Q1: Dab tsi yog cov hluav taws xob ua rau 1100 aluminium foil txoj kev xaiv zoo tshaj plaws rau cov ntawv teev rwb thaiv tsev hauv zog?
Qhov tshwjxeeb rwb thaiv tsev kev ua tau zoo ntawm 1100 Aluminium ntawv nyiaj los ntawm nws cov cim kev sib xyaw ntawm cov khoom siv purity thiab cov yam ntxwv lub cev. Raws li kev lag luam ntshiab aluminoy muaj 99% aluminium, nws tsis muaj cov ntsiab lus alloy uas feem ntau tsim txoj hauv kev hauv lwm cov hlau. Thaum siv los ua ib qho kev thaiv kev rwb thaiv tsev, cov ntawv ci lub cev ua yeeb yam oxide txheej ua haujlwm tshaj plaws lub luag haujlwm tseem ceeb tshaj plaws. Qhov no microscopically nyias oxide zaj duab xis, tsuas yog hais txog 4-5 nanometers tuab nyob rau hauv ib txwm mob, cov ntaub spontaneously thaum lub hlau nto yog nthuav tawm Dab tsi ua rau nws zoo kawg yog li cas cov oxide txheej coj nyob rau hauv kev ntxhov siab hluav taws xob.
Hauv kev siv cov ntawv thov tam sim no, txheej oxide txheej ua ib qho dielectric barrier nrog kev puas tsuaj tsis zoo. Tus qauv amorphous tuaj yeem tiv thaiv hluav taws xob sib txuas txog 600 volts ib micron ua ntej tshwm sim. Qhov no txhais tau hais tias txawm tias kev ua lag luam thoilest muaj cov ntawv ci (nyob ib ncig ntawm 6 microns) tuaj yeem ua kom nyab xeeb ntau puas ntau pua volts. Oxide lub siab tiv taus (10¹⁴ Olem tebchaws Electron ntws, thaum nws cov tshuaj muaj kev ntxhov siab nyob rau hauv lub caij nyoog hluav taws xob kev ntxhov siab. Lwm qhov txiaj ntsig yog cov ntawv ci cov thermal conductivity, uas tso cai rau cua sov districation - ib qho cuab yeej feem ntau polymer insulators tsis muaj. Qhov kev sib txuam ntawm hluav taws xob tsis kam thiab cov kev tswj hwm cua sov ua rau 1100 ntawv nyiaj tsis tseem ceeb hauv cov hluav taws xob hloov kho hauv lub zog.
Q2: Yuav ua li cas ua cov txheej txheem tsim ntawm 1100 Aluminium ntawv ua kom zoo ua kom zoo dua nws txoj kev ua tau zoo rau hluav taws xob rwb thaiv tsev lub hom phiaj?
Cov txheej txheem ntau lawm rau hluav taws-qib-qeb-qib 1100 ntawv ci teeb meem ntau cov kauj ruam tshwj xeeb uas txhim kho nws lub rwb thaiv tsev. Los ntawm thawj zaug smelting txheej txheem, kev saib xyuas ntxiv yog coj los txo cov xim hlau tsis zoo uas tuaj yeem tsim cov kev sib txuam. Lub cev tsis zoo ua kom zoo dua ua kom zoo li cov hlau thiab sillicon hauv qab no 0.1%, raws li cov no tuaj yeem tsim lub zog diellecet. Thaum txuas ntxiv ua pov thawj, hluav taws xob stirring tsim ib qho qauv zoo-lis cov qauv uas tiv thaiv cov chaw tsis muaj zog hauv cov ntawv ci kawg.
Tus txheej txheem txias dov tsim nyog tshwj xeeb mloog. Los ntawm kev ua tib zoo tswj kev txo cov zauv sib txheeb (feem ntau 90-95% rau cov qib rwb thaiv tsev), cov tuam ntxhab ua tiav qhov kev pom ntawm cov ntawv ci thiab cov khoom siv nto. Txhua kis dhau los ntawm cov pob zeb dov ua tiav, uas daws cov kev ntxhov siab sab hauv kev ntxhov siab - kev ua tsis tiav ntawm kev ntxhov siab. Qhov kawg Annealing ntawm 350-400℃txhim kho cov qauv recrystallized tag nrho uas muab cov ntawv muab cov ntawv sau ntxiv thaum tswj kev ruaj khov. Kev kho deg yog ib qho tseem ceeb heev; Cov khoom siv hluav taws-qib muag tau txais cov tshuaj tshwj xeeb uas tuab uas ua tuab thiab ruaj khov cov txheej oxide ib txwm. Qee tus hwm hwm txawm tias cov ntshav hluav taws xob uas tsis tau txais hluav taws xob los tsim cov tshuaj dag ntxias oxide zaj duab xis rau 20 microns tuab rau cov ntawv thov high-voltage.
Q3: Dab tsi yog qhov tseem ceeb ntawm kev siv 1100 aluminium ntawv nyiaj tshaj cov yeeb yaj kiab polymer hauv hluav taws xob siab hluav taws xob?
Thaum polymer cov yeeb yaj kiab zoo li tus tsiaj lossis PI muaj cov hluav taws xob rwb thaiv tsev rau ntau xyoo, 1100 aluminium ntawv muaj ob peb qhov chaw ua haujlwm thermal. Qhov tseem ceeb tshaj plaws yog qhov kub tsis kam. Tsis zoo li cov ntaub ntawv organic uas pib decomposing ntawm 150-300 degree, txhuas oxide tseem ruaj khov rau nws lub siab melting ntawm 2072 degree. Qhov no ua rau 1100 ntawv ci zoo tagnrho rau cov ntawv thov zoo li lub cev muaj zog windings lossis lub zog hluav taws xob uas qhov chaw hauv nruab nrab tau tshaj 200 degree. Cov ntawv ci yuav tsis carbonize los yog tso cov pa roj hmab thaum overheated, ib qho tseem ceeb rau kev nyab xeeb hauv cov khoom siv hluav taws xob siab.
