Baahida bacaha EVA ee warshadaha sawir-qaadista ma si dhakhso leh ayey u koraysaa?
Marka la sahaminayo heerka kobaca baahidaBacaha EVAwarshadaha sawir-qaadista, waa in aan ka falanqeynaa dhinacyo badan, oo ay ku jiraan saadka suuqa ee hadda jira iyo xaaladda baahida, isbeddellada horumarinta warshadaha, iyo saameynta horumarka degdega ah ee warshadaha sawir-qaadista ee baahida alaabta EVA.

1. Horumarinta degdega ah ee warshadaha sawir-qaadista
Warshadaha sawir-qaadista ayaa muujiyay kobaca qarxa adduunka oo dhan sannadihii la soo dhaafay. Gaar ahaan Shiinaha, awoodda cusub ee la rakibay ee sawir-qaadista waxay gaartay 78.42GW qeybtii hore ee 2023, koror la yaab leh 153.95% marka la barbardhigo isla muddadaas 2022. Kobacani wuxuu si toos ah kor ugu qaaday baahida alaabta EVA, maadaama EVA ay tahay mid ka mid ah lama huraanka agabka loogu talagalay koobiynta moduleka sawir-qaadista.

2. Codsiga walxaha EVA ee warshadaha sawir-qaadista
EVA (etylene-vinyl acetate copolymer) ayaa si weyn loogu isticmaalaa soo saarista filimada sawir-qaadista sababtoo ah sifooyinka jireed ee wanaagsan. Filimada sawir-qaadista ayaa ah agab muhiim ah oo loogu talagalay qaybaha sawir-qaadista, oo loo isticmaalo in lagu koobo oo lagu ilaaliyo unugyada qorraxda. Horumarka tignoolajiyada ee warshadaha sawir-qaadista, baahida filimka EVA ayaa sidoo kale sii kordheysa, gaar ahaan horumarinta tignoolajiyada moduleka batteriga nooca N-nooca, baahida filimka POE / EPE ayaa sii socota inay koraan.

3. Heerka kobaca baahida agabka EVA
Marka loo eego falanqaynta suuqa, filimka sawir-qaadista ayaa noqday aagga baahida ugu weyn ee EVA-ga hoose, saamigeeda ayaa sii waday inay korodho, laga bilaabo 33.3% 2020 ilaa 58.44% Janaayo-Oktoobar 2023. Waxaa lagu qiyaasaa in 2025, gudaha gudaha Isticmaalka heerka sawir-qaadista EVA wuxuu gaari doonaa ilaa 1.956 milyan oo tan, taasoo ka dhigan in ka badan 50% wadarta EVA isticmaalka. Xogtan ayaa muujinaysa kobaca degdega ah ee baahida agabka EVA ee warshadaha sawir-qaadista.

4. Bixinta iyo dalbashada heerka iyo saadaasha mustaqbalka
Sannadka 2022, wadarta guud ee awoodda wax-soo-saarka EVA ee Shiinaha waxay gaari doontaa 2.15 milyan oo tan/sanadkii, iyada oo wax-soo-saarka sannadlaha ah ee ku saabsan 1.676 milyan oo tan iyo isticmaalka qiyaastii 2.761 milyan oo tan. Heerka isku-filnaanshaha ayaa ka kordho 49.1% sanadka 2021 ilaa 60.7%. Waxaa lagu qiyaasaa in marka la gaaro 2025, awoodda wax-soo-saarka EVA-ga gudaha ay ka badan doonto 5 milyan oo tan/sanadkii isticmaalkana uu ka badnaan doono 3.6 milyan tan/sanadkii. Isticmaalka EVA ee goobta filimka sawir-qaadista ayaa la filayaa inuu noqdo suuqa ugu dhaqsaha badan, isticmaalkiisuna wuxuu xisaabin doonaa in ka badan 50% marka la gaaro 2025.

5. Gabagabo
Iyada oo ku saleysan falanqaynta sare, waxaan ku soo gabagabeyn karnaa in baahida xirmooyinka EVA ee warshadaha sawir-qaadista ay si dhakhso ah u korayaan. Iyada oo xoogga la saarayo tamarta la cusboonaysiin karo iyo horumarinta joogtada ah ee warshadaha sawir-qaadista, baahida suuqa ee alaabta EVA, oo ah baakadaha muhiimka ah ee qaybaha sawir-qaadista, ayaa sii wadi doona inay si degdeg ah u koraan. Horumarka degdega ah iyo hal-abuurka tignoolajiyada ee warshadaha sawir-qaadista ayaa sii kordhin doona kobaca baahida agabka EVA, taas oo muujinaysa in rajada codsiga ee agabka EVA ee warshadaha sawir-qaadista ay yihiin kuwo ballaadhan.
