推 aa182201 : 鋁不會生鏽總是常識吧 11/19 22:44
哪個老師教你鋁不會生鏽的？

→ aa182201 : 生鏽 11/20 09:06
→ aa182201 : 這個國中的化學就該教了 11/20 09:06
噓 aa182201 : 而且生鏽的原因是氧化 氧化的不一定是生鏽 版主連這 11/20 09:21

→ aa182201 : 本知識都不懂? 11/20 09:24
鋁一旦生鏽，會在外層形成一層保護層，我們稱之為氧化鋁。
這層保護雖然薄薄一層，卻能有效阻隔空氣和許多種化學物質。
BUT，越純淨的鋁越容易產生氧化現象，反之則否。
另外水銀可以瓦解這層保護層，並徹底的破壞鋁，讓鋁無法再生這層保護。
推 aa182201 : 呵 就算你說你考一百我也是看看而已 連常識都不知道 11/20 10:27
→ aa182201 : ?考在高有甚麼用 11/20 10:27
→ aa182201 : 更別說連馬路單車可以騎都不知道嗎?單車的錯笑死我 11/20 10:28
→ aa182201 : 了 現在版主什麼都不用會 連說錯話都不用來更正? 11/20 10:28
→ aa182201 : 隨便一個版的版主對他版上的基本知識都比你高了 11/20 10:29
→ aa182201 : 我最起碼知道馬路右側可以給單車騎 而你身為單車版 11/20 10:30
→ aa182201 : 版主卻說有單車道單車錯? 11/20 10:30
→ aa182201 : 這會不會太搞笑 11/20 10:32
→ aa182201 : 不管是不是快車道最右側單車都可以行駛你不知道?那 11/20 10:33
→ aa182201 : 請問沒單車道的他是用牽的嗎? 11/20 10:33
推 aa182201 : 原來說錯話不用更正直接說不知道?有查過還不知道? 11/20 10:36
→ aa182201 : 現在的版主道理說不過人就開始 ...了? 11/20 10:38
推 aa182201 : 你可以繼續堅持沒關係 11/20 10:43
原則上要從鋁這件事跳到板主怎樣怎樣的，我比較認為是你講不贏在轉移話題。
另外，PTT的板主並沒有規定一定要是該板塊的專業人士。
有專業卻不會管理，跟不專業卻有管理能力，我可以跟你說，適任的一定是後者。
當然兩者都具備是更好，不過不強求。
