Ingabe isidingo sezikhwama ze-EVA embonini ye-photovoltaic sikhula ngokushesha?
Lapho uhlola izinga lokukhula kwesidingo seIzikhwama ze-EVAembonini ye-photovoltaic, kufanele siyihlaziye kusukela ema-engeli amaningi, kuhlanganise nesimo samanje sokuhlinzekwa kwemakethe nesimo sokufunwa, izitayela zokuthuthukiswa kwemboni, kanye nomthelela wokuthuthukiswa okusheshayo kwemboni ye-photovoltaic ekudingeni izinto ze-EVA.

1. Ukuthuthukiswa okusheshayo kwemboni ye-photovoltaic
Imboni ye-photovoltaic ibonise ukukhula okuqhuma emhlabeni wonke eminyakeni yamuva. Ikakhulukazi e-China, umthamo osanda kufakwa we-photovoltaics ufinyelele ku-78.42GW engxenyeni yokuqala ka-2023, ukukhuphuka okumangazayo okungu-153.95% uma kuqhathaniswa nesikhathi esifanayo ngo-2022. Lokhu kukhula kukhuthaze ngokuqondile isidingo sezinto ze-EVA, njengoba i-EVA ingenye yezinto ezibalulekile. izinto zokwakha ze-photovoltaic module encapsulation.

2. Ukusetshenziswa kwezinto ze-EVA embonini ye-photovoltaic
I-EVA (i-ethylene-vinyl acetate copolymer) isetshenziswa kabanzi ekukhiqizeni amafilimu e-photovoltaic ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba. Amafilimu e-Photovoltaic ayizinto ezibalulekile zamamojula we-photovoltaic, asetshenziselwa ukuhlanganisa nokuvikela amaseli elanga. Ngokuthuthuka kwezobuchwepheshe embonini ye-photovoltaic, isidingo sefilimu ye-EVA siyakhula, ikakhulukazi ekuthuthukisweni kobuchwepheshe bemojula yebhethri yohlobo lwe-N, isidingo sefilimu ye-POE/EPE siyaqhubeka nokukhula.

3. Izinga lokukhula kwesidingo sezinto ze-EVA
Ngokusho kokuhlaziywa kwemakethe, ifilimu ye-photovoltaic isiphenduke indawo enkulu kunazo zonke efunwa kakhulu endaweni ephansi ye-EVA, futhi isabelo sayo siye saqhubeka sikhula, sisuka ku-33.3% ngo-2020 saya ku-58.44% ngoJanuwari-Okthoba 2023. Kulinganiselwa ukuthi ngo-2025, abasekhaya. ukusetshenziswa kwe-photovoltaic-grade EVA kuzofinyelela cishe amathani ayizigidi ezingu-1.956, okubalwe ngaphezu kwe-50% yengqikithi yokusetshenziswa kwe-EVA. Le datha ikhombisa ukukhula okusheshayo kwesidingo sezinto ze-EVA embonini ye-photovoltaic.

4. Isimo sokuhlinzeka nokufunwa kanye nezibikezelo zesikhathi esizayo
Ngo-2022, umthamo wokukhiqiza we-EVA waseChina usuwonke uzofinyelela kumathani ayizigidi ezi-2.15/ngonyaka, ngomkhiqizo wonyaka wamathani ayizigidi eziyi-1.676 kanye nokusetshenziswa kwamathani ayizigidi ezi-2.761. Izinga lokuziphilisa lizokhuphuka lisuka ku-49.1% ngo-2021 liye ku-60.7%. Kulinganiselwa ukuthi ngo-2025, umthamo wokukhiqiza we-EVA wasekhaya uzodlula amathani ayizigidi ezi-5 ngonyaka futhi ukusetshenziswa kuzodlula amathani ayizigidi ezingu-3.6 ngonyaka. Ukusetshenziswa kwe-EVA emkhakheni wefilimu we-photovoltaic kulindeleke ukuthi kube imakethe ekhula ngokushesha, futhi ukusetshenziswa kwayo kuzoba ngaphezu kwama-50% ngo-2025.

5. Isiphetho
Ngokusekelwe ekuhlaziyweni okungenhla, singaphetha ngokuthi isidingo samaphakheji we-EVA embonini ye-photovoltaic sikhula ngokushesha kakhulu. Ngokugcizelelwa komhlaba wonke emandleni avuselelekayo kanye nokuthuthukiswa okuqhubekayo kwemboni ye-photovoltaic, isidingo semakethe sezinto ze-EVA, njengento ebalulekile yokupakisha amamojula we-photovoltaic, izoqhubeka ikhula ngokushesha. Ukuthuthukiswa okusheshayo kanye nokusha kwezobuchwepheshe embonini ye-photovoltaic kuzothuthukisa ukukhula kwesidingo sezinto ze-EVA, okubonisa ukuthi amathemba okusetshenziswa kwezinto ze-EVA embonini ye-photovoltaic abanzi.
