　　不(bu)(bu)銹鋼(gang)卷閘(zha)門顧名(ming)思義就是(shi)不(bu)(bu)容易(yi)生(sheng)銹的(de)鋼(gang)材所(suo)制，這里的(de)"不(bu)(bu)銹"是(shi)相(xiang)對的(de)，不(bu)(bu)是(shi)的(de)是(shi)相(xiang)對于碳鋼(gang)而言(yan)。不(bu)(bu)銹鋼(gang)不(bu)(bu)容易(yi)生(sheng)銹，但不(bu)(bu)是(shi)不(bu)(bu)生(sheng)銹，只(zhi)是(shi)在相(xiang)同條件和環境中，較(jiao)碳鋼(gang)而言(yan)不(bu)(bu)容易(yi)被腐蝕和生(sheng)銹。

　　Stainless steel roller shutter, as the name suggests, is made of steel that is not easily rusted. Here, "stainless" is relative, not absolute, relative to carbon steel. Stainless steel is not easy to rust, but it is not absolutely rust free. It is just that under the same conditions and environment, it is less likely to corrode and rust compared to carbon steel.

　　生(sheng)銹"其實(shi)質是腐蝕(shi)或(huo)(huo)稱(cheng)之為(wei)銹蝕(shi)，是由于鋼鐵(tie)表(biao)面與大氣中(zhong)的(de)氧(yang)、水(shui)分及其酸、堿、鹽等物質發生(sheng)化學(xue)作用(yong)或(huo)(huo)電化學(xue)作用(yong)而(er)引起的(de)變色或(huo)(huo)腐蝕(shi)稱(cheng)為(wei)銹蝕(shi)。表(biao)面產(chan)生(sheng)的(de)物質是"銹"是鐵(tie)的(de)氧(yang)化物，也叫做物質氧(yang)化的(de)過程。

　　Rust "is essentially corrosion, also known as rusting, caused by chemical or electrochemical reactions between the surface of steel and oxygen, moisture, acids, bases, salts, and other substances in the atmosphere, resulting in discoloration or corrosion. The substance produced on the surface is" rust ", which is an oxide of iron, also known as the process of material oxidation.

　　不銹(xiu)(xiu)鋼(gang)卷(juan)閘(zha)門為什(shen)么不易(yi)生銹(xiu)(xiu)，這就和鉻有(you)著直接(jie)的(de)(de)關系了，在基體內加入12.5%以上的(de)(de)鉻。在氧(yang)化(hua)(hua)性(xing)(xing)腐敗無能(neng)蝕介質中，鉻能(neng)使鋼(gang)表面很快地(di)生成一層致密的(de)(de)鈍(dun)化(hua)(hua)膜，防止金(jin)屬基體被破壞。當含(han)鉻量(liang)在12.5%以上時(shi)，就會形成一層致密的(de)(de)穩定的(de)(de)鈍(dun)化(hua)(hua)膜，防銹(xiu)(xiu)性(xing)(xing)能(neng)發生躍進式的(de)(de)實變，耐銹(xiu)(xiu)蝕能(neng)力大大增強(qiang)，這就是為什(shen)么不銹(xiu)(xiu)鋼(gang)中的(de)(de)含(han)鉻量(liang)要有(you)12%以上的(de)(de)原因。

　　The reason why stainless steel roller shutter is not easy to rust is directly related to chromium, which is added to the substrate with more than 12.5% chromium. In oxidizing and non corrosive media, chromium can quickly form a dense passivation film on the surface of steel, preventing the metal substrate from being damaged. When the chromium content is above 12.5%, a dense and stable passivation film will be formed, and the rust prevention performance will undergo a leap forward transformation, greatly enhancing the corrosion resistance. This is why the chromium content in stainless steel should be above 12%.

　　還(huan)有(you)一種(zhong)方法，就是在不銹(xiu)鋼卷閘(zha)門加入鉻的(de)同時，再加放(fang)適量的(de)Ni、Mo、V等(deng)合金元(yuan)素(su)后，防銹(xiu)性能(neng)更強。

　　Another method is to add chromium to the stainless steel rolling shutter, and then add an appropriate amount of alloy elements such as Ni, Mo, V, etc. to enhance its rust prevention performance.

　　其次是不(bu)銹(xiu)鋼卷閘門(men)的(de)(de)耐蝕性(xing)級(ji)還與碳量、含(han)鉻量，表面(mian)處理狀(zhuang)態有(you)關。不(bu)銹(xiu)鋼卷閘門(men)隨(sui)著含(han)碳量的(de)(de)提高，防(fang)銹(xiu)性(xing)能(neng)下降(jiang)，3Cr13的(de)(de)防(fang)銹(xiu)性(xing)能(neng)不(bu)及2Cr13。隨(sui)著鋼中含(han)量的(de)(de)提高，防(fang)銹(xiu)性(xing)能(neng)上升。表面(mian)處理方(fang)法和狀(zhuang)態同時影(ying)響(xiang)防(fang)銹(xiu)能(neng)力。卷閘門(men)表面(mian)鍍鉻，電(dian)解拋光、鏡(jing)面(mian)拋光、砂帶、手工拋光的(de)(de)防(fang)銹(xiu)性(xing)能(neng)依次遞減。

　　Secondly, the corrosion resistance level of stainless steel rolling gates is also related to the carbon content, chromium content, and surface treatment status. With the increase of carbon content, the rust prevention performance of stainless steel rolling gates decreases, and the rust prevention performance of 3Cr13 is inferior to that of 2Cr13. With the increase of steel content, the anti rust performance improves. The surface treatment method and state simultaneously affect the rust prevention ability. The rust prevention performance of the roller shutter surface is gradually reduced by chrome plating, electrolytic polishing, mirror polishing, sand belt polishing, and manual polishing.