Lwm qhov zoo dua yog noo noo tsis kam. Polymer zaj duab xis feem ntau nqus tau cov nyiaj ntawm cov av noo, uas tuaj yeem txo lawv lub zog ua kom tau lub sijhawm. Txhuas oxide yog inheramed hydrophobic thiab tsis muaj kev cuam tshuam los ntawm ya raws, tswj cov kev ua tau zoo sib xws txawm tias muaj kev thaj yeeb nyab xeeb. Cov ntawv ci tseem muab cov khoom siv zoo dua rau kev tawm tsam ib nrab - lub ntsej muag hluav taws xob me me uas maj mam lwv cov ntaub ntawv. Thaum cov kev tawm no tuaj yeem tsim cov pa roj carbon taug kev hauv polymers, lawv tsuas hloov kho oxide txheej ntawm txhuas ntawm txhuas ntawm txhuas ntawm txhuas ntawm txhuas ntawm txhuas cov khoom siv insulating. Tsis tas li ntawd, txhuas ntawv ci muab hluav taws xob tiv thaiv uas polymers tsis tuaj yeem phim, kev cuam tshuam kev cuam tshuam hauv cov hluav taws xob sib xyaw.
Q4: Cas lub teeb yuag ntawm 1100 aluminium no aluminium no aluminium no almium rwbuis system tsim qauv?
Qhov teeb pom kev zoo ntawm 1100 Aluminium Ntawv Nyiaj (2.7 g / cmà density) Rwb thaiv tsev rwb thaiv tsev enulationing hauv ob peb txoj kev tseem ceeb. Thawj zaug xav txog kev siv daim ntawv thov ua haujlwm ib qho, qhov chaw txhua gram suav. Hloov cov ntaub ntawv rwb thaiv tsev nrog cov ntawv ci txhuas tuaj yeem txo cov luj hloov hluav taws xob los ntawm 40-60 txhim kho roj efficiency hauv cov tshuab hluav taws xob. Cov ntawv ci kho tshuab zog tso cai rau cov kev tsim kho tinener yam tsis muaj kev ua kom muaj qhov sib luag - ib micron ntawm ntau cov polymers, ntawm tsuas yog ib feem peb qhov hnyav.
Qhov hnyav no kom tau zoo dua ua ntau cov cuab yeej ua kom haum. Lub zog capacitors siv txhuas ntawv deleesectric tuaj yeem ua tiav 30% ntau lub zog ua kom ruaj khov nyob rau hauv tib lub ntim piv rau cov yeeb yaj kiab polymer. Cov ntawv ci qhov yooj yim ua kom yooj yim txhawb kev ua haujlwm winding uas yuav ua tsis tau cov khoom siv ruaj khov, pub cov engineers kom ua tau zoo sib nqus flux paths hauv transformers. Hauv nruab txuas ntxiv hluav taws xob zoo li cua tshuab, txo cov hluav taws xob rwb thaiv tsev txo qis thauj khoom, txuas ntxiv cov kev tu. Tej zaum tseem ceeb tshaj plaws, cov ntawv ci lub teeb yooj yooj yim txhim kho cov yob loj nrog kev siv zog loj, txo lub sijhawm ua kom raug haujlwm thiab lub sijhawm ua haujlwm kom ruaj khov.
Q5: Cov tshuab hluav taws xob tawm hluav taws xob tau txhim kho hluav taws xob rwb thaiv tsev muaj peev xwm ntawm 1100 aluminium ntawv ci rau cov ntawv thov txuas ntxiv?
Ob peb txiav cov thev naus laus zis yog thawb cov ciaj ciam ntawm dab tsi 1100 Aluminium ntawv ci tuaj yeem ua tiav hauv hluav taws xob rwb thaiv tsev. Nanostructuring tswv yim tam sim no cia precise engise ntawm oxide txheej porosity thiab tuab ntawm atomic nplai. Los ntawm cov txheej txheem anodization siv pulsed DC lub zog, cov neeg tsim khoom tuaj yeem tsim cov kab yeeb yaj kiab oxogred uas cuab cov ntxiab uas ua rau direelectric los ntawm 30-40%. Lwm qhov sib tsoo cuam tshuam nrog graphene-enhanced ntawv ci, qhov twg ib-txheej duab vaab kev txiav txim siab thaum ntxiv cov kev tshwj xeeb ua haujlwm.
Ntshav plasma immersion ion immantation sawv cev lwm cov frontier. Los ntawm BROMBARDING NTAWV Nyiaj SURFACES NROG HIGHOLERS MAS LOS NTAWM METALLIC ALLOINDY, tshem tawm cov kev txwv dav dav Rau cov ntawv thov high-zaus, cov kws tshawb nrhiav tau txhim kho cov ntawv nyiaj nrog laser-induced perienctric poob ntawm GHZ zaus. Tej zaum feem ntau txaus siab yog tus kheej kho cov ntawv ci concorporating microcapsules cov txheej txheem uas tau kho cov pa oxide uas tau kho kom haum los ntawm kev ua kom zoo los ntawm kev ua kom zoo los ntawm kev ua kom zoo los ntawm kev ua kom zoo nkauj Cov kev hloov tshiab no ua kom muaj 1100 Txhuas Ntawv ci yuav nyob ntawm qhov ua ntej ntawm cov khoom siv hluav taws xob zoo rau yav tom ntej.
