Lo lus nug 1: Dab tsi ua rau 1100 Aluminium ntawv ntawv ci tshwj xeeb haum rau corrosion tsis kam nyob rau hauv hvac system?
Lub corrosion tsis kam ntawm 1100 aluminium ntawv nyiaj hauv HVAC cov ntawv thov stems los ntawm nws cov cim kev sib xyaw ntawm cov khoom siv purity thiab cov yam ntxwv saum npoo. Raws li kev lag luam ntshiab aluminoy muaj 99% txhuas, 1100 series ib txwm ua cov txheej tiv thaiv oxide tiv thaiv thaum raug pa tawm hauv cov pa taws. Qhov no tus kheej kho oxide zaj duab xis, feem ntau 2-5 nanometers tuab, ua raws li ib qho kev txwv tsis raug tiv thaiv ya raws thiab tshuaj tua neeg. Nyob rau hauv hvac tshuab uas condensate tsim kev tsim yog kev ua tsis tau, qhov passive txheej tiv thaiv pitting txawm tias nyob rau hauv ib puag ncig dej hiav txwv mus txog 95% tus txheeb ze vaum. Cov ntawv ci lub siab siab minimizes galvanic corrosion thaum muaj kev sib chwv me me, raws li muaj tsawg dua kev txhawb nqa hluav taws xob txuas ntxiv. Niaj hnub nimno tsim cov txheej txheem ntxiv txhim kho lub innate innensing cov txheej txheem uas ua kom tsis zoo ntawm cov khoom lis cov qauv sib xws uas tuaj yeem yog kev pib corrosion kev pib ua haujlwm. Cov khoom siv thermal conductivity (kwv yees li 235 w / min m) tseem tsis muaj kev cuam tshuam los ntawm kev tiv thaiv hluav taws xob no, ua kom muaj kev txuag hluav taws xob nrawm thoob plaws xyoo ntawm kev pabcuam.
Lo lus nug 2: Cov txheej txheem tsim ntawm HVAC-qib 1100 aluminium ntawv ci txhim kho nws corrosion kev ua haujlwm?
Kev tsim cov tshuaj corrosion-resistant 1100 ntawv nyiaj rau HVAC cov ntawv thov cuam tshuam nrog ntau theem kev tswj hwm-tswj hwm kev ua kom ruaj khov. Txias dov mus rau qhov tuab kawg nkaus (feem ntau 0.0.2 hli) tsim ib qho chaw du todoRography nrog RA roughneters hauv qab no 0.8 micrometers hauv qab thaj chaw cov neeg sawv cev. Tom qab mos mos analaling ntawm 340-400℃tsis tsuas restores duction tsuas yog tseem txhawb txoj kev loj hlob ntawm cov txheej txheem crystalline thiab cov txheej txheem xov xwm ruaj khov. Advanced Foil mills ua haujlwm roj-dawb rolling cov txheej txheem los tiv thaiv hydrocarbon kis tau uas tuaj yeem cuam tshuam oxide adhesion. Cov kev kho mob tom qab muaj xws li cov txheej txheem kev hloov pauv ntawm cov txheej txheem tsis muaj 100,00 txaus Cov tshuab txuas ntxiv ua kom muaj teeb meem sib txawv thoob plaws ntawm cov khoom siv hluav taws xob ntev ntev, nrog cov microstration tam sim no uas tuaj yeem ua rau muaj kev cuam tshuam rau kev ua haujlwm. Kev kuaj cov khoom siv HTM tsawg kawg rau cov ntawv thov HVAC.
Lo lus nug 3: Muaj pes tsawg ib puag ncig hauv hvac systems feem ntau cuam tshuam kev coj tus cwj pwm ntev ntawm 1100 aluminium ntawv nyiaj?
