Now Jinan roller shutter door has been basically popularized, but people don't pay much attention to the maintenance of roller shutter door, which is a very bad phenomenon. Summer and autumn is the rainy season in Jinan. Special attention should be paid to rust prevention during the use of rolling shutter doors. The rusty Jinan rolling shutter doors not only look ugly, but also greatly reduce the efficiency when they are convenient to use.

金屬卷簾門在日常的使用過程中，暴露在空氣中，難免會風吹日曬，所以氧化的概率是很高的。

In the daily use of metal roller shutter doors, exposure to the air will inevitably lead to wind and sun, so the probability of oxidation is very high.

以前安裝的舊式金屬卷簾門，因為材質的關系，使用2-3年后，很容易出現(xiàn)門體氧化，銹蝕表面甚破壞門體結構，從而造成金屬卷面門不能使用的情況。

Because of the material, the old metal rolling shutter door installed before is easy to oxidize, rust the surface and even damage the door structure after 2-3 years of use, resulting in the non use of the metal rolling shutter door.

現(xiàn)在這個問題已經引起了卷簾門廠家的足夠重視，新出產的金屬卷簾門在出廠之前，在表面都做過特殊處理，可以保證在正常使用的情況下3-5年都不會銹蝕。

Now this problem has attracted enough attention from the rolling shutter door manufacturers. The newly produced metal rolling shutter door has been specially treated on the surface before leaving the factory, which can ensure that it will not rust for 3-5 years under normal use.

所以，舊式的金屬卷簾門，一旦發(fā)生氧化，就預示著門體離報廢不遠了。這時候可以在表面噴上一層油漆，延緩金屬的氧化。

Therefore, once the old metal rolling shutter door is oxidized, it indicates that the door body is not far from scrapping. At this time, a layer of paint can be sprayed on the surface to delay the oxidation of metal.

不管是舊式的還是新式的金屬卷簾門，都需要每個禮拜擦拭吸附在上面的灰塵、雨水等異物，防止金屬的氧化。

Whether old or new metal roller shutter doors, they need to wipe the dust, rain and other foreign matters adsorbed on them every week to prevent metal oxidation.

另外，日常在使用過程中，要避免碰撞門體，這樣會造成濟南卷簾門的金屬材料裸露在空氣中，縮短了使用壽命。

In addition, in the process of daily use, it is necessary to avoid collision with the door body, which will cause the metal materials of Jinan roller shutter door to be exposed in the air and shorten the service life.

為了防止卷簾門生銹，我們可以定期用棉布蘸上少量的防銹油或縫紉機油擦拭卷簾門表層部分。若發(fā)現(xiàn)卷簾門已經開始有銹斑，那我們應該盡早用棉紗蘸機油涂于銹處，這樣可以除掉銹跡，而不能直接用砂紙和其它糙面材料進行打磨。

In order to prevent the rolling shutter door from rusting, we can regularly wipe the surface part of the rolling shutter door with cotton cloth dipped in a small amount of antirust oil or sewing oil. If it is found that the rolling shutter door has begun to have rust spots, we should apply cotton yarn dipped in engine oil to the rust as soon as possible, so as to remove the rust, rather than grinding it directly with sandpaper and other rough materials.
