Nkag siab corrosion tsis kam nyob rau hauv Aluminium Profiles: Kev Xav Tau Kev Xav Tau thiab Kev Txij Nkawm

Txhuas tau siv dav thoob plaws ntau yam kev lag luam vim nws cov ntau cov khoom ua tau zoo, tshwj xeeb yog nws corrosion tsis kam. Qhov uas tau txais kev muaj peev xwm ua rau muaj kev tiv thaiv tsis zoo rau lub sijhawm ua tiav cov txheej txheem zoo heev rau ob qho qauv thiab dai kom zoo nkauj. Kev tu ncua ntev thiab kev txij nkawm tsis tshua muaj ntawm lawv cov kev tshwj xeeb tsis kam nrog corrosion, uas yog qhov tseem ceeb rau kev ua kom ntev thiab txo cov nqi ntev thiab rov qab. Hauv tsab xov xwm no, peb yuav tshawb txog kev kawm txuj ci qab txhuas, cov laj thawj vim li cas Aluminium profiles yog qhov zoo tagnrho hauv kev thov ib puag ncig.

 

Dab tsi ua rau txhuas corrosion - tiv taus?
Txhawm rau nkag siab txog kev xeb tsis kam ntawm Aluminium Profiles, nws yog ib qho tseem ceeb kom xub tuav lub hauv paus ntawm corrosion nws tus kheej. Corrosion yog cov txheej txheem ntuj los ntawm cov ntaub ntawv twg, feem ntau yog hlau, tsis zoo vim lawv ib puag ncig, feem ntau muaj kev ya raws, oxygen, lossis ntsev. Kev xeb ntawm cov hlau feem ntau tsis muaj zog ua rau lawv cov qauv, txo lawv cov khoom siv tshuab thiab ua rau lawv tsis ntseeg lub sijhawm.

 

Aluminium yog cov tiv taus zoo heev vim yog tsim ntawm ib txheej roj nyias, tiv thaiv oxide txheej rau ntawm nws cov npoo thaum uas raug huab cua. Daim ntawv oxide no txheej yuav luag tam sim ntawd thaum cov hlau los rau hauv kev sib cuag nrog oxygen thiab ua raws li cov nyom uas tiv thaiv kev ua kom loj oxidation. Tsis zoo li lwm cov hlau, xws li hlau lossis hlau, qhov uas ua rau xeb tau nkag mus rau lub ntsej muag yooj yim thiab ua rau muaj kev puas tsuaj loj heev-}} kev kho yog tias nws tau khawb lossis puas. Qhov tshwj xeeb no ua kom ntseeg tau tias cov profatines no nyob ruaj khov thiab ua haujlwm ntev kom ntev yam tsis muaj kev cuam tshuam tseem ceeb.

 

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm txhuas kuj tseem yog lub luag haujlwm tseem ceeb hauv nws txoj kev xeb tawm tsam. Lub xub ntiag zoo li silicon, tooj liab, thiab magnesium tuaj yeem txhim kho kev txhim kho corrosion, cia nws ua tau zoo dua nyob rau qee qhov chaw, xws li cov tub rog lossis chaw nyob. Cov versatility ntawm txhuas alloys txuas ntxiv ua kom lawv cov kev haum rau ntau cov ntawv thov, los ntawm tsev qauv qauv rau kev kho tsheb thiab aerospace Cheebtsam.

 

Kev kawm txuj ci qab txhuas yog corrosion tsis kam
Lub corrosion tsis kam ntawm txhuas tuaj yeem ntaus nqi rau cov txheej txheem hu ua passivation. Thaum aluminium yog tshwm sim rau cov pa, nws cuam tshuam nrog cov huab cua los ua ib qho xim oxide nyias, feem ntau tsuas yog ob peb cov nanometers tuab. Cov roj oxide no, ua cov roj oxide aluminium (al₂o₃), yog ruaj khov thiab ua raws li txoj kev thaiv, tiv thaiv ntxiv ntawm cov hlau txuas mus rau ib puag ncig.

 

Ib qho ntawm cov ntsiab lus tseem ceeb ntawm cov oxide txheej yog tias nws ua kom ruaj khov rau cov npoo txhuas thiab lwm cov neeg sawv cev ntawm cov hlau hauv qab. Nyob rau hauv cov ntaub ntawv khawb lossis kev puas tsuaj me, cov oxide txheej hloov kho sai sai, tiv thaiv cov hlau los ntawm kev kis rau corrosive cov khoom rau ncua sij hawm. Qhov no tus kheej - kho cov cuab yeej uas txhuas tseem muaj nyob rau lwm qhov chaw uas lwm cov khoom yuav ua rau pom sai sai.

