PTFE Tape mu kukola PV: Okuva ku Lamination Consumable okutuuka ku Insulation ey’emyaka 25

Tambula mu kkolero lyonna ery’amasannyalaze g’enjuba. Laminator ekola ku 150°C, ng’enyiga EVA encapsulant wakati w’endabirwamu ne backsheet. Awatali PTFE tape, EVA eyasaanuuse yandikulukuta ku heating platen ne silicone diaphragm, n’ekola ekivundu ekikwatagana ekiyonoona ekipande ekiddako era kitwala essaawa eziwera okusekula.

Oyo y'enkozesa eyeeyolese. Naye waliwo ekitalabika nnyo: munda mu modulo ewedde, . Tape ya PTFE ezinga ku busbars we ziyita mu bifo ebiggulwawo backsheet, ekiziyiza okuwuguka kwa vvulovumenti eya waggulu. Ku nkola za 1500V (eza mutindo leero), insulation eno ya safety must.

Aokai PTFE egaba ebika byombi – ebikozesebwa mu nkola n’okuziyiza okw’olubeerera – n’ebyetaago eby’enjawulo ennyo. Ka tutambule mu kifo PTFE tape gy’egenda mu modulo ya PV, era eby’obugagga ki ebikulu ku buli kifo.

Awali PTFE Tape Ekozesebwa mu Solar Module Production

Tewali kusaba kumu – kutaano.

Laminator Edge Protection – Okulwanyisa EVA Stikiness

Mu kiseera ky’okusiba (145-165°C, eddakiika 15-25), ekirungo kya EVA kisaanuuka ne kikulukuta. Ebimu tekyewalika bisika okutuuka ku mbiriizi. Singa ekwatagana n’ekyuma ekibugumya oba silicone vacuum diaphragm, ekwatagana enkalakkalira.

1. Engeri PTFE tape gy'egigonjoola

PTFE tape esiigibwa ku bintu bino efuula EVA ewonye okusekula mu kitundu kimu. Abaddukanya olutambi basiimuula olugoye wakati w’enzirukanya, era okusiiga omulundi gumu kumala wiiki eziwera.

2. By’olina okunoonya mu lamination tape

• Substrate: PTFE enyweza fiberglass (0.13-0.18mm). Pure PTFE film amaziga mangu nnyo nga scraping off cured EVA.

• Ekisiiga: Silicone PSA yokka. Acrylic egonvuwa n’ekulukuta ku 150°C, n’efuula laminator obucaafu.

• Okukendeera kw’ebbugumu: Tekifaayo ku bbugumu lya lamination – tape terina kuzingulula oba okulaga empenda z’ebyuma.

• Low outgassing: Wansi wa vacuum lamination, ebiwunya okuva mu adhesive ey’omutindo omubi bisobola okuleeta bubbles mu module. Okufiirwa kw’amasasi kwonna <1% kiruubirirwa kirungi.

Okuva wansi mu kkolero : Omukozi wa modulo omu yategeeza nti yakendeeza ku budde bw’okuyonja laminator okuva ku ddakiika 45 buli ssifiiti okutuuka ku ddakiika 5 oluvannyuma lw’okukyusa okudda ku ttaapu ya PTFE ey’omutindo ogwa waggulu eriko fiberglass-backed nga eriko high-crosslink silicone adhesive. Akatambi kano kaali kagula ssente nnyingi mu maaso kyokka ne yeesasula mu wiiki bbiri.

Busbar Insulation ey’olubeerera – Okwesigamizibwa okw’emyaka 25 kwetaagisa

Munda mu modulo ewedde, busbars (tinned copper ribbon) zigatta emiguwa gy’obutoffaali ku junction box. We ziyita mu slit mu backsheet, oba okufukamira okumpi ne aluminium frame, insulation clearance eyinza okuba nga nnywevu. PTFE tape ezinga busbar mu bifo bino.

Akatambi kano si kakozesebwa . Lirina okuwangaala obulamu bwa ggaranti ya modulo – emyaka 25 oba okusingawo – ebweru, wansi wa UV, enzirukanya y’ebbugumu (-40°C okutuuka ku +85°C), n’ebbugumu ery’obunnyogovu (85°C/85% RH).

1. Ebikulu ebikwata ku busbar insulation tape

Ekiwandiiko ky’amakolero: Abamu ku bakola modulo ez’ebbeeyi entono bakozesa ttaapu ya polyimide (Kapton) okuziyiza bbaasi. Wadde nga polyimide erina amaanyi ga dielectric agasingako, anywa obunnyogovu era asobola okufiirwa eby’obugagga by’okuziyiza mu bbugumu ennyogovu. PTFE esigala nga nnywevu. Ku modulo za 1500V, PTFE yeeyongera okulambikibwa.

Junction Box Okunyweza & Okuziyiza

Munda mu junction box, emikira gya busbar gisolder ku diode/terminal block. PTFE tape ekola emirimu ebiri: insulation nga bare conductors bali kumpi, n’okunyweza ebyuma – okusiba waya wansi kiziyiza okukoowa okukankana.

Lwaki okuziyiza ennimi z’omuliro kikakatako

Ekibokisi ky’okuyunga (junction box) ye nsibuko y’omuliro (potential ignition source) singa bypass diode eremererwa mu bumpimpi. PTFE tape wano erina okuba n'ekipimo kya UL94 V-0. Era, erina okukwata ebbugumu eritasalako okuva mu dayodi (mu ngeri entuufu 85-90°C) nga tekyekulukuunya oba okufiirwa okunywerera.

Thin PTFE film tape (0.05-0.08mm) ekola bulungi wano kubanga ezinga bulungi ku waya ne terminals.

Soldering Mask & Obukuumi obw'ekiseera

Mu kiseera ky’okukuba tabbing n’okusiba emiguwa, flux ne molten solder bisobola okumansira ku butoffaali, ne bivaako obuzibu mu kwewunda oba micro-cracks. PTFE tape ebikka okumala akaseera ku mbiriizi z’obutoffaali oba ebifo ebitali bya kusoda.

Ebyetaago eby’enjawulo – tekyetaagisa kukaddiwa kwa bbanga ddene

Just high heat resistance (okumala akaseera katono ku 300°C+ okuva mu soldering iron), solder-repellent surface, ne zero residue oluvannyuma lw’okusekula. Ne acrylic adhesive eyinza okukola wano okuva exposure bweri okumpi ate nga n’ebbugumu liri waggulu – naye silicone asinga obukuumi ku bbugumu lyonna erisukka 200°C.

Ebintu Ebisembayo Okutwala

Ebika bya PTFE tape bibiri eby’enjawulo ennyo biweereza amakolero ga PV.

• Ebintu ebikozesebwa mu nkola (okukuuma laminator, masiki ya solder): essira lisse ku bitakwata, byangu okuyonja, n’okugumira ebbugumu mu bbanga ettono.

• Enkalakkalira munda insulation (busbar wrap, junction box): obwetaavu obujjuvu IEC 61215 ebisaanyizo – ebbugumu ennyogovu, ebbugumu cycling, UV, n’okukendeera <1%.

Silicone PSA teteesebwako ku lutambi lwonna olujja okulaba 150°C+ oba obulamu obw’ebweru obw’emyaka 25.

Aokai PTFE egaba ebika byombi ebiwandiiko by’okugezesa. Ku busbar insulation, tuwa obunnyogovu ebbugumu emyaka dielectric amaanyi data. Ku lamination tape, tuwaayo outgassing okwekenneenya n'obulamu bw'omu nnimiro ebijuliziddwa.
