Ingcaciso yeMveliso
Iingenelo zefilimu ye-solar cell encapsulation (EVA) zishwankathelwe ngolu hlobo lulandelayo:
1. Ukukhanya okuphezulu kunye nokunamathela okuphezulu kunokusetyenziswa kwiindawo ezahlukeneyo zokunxibelelana, kubandakanya iglasi, isinyithi kunye neplastiki ezifana nePET.
2. Ukuqina okuhle kunokumelana nobushushu obuphezulu, ukufuma, imisebe ye-ultraviolet njalo njalo.
3. Kulula ukuyigcina. Igcinwe kubushushu begumbi, ukunamathela kwe-EVA akuchaphazeleki bubumanzi kunye neefilimu ezifunxayo.
4. Xa ithelekiswa ne-PVB, inefuthe elinamandla lokukhusela isandi, ingakumbi kwizandi ezivakala rhoqo.
5. Indawo yokunyibilika ephantsi, kulula ukuyihamba, ifanelekile kwinkqubo yokulaminetha kwiiglasi ezahlukeneyo, njengeglasi enepateni, iglasi eqinisiweyo, iglasi egobileyo, njl.njl.
Ifilimu ye-EVA isetyenziswa njengeglasi elaminethiweyo, ehambelana ngokupheleleyo nomgangatho wesizwe othi "GB9962-99" weglasi elaminethiweyo. Lo mzekelo ulandelayo ngumzekelo wefilimu ecacileyo enobukhulu obuyi-0.38mm.
Izalathi zokusebenza zezi zilandelayo:

Ziziphi iingenelo kunye neengxaki zefilimu yokupakisha ye-EVA?
Eyona nto iphambili kwifilimu ye-EVA yi-EVA, kunye nezinye izongezo ezahlukeneyo, ezifana ne-agent edibanisayo, i-thickener, i-antioxidant, i-light stabilizer, njl. I-EVA ibe yeyona nto ikhethwayo kwi-photovoltaic module packaging ngaphambi kowama-2014 ngenxa yokusebenza kwayo kakuhle ekupakisheni, ukumelana nokuguga kakuhle kunye nexabiso eliphantsi. Kodwa isiphene sayo se-PID siyabonakala.
Ukuvela kweemodyuli zeglasi ezimbini kubonakala ngathi kunika i-EVA ithuba lokunqoba iziphene ezikhoyo. Ekubeni izinga lokudluliselwa komphunga wamanzi kwiglasi liphantse libe zero, ukungena kwamanzi okuphantsi okanye ukungena kwamanzi okungeyo-zero kwiimodyuli zeglasi ezimbini kwenza ukuxhathisa i-hydrolysis ye-EVA kungabi yingxaki.
Amathuba kunye nemingeni yeefilimu zokupakisha ze-POE
Iphuhliswe kwii-catalysts ze-metallocene, i-POE luhlobo olutsha lwe-polyolefin thermoplastic elastomer enokusasazwa okuncinci kwe-molecular mass, ukusasazwa okuncinci kwe-comonomer kunye nesakhiwo esilawulekayo. I-POE inamandla okukhusela umphunga wamanzi kunye nokukwazi ukukhusela i-ion. Izinga lokudluliselwa komphunga wamanzi limalunga ne-1/8 ye-EVA kuphela, kwaye inkqubo yokwaluphala ayivelisi izinto ezine-asidi. Isebenza kakuhle kakhulu ekulweni nokwaluphala kwaye isebenza kakuhle kakhulu kwaye ithembekile kakhulu kwi-photovoltaic. Zizinto ezikhethwayo kwiifilimu ze-component encapsulation.
Inkqubo yokondla ye-gravimetric ezenzekelayo iqinisekisa ukuba kukho iintlobo ngeentlobo zezongezo eziqinileyo, ezingamanzi kunye nezinto eziluhlaza ezichanekileyo. Iinkqubo zokukhupha ubushushu obuphantsi ukuqinisekisa ukuxubana okwaneleyo kwindawo yokufakelwa kweplastiki ukuthintela izongezo ezidibanisayo. Uyilo olukhethekileyo lwenxalenye yeCasting lunika isisombululo esifanelekileyo sokuthintela ukuqhekeka kwe-roller kunye nokuchitheka kwamanzi. Isixhobo esikhethekileyo sokupholisa kwi-intanethi sokususa uxinzelelo lwangaphakathi. Inkqubo yokulawula uxinzelelo iqinisekisa ukuba amaphepha aguquguqukayo ahambisa kakuhle ngexesha lokupholisa, ukutsala kunye nenkqubo yokujika. Inkqubo yokulinganisa ubukhulu kwi-intanethi kunye nokuhlola iziphene inokubonelela ngempendulo yexesha langempela yomgangatho wemveliso yefilimu yelanga ye-EVA/POE.
Ifilimu ye-photovoltaic ye-EVA/POE isetyenziswa kakhulu ekufakweni kweemodyuli ze-photovoltaic kwaye yeyona nto iphambili kwiimodyuli ze-photovoltaic; Ingasetyenziswa nakwimizi-mveliso eyahlukeneyo efana nodonga lweglasi yoyilo, iglasi yeemoto, iglu enyibilikayo eshushu, njl.njl.
