如关于济南护栏外表上油污多而腐蚀少的冷轧钢板,外表处置的重点是去掉油脂。可进行脱脂清洗而不进行除锈处置。假如济南护栏上的油污主要是可发作皂化反响的油脂,就应该挑选以强碱为主要成分的清洗剂,促使它发作皂化反响而被去掉;假如油污的主要成分是不能发作皂化反响的矿物油,就应挑选具有潮湿涣散乳化才能的外表活性剂作为清洗剂,使它被乳化、涣散而脱离喷涂护栏外表。
such as on the surface of the fence in ji'nan and less corrosion and corrosion of cold-rolled steel plate, the surface treatment is to remove the oil. can the degreasing cleaning without rust disposal. if jinan guardrail oil is mainly can happen saponification reaction of oil, it should be selected with the alkali as the main component of cleaning agent, causing it to attack saponification reaction is then removed; if the oil is the main component of cannot occur saponification reaction of mineral oil, it should be selected with wet lax emulsification ability of surface active agent as a cleaning agent, causing it to be emulsified and lax from spray guardrail appearance.
假如 http://www.sdwoerde.com/ 将来是要在恶劣的自然环境中运用的,由于常常要饱尝温度剧烈改变、激烈日光照耀、雨雪风沙袭击等自然条件的影响,对涂膜的耐蚀性需求很高,就应选用清洗、磷化、钝化等多步技术处置,进步济南护栏的维护功能,以进步涂层的耐蚀性;而对在室内运用的济南护栏,前处置的需求通常就较低,选用的技术也较简略。
if jinan guardrail in the future is to use in the harsh natural environment, because often suffered the effects of the drastic change of the temperature, intense sunlight shine, rain and snow sand attacks and other natural conditions, on the coating corrosion resistance of high demand, it should be selection of cleaning, phosphating and passivation multi-step disposal technology, progress of jinan guardrail maintenance function to the progress of coating corrosion resistance; and in the interior with the jinan guardrail, before disposal needs usually on the lower, the selection of the technology is simple.