HVAC cov tshuab tam sim no muaj ib puag ncig corrosion uas 1100 aluminium ntawv ci yuav tsum ua ib lub sijhawm tiv thaiv ntau yam kev cuam tshuam. Condensate Chemistry ua pov thawj tshwj xeeb, raws li Evaporator Coil dej ntws feem ntau muaj cov pa dej hiav txwv (los ntawm cov pa dej hiav txwv), thiab cov hmoov av organic). Cov ntawv ci kev ua tiav stems los ntawm nws muaj peev xwm los tswj cov passivation hla pH cov theem li 4 txog 9, tsis zoo li ntau yam uas muaj cov xwm txheej acidic lossis alkaline. Qhov kub thiab txias ntawm -30℃thiab 80℃induces thermal kev ntxhov siab uas tuaj yeem ua kom muaj cov khoom siv hluav taws xob tsawg dua (2300 μID Microbial corrosion zoo dua lwm qhov kev sib tw - Cov ntawv nyiaj tsis muaj-ntxeem tau ua kom tsis txhob muaj biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim biofilm tsim zoo dua li cov txheej txheem ntxig lossis cov khoom sib xyaw. Tej zaum feem ntau hnyav, cov khoom qhia tawm tsam kev zam corrosion nyob rau hauv fin-raj cors pob qij txha, qhov twg capillary conduction tau daig yaam noo rau ncua sij hawm. Kev tshawb fawb teb ntawm ntug hiav txwv HVAC qhia txog kev ntseeg siab tom qab 15 xyoo uas lwm cov khoom siv perfaration nyob rau hauv 5-7 xyoos.
Lo lus nug 4: Li cas ntawm 1100 txhuas ntawv ci piv rau lwm txoj kev tiv thaiv Corrosion rau HVAC Cheebtsam?
Thaum tshuaj ntsuam tawm tsam lwm txoj hauv kev Corrosion tiv thaiv Corrosion, 1100 Txhuas Ntawv ci muaj qhov zoo rau HVAC cov ntawv thov. Piv rau polymer-coated fins, cov ntawv ci pov tseg kom muaj kev txhawj xeeb txog kev txo qis ntawm kev ntsuas siab (courbation cov teebmeem) lossis rwb thaiv tsev rwb thaiv tsev uas txo kev ua kom sov. Tsis zoo li cov khaub noom zinc lossis cov txheej txheem magnesium, nws tsis tas yuav muaj lub sijhawm hloov pauv thiab ua kom muaj kev ua tau zoo nyob rau hauv cov khoom siv nyiaj. Cov khoom siv outperforms 3003 alloy fins nyob rau hauv ib puag ncig ib puag ncig vim nws yooj yim micrortructure, 1100 lub purity mangertration, 1100 lub purity ua kom haum rau cov muaj peev xwm ua kom muaj peev xwm thoob plaws hauv tag nrho saum npoo. Electroplated nickel lossis chrome tas lawm muab cov corrosion sib piv tab sis ntawm 3-5 zaug cov khoom siv ib puag ncig thiab nrog cov txheej txheem tseem ceeb. Feem ntau-overlooked kom zoo dua yog cov ntawv ci qhov sib xyaw ua ke nrog cov txheej txheem hydrothicity uas ua rau muaj kev tiv thaiv tsis yooj yim. Kev ntsuas kev ua neej ua ntej pom tau tias 1100 ntawv sib txuas hauv lub sijhawm nyob rau hauv cov kev tiv thaiv huab cua
Lo lus nug 5: Yav tom ntej tam sim no tau xav tau nyob rau hauv corrosion-resistant aluminium foils rau tom ntej-tiam h0ac tshuab?
Cov evolution ntawm 1100 aluminium ntawv nyiaj rau HVAC cov ntawv thov yog kev nce qib nrog ob txoj hauv kev tshiab. Nanostructured oxide txheej engineering enging, nrog cov kws tshawb fawb kev ua si ntawm cov kab ke Lwm qhov tshwm sim tshiab cuam tshuam txog kev tsim cov qauv dej micro-uas cuam tshuam txog ntawm 70% piv rau cov ntawv ci du. Alloy kev loj hlob tsom rau ultra-siab purity variants (99.3% AL) nrog txo cov kev pabcuam Cathodic intermetallic, muaj peev xwm ua ob npaug rau lub neej nyob hauv cov cua. Ntse cov ntsiab lus ci hauv embed embopic ph sensors uas siv conductive polymers uas hloov cov xim thaum kev saib xyuas corrosion, ua kom pom kev txij nkawm. Tej zaum feem ntau hloov pauv yog kev sib koom ua ke ntawm graphene-txhim kho cov txheej txheem ua haujlwm thaum muaj cov nqi thermal los ntawm kev txiav txim siab ntawm qhov ntau. Raws li HVAC tshuab hloov zuj zus mus rau hauv lub taub hau qis dua zoo li R454b uas ua haujlwm nyob rau ntawm cov tub yees siab siab dua ntawm cov roj ntsha tau los ntau lawm.
