Famba mune chero fekitori ye solar panel. Laminator iri kushanda pa150 ° C, ichidzvanya EVA encapsulant pakati pegirazi nebacksheet. Pasina tepi yePTFE, EVA yakanyungudutswa yaizonyungudika paplaten yekudziya uye silicone diaphragm, ichigadzira tsvina inonamira inoparadza pani rinotevera uye inotora maawa kuti iparare.
Ndiko kushandiswa kuri pachena. Asi pane isinganyanye kuoneka: mukati meiyo yapera module, PTFE tepi
Aokai PTFE inopa marudzi ese ari maviri - magadzirirwo ekushandisa uye yekuvharisa zvachose - ine zvakasiyana zvakasiyana zvinodiwa. Ngatifambei nepapi panopinda tepi yePTFE muPV module, uye zvimiro zvipi zvine basa panzvimbo yega yega.

Laminator Edge Dziviriro - Kurwisa EVA Kunamira
Munguva yelamination (145-165 ° C, 15-25 maminitsi), iyo EVA encapsulant inonyunguduka uye inoyerera. Zvimwe zvinongosvina kumacheto. Kana ikabata simbi yekudziya ndiro kana iyo silicone vacuum diaphragm, inosungirirana zvachose.
Iyo PTFE tepi inogadzirisa sei
PTFE tepi inoiswa kune idzi nzvimbo inoita kuti EVA arapwe kubva muchidimbu chimwe. Vashandi vanopukuta tepi nemucheka pakati pemapurogiramu, uye kushandiswa kumwe chete kunotora mavhiki.
Chii chekutarisa mune lamination tepi
Substrate: Fiberglass-yakasimbiswa PTFE (0.13-0.18mm). Yakachena PTFE bhaisikopo rinobvarura zviri nyore kana uchiraura akarapwa EVA.
Adhesive: Silicone PSA chete. Acrylic inopfava uye inoyerera pa150 ° C, ichisvibisa laminator.
Heat shrinkage: Haina basa pakupisa tembiricha - tepi haifanirwe kupeta kana kuburitsa simbi mipendero.
Low outgassing: Pasi pevacuum lamination, volatiles kubva kune yakashata-mhando yekunamira inogona kukonzera mabhuru mumodule. Kurasikirwa kwehuwandu hwehuwandu <1% ndiyo chinangwa chakanaka.
Kubva pafekitari pasi : Mumwe mugadziri wemodule akashuma kuderedza laminator yekuchenesa nguva kubva pamaminitsi makumi mana nemashanu pakuchinja kusvika kumaminitsi mashanu mushure mekuchinja kune premium fiberglass-backed PTFE tepi ine high-crosslink silicone adhesive. Iyo tepi inodhura zvakanyanya kumberi asi yakazvibhadhara mumavhiki maviri.
Permanent Busbar Insulation - 25-Year Kuvimbika Kunodiwa
Mukati memodhi yakapedzwa, mabhasi (tinned copper ribbon) anobatanidza tambo dzesero kune junction box. Pavanopfuura nepaburi rekumashure, kana kukotama padyo nealuminium furemu, iyo insulation clearance inogona kusimba. PTFE tepi inoputira yakatenderedza bhazi panzvimbo idzi.
Tepi iyi haibatike . Inofanira kupedza hupenyu hwewaranti yemodule - makore makumi maviri neshanu kana kupfuura - kunze, pasi peUV, tembiricha yebhasikoro (-40 ° C kusvika +85 ° C), uye kupisa kwakanyorova (85 ° C / 85% RH).

Silicone PSA, kwete acrylic
Acrylic hydrolyzes pasi pekupisa kwakanyorova, kurasikirwa nekunamatira uye kubuda kweacetic acid.
UL94 V-0 kana VTM-0
Inodiwa kuchengetedza chitupa (UL 510)
Indasitiri chinyorwa: Vamwe vagadziri vemodule vanodhura vanoshandisa polyimide (Kapton) tepi yekuvhara bhasi. Nepo polyimide ine simba repamusoro dielectric, inotora hunyoro uye inogona kurasikirwa nemidziyo yekuisa mukati mukupisa kwakanyorova. PTFE inoramba yakagadzikana. Kune 1500V modules, PTFE iri kuwedzera kutaurwa.
Junction Bhokisi Fixation & Insulation
Mukati mebhokisi rekusangana, miswe yebhasibar inotengeswa kune diode / terminal block. PTFE tepi inoshandisa mabasa maviri: insulation apo ma conductor asina chinhu ari padyo, uye mechanic fixation - kurovera waya pasi kunodzivirira kuneta kwekudengenyeka.
Sei murazvo retadancy inosungirwa
Iyo junction bhokisi inogona kudzima sosi kana iyo bypass diode ikatadza kupfupika. PTFE tepi pano inofanira kuva nechiyero cheUL94 V-0. Uyewo, inofanira kubata kupisa kunoramba kuripo kubva ku diode (kazhinji 85-90 ° C) pasina zvinokambaira kana kurasikirwa nekunamatira.
Yakaonda PTFE firimu tepi (0.05-0.08mm) inoshanda zvakanaka pano nekuti inoputira zvakasimba kutenderera waya nematerminal.
Soldering Mask & Yenguva Dziviriro
Panguva yekubata uye tambo, flux uye yakanyungudutswa solder inogona kupfachukira pamaseru, zvichikonzera kuremara kwekuzora kana micro-cracks. PTFE tepi inovhara kwechinguva maseru edge kana nzvimbo dzisiri dzekutengesa.
Zvinodiwa zvakasiyana - hapana kuchembera kwenguva refu kunodiwa
Kungopikisa kupisa kwakanyanya (kuratidzwa kwenguva pfupi kusvika 300 ° C+ kubva pane inotengeswa iron), inodzivirira-inodzivirira nzvimbo, uye zero zvakasara mushure mekusvuura. Kunyangwe acrylic anonamira anogona kushanda pano sezvo kuratidzwa kuri kupfupi uye tembiricha yakakwira - asi silicone inochengetedzeka kune chero kupisa kunopfuura 200 ° C.

Final Takeaways
Maviri akasiyana ePTFE tepi mapoka anoshandira iyo PV indasitiri.
Maitiro ekushandisa (laminator kuchengetedza, soldering mask): tarisa pane isiri-tsvimbo, kuchenesa nyore, uye kwenguva pfupi kupisa kupisa.
Permanent yemukati insulation (busbar kuputira, junction box): inoda yakazara IEC 61215 qualification - yakanyorova kupisa, thermal cycling, UV, uye shrinkage <1%.
Silicone PSA haigone kutaurirana kune chero tepi ichaona 150 ° C + kana 25-gore rekunze hupenyu.
