1.What yog cov tseem ceeb thev naus laus zis rau kev txhim kho galvanized steel corrosion?
Txheej Txheem Txhim Kho
Zinc-Aluminium Txheej
Kev kho tus kheej: mg²⁺ migrates los sau cov khawb
Corrosion Kuj: Kev Tshuaj Tsuag Ntsev Kev Tshuaj Tsuag> 1500H.
Kuj mus rau gravel cuam tshuam: hatness nce los ntawm 30%.
Kev Tiv Thaiv Kom Yooj Yim Rau Cov Khoom Tseem Ceeb
Roj teeb Pob Installation Taw tes
Insulating Ceramic Txheej yog siv los cais hluav taws xob muaj peev xwm sib txawv (zinc hmoov)
High voltage harness vias: Txhaj pwm puab EPDM Sealing nplhaib + Zinc-Nickel Plated Bracket
2.Qhov kev sib koom tes yog qhov kev sib koom tes rau kev tsim kho corrosion corrosion?
Cov txheej txheem los tiv thaiv corrosion
Kev Siv Dej Ua Kom Zoo: Txoj kab nqes ntawm Chassis Daim Ntawv Qhia Kev Grooveis yog ntau dua lossis sib npaug zos kom tsis txhob muaj cov chaw tso dej (xws li ntug ntawm lub roj teeb pob)
Zam kev sib tsoo: cov txuas siv laser vuam es tsis txhob siv vuam vuam (txo qhov khoob> 0.2 hli)
Cov Khoom Sib Nraus: PP / EPDM gaskets yog siv ntawm txhuas qhov chaw thiab galvanized steel los thaiv galvanic corrosion
Electrochemical tiv thaiv
Cov tshuaj tiv thaiv Cathodic: Magnesium Alloy Remoy Anode yog ntsia rau ntawm lub roj teeb pob bracket
Kev tiv thaiv muaj peev xwm tswj hwm ntawm -1.05v ~ -1.10V vs
Stray tam sim no tswj: High-voltage kab tiv thaiv txheej txheej av tsis kam<0.1Ω
Chassis txau cov txheej txheej (saum npoo ua hauj lwm 10⁴-10⁶ω) muaj peev xwm sib npaug
3.Qhov yog qhov tshwj xeeb corrosion nyuaj ntawm lub tsheb tshiab lub tsheb chassis?
Tshuaj lom neeg corrosion: Roj teeb electrolyte togage
Electrochemical corrosion: stray tam sim no nyob rau hauv high-voltage system
Cov Khoom Siv Kho Mob: tsis ua hauj lwm ntawm cov roj teeb pob uas tau muab rau kev sib tw hauv zos
Qhov kub thiab txias: Cov roj teeb ceev dua
4.Qhov tus nqi sib piv rau lwm txoj kev xaiv li cas?
Txhim kho tus nqi nce ntawm galvanized steel los ntawm 15% thiab muab ib qho kev tiv thaiv lub neej ntawm 12 xyoos.
Tus nqi ntawm txhuas alloy Chassis tau nce los ntawm 40%, thiab cov anti-corrosion lub neej yog 15 xyoos.
Tus nqi ntawm cov roj carbon fiber ntau ntxiv nce ntxiv los ntawm 200%, thiab cov kev tiv thaiv corrosion lub neej 20 xyoo.
5.Qhov kev thov ntawm Galvanized steel nyob rau hauv tshiab lub zog chassis yuav tsum tau peb npaug opectization ntawm "plating alloying + ntau txheej txheej + qauv synergy". Dab tsi yuav tsum tau ua raws?
Lub hauv paus txheej: zinc-txhuas-hlau nplaum txheej (corrosion tsis kam nce 3 zaug)
Txheej txheem txheej txheem: Cathode elecophoresis + Axol-Pob zeb cuam tshuam PVC + Insulating Ceramic (Qhov Tseem Ceeb)
Kev Tsim Qauv: Siv Tshuaj Nrog Kev Siv Khoom Siv Luam Tawm + Galvanic Kev Rho Tawm + Kev Txom Nyem Anode
Thaum kawg ua tiav lub neej corrosion ntau dua 15 xyoos, nrog cov nqi uas tswj tau, uas yog qhov xav tau zoo rau kev ntsuas kev ua tau zoo thiab raug nqi. Rau cov cheeb tsam muaj kev pheej hmoo siab, nws raug nquahu kom tau hloov ib nrab nrog 6061-t6 aluminium alloy txhawm rau txhim kho kev nyab xeeb.
