Yendani mu fakitale iliyonse ya solar panel. Laminator ikuyenda pa 150 ° C, kukanikiza EVA encapsulant pakati pa galasi ndi backsheet. Popanda tepi ya PTFE, EVA yosungunuka imatha kugwera pa mbale yotenthetsera ndi silikoni diaphragm, ndikupanga chisokonezo chomwe chimawononga gulu lotsatira ndikuchotsa maola ambiri.
Ndiko kugwiritsa ntchito koonekeratu. Koma pali yocheperako: mkati mwa gawo lomalizidwa,Tepi ya PTFE imakulunga m'mabasi momwe amadutsa potsegula kumbuyo, kuteteza kuphulika kwamphamvu kwamagetsi. Kwa machitidwe a 1500V (muyezo lero), kutchinjiriza uku ndikoyenera kutetezedwa.
Aokai PTFE imapereka mitundu yonse iwiri - zogwiritsiridwa ntchito ndi kutsekereza kosatha - zokhala ndi zofunikira zosiyana kwambiri. Tiyeni tidutse pomwe tepi ya PTFE imalowa mu gawo la PV, ndi zomwe zili zofunika pagawo lililonse.
Kumene PTFE Tepi Imagwiritsidwa Ntchito Popanga Solar Module Production
Palibe ntchito imodzi - zisanu.

Kutentha kwa kutentha: Kusawoneka pa kutentha kwa lamination - tepi sayenera kupindika kapena kuonetsa m'mphepete mwachitsulo.
Kutsika kwapang'onopang'ono: Pansi pa vacuum lamination, ma volatiles ochokera ku zomatira zabwinobwino amatha kuyambitsa thovu mu module. Kutayika kwathunthu <1% ndi chandamale chabwino.
Kuchokera kufakitale : Wopanga ma module m'modzi adanenanso kuti akuchepetsa nthawi yoyeretsa laminator kuchoka pa mphindi 45 pakusintha kupita ku mphindi 5 mutasinthira tepi ya PTFE yokhala ndi zomatira za silicone yapamwamba kwambiri. Tepiyo idakwera mtengo kwambiri koma idadzilipira yokha pakatha milungu iwiri.
Mkati mwa gawo lomalizidwa, mabasi (riboni yamkuwa) amalumikiza zingwe zama cell ku bokosi lolumikizirana. Kumene amadutsa pong'ambika kumbuyo, kapena kupindika pafupi ndi chimango cha aluminiyamu, chilolezo cha insulation chikhoza kukhala cholimba. Tepi ya PTFE imazungulira pa basi pazigawo izi.
Tepi iyi si yodyedwa . Iyenera kukhala moyo wa chitsimikizo cha gawoli - zaka 25 kapena kuposerapo - panja, pansi pa UV, kutentha kwa njinga (-40 ° C mpaka +85 ° C), ndi kutentha kwachinyezi (85 ° C / 85% RH).
Zofunikira kwambiri za tepi yotsekera mabasi
Chofunikira
Chifukwa Chake Kuli Kofunika?
Mphamvu ya dielectric ≥8kV (0.08mm) / ≥10kV (0.13mm)
Ayenera kukhala okwera pambuyo pa kukalamba kwa kutentha kwa 1000-2000h (IEC 61215)
Kuchepa konse ≤1% (chabwino ≤0.5%)
Imaletsa kupsinjika kwa backsheet kapena mabasi owonekera pambuyo pa matenthedwe
CTI 600V (PTFE Natural)
Palibe ma conductive carbon tracks pansi pa kuipitsidwa pamwamba
Kukana kwa UV (kwa ma module agalasi awiri)
Zomatira siziyenera kunyonyotsoka pakulowa kwa kuwala
Silicone PSA, osati acrylic
Acrylic hydrolyzes pansi pa kutentha konyowa, kutaya kumamatira ndi kutuluka kwa asidi acetic
UL94 V-0 kapena VTM-0
Zofunikira pachitetezo chachitetezo (UL 510)
Chidziwitso chamakampani: Ena opanga ma module otsika mtengo amagwiritsa ntchito tepi ya polyimide (Kapton) potsekereza mabasi. Ngakhale polyimide ili ndi mphamvu zochulukirapo za dielectric, imayamwa chinyezi ndipo imatha kutaya mphamvu zotsekera pakatentha konyowa. PTFE imakhalabe yokhazikika. Kwa ma module a 1500V, PTFE ikuchulukirachulukira.
Junction Box Fixation & Insulation
Mkati mwa bokosi lolumikizirana, michira ya busbar imagulitsidwa ku diode / terminal block. Tepi ya PTFE imagwira ntchito ziwiri: kutsekereza komwe ma conductor opanda kanthu ali pafupi, ndi kukonza makina - kutsitsa mawaya pansi kumateteza kutopa kwa vibration.
Chifukwa chiyani kuchepa kwamoto ndikofunikira
Bokosi lolumikizirana ndi gwero lomwe lingathe kuyatsa ngati ma bypass diode alephera. Tepi ya PTFE apa ikuyenera kukhala ndi mavoti a UL94 V-0. Komanso, iyenera kupirira kutentha kosalekeza kuchokera ku diode (nthawi zambiri 85-90 ° C) popanda zokwawa kapena kutaya zomatira.
Tepi yopyapyala ya filimu ya PTFE (0.05-0.08mm) imagwira ntchito bwino pano chifukwa imakulunga mozungulira mawaya ndi ma terminals.
Soldering Mask & Chitetezo Chakanthawi
Pakumanga ndi zingwe, flux ndi solder yosungunuka imatha kufalikira pama cell, kupangitsa zolakwika zodzikongoletsera kapena ming'alu yaying'ono. Tepi ya PTFE imaphimba kwakanthawi m'mphepete mwa cell kapena madera osagulitsa.
Magawo awiri osiyana kwambiri a matepi a PTFE amatumikira makampani a PV.
Zomwe zimagwiritsidwa ntchito panjira (chitetezo cha laminator, chigoba cha soldering): yang'anani kwambiri pa kusamata, kuyeretsa kosavuta, komanso kukana kutentha kwakanthawi.
Kutchinjiriza kosatha mkati (kukulunga kwa mabasi, bokosi lolumikizira): funani kuyenerera kwathunthu kwa IEC 61215 - kutentha konyowa, kupalasa njinga, UV, ndi kuchepa <1%.
Silicone PSA ndi yosakanizidwa pa tepi iliyonse yomwe iwona 150 ° C + kapena moyo wakunja wazaka 25.
Aokai PTFE imapereka magulu onse awiri zolemba zoyeserera. Pakutchinjiriza kwa mabasi, timapereka data yonyezimira yamphamvu ya dielectric yanthawi yayitali. Kwa tepi ya lamination, timapereka kusanthula kwa outgassing ndi maumboni a moyo wamunda.
Kuti mudziwe zambiri, mapulani ogwiritsira ntchito, ndi zothetsera makonda pazogulitsa zonse kuphatikizapo PTFE nsalu yotentha kwambiri, tepi yomatira yotentha kwambiri ya PTFE, lamba wa PTFE mesh conveyor lamba, lamba wa makina osakanikirana, mbali imodzi ya PTFE yokutidwa nsalu, lamba wonyamula kutentha wotentha kwambiri ndi nsalu ya fiberglass :
