style="text-indent:25px">一般來(lái)說(shuō)，304不銹鋼方管知識(shí)易離子化的金屬容易氧化，即容易腐蝕，而事實(shí)上并非完全如此，有些金屬如鋁、鎂、鉻等雖然易離子化，但由于它們?cè)诖髿饣蛩腥菀咨梢粚痈g產(chǎn)物的薄膜，從而卻提高了耐蝕性。通過(guò)化學(xué)或電化學(xué)方法使鋁及鋁合金屬表面狀態(tài)發(fā)生變化，使其溶解速度急劇下降，使耐蝕性提高，此種工藝過(guò)程稱為鋁材鈍化處理。鈍化往往伴隨陽(yáng)極電位突然升高，從而使陽(yáng)極反應(yīng)難以進(jìn)行，使金屬腐蝕速度減慢或停止。鈍化其實(shí)是通過(guò)鈍化液的化學(xué)反應(yīng)，把活潑的金屬表層變成惰性的表層，從而阻止外界有破壞性的物質(zhì)與金屬表面產(chǎn)生反應(yīng)，從而達(dá)到延長(zhǎng)生銹時(shí)間的目的。不銹鋼方管需要經(jīng)常擦拭，除去灰塵，保持清潔干燥。</p><div
