Ib qho hluav taws xob ruaj khov thiab sib npaug tsis yog tsuas yog nyob ntawm cov qauv zoo thiab kev ua tau zoo ntawm cov xov hlau xwb, tab sis kuj nyob ntawm qhov zoo ntawm ob qho tseem ceeb hauv cov xov hlau: cov khoom siv rwb thaiv tsev thiab cov ntaub ntawv sheath.
Hauv cov phiaj xwm siv hluav taws xob tiag tiag, cov xov hlau feem ntau raug rau cov xwm txheej ib puag ncig hnyav rau lub sijhawm ntev. Txij li kev raug UV ncaj qha, hluav taws kub hauv tsev, kev faus hauv av, txias heev, mus rau nag hnyav, txhua yam ua rau muaj kev cov nyom rau cov ntaub ntawv rwb thaiv tsev thiab cov ntaub thaiv ntawm cov xov hlau photovoltaic. Cov ntaub ntawv feem ntau siv suav nrog polyolefin cross-linked (XLPO), polyethylene cross-linked (XLPE), thiab polyvinyl chloride (PVC). Txhua yam ntawm cov ntaub ntawv no muaj cov yam ntxwv sib txawv uas haum rau cov xwm txheej ib puag ncig sib txawv thiab cov kev xav tau ntawm cov phiaj xwm. Lawv tiv thaiv kev poob hluav taws xob thiab luv luv, thiab txo cov kev pheej hmoo xws li hluav taws lossis hluav taws xob poob siab.
PVC (Polyvinyl Chloride):
Vim nws yooj ywm, tus nqi nruab nrab, thiab yooj yim ua, PVC tseem yog cov khoom siv raw siv rau kev rwb thaiv tsev cable thiab sheathing. Ua ib yam khoom siv thermoplastic, PVC tuaj yeem yooj yim pwm rau ntau yam duab. Hauv cov tshuab photovoltaic, nws feem ntau raug xaiv ua cov khoom siv sheath, muab kev tiv thaiv kev sib txhuam rau cov xov hlau sab hauv thaum pab txo cov peev nyiaj tag nrho.
XLPE (Cross-linked Polyethylene):
Ua los ntawm kev siv cov txheej txheem sib txuas silane tshaj lij, cov neeg sawv cev silane coupling raug ntxiv rau hauv polyethylene los txhim kho lub zog thiab kev tiv taus kev laus. Thaum siv rau cov cables, cov qauv molecular no txhim kho lub zog thiab kev ruaj khov ntawm cov khoom siv, ua kom muaj kev ruaj khov nyob rau hauv huab cua hnyav.
XLPO (Cross-linked Polyolefin):
Tsim los ntawm kev siv cov txheej txheem tshwj xeeb irradiation cross-linking, cov polymers linear raug hloov mus ua cov polymers ua tau zoo nrog cov qauv network peb-seem. Nws muaj kev tiv thaiv UV zoo heev, tiv thaiv thermal, tiv thaiv txias, thiab cov khoom siv kho tshuab. Nrog kev ywj pheej ntau dua thiab tiv thaiv huab cua dua li XLPE, nws yooj yim dua rau kev teeb tsa thiab maneuver hauv cov qauv nyuaj - ua rau nws tsim nyog rau cov vaj huam sib luag hnub ci ru tsev lossis cov kab ke hauv av.
Peb cov XLPO compound rau cov cables photovoltaic ua raws li RoHS, REACH, thiab lwm yam qauv thoob ntiaj teb ib puag ncig. Nws ua tau raws li qhov yuav tsum tau ua ntawm EN 50618: 2014, TÜV 2PfG 1169, thiab IEC 62930: 2017, thiab tsim nyog rau kev siv rau hauv cov txheej rwb thaiv tsev thiab cov txheej sheath ntawm cov cables photovoltaic. Cov khoom siv no ua kom muaj kev nyab xeeb ib puag ncig thaum muab cov txheej txheem ua tiav zoo heev thiab qhov chaw extrusion du, txhim kho kev ua haujlwm ntawm cov cable thiab cov khoom sib xws.
Kev Tiv Thaiv Hluav Taws thiab Dej
XLPO, tom qab kev sib txuas ntawm kev cuam tshuam nrog hluav taws xob, muaj cov yam ntxwv tiv taus hluav taws. Nws tswj tau qhov ruaj khov hauv qhov kub thiab txias siab, txo qhov kev pheej hmoo ntawm hluav taws. Nws kuj txhawb nqa AD8-rated dej tsis kam, ua rau nws haum rau qhov chaw noo noo lossis los nag. Qhov sib piv, XLPE tsis muaj kev tiv taus hluav taws thiab zoo dua rau cov kab ke uas xav tau dej tsis kam. Txawm hais tias PVC muaj peev xwm tua nws tus kheej, nws cov hluav taws tuaj yeem tso cov pa roj nyuaj dua.
Kev Lom Zem & Kev Cuam Tshuam Rau Ib Puag Ncig
XLPO thiab XLPE yog cov khoom siv uas tsis muaj halogen, tsis muaj pa luam yeeb ntau uas tsis tso cov pa roj chlorine, dioxins, lossis cov pa roj corrosive thaum lub sijhawm hlawv, ua rau muaj kev phooj ywg zoo rau ib puag ncig. Ntawm qhov tod tes, PVC tuaj yeem tso cov pa roj phem rau tib neeg thiab ib puag ncig thaum muaj qhov kub siab. Ntxiv mus, qib siab ntawm kev sib txuas hauv XLPO ua rau nws siv tau ntev dua, pab txo cov nqi hloov pauv thiab kev saib xyuas mus sij hawm ntev.
XLPO & XLPE
Cov Xwm Txheej Thov: Cov chaw tsim hluav taws xob hnub ci loj hauv cov cheeb tsam uas muaj hnub ci muaj zog lossis huab cua hnyav, cov ru tsev hnub ci lag luam thiab kev lag luam, cov hnub ci hauv av, cov haujlwm tiv thaiv xeb hauv av.
Lawv qhov kev ywj pheej txhawb nqa cov qauv nyuaj, vim tias cov cables yuav tsum tau hla cov teeb meem lossis hloov kho ntau zaus thaum lub sijhawm teeb tsa. XLPO lub zog ruaj khov nyob rau hauv huab cua hnyav ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov cheeb tsam uas muaj kev hloov pauv kub thiab ib puag ncig hnyav. Tshwj xeeb tshaj yog nyob rau hauv cov haujlwm photovoltaic nrog kev thov siab rau kev tiv thaiv hluav taws, kev tiv thaiv ib puag ncig, thiab lub neej ntev, XLPO sawv tawm ua cov khoom siv nyiam.
PVC
Cov Xwm Txheej Siv: Kev teeb tsa hnub ci sab hauv tsev, cov tshuab hnub ci ntxoov ntxoo, thiab cov haujlwm hauv huab cua sov nrog lub hnub ci tsawg.
Txawm hais tias PVC muaj qhov tsis kam rau UV thiab cua sov qis dua, nws ua haujlwm tau zoo hauv qhov chaw uas raug tshav ntuj nruab nrab (xws li cov kab ke sab hauv tsev lossis cov kab ke sab nraum zoov uas muaj qhov ntxoov ntxoo ib nrab) thiab muaj kev xaiv pheej yig.
