            如關(guān)于濟(jì)南護(hù)欄外表上油污多而腐蝕少的冷軋鋼板，外表處置的重點(diǎn)是去掉油脂。可進(jìn)行脫脂清洗而不進(jìn)行除銹處置。假如濟(jì)南護(hù)欄上的油污主要是可發(fā)作皂化反響的油脂，就應(yīng)該挑選以強(qiáng)堿為主要成分的清洗劑，促使它發(fā)作皂化反響而被去掉；假如油污的主要成分是不能發(fā)作皂化反響的礦物油，就應(yīng)挑選具有潮濕渙散乳化才能的外表活性劑作為清洗劑，使它被乳化、渙散而脫離噴涂護(hù)欄外表。

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.

假如濟(jì)南護(hù)欄 http://www.sdwoerde.com/ 將來是要在惡劣的自然環(huán)境中運(yùn)用的，由于常常要飽嘗溫度劇烈改變、激烈日光照耀、雨雪風(fēng)沙襲擊等自然條件的影響，對涂膜的耐蝕性需求很高，就應(yīng)選用清洗、磷化、鈍化等多步技術(shù)處置，進(jìn)步濟(jì)南護(hù)欄的維護(hù)功能，以進(jìn)步涂層的耐蝕性；而對在室內(nèi)運(yùn)用的濟(jì)南護(hù)欄，前處置的需求通常就較低，選用的技術(shù)也較簡略。

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.
