Qhov kev thov kom muaj zog dua tshiab ntau zuj zus yog qhov ua rau muaj kev siv zog hnub ci dav dav. Ib qho ntawm cov khoom tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm zoo thiab kev ruaj khov ntawm cov vaj huam sib luag hnub ci yog lub hnub ci backsheet. Hauv cov blog no, peb yuav tshawb nrhiav cov khoom thiab kev siv ntawm lub hnub ci backsheets, hais txog lawv qhov tseem ceeb hauv kev lag luam hnub ci.
Lub hnub ci backsheet yog dab tsi?
Lubdaim ntawv qhia hnub ci yog txheej tiv thaiv nyob rau sab nraub qaum ntawm lub vaj huam sib luag hnub ci. Nws ua haujlwm ua ib daim thaiv kev tiv thaiv, tiv thaiv cov photovoltaic (PV) cells los ntawm cov yam ntxwv ib puag ncig sab nraud xws li dej noo, av noo, qhov kub thiab txias hloov pauv, thiab ultraviolet hluav taws xob. Cov txheej txheem khov kho no ua haujlwm ua lub rwb thaiv hluav taws xob, tiv thaiv kev poob siab hluav taws xob thiab cov hluav taws xob xau. Cov ntaub ntawv hnub ci feem ntau yog ua los ntawm cov khoom sib xyaw polymer, feem ntau muaj ntau txheej kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws.
Cov yam ntxwv ntawm lub hnub ci vaj huam sib luag:
1. Tiv taus huab cua: Cov ntaub thaiv hnub ci tau tsim los kom tiv taus huab cua hnyav, suav nrog nag, cua daj cua dub, daus thiab cua hlob. Lawv tau tsim los muab kev tiv thaiv mus sij hawm ntev tiv thaiv cov dej noo nkag, kom ntseeg tau tias cov hlwb photovoltaic tseem zoo thiab ua haujlwm tau zoo.
2. Kev ruaj khov ntawm UV: Lub hom phiaj tseem ceeb ntawm lub hnub ci backsheet yog los tiv thaiv cov cell photovoltaic los ntawm cov teeb meem UV. Nws ua haujlwm ua tus stabilizer UV, txo qis kev puas tsuaj ntawm cell dhau sijhawm. Qhov feature no ua rau lub vaj huam sib luag ntev dua thiab pab tswj nws txoj kev ua haujlwm thoob plaws nws lub neej.
3. Kev rwb thaiv hluav taws xob: Ua ib qho tseem ceeb ntawm kev nyab xeeb, lub hnub ci backplane muaj kev rwb thaiv hluav taws xob siab. Cov txheej rwb thaiv no tiv thaiv kev poob siab hluav taws xob, tshem tawm cov dej ntws tawm, thiab tiv thaiv kev phom sij hluav taws, ua kom muaj kev nyab xeeb tag nrho ntawm lub hnub ci vaj huam sib luag.
4. Kev ua kom sov tau zoo: Lub hnub ci backsheet yog tsim los kom cua sov tawm tau zoo. Los ntawm kev txo qhov kub ntawm cov photovoltaic cells, lub hnub ci backsheet pab tswj kom muaj kev hloov pauv hluav taws xob zoo dua txawm tias thaum raug tshav ntuj ntev.
Daim ntawv thov ntawm lub hnub ci backplane:
1. Cov chaw tsim hluav taws xob hnub ci rau cov chaw siv: Cov thev naus laus zis hnub ci backplane siv dav hauv cov chaw tsim hluav taws xob hnub ci loj vim nws muaj peev xwm tiv taus cov xwm txheej ib puag ncig hnyav. Lawv qhov ruaj khov thiab kev ntseeg tau ua rau lawv yog cov khoom tseem ceeb hauv cov chaw tsim hluav taws xob hnub ci rau cov chaw siv uas qhov kev ua haujlwm ntev yog qhov tseem ceeb.
2. Cov tshuab hnub ci hauv tsev: Cov thev naus laus zis hnub ci backplane kuj tseem ceeb rau kev teeb tsa hnub ci hauv tsev. Los ntawm kev tiv thaiv cov hlwb photovoltaic los ntawm cov khoom sab nraud, cov ntawv hnub ci backsheets ua kom muaj zog zoo tshaj plaws, ua rau tus tswv tsev rov qab tau nyiaj ntau dua. Tsis tas li ntawd, cov khoom rwb thaiv tsev zoo heev pab txhawb kev nyab xeeb ntawm cov tshuab hluav taws xob hnub ci hauv tsev.
3. Cov Haujlwm Hnub Ci Rau Kev Lag Luam thiab Kev Lag Luam: Txij li cov tsev rau khoom mus rau cov chaw tsim khoom thiab cov tsev ua haujlwm, cov tsev lag luam thiab kev lag luam tuaj yeem tau txais txiaj ntsig zoo los ntawm kev teeb tsa cov vaj huam sib luag hnub ci. Cov thev naus laus zis hnub ci ntxiv ib txheej ntxiv ntawm kev tiv thaiv uas tswj kev ua haujlwm ntawm cov vaj huam sib luag thiab txuas lawv lub neej ntev hauv qhov chaw nyuaj.
xaus lus:
Daim ntawv qhia hnub ci thev naus laus zis ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo, ruaj khov thiab kev nyab xeeb ntawm cov vaj huam sib luag hnub ci. Cov ntawv thaub qab hnub ci tau dhau los ua ib qho tseem ceeb hauv cov tshuab hluav taws xob hnub ci vim lawv tiv taus huab cua zoo heev, UV ruaj khov, rwb thaiv tsev hluav taws xob, thiab thermal conductivity. Txawm hais tias nws yog lub chaw tsim hluav taws xob hnub ci lossis chaw teeb tsa hauv tsev, cov vaj huam sib luag hnub ci pab ua kom zoo dua qub thiab txo qhov yuav tsum tau saib xyuas. Raws li kev lag luam hnub ci txuas ntxiv mus, kev nce qib hauv thev naus laus zis hnub ci backsheet yuav ua rau muaj kev ua haujlwm siab dua thiab lub neej ntev dua ntawm cov tshuab hnub ci.
