Aluminium yog ntau yam thiab dav siv hlau nyob rau hauv ntau yam lag luam vim nws lub teeb yuag, durability, thiab tsis kam mus corrosion. Txawm li cas los xij, txawm hais tias nws lub koob npe nrov yog corrosion-resistant, aluminium tseem tuaj yeem raug cuam tshuam los ntawm corrosion dhau sijhawm. Nkag siab txog cov txheej txheem corrosion ntawm aluminium yog qhov tseem ceeb rau kev tswj nws txoj kev ncaj ncees thiab ua kom nws lub neej ntev. Nyob rau hauv tsab xov xwm no, peb yuav rhuav tshem cov txheej txheem corrosion ntawm txhuas, tshawb xyuas cov khoom uas ua rau nws cov corrosion, thiab muab cov lus qhia txog kev tiv thaiv thiab txo cov corrosion.
Corrosion yog txheej txheem ntuj tsim uas tshwm sim thaum cov hlau ua rau lawv ib puag ncig, ua rau cov hlau tsis zoo. Aluminium yog cov hlau reactive, tab sis nws tsim ib txheej oxide nyias ntawm nws qhov chaw thaum raug huab cua, uas ua raws li kev tiv thaiv kev tiv thaiv ntxiv corrosion. Qhov no oxide txheej yog dab tsi muab aluminium nws corrosion kuj. Txawm li cas los xij, txheej txheej oxide no tuaj yeem raug cuam tshuam hauv qee yam kev mob, ua rau corrosion.
Muaj ntau hom kev xeb uas tuaj yeem cuam tshuam rau txhuas, suav nrog galvanic corrosion, pitting corrosion, thiab crevice corrosion. Galvanic corrosion tshwm sim thaum txhuas los rau hauv kev sib cuag nrog cov hlau zoo dua qub, xws li stainless hlau, nyob rau hauv lub xub ntiag ntawm electrolyte (xws li dej ntsev). Qhov sib txawv ntawm cov hluav taws xob muaj peev xwm ntawm ob lub hlau ua rau cov txhuas corrode sai dua. Pitting corrosion yog localized corrosion uas tsim cov pits me me los yog qhov nyob rau saum npoo ntawm txhuas, thaum crevice corrosion tshwm sim nyob rau hauv qhov chaw uas muaj oxygen tsawg, xws li ntawm overlapping hlau nto.
Cov yam ntxwv uas ua rau muaj kev txhim kho corrosion ntawm txhuas muaj xws li raug ya raws, dej ntsev, acidic lossis alkaline ib puag ncig, kub siab, thiab kev puas tsuaj rau txhua yam. Kev cuam tshuam rau cov xwm txheej no tuaj yeem ua rau tsis muaj zog tiv thaiv oxide txheej ntawm qhov chaw ntawm txhuas, ua rau nws muaj kev cuam tshuam rau corrosion. Tsis tas li ntawd, kev tsim khoom tsis raug, kev cia khoom tsis raug thiab tuav, thiab kev npaj tsis txaus tuaj yeem ua rau muaj kev cuam tshuam ntawm txhuas.
Txhawm rau tiv thaiv thiab txo qhov corrosion ntawm aluminium, ob peb lub tswv yim tuaj yeem ua haujlwm. Ib txoj hauv kev zoo tshaj plaws los tiv thaiv txhuas los ntawm corrosion yog siv cov txheej tiv thaiv, xws li anodized lossis pleev xim rau. Anodizing yog ib txoj kev uas yuav immersing cov txhuas nyob rau hauv ib tug electrolyte tov thiab dhau ib tug hluav taws xob tam sim no los ntawm nws los tsim ib tug tuab, ruaj oxide txheej ntawm qhov chaw. Cov txheej txheej oxide no txhim kho qhov kev tiv thaiv corrosion ntawm txhuas thiab tuaj yeem txhim kho nws cov tsos.
Kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas ntawm txhuas qhov chaw kuj tseem ceeb rau kev kuaj xyuas thiab hais txog cov cim ntawm corrosion thaum ntxov. Ntxuav cov txhuas tsis tu ncua nrog xab npum me me thiab dej, thiab tsis txhob siv cov tshuaj ntxuav lossis cov cuab yeej siv, tuaj yeem pab khaws cov txheej txheem oxide tiv thaiv thiab tiv thaiv corrosion. Nws tseem yog ib qho tseem ceeb kom tsis txhob nthuav tawm cov txhuas rau qhov chaw hnyav lossis cov tshuaj lom neeg uas tuaj yeem ua kom corrosion, thiab khaws cov khoom txhuas nyob rau hauv qhov chaw qhuav, zoo-ventilated.
Ntxiv nrog rau kev tiv thaiv kev tiv thaiv, kuj tseem muaj txoj hauv kev los kho thiab rov ua kom corroded aluminium nto. Lub teeb nto corrosion tuaj yeem raug tshem tawm los ntawm kev siv cov abrasive me me, xws li cov ntawv xuab zeb zoo los yog cov ntaub nplaum nplaum, tom qab ntawd ntxuav lub ntsej muag nrog kev daws ntawm vinegar thiab dej. Rau kev txhim kho corrosion hnyav dua, cov kev pabcuam kev kho dua tshiab yuav tsum tau ua kom huv thiab kho cov txhuas kom zoo.
Zuag qhia tag nrho, nkag siab txog cov txheej txheem corrosion ntawm txhuas thiab ua cov kauj ruam tiv thaiv thiab txo cov corrosion tuaj yeem pab ua kom lub neej ntev ntawm cov khoom txhuas thiab cov qauv. Los ntawm kev ua raws li kev saib xyuas kom raug, siv cov txheej txheem tiv thaiv, thiab daws teeb meem corrosion tam sim ntawd, koj tuaj yeem xyuas kom meej tias koj cov txhuas tseem nyob hauv qhov zoo rau xyoo tom ntej.
FAQs:
Q: Puas yog aluminium corrode yooj yim?
A: Aluminium yog ib txwm resistant rau corrosion vim yog tsim ntawm oxide txheej ntawm nws nto. Txawm li cas los xij, nyob rau hauv tej yam kev mob, xws li raug dej noo, dej ntsev, los yog acidic ib puag ncig, txhuas tuaj yeem corrode.
Q: Kuv tuaj yeem tiv thaiv corrosion ntawm aluminium nto?
A: Txhawm rau tiv thaiv kev xeb ntawm txhuas qhov chaw, siv cov txheej txheem tiv thaiv, xws li anodized lossis pleev xim rau tag nrho, ntxuav thiab tshuaj xyuas qhov chaw, tsis txhob raug rau qhov chaw hnyav, thiab khaws cov khoom txhuas kom zoo.
Q: corroded aluminium puas tuaj yeem kho?
A: Yog, corroded txhuas tuaj yeem kho tau los ntawm kev tshem tawm cov corrosion nrog ib qho me me abrasive thiab ntxuav qhov chaw nrog kev daws ntawm vinegar thiab dej. Rau corrosion hnyav dua, cov kev pabcuam kho kom zoo yuav tsum tau ua.
