Vim li cas Aluminium Dim Dub Dub Tshaj Plaws Hauv Kev Lag Luam Niaj Hnub
Aluminium tau ua rau nws txoj haujlwm ua cov khoom siv hauv pob zeb hauv kev tsim khoom niaj hnub, ua tsaug rau kev sib xyaw ua ke ntawm cov khoom. Nrog lub ntom ntom ntawm tsuas 2.7 g / cmÃ, nws yog qhov tseem ceeb dua ntais dua li cov hlau (7.85 g / cm³ Nws cov kev sib txawv siab tso cai rau nws yuav tsum tau ua rau hauv cov ntawv sib txawv thiab cov hluav taws xob ua rau muaj cov cua sov thiab cov khoom siv hluav taws xob. Tsis tas li ntawd, Aluminium lub ntuj tsis kam rau corrosion, muab tau los ntawm ib qho nyias, tus kheej- kev rov hais dua ntawm kev ua lag luam.
Txawm li cas los xij, lub neej ntawd nyiaj - cov tsos pom ntawm txhuas feem ntau tsis ua tiav kev ua haujlwm thiab kev ua kom zoo nkauj ntawm cov ntawv thov tshwj xeeb.

Kev sib xyaw ntawm Tshuaj Txhuas Txhuas Blackening Tus Neeg Sawv Cev: Cov Khoom Tseem Ceeb thiab Ua Haujlwm
Lub siab -} Kev Ua Haujlwm TshuajAluminium Blackening Tus Neeg Sawv Cevyog ib qho sib xyaw ua ke muaj tseeb ntawm plaub qhov sib xyaw ua ke, txhua tus ua lub luag haujlwm tseem ceeb hauv kev ua yeeb yaj kiab, Durable dub zaj duab xis:
Tus oxidants: Thawj cov tsav tsheb ntawm cov tshuaj tiv thaiv dub, oxidants muab oxygen kom hloov aluminium rau txhuas oxide (al₂o₃), lub hauv paus ntawm zaj duab xis dub. Common oxidants include potassium permanganate (KMnO₄), sodium dichromate (Na₂Cr₂O₇), and hydrogen peroxide (H₂O₂). Potassium permanganate, muaj txiaj ntsig hauv acidic / neured kev daws teeb meem, reacts nrog txhuas los ua cov duab tsaus nti uas txhim kho zaj duab xis xim dub. Sodium Dichromate, siv hauv kev daws teeb meem alkaline, tsim chromium (III) oxide (cr₂o₃), uas ntxiv ntom thiab corrosion tsis kam. Hydrogen Peroxide, ib qho eco - Tus phooj ywg xaiv dej, decomposes rau hauv dej thiab oxygen tab sis ntsuas kub kom tsis txhob muaj qhov pib kub.
Cov neeg sawv cev sib luag: Cov no tiv thaiv kev tsim ntawm dawb, gelatinous aluminium hydroxide (al (Oh) ₃), uas yuav thaiv covAluminium Blackening Tus Neeg Sawv CevLos ntawm reacting nrog txhuas matrix. Los ntawm kev tsim ruaj khov, dej {{- soluble complex nrog aluminium ions (al³⁺), complexingtus sawv cevXyuas kom muaj kev sib txawv thoob plaws ntawm qhov chaw. Citric acid (c₆h₈o₇), tartaric acid (carta acid (c₄h₆o₆), thiab Edta (c₁₀h₁₆n₂o₈) yog cov kev xaiv ntau yam. Edta, piv txwv li, ua cov ntawv 1: 1 nyuaj nrog Al³n (cav Kf {}}}}} ions yaj txawm tias ntawm qhov siab.
