PTFE Tape ma PV Manufacturing: Mai Lamination Consumable a hiki i 25-makahiki Insulation

E hele i loko o kekahi hale hana panel solar. Ke holo nei ka laminator ma 150 ° C, e kaomi ana i ka EVA encapsulant ma waena o ke aniani a me ka pepa hope. Me ka ʻole o ka lipine PTFE, e hoʻoheheʻe ʻia ka EVA i hoʻoheheʻe ʻia ma luna o ka pā wela a me ka diaphragm silikoni, e hana ana i kahi ʻōpala paʻa e hōʻino ai i ka ʻaoʻao aʻe a lawe i nā hola e ʻoki ai.

ʻO ia ka hoʻohana maopopo. Akā aia kekahi mea ʻike ʻole ʻia: i loko o ka module i hoʻopau ʻia, Hoʻopili ʻia ka lipine PTFE a puni nā busbar kahi e hele ai lākou ma nā puka backsheet, e pale ana i ke kolo kiʻekiʻe. No nā ʻōnaehana 1500V (maʻamau i kēia lā), he mea palekana kēia insulation.

Hoʻolako ʻia ʻo Aokai PTFE i nā ʻano ʻelua - kaʻina hana a me ka insulation mau - me nā koi ʻokoʻa. E hele kāua ma kahi e hele ai ka lipine PTFE i loko o kahi module PV, a he aha nā waiwai no kēlā me kēia wahi.

Kahi i hoʻohana ʻia ai ka lipine PTFE ma ka hana ʻana o ka module solar

ʻAʻole hoʻokahi noi - ʻelima.

Palekana ʻo Laminator Edge - Ke kaua ʻana i ka EVA Stickiness

I ka lamination (145-165°C, 15-25 minuke), hehee a kahe ka EVA encapsulant. ʻO kekahi poʻe hiki ʻole ke ʻoki i nā ʻaoʻao. Inā pili ia i ka pā metala metala a i ʻole ka silicone vacuum diaphragm, paʻa mau ia.

1. Pehea e hoʻoponopono ai ka tape PTFE

ʻO ka lipine PTFE i hoʻopili ʻia i kēia mau ʻili e hoʻōla ʻia ʻo EVA i hoʻokahi ʻāpana. Holoi nā mea hana i ka lipine me kahi lole ma waena o nā pōʻai, a hoʻokahi pule hoʻokahi pule.

2. He aha ka mea e nānā ai i kahi lipine lamination

• Lapaʻa: PTFE i hoʻoikaika ʻia i ka fiberglass (0.13-0.18mm). He maʻalahi loa ka waimaka PTFE maʻemaʻe i ka wā e ʻoki ai i ka EVA i hoʻōla ʻia.

• Hoʻopili: Silicone PSA wale nō. Hoʻomaʻamaʻa a hoʻoheheʻe ka Acrylic ma 150 ° C, e hoʻohaumia i ka laminator.

• Ka emi ʻana o ka wela: ʻAʻole hiki ke hoʻopaʻa ʻia i ka wela o ka lamination - ʻaʻole pono ka lipine wili a hōʻike paha i nā kihi metala.

• Haʻahaʻa haʻahaʻa haʻahaʻa: Ma lalo o ka lamination vacuum, hiki i nā volatiles mai ka hoʻopili maikaʻi ʻole ke hoʻoulu i nā ʻōhū i loko o ka module. ʻO ka nui o ka pohō <1% kahi pahuhopu maikaʻi.

Mai ka papahele o ka hale hana : Ua hōʻike ʻia kekahi mea hana module e hōʻemi ana i ka manawa hoʻomaʻemaʻe laminator mai 45 mau minuke i kēlā me kēia neʻe i 5 mau minuke ma hope o ka hoʻololi ʻana i kahi lipine PTFE kākoʻo fiberglass premium me ka hoʻopili silicone kiʻekiʻe crosslink. ʻOi aku ke kumukūʻai o ka lipine ma mua akā ua uku ʻia iā ia iho i loko o ʻelua pule.

ʻO ka hoʻokuʻu ʻana i ka Busbar mau loa - Pono ka hilinaʻi 25-makahiki

I loko o ka module i hoʻopau ʻia, hoʻopili nā busbars (lipine keleawe i loko) i nā kaula kelepona i ka pahu hui. Ma kahi e hele ai lākou ma kahi ʻāpana o ka pepa hope, a i ʻole e kūlou kokoke i ke kumu alumini, hiki ke paʻa ka ʻae ʻana. Hoʻopili ka lipine PTFE a puni ka busbar ma kēia mau wahi.

kēia lipine ʻAʻole hiki ke hoʻohana ʻia . Pono e mau ke ola o ka module - 25 mau makahiki a ʻoi aku paha - ma waho, ma lalo o UV, ke kaʻa kaʻa wela (-40°C a +85°C), a me ka wela pulu (85°C/85% RH).

