Qhov tseem ceeb ntawm Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob hauv Hluav Taws Xob

1. Taw qhia

Cov tsheb hluav taws xob (EVs) tau hloov pauv txoj hauv kev uas peb mus ncig, muab kev ntxuav kom huv thiab muaj txiaj ntsig zoo dua rau cov tsheb uas siv roj hluav taws xob. Tab sis tom qab lub nrawm nrawm thiab ua haujlwm ntsiag to ntawm EV yog ib qho tseem ceeb ntawm cov khoom uas feem ntau mus tsis pom -cov kab hluav taws xob siab. Cov xov hlau no yog lub luag haujlwm rau kev xa hluav taws xob nruab nrab ntawm lub roj teeb, lub cev muaj zog, thiab ntau yam khoom siv hluav taws xob, ua haujlwm raws li lubtxoj siantawm lub tsheb lub zog system.

Raws li EVs tau dhau los ua ntau dua, cov kev xav tau ntawm cov kab hluav taws xob hluav taws xob tau nce ntxiv. Kev nyab xeeb, kev ua tau zoo, thiab kav ntev yog qhov kev txhawj xeeb tseem ceeb, ua rau kev xaiv cov khoom siv yog qhov tseem ceeb. Yog li, cov ntaub ntawv twg yog qhov zoo tshaj plaws rau high-voltage EV thaiv? Cia peb ua kom tawg.

2. Hom High-Voltage Hlau Rwb Thaiv Tsev Khoom

Txhawm rau kom muaj kev nyab xeeb thiab ua haujlwm tau zoo, cov xaim hluav taws xob siab yuav tsum yogrwb thaiv tsevnrog cov ntaub ntawv zoo uas tuaj yeem tiv taus cua sov, hluav taws xob kev ntxhov siab, thiab kev sib tw ib puag ncig. Ntawm no yog cov ntaub ntawv rwb thaiv tsev feem ntau siv hauv EV high-voltage xov hlau:

2.1. Polyvinyl Chloride (PVC)

PVC yog ib zaug siv dav vim nwstus nqi qis thiab zoo mechanical zog. Nws yog ib qho yooj yim rau txheej txheem thiab muaj dlej durability. Txawm li cas los xij, PVC muaj qee qhov teeb meem tseem ceeb:

• Nws muaj cov tshuaj chlorine, uas ua rau muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv.
• Nws muaj cov cua sov tsis zoo, uas tuaj yeem ua rau degradation nyob rau hauv qhov kub thiab txias.
• Nws zoo li tawv thiab tawg thaum lub sijhawm, tshwj xeeb tshaj yog nyob rau hauv huab cua txias.

Vim tias cov teeb meem no, ntau lub tuam txhab tau txav deb ntawm PVC hauv kev pom zoo ntawm cov khoom siv ntau dua.

2.2. Cross-Linked Polyolefin (XLPO)

XLPO yog ib qho ntawm cov kev xaiv saum toj kawg nkaus rau high-voltage EV xov hlau. Nov yog vim li cas:

• Superior tshav kub tsis kam:Nws tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj degrading.
• Zoo heev mechanical zog:Resistant rau dabtsi yog khoov, ncab, thiab cuam tshuam.
• Durability:Ntev lifespan vim nws tsis kam mus rau kev laus thiab hnav.
• Chemical stability:Resistant rau corrosion thiab hnyav ib puag ncig.

Ib tug drawback yog nwsnplaim taws kuj tsis muaj zog, tab sis halogen-free flame-retardant XLPO feem ntau yog siv los daws qhov teeb meem no. Vim nws qhov kev ua tau zoo, XLPO tam sim no yog qhov kev xaiv tseem ceeb rau EV cov xaim hluav taws xob siab.

2.3. Thermoplastic Elastomer (TPE)

TPE yog cov khoom siv tau yooj yim thiab cov txheej txheem yooj yim uas sib txuas cov khoom ntawm cov roj hmab thiab yas. Nws muaj:

• Zoo elasticityntawm qhov kub thiab txias.
• Moldability, ua kom yooj yim rau hauv cov qauv hlau sib txawv.

Txawm li cas los xij, nws muaj qee qhov tsis muaj zog:

• Tsawg hnav tsis kampiv rau XLPO.
• Kev ua haujlwm tsis zoo ntawm qhov kub thiab txias, ua rau nws tsis haum rau kev xav tau EV ib puag ncig.

Vim tias cov kev txwv no, TPE tsis yog qhov kev xaiv zoo tshaj plaws rau kev xaim hluav taws xob siab tab sis tseem siv tau rau qee yam kev siv.

3. Cov qauv rau EV High-Voltage Hlau

Txhawm rau kom muaj kev nyab xeeb thiab kev ntseeg siab, cov xaim hluav taws xob siab hauv EVs yuav tsum ua raws li cov qauv kev lag luam nruj. Nov yog qee cov qauv tseem ceeb siv thoob ntiaj teb:
