铝卷在使用的过程中,因为一些外界因素,可能会出现腐蚀问题的,影响它的寿命,我们需要做好一些保护工作,避免腐蚀问题的发生,接下来就来说一下铝卷怕什么腐蚀,怎样有效避免铝卷受到腐蚀。


During the use of aluminum coil, due to some external factors, corrosion problems may occur and affect its service life. We need to do some protection work to avoid corrosion problems. Next, let's talk about what corrosion aluminum coil is afraid of and how to effectively avoid corrosion of aluminum coil.


先说一下铝卷氧化腐蚀的原因:


First of all, let's talk about the causes of oxidation corrosion of aluminum coil:


正常情况的氧化是指铝卷在使用后,例如包在管道上以后,铝卷表面会完全和空气接触,形成一层氧化膜,这层氧化膜会保护铝卷不再进一步腐蚀,所以使用后,即使再淋雨,户外暴晒,铝卷也不会腐蚀。腐蚀性氧化是指铝卷在未使用前,因为成卷装包装状态,铝卷表面未完全和空气接触,还未形成保护层,这种情况下,铝卷若进水,被淋雨或受潮后,湿气中的水份会和铝卷表面进行化学反应,造成铝卷的腐蚀,腐蚀后的铝卷会出现腐蚀痕迹,厉害的情况会发黑发乌,就像被火烧过一样。但这种腐蚀发生后,不会再出现铝卷的二次伤害,铝卷本身是没有问题的,只是外观受损。


Normal oxidation refers to that after the aluminum coil is used, for example, wrapped on the pipe, the surface of the aluminum coil will completely contact with the air and form an oxide film, which will protect the aluminum coil from further corrosion, so the aluminum coil will not corrode even if it is exposed to rain and outdoor sun after use. Corrosive oxidation refers to the fact that the surface of the aluminum coil is not completely in contact with the air and has not formed a protective layer because of the package state of the aluminum coil before use. In this case, if the aluminum coil is exposed to water, rain or moisture, the moisture in the moisture will react with the surface of the aluminum coil, causing corrosion of the aluminum coil. After corrosion, the aluminum coil will have corrosion traces, and in severe cases, it will become black and black, just like being burned. However, after this corrosion occurs, there will be no secondary damage to the aluminum coil. The aluminum coil itself is no problem, but the appearance is damaged.


铝卷加工厂家介绍几种容易造成铝卷腐蚀的原因和避免铝卷氧化腐蚀的方法:


The aluminum coil processing manufacturer introduces several reasons that are easy to cause aluminum coil corrosion and methods to avoid aluminum coil oxidation corrosion:


(1)车间、仓库房顶有漏雨、雪的地方,不应放置铝卷。


(1) Aluminum rolls shall not be placed on the roof of workshops and warehouses where there is rain and snow leakage.
