                  CQ不銹鋼磁力泵為什么會生銹?

                     CQ不銹鋼磁力泵為什么會生銹?
                    許多客戶買了CQ不銹鋼磁力泵,回去用了一段時間感覺磁力泵生銹了,就認為是產品運用了假的不銹鋼原料。其實不然,不銹鋼磁力泵正是靠其外表構成的一層極薄而鞏固細密的安穩的富鉻氧化膜(防護膜),避免氧原子的持續進入、持續氧化,而取得抗銹蝕的才能。
                    一旦有某種原因,這種薄膜遭到了不斷地損壞,空氣或液體中氧原子就會不斷進入或金屬中鐵原子不斷地析離出來,構成疏松的氧化鐵,金屬外表也就遭到不斷地銹蝕。
                    這種外表膜遭到損壞的方式許多,日常日子中多見的有如下幾種:不銹鋼磁力泵外表存積著含有其他金屬元素的粉塵或異類金屬顆粒的附著物,CQ不銹鋼磁力泵在濕潤的空氣中,附著物與不銹鋼間的冷凝水,將二者連成一個微電池,引發了電化學反響,保護膜遭到損壞,稱之謂電化學腐蝕。
                    不銹鋼磁力泵外表粘附有機物汁液(如瓜菜、面湯、痰等),在有水氧狀況下,構成有機酸,長期則有機酸對金屬外表的腐蝕。不銹鋼磁力泵外表粘附含有酸、堿、鹽類物質(如裝修墻面的堿水、石灰水噴濺),引起部分腐蝕。
                    CQ不銹鋼磁力泵在有污染的空氣中(如含有很多硫化物、氧化碳、氧化氮的大氣),遇冷凝水,構成硫酸、硝酸、醋酸液點,引起化學腐蝕。
