Hamba uye kunoma iyiphi imboni yamaphaneli elanga. I-laminator isebenza ku-150°C, icindezela i-EVA encapsulant phakathi kwengilazi ne-backsheet. Ngaphandle kwetheyiphu ye-PTFE, i-EVA encibilikisiwe izogeleza ku-heater platen kanye ne-silicone diaphragm, idale ukungcola okunamathelayo okucekela phansi iphaneli elandelayo futhi kuthathe amahora ukusula.
Yilokho ukusetshenziswa okusobala. Kepha kukhona ebonakala kancane: ngaphakathi kwemojuli eqediwe, Itheyiphu ye-PTFE isonga ezindongeni zebhasi lapho idlula khona ekuvulekeni kwamakhasi angemuva, ivimbela ukuqhekeka kwe-voltage ephezulu. Kuzinhlelo ze-1500V (ezijwayelekile namuhla), lokhu kugqumisa kuwukuphepha okufanele.
I-Aokai PTFE inikezela ngezinhlobo zombili - izinto ezisetshenziswayo zenqubo kanye nokwahlukanisa unomphela - okunezidingo ezihluke ngokuhlukile. Ake sidlule lapho i-PTFE tape ingena khona kumojuli ye-PV, futhi yiziphi izakhiwo ezibalulekile endaweni ngayinye.
Lapho I-PTFE Tape Isetshenziswa Ekukhiqizeni Kwemojula Yelanga

I-Laminator Edge Protection - Ukulwa nokunamathela kwe-EVA
Ngesikhathi se-lamination (145-165 ° C, 15-25 imizuzu), i-EVA encapsulant iyancibilika futhi igeleze. Abanye ngokungenakugwemeka baphume baye emaphethelweni. Uma ithinta ipuleti lokushisisa lensimbi noma i-silicone vacuum diaphragm, ibopha unomphela.
Indlela i-PTFE tape iyixazulula ngayo
Itheyiphu ye-PTFE esetshenziswa kulezi zindawo yenza i-EVA ephulukisiwe ixebuke esiqeshini esisodwa. Ama-operators asula i-tape ngendwangu phakathi kwemijikelezo, futhi isicelo esisodwa sithatha amasonto.
Yini okufanele uyibheke ku-lamination tape
I-Substrate: I -Fiberglass-reinforced PTFE (0.13-0.18mm). Ifilimu ye-PTFE ehlanzekile ikhala kalula uma isula i-EVA eselashiwe.
I-Adhesive: I-Silicone PSA kuphela. I-Acrylic iyathamba futhi iwele ku-150°C, ingcolise i-laminator.
Ukuncipha kokushisa: Ayinakwa lapho izinga lokushisa lancibilikayo - itheyiphu akufanele isonge noma iveze imiphetho yensimbi.
Ukukhipha umoya okuphansi: Ngaphansi kwe-vacuum lamination, ukuguquguquka okuvela kokunamathelayo kwekhwalithi embi kungabangela amabhamuza kumojula. Ingqikithi yokulahlekelwa kwesisindo <1% iyithagethi enhle.
Kusukela esitezi sefekthri : Umenzi wemojula oyedwa ubike ukuthi wehlisa isikhathi sokuphumula sokuhlanza i-laminator ukusuka kumaminithi angu-45 ngokushintshana ukuya kumaminithi angu-5 ngemva kokushintshela kutheyipu ye-PTFE esekelwe i-fiberglass ye-premium ene-high-crosslink silicone adhesive. Itheyiphu ibize kakhulu kusenesikhathi kodwa izikhokhele yona emasontweni amabili.
I-Permanent Busbar Insulation - Kudingeka Ukwethembeka Kweminyaka engama-25
Ngaphakathi kwemojuli eqediwe, amabhasi (iribhoni yethusi ethini) ixhuma izintambo zeseli ebhokisini lokuhlangana. Lapho bedlula khona esikhaleni seshidi elingemuva, noma begoba eduze kohlaka lwe-aluminium, imvume yokufakwa kwe-insulation ingaba nzima. Itheyiphu ye-PTFE isonga ibha yebhasi kulawa maphuzu.
Le tape ayidleki . Kufanele ihlale impilo yewaranti yemojuli - iminyaka engu-25 noma ngaphezulu - ngaphandle, ngaphansi kwe-UV, izinga lokushisa lokuhamba ngebhayisikili (-40°C kuya ku-+85°C), nokushisa okumanzi (85°C/85% RH).
