。所謂預處理,是指用機械或化學、電化學等工藝方法,在鍍(鍍)鐵產品前消去其表面缺陷。

                    In order to ensure good adhesion between the decorative coating (coating) and the surface of cast iron guardrail, the welding slag, oxide skin, rust, grease, dirt and water on the surface of iron guardrail must be cleaned as much as possible before coating (coating), otherwise it is easy to cause blistering, cracking, cracking, coating (coating) peeling, etc. The so-called pretreatment refers to eliminating the surface defects of iron products before plating (plating) by mechanical or chemical, electrochemical and other process methods.

                    一、除銹、氧化皮和焊渣的方法,鑄鐵護欄廠家通常應用的主要方法有:手工處理、機械處理、噴涂處理、電化學處理、化學處理(酸洗)以及火焰處理。

                    1、 Methods for rust removal, scale removal and welding slag. The main methods commonly used by cast iron guardrail manufacturers are: manual treatment, mechanical treatment, spraying treatment, electrochemical treatment, chemical treatment (pickling) and flame treatment.

                    人工處理主用砂布、刮刀、錘鑿、廢砂輪、鋼絲刷等工具,通過人工打磨、鑿除、刷除除銹、氧化皮、焊渣、灰塵等表面污垢。

                    The main tools for manual treatment are abrasive cloth, scraper, hammer chisel, waste grinding wheel, steel wire brush and other tools, and the surface dirt such as rust, scale, welding slag and dust are removed by manual grinding, chiseling and brushing.

                    機械處理常用的工具有風(電)刷、除銹槍、拋光砂輪、風(電)鏟等工具,借助于機械力的高頻沖擊和摩擦,能清理掉氧化皮、舊漆等銹垢。

                    Common tools for mechanical treatment include wind (electric) brush, derusting gun, polishing grinding wheel, wind (electric) shovel and other tools. With the help of high-frequency impact and friction of mechanical force, rust scale such as oxide skin and old paint can be removed.

                    噴涂處理是以機械離心、壓縮空氣和高壓水流為動力,把磨料、砂粒和鋼丸噴射到熟鐵表面,以沖擊和擦掉氧化皮、銹痕、舊漆、型砂等。

                    The spraying treatment is driven by mechanical centrifugation, compressed air and high-pressure water flow to spray abrasive, sand and steel shot onto the surface of wrought iron to impact and wipe off oxide scale, rust mark, old paint, molding sand, etc.

                    化學處理是用特定配料的酸溶液浸泡、溶解鑄鐵護欄,經過化學反應清理掉氧化皮、銹痕和油污,即所述的“酸洗”。

                    Chemical treatment is to soak and dissolve the cast iron guardrail with the acid solution of specific ingredients, and clean up the oxide scale, rust mark and oil stain through chemical reaction, that is, the "pickling".

                    二、鑄鐵護欄可應用有機溶液、堿溶液、電化學等方法。目前市場上銷售的各金屬清洗劑也比較適合。

                    2、 Cast iron guardrail can be used by organic solution, alkali solution, electrochemistry and other methods. At present, the metal cleaning agents sold on the market are also more suitable.

                    關于鑄鐵護欄的處理工藝還有許多,如想了解其他工藝產品,歡迎咨詢鑄鐵護欄廠家喲,期待您的來電。

                    There are many processing technologies for cast iron guardrail. If you want to know about other process products, please consult the cast iron guardrail manufacturer. We look forward to your call.
