        無縫盤管不會輕易的生銹,因為在它不銹鋼的表面上有一層鈍化膜,這層鈍化膜的作用就是保護不銹鋼免受外界的侵蝕而生銹.但也不是說都可以受到鈍化膜的保護,不銹鋼就不會生銹了,但是天然界都有一種定律,無論你多強,總有一些東西比你強.固然鈍化膜能夠防止盤管被氧化,但是跟著時間的推移,這層鈍化膜的作用將會越來越小,最后完全被氧化,這樣不銹鋼裸露在空氣中,就會生銹,由于不銹鋼中也是含有鐵成分的.所以不銹鋼表面污物引起的銹,可硝酸或研磨洗滌劑洗滌,也可用專門的洗滌藥品洗滌.只要我們使用準確的保養方法,就能延長不銹鋼的使用壽命,保持其潔凈、明亮、華麗的氣派.
        Seamless coil will not rust easily, because it has a passive film on the surface of stainless steel. The role of this passive film is to protect stainless steel from external corrosion and rust. But it does not mean that all can be protected by passive film, stainless steel will not rust, but there is a law in nature, no matter how strong you are, there is always one. Some things are better than you. Although passivation film can prevent coil from being oxidized, with the passage of time, the role of this passivation film will become less and less, and eventually be completely oxidized, so that stainless steel exposed in the air, will rust, because stainless steel also contains iron. So stainless steel surface dirt caused by rust, nitric acid or Grinding detergent can also be washed with special detergents. As long as we use accurate maintenance methods, we can extend the service life of stainless steel and maintain its clean, bright and gorgeous style. 文章來源:http://www.wwwb5383.com/
