Ngaba imfuno yeengxowa ze-EVA kwimboni ye-photovoltaic ikhula ngokukhawuleza?
Xa kuhlolwa izinga lokukhula kwemfuno yeIingxowa ze-EVAkwimboni ye-photovoltaic, kufuneka siyihlalutye kwii-angles ezininzi, kubandakanywa ukunikezelwa kweemarike zangoku kunye neemeko zemfuno, iindlela zokuphuhliswa kweshishini, kunye nefuthe lophuhliso olukhawulezayo lwemboni ye-photovoltaic kwimfuno yezinto ze-EVA.

1. Uphuhliso olukhawulezayo lwemboni ye-photovoltaic
Imboni ye-photovoltaic ibonise ukukhula okukhulayo kwihlabathi jikelele kwiminyaka yamuva. Ngokukodwa e-China, umthamo osanda kufakwa we-photovoltaics ufikelele kwi-78.42GW kwisiqingatha sokuqala se-2023, ukunyuka okumangalisayo kwe-153.95% xa kuthelekiswa nexesha elifanayo kwi-2022. Oku kukhula kwakhuthaza ngokuthe ngqo imfuno yezinto ze-EVA, njengoko i-Eva yenye yezinto eziyimfuneko. izixhobo zemodyuli ye-photovoltaic encapsulation.

2. Ukusetyenziswa kwezinto ze-EVA kwimboni ye-photovoltaic
I-EVA (i-ethylene-vinyl acetate copolymer) isetyenziswa ngokubanzi kwimveliso yeefilimu ze-photovoltaic ngenxa yeempawu zayo ezibalaseleyo zomzimba. Iifilimu ze-Photovoltaic zizinto eziphambili kwiimodyuli ze-photovoltaic, ezisetyenziselwa ukudibanisa nokukhusela iiseli zelanga. Ngenkqubela phambili yetekhnoloji yeshishini le-photovoltaic, imfuno yefilimu ye-EVA nayo iyakhula, ngakumbi kuphuhliso lwetekhnoloji yemodyuli yebhetri ye-N, imfuno yefilimu ye-POE / EPE iyaqhubeka nokukhula.

3. Izinga lokukhula kwemfuno yezinto ze-EVA
Ngokutsho kohlalutyo lweemarike, ifilimu ye-photovoltaic ibe yeyona ndawo ifunwa kakhulu kwindawo esezantsi ye-EVA, kwaye isabelo sayo siye saqhubeka sikhula, ukusuka kwi-33.3% kwi-2020 ukuya kwi-58.44% ngoJanuwari-Oktobha 2023. Kuqikelelwa ukuba ngo-2025, i-domestic ukusetyenziswa kwe-photovoltaic-grade EVA kuya kufikelela malunga ne-1.956 yezigidi zeetoni, kubalwa ngaphezu kwe-50% yokusetyenziswa kwe-EVA iyonke. Le datha ibonisa ukukhula ngokukhawuleza kwemfuno yezinto ze-EVA kwishishini le-photovoltaic.

4. Ubume bokubonelela kunye nemfuno kunye noqikelelo lwexesha elizayo
Ngo-2022, umthamo wemveliso we-EVA waseTshayina uya kufikelela kwi-2.15 yezigidi zeetoni / ngonyaka, kunye nemveliso yonyaka malunga ne-1.676 yezigidi zeetoni kunye nokusetyenziswa malunga ne-2.761 yezigidi zeetoni. Izinga lokuzimela liza kunyuka ukusuka kwi-49.1% ngo-2021 ukuya kuma-60.7%. Kuqikelelwa ukuba ngo-2025, amandla okuvelisa i-EVA yasekhaya aya kudlula i-5 yezigidi zeetoni / ngonyaka kwaye ukusetyenziswa kuya kudlula i-3.6 yezigidi zeetoni / ngonyaka. Ukusetyenziswa kwe-EVA kwintsimi yefilimu ye-photovoltaic kulindeleke ukuba ibe yimarike ekhula ngokukhawuleza, kwaye ukusetyenziswa kwayo kuya kubalelwa ngaphezu kwe-50% nge-2025.

5. Isiphelo
Ngokusekelwe kuhlalutyo olungentla, sinokugqiba ukuba imfuno yeephakheji ze-EVA kwimboni ye-photovoltaic ikhula ngokukhawuleza. Ngokugxininiswa kwehlabathi kumandla avuselelweyo kunye nophuhliso oluqhubekayo lwemboni ye-photovoltaic, imfuno yemarike yezinto eziphathekayo ze-EVA, njengento ephambili yokupakisha iimodyuli ze-photovoltaic, iya kuqhubeka ikhula ngokukhawuleza. Uphuhliso olukhawulezayo kunye nokutsha kwezobuchwepheshe kwimboni ye-photovoltaic kuya kukhuthaza ukukhula kwemfuno yezinto ze-EVA, ezibonisa ukuba amathuba okusetyenziswa kwezinto ze-EVA kwishishini le-photovoltaic libanzi.
