為什么碳鋼彎頭不能接觸水?你知道為什么碳鋼彎頭不能接觸水嗎?接下來(lái)小編就為我們簡(jiǎn)略介紹一下。二氧化碳是水中存在較多的雜質(zhì)，通常情況下是以游離情況存在。水中存在的很多碳酸氫根在pH低時(shí)，也是以二氧化碳游離情況存在的，所以產(chǎn)生了碳酸平衡問(wèn)題。此現(xiàn)象反應(yīng)式如下： </p> <p> CO2+H2O=H++HCO3-=2H++CO32- </p> <p> 因而，水中二氧化碳越多，生成H+越多，水的pH值越低，產(chǎn)生酸性的腐蝕性水，碳鋼彎頭推薦，破壞了碳鋼外表生成的維護(hù)膜引起碳鋼腐蝕。其腐蝕的化學(xué)反應(yīng)如下： </p> <p> 2CO2+Fe(OH)2=Fe(HCO3)2 </p> <p> 4Fe(HCO3)2+O2+2H2O=4Fe(OH)3+8CO2 假如除鹽水中進(jìn)入二氧化碳，水的電導(dǎo)率即會(huì)上升，腐蝕性增大。因而除鹽水箱應(yīng)當(dāng)有避免大氣中二氧化碳溶入水箱的方法，如用N2或其他惰性氣體在水箱頂部空間進(jìn)行維護(hù)，碳鋼彎頭推薦，可以避免二氧化碳污染純水水質(zhì)。二氧化碳是空氣中常見(jiàn)的化合物，碳與氧反應(yīng)生成其化學(xué)式為CO2，一個(gè)二氧化碳分子由兩個(gè)氧原子與一個(gè)碳原子通過(guò)共價(jià)鍵構(gòu)成，碳鋼彎頭推薦，常溫下是一種無(wú)色無(wú)味氣體，密度比空氣大，能溶于水，與水反應(yīng)生成碳酸，不支持燃燒。固態(tài)二氧化碳?jí)嚎s后俗稱為干冰。二氧化碳不被認(rèn)為是加重溫室效應(yīng)的主要來(lái)歷。