Ukucaciswa okubalulekile kwetheyiphu yokufakwa kwe-busbar
Imfuneko |
Kungani Kubalulekile? |
Amandla e-Dielectric ≥8kV (0.08mm) / ≥10kV (0.13mm) |
Kumelwe ihlale iphakeme ngemva kokuguga kokushisa okumanzi okungu-1000-2000h (IEC 61215) |
Ukuncipha okuphelele ≤1% (okungcono ≤0.5%) |
Ivimbela ingcindezi ye-backsheet noma ibha yebhasi eveziwe ngemva kwemijikelezo yokushisa |
I-CTI 600V (PTFE yemvelo) |
Awekho amathrekhi e-carbon conductive ngaphansi kokungcoliswa kwendawo |
Ukumelana ne-UV (kumamojula engilazi ephindwe kabili) |
Okunamathelayo akumele kwehlise izinga ekungeneni kokukhanya onqenqemeni |
I-Silicone PSA, hhayi i-acrylic |
I-Acrylic hydrolyzes ngaphansi kokushisa okumanzi, ilahlekelwa ukunamathela kanye ne-acetic acid ephuma ngaphandle |
I-UL94 V-0 noma i-VTM-0 |
Iyadingeka ukuze uthole isitifiketi sokuphepha (UL 510) |
Inothi lemboni: Abanye abenzi bamamojula angabizi kakhulu basebenzisa itheyiphu ye-polyimide (Kapton) ukuze bavale ibhasbar. Nakuba i-polyimide inamandla aphakeme e-dielectric, imunca umswakama futhi ingalahlekelwa izici zokushisa lapho kushisa okumanzi. I-PTFE ihlala izinzile. Kumamojula angu-1500V, i-PTFE iya ngokuya icaciswa.
I-Junction Box Fixation & Insulation
Ngaphakathi kwebhokisi lokuhlangana, i-busbar tails solder to the diode/terminal block. Itheyiphu ye-PTFE isebenzisa izindima ezimbili: ukwahlukanisa lapho amakhondaktha angenalutho aseduze, kanye nokulungiswa komshini - izintambo zokuthinta phansi kuvimbela ukukhathala kokudlidliza.
Kungani ukuncipha komlilo kuyimpoqo
Ibhokisi lokuhlangana liwumthombo ongaba khona wokuthungela uma i-bypass diode ihluleka. Itheyiphu ye-PTFE lapha kufanele ibe nesilinganiso esingu-UL94 V-0. Futhi, kufanele iphathe ukushisa okuqhubekayo okuvela ku-diode (imvamisa engu-85-90 ° C) ngaphandle kokunwabuzelayo noma ukulahlekelwa ukunamathela.
Itheyiphu yefilimu ye-PTFE ezacile (0.05-0.08mm) isebenza kahle lapha ngoba isonga ngokuqinile ezintamboni nasezintanjeni.
I-Soldering Mask nokuvikelwa Kwesikhashana
Ngesikhathi sokuqopha nokufaka izintambo, i-flux ne-solder encibilikisiwe ingasakazeka kumaseli, ibangele ukukhubazeka kwezimonyo noma imifantu emincane. Itheyiphu ye-PTFE imboza okwesikhashana imiphetho yeseli noma izindawo ezingadayisi.
Izidingo ezihlukene - akukho ukuguga kwesikhathi eside okudingekayo
Ukumelana nokushisa okuphezulu (ukuchayeka kafushane ku-300°C+ kusuka ku-solder iron), indawo exosha i-solder, nezinsalela eziyiziro ngemva kokuxebuka. Ngisho ne-adhesive ye-acrylic ingasebenza lapha njengoba ukuchayeka kukufushane futhi amazinga okushisa aphezulu - kodwa i-silicone iphephile kunoma yikuphi ukushisa okungaphezu kuka-200°C.

Okokugcina Okuthathayo
Izigaba ezimbili zamateyipu ze-PTFE ezihluke kakhulu zisebenzela imboni ye-PV.
Izinto ezisetshenziswayo zenqubo (ukuvikelwa kwe-laminator, imaski e-soldering): gxila ekungagxili, ukuhlanza okulula, nokumelana nokushisa kwesikhashana.
Ukufakwa kwangaphakathi okuhlala njalo (ukugoqa ibhasbar, ibhokisi lokuhlangana): funa ukufaneleka okugcwele kwe-IEC 61215 - ukushisa okuswakama, ukuhamba ngebhayisikili elishisayo, i-UV, kanye nokuncipha kuka-<1%.
I-Silicone PSA akuxoxiswana ngayo kunoma iyiphi itheyiphu ezobona u-150°C+ noma impilo yangaphandle yeminyaka engu-25.
I-Aokai PTFE inikeza zombili izigaba ngemibhalo yokuhlola. Ngokufakwa kwe-busbar, sihlinzeka ngedatha yamandla e-dielectric yokushisa okumanzi. Ukuze uthole i-lamination tape, sinikeza ukuhlaziywa kwe-outgassing kanye nezinkomba zempilo yasensimini.
Okuqukethwe okungenhla kwezobuchwepheshe kunikezwa ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.
Ukuze uthole imininingwane eningiliziwe, izinhlelo zohlelo lokusebenza, nezixazululo ezenziwe ngokwezifiso zemikhiqizo yobubanzi obugcwele okuhlanganisa i-PTFE indwangu yokushisa ephezulu, i-PTFE itheyipu enamathelayo, ibhande le-PTFE mesh conveyor, ibhande lomshini wokuhlanganisa elingenamthungo, indwangu eboshwe ye-PTFE yohlangothi olulodwa, ibhande lokuhambisa elimelana nokushisa okuphezulu nendwangu ye-fiberglass :
Ukugcina ubungcweti nobuqotho, sihlinzeka ngezixazululo zezimboni ezingokwezifiso zokuma okukodwa kanye nesevisi eqaphelayo yangemva kokuthengisa.