 

Ntxiv nrog rau cov txheej txheem uas muaj kev hla dhau, txhuas alloys tuaj yeem kho tau ntxiv los ntawm cov txheej txheem xws li anodizing. Anodizing yog ib qho kev kho mob Electrochemical uas tuab cov txheej txheem tiv thaiv oxide, txhim kho cov khoom siv tau xeb. Cov txheej txheem no feem ntau siv nyob rau hauv cov ntawv thov uas aluminium yuav raug huab cua huab cua, xws li nyob rau hauv cov ntawv thov archabitectural thiab tsheb.

 

Yam cuam tshuam los ua txhuas cov corrosion tsis kam
Thaum lub sij hawm txhuas profiles yog inherently resistant rau corrosion, ntau yam tuaj yeem cuam tshuam lawv kev ua tau zoo dhau sijhawm. Cov hauv qab no yog qee qhov tseem ceeb hloov uas cuam tshuam rau kev xav tau ntev thiab kev txij nkawm uas xav tau ntawm Aluminium Profiles:

 

Ib puag ncig ib puag ncig
Qhov chaw nyob rau hauv uas aluminium profiles tau siv ua lub luag haujlwm tseem ceeb hauv lawv cov corrosion tsis kam. Piv txwv li, nthuav tawm rau Salishwater hauv cov txheej txheem marine muaj peev xwm ua kom nrawm txheej txheem corrosion, li ntsev ua raws li kev ua txhaum rau cov hlau. Txawm li cas los xij, Aluminium qhov tsis kam rau corrosion hauv Salosater nyob tseem ceeb dua li ntawm ntau cov hlau. Qhov no yog vim li cas txhuas feem ntau yog siv rau cov ntawv thov marine, xws li nkoj hulls thiab dej hiav txwv infrrastructure.

 

Ntawm qhov tod tes, txhuas txoj kev tiv thaiv corrosion yuav raug txo kom tsawg hauv cov acidic muaj zog lossis ib puag ncig. Piv txwv li, hauv cov chaw muaj cov tshuaj lossis cov kua qaub yog tam sim no, tshwj xeeb txheej lossis cov kev kho mob lossis cov txheej txheem ncaj ncees.

 

Cov kev kho saum npoo thiab txheej
Aluminium profiles tuaj yeem ua kom zoo dua nyob rau hauv cov nqe lus ntawm corrosion tsis kam los ntawm ntau yam kev kho mob thiab txheej txheej. Cov kev kho mob tshaj plaws yog anodizing, uas tsis tsuas yog kho cov khoom siv corrosion tsis kam tab sis kuj tso cai rau kev customization tsis zoo. Anodized Aluminium muaj cov roj oxide thicker, ua rau nws tiv taus corrosion thaum txhim kho qhov tsos pom.

 

Ntxiv nrog rau anodizing, txhuas tuaj yeem sib xyaw nrog cov xim tiv thaiv lossis cov xov xwm los muab cov txheej ntxiv ntawm kev tiv thaiv. Cov txheej txheej no tuaj yeem pab tau tshwj xeeb rau kev tiv thaiv txhuas los ntawm kev ua kom muaj huab cua ib puag ncig, xws li cov av noo lossis cov pa vaum.

 

Galvanic corrosion
Thaum txhuas yog siv nyob rau hauv kev sib txuas nrog lwm cov hlau, Galvanic corrosion tuaj yeem tshwm sim yog cov hlau muaj hluav taws xob thiab raug cov hluav taws xob, xws li dej. Galvanic corrosion tshwm sim thaum ob tug dissimilar metrals corrode ntawm tus nqi sib txawv. Txhawm rau tiv thaiv qhov no, nws yog ib qho tseem ceeb kom cais cov txhuas los ntawm lwm cov hlau uas muaj feem cuam corrosion tsis kam lossis thov kev tiv thaiv kev tiv thaiv kom tsis txhob muaj kev sib cuag.

 

Kev hloov pauv kub
Huab cua ntau hloov kuj tuaj yeem cuam tshuam kev ua tau zoo ntawm Aluminium Profiles. Hauv cov cheeb tsam uas muaj qhov kub kub hloov pauv, kev nthuav dav thiab kev cog lus ntawm cov khoom tuaj yeem ua rau muaj cov tshuaj tiv thaiv oxide. Txawm li cas los xij, Aluminium lub teeb yuag thiab muaj peev xwm hloov kho qhov kub thiab txias yam tsis muaj kev cuam tshuam dab tsi uas feem ntau yog feem ntau ntawm kev txhawj xeeb piv rau lwm yam khoom siv li hlau.
