Solar Back Sheet Chaw tsim tshuaj paus nyob rau hauv Suav teb rau hnub ci Pv Modules
Kev piav qhia
Hnub Ci Tsiaj Backsheet yog ib qho tseem ceeb ntawm cov ntaub ntawv encapsulation uas yog siv nyob rau hauv PV module, muaj li ntawm cov fluorine cov ntaub ntawv uas zoo heev huab cua durability thiab PET nrog zoo heev hluav taws xob rwb thaiv tsev.
Hnub ci module rov qab daim ntawv feem ntau muaj ob pawg: fluorine-muaj thiab tsis muaj fluorine.Cov ntawv rov qab uas muaj fluorine muaj xws li ob sab fluorine-muaj (xws li TPT) thiab ib sab fluorine-muaj (xws li TPE);thaum tsis muaj fluorine-muaj cov ntaub ntawv rov qab yog laminated los ntawm multilayers ntawm PET los ntawm cov nplaum.
PV cov khoom siv dav siv hauv ntau qhov kev lag luam vim nws lub zog txuag, ib puag ncig tus phooj ywg thiab lub neej ntev.Daim ntawv rov qab yog qhov tseem ceeb los xyuas kom meej tias nws muaj ntau tshaj 25 xyoo ua haujlwm-lub neej.Lub hnub ci module rov qab daim ntawv yog nyob rau saum npoo ntawm PV module.Tom qab kev sib raug zoo nrog EVA, nws tuaj yeem thaiv huab cua los ua lub tshuab nqus tsev vacuum rau thaj tsam tseem ceeb ntawm lub module.Txhawm rau kom ntseeg tau tias, lub luag haujlwm tseem ceeb ntawm lub foob yog ua kom dej-pov thawj, huab cua-pov thawj thiab hluav taws xob-pov thawj.Yog li lub hnub ci module rov qab yuav tsum muaj hluav taws xob rwb thaiv tsev siab, huab cua tsis kam, siab adhesion thiab dej vapor permeability tsawg.
Tsiaj rov qab daim ntawv nrog kev ua tau zoo heev rau hnub ci vaj huam sib luag.Piv txwv li: huab cua Resistance Backsheet.Zoo tag nrho lub cev kev ua tau zoo, dej, oxygen thaiv kev ua tau zoo, dielectric huab cua aging kuj.Haum rau txhua yam txheej txheem laminating.Nws tuaj yeem ua rau lub hnub ci vaj huam sib luag siv ntau tshaj 25 xyoo hauv pem teb, ru tsev, gobi, suab puam, ntug hiav txwv.

Daim ntawv thov zoo ntawm Tsiaj rov qab daim ntawv rau txawv me me hnub ci vaj huam sib luag.
1. Huab cua tiv taus
Los ntawm kev ntsuam xyuas kev laus ob zaug ntawm 85 khub ntawm 1000 teev, yuav muaj kev tsis sib haum xeeb, tsis tawg, tsis ua npuas.Yuav tsis muaj xim daj tsis muaj embrittlement tom qab kev laus los ntawm kev siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob (QUVB) kuaj 3000 teev.
2. Kev ruaj ntseg siab
Qib kev ruaj ntseg tau dhau cov nplaim hluav taws-retardant UL 94-V2 nplaim hluav taws-retardant qib, UL nplaim taws kis tau qis dua 100, uas zoo lav cov qauv kev ruaj ntseg.
3.High rwb thaiv tsev
TUV Rhineland ntawm PD≥1000VDC tuaj yeem zam qhov hluav taws xob arcing module.
4.High Dej Vapor Resistance
Los ntawm infrared dej vapor permeability tester, dej vapor permeability tus nqi ≤1.0g / m2.d.
5.High Adhesion
Tom qab kev kho mob nano-plasma, lub zog saum npoo ntawm cov tshuaj fluoride siab tuaj yeem kav ntev li 45mN / m lossis ntau dua li ntawm rau lub hlis.
6.High-end Match
Haum rau loj-scale photovoltaic fais fab nroj tsuag nrog crystalline silicon cell module pob.
7.High Compatibility
Kev sib raug zoo zoo los ntawm kev sib txuas nrog lwm cov ntaub ntawv ntim ntawm module.
8. Kev ua haujlwm siab
Rau nws ob-sided adhesion, tsis tas yuav paub qhov txawv ntawm daim ntawv rov qab qhov zoo thiab qhov tsis zoo thaum cov khoom ntim khoom, uas coj kev yooj yim rau cov kws tshaj lij.
9.High Flexibility
Cov ntaub ntawv nplaum ntawm cov pob txha ntim rau pob rau lub module thiab EVA tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