1. Nā kikoʻī koʻikoʻi no ka lipine insulation busbar

ʻIke ʻoihana: Hoʻohana kekahi mau mea hana modula kumu kūʻai haʻahaʻa i ka tape polyimide (Kapton) no ka pale ʻana i ka busbar. ʻOiai ʻoi aku ka ikaika o ka dielectric o ka polyimide, hoʻopaʻa ʻo ia i ka makū a hiki ke nalowale i nā waiwai insulation i ka wela wela. Noho paʻa ka PTFE. No nā modula 1500V, hoʻonui ʻia ka PTFE.

Hoʻopaʻa Paʻa a me ka Hoʻopaʻa ʻana i ka pahu Junction

I loko o ka pahu hui, hoʻopili ka huelo busbar i ka poloka diode/terminal. ʻElua kuleana o ka tape PTFE: ʻo ka hoʻokaʻawale ʻana i kahi kokoke i nā mea hoʻokele ʻole, a me ka hoʻoponopono ʻana i ka mīkini - ʻo ka hoʻopaʻa ʻana i nā uea i lalo e pale i ka luhi haʻalulu.

No ke aha e pono ai ka hoʻopaʻa ʻana i ke ahi

ʻO ka pahu hui kahi kumu e hoʻā ai inā pōkole ka diode bypass. Pono ka lipine PTFE ma aneʻi he helu UL94 V-0. Eia kekahi, pono ia e mālama i ka wela mau mai ka diode (maʻamau 85-90°C) me ka ʻole o ka kolo ʻana a me ka nalowale ʻana o ka pili.

Hana maikaʻi ʻia ka lipine kiʻiʻoniʻoni PTFE (0.05-0.08mm) ma ʻaneʻi no ka mea ua pipili paʻa ʻo ia a puni nā uea a me nā hopena.

Palekana Soldering & Palekana no ka manawa

I ka wā o ka hoʻopaʻa ʻana a me ke kaula ʻana, hiki i ka flux a me ka solder hoʻoheheʻe ʻia ke pāpaʻi ma luna o nā pūnaewele, e hoʻopōʻino ai i nā hemahema a i ʻole micro-cracks. ʻO ka lipine PTFE e uhi i nā ʻaoʻao o ke kelepona a i ʻole nā ​​​​wahi kūʻai ʻole.

Nā koi like ʻole - ʻaʻole pono ka ʻelemakule lōʻihi

ʻO ke kūpaʻa wela kiʻekiʻe wale nō (ka ʻike pōkole i 300°C+ mai ka hao hao), ka ʻili o ka solder-repellent, a ʻaʻohe koena ma hope o ka ʻili ʻana. Hiki paha ke hana i kahi mea hoʻopili acrylic ma ʻaneʻi no ka mea he pōkole ka hoʻolaha ʻana a he kiʻekiʻe ka mahana - akā ʻoi aku ka palekana o ka silicone no kekahi wela ma luna o 200°C.

Pepa hoʻopunipuni koho wikiwiki

Nā mea lawe hope loa

ʻElua mau ʻano lipine PTFE like ʻole e lawelawe i ka ʻoihana PV.

• Kaʻina hana (pale laminator, soldering mask): e nānā i ka lāʻau ʻole, hoʻomaʻemaʻe maʻalahi, a me ka pale wela no ka wā pōkole.

• ʻO ka insulation kūloko mau (busbar wrap, junction box): koi piha i ka IEC 61215 qualification - ka wela wela, ka uila uila, UV, a me ka emi ʻana <1%.

ʻAʻole hiki ke kūkākūkā ʻia ka Silicone PSA no kēlā me kēia lipine e ʻike i ka 150 ° C + a i ʻole 25 mau makahiki i waho.

Hoʻolako ʻo Aokai PTFE i nā ʻāpana ʻelua me nā palapala hoʻāʻo. No ka insulation busbar, hāʻawi mākou i ka ʻikepili ikaika dielectric kahiko wela. No ka lipine lamination, hāʻawi mākou i ka loiloi outgassing a me nā kuhikuhi ola kahua.

Hāʻawi ʻia ka ʻike loea ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.

No nā kikoʻī kikoʻī, nā hoʻolālā noi, a me nā hoʻonā i hoʻoponopono ʻia no nā huahana piha piha me ka PTFE kiʻekiʻe-mehana lole, PTFE kiʻekiʻe-mehana adhesive tape, PTFE mesh conveyor kāʻei, seamless fusing mīkini kāʻei, hoʻokahi ʻaoʻao PTFE uhi lole, kiʻekiʻe-wela kūʻē i ke kāʻei conveyor a me ka lole fiberglass , e ʻoluʻolu e kelepona mai iā mākou:

• Mr. Guo: +86 18944819998

• Mr. Liu: +86 13705266308

Ke kākoʻo nei i ka ʻoihana a me ka kūpaʻa, hāʻawi mākou i nā hoʻonā ʻenehana kū hoʻokahi a me ka lawelawe ma hope o ke kūʻai aku.
