Tef ɗin PTFE da aka yi amfani da shi a kan waɗannan saman yana sa EVA da aka warke ya bare a yanki ɗaya. Masu aiki suna goge tef ɗin tare da zane tsakanin hawan keke, kuma aikace-aikacen guda ɗaya yana ɗaukar makonni.

2. Abin da za a nema a cikin tef ɗin lamination

• Substrate: Fiberglass-reinforced PTFE (0.13-0.18mm). Fim ɗin PTFE mai tsabta yana hawaye da sauƙi lokacin da ake goge warkewar EVA.

• Adhesive: Silicone PSA kawai. Acrylic yana tausasa kuma yana fita a 150 ° C, yana gurɓata laminator.

• Ƙunƙarar zafi: Rashin ƙarancin zafin jiki - tef ɗin kada ya karkata ko fallasa gefuna na ƙarfe.

• Ƙarƙashin fitar da iskar gas: Ƙarƙashin lamination, rashin ƙarfi daga manne mara inganci na iya haifar da kumfa a cikin tsarin. Jimlar yawan asarar <1% manufa ce mai kyau.

Tef ɗin ya fi tsada a gaba amma ya biya kansa cikin makonni biyu.

Rufin Busbar Dindindin - Ana Bukatar Dogarowar Shekaru 25

A cikin ƙaƙƙarfan tsarin, bassan bas (kwangon jan karfen tinned) suna haɗa igiyoyin salula zuwa akwatin mahadar. Inda suka wuce ta tsaga a cikin takardar baya, ko lanƙwasa kusa da firam ɗin aluminium, izinin rufewa na iya zama m. Tef ɗin PTFE yana nannade kewaye da mashin ɗin a waɗannan wuraren.

Wannan tef ɗin ba abin amfani ba ne . Dole ne ya šauki tsawon rayuwar garantin samfurin - shekaru 25 ko fiye - a waje, ƙarƙashin UV, hawan zafin jiki (-40 ° C zuwa + 85 ° C), da zafi mai zafi (85°C/85% RH).

1. Mahimman ƙayyadaddun ƙayyadaddun bayanai don kaset ɗin rufewar busbar

Bayanan masana'antu: Wasu masu kera kayayyaki masu rahusa suna amfani da tef ɗin polyimide (Kapton) don rufin busbar. Duk da yake polyimide yana da ƙarfin dielectric mafi girma, yana ɗaukar danshi kuma yana iya rasa abubuwan rufewa a cikin zafi mai zafi. PTFE ya kasance karko. Domin 1500V kayayyaki, PTFE yana ƙara ƙayyadaddun bayanai.

Gyaran Akwatin Junction & Insulation

A cikin akwatin mahaɗar, busbar ɗin yana siyar da wutsiya zuwa toshe diode/tasha. Tef ɗin PTFE yana aiki da ayyuka guda biyu: rufin inda masu jagoranci ke kusa, da gyaran injin - tapping wayoyi ƙasa yana hana gajiyawar girgiza.

Me yasa jinkirin wuta ya zama tilas

Akwatin mahaɗa shine yuwuwar tushen kunna wuta idan diode na kewayawa ya gaza gajere. Tef ɗin PTFE anan dole ne ya sami ƙimar UL94 V-0. Hakanan, dole ne ta kula da ci gaba da zafi daga diode (yawanci 85-90 ° C) ba tare da rarrafe ko rasa mannewa ba.

Tef ɗin fim ɗin PTFE na bakin ciki (0.05-0.08mm) yana aiki da kyau a nan saboda yana nannade tam a kusa da wayoyi da tashoshi.

Masks na siyarwa & Kariya na ɗan lokaci

A lokacin tabbing da kirtani, juyi da narkakken solder na iya fantsama kan sel, haifar da lahani na kwaskwarima ko ƙananan fasa. Tef ɗin PTFE na ɗan lokaci yana rufe gefuna na tantanin halitta ko wuraren da ba sa sayarwa.

Bukatu daban-daban - ba a buƙatar tsufa na dogon lokaci

Babban juriya na zafi kawai (taƙaitaccen bayyanarwa zuwa 300°C+ daga ƙarfe mai siyar da ƙarfe), saman mai hana solder, da ragowar sifili bayan kwasfa. Ko da acrylic adhesive na iya aiki a nan tunda bayyanar gajere ce kuma yanayin zafi yana da girma - amma silicone ya fi aminci ga kowane zafi sama da 200 ° C.

Karshe Takeaways

Biyu daban-daban nau'ikan tef na PTFE suna hidima ga masana'antar PV.

• Abubuwan da ake amfani da su (kariyar laminator, abin rufe fuska): mai da hankali kan rashin tsayawa, sauƙin tsaftacewa, da juriya na ɗan gajeren lokaci.

• Dindindin na ciki rufi (busbar kunsa, junction akwatin): Bukatar cikakken IEC 61215 cancantar - damp zafi, thermal keke, UV, da shrinkage <1%.

Silicone PSA ba za a iya sasantawa ba ga kowane tef ɗin da zai ga 150°C+ ko rayuwar waje na shekaru 25.
