Liliphi ithemba lesicelo se-photovoltaic welding strip rolling mill

       Njengesixhobo esingundoqo sokuveliswa kwe-photovoltaic welding strip, ithemba lesicelo se-photovoltaic welding strip rolling mill ixhomekeke ekukhuleni okugqabhukileyo kweshishini le-photovoltaic. Kwangaxeshanye, ixhamla ekuphuculweni kwetekhnoloji ye-welding strip kunye nomkhwa wokutshintsha izixhobo zasekhaya. Lilonke, libonisa umkhwa olungileyo wemfuno eyomeleleyo, ukuphuculwa kwetekhnoloji eqhutywa, kunye nokwandiswa okuqhubekayo kwendawo yentengiso. Uhlalutyo oluthile lunokwenziwa kule miba ilandelayo:

       Ukwandiswa kwemboni ye-photovoltaic kuzisa imfuno eqhubekayo: Iribhoni ye-Photovoltaic yaziwa ngokuba "yisitya segazi" seemodyuli ze-photovoltaic kwaye iyona nto ingundoqo encedisayo yokudibanisa iiseli zelanga. Ukuqengqeleka kunye nezinye iinkqubo ze-photovoltaic ribbon rolling mill zicacisa ngokuthe ngqo ukuchaneka kunye nomgangatho weribhoni, nto leyo echaphazela amandla okuvelisa amandla kwiimodyuli ze-photovoltaic. Ukuqhutywa zinjongo zekhabhoni ezimbini zehlabathi, imboni ye-photovoltaic ikhula ngokukhawuleza. Kwisiqingatha sokuqala se-2025, amandla e-photovoltaic esanda kufakwa e-China afikelele kwi-212.21GW, ukunyuka konyaka-ngonyaka we-107.07%; Imfuno yehlabathi jikelele yeribhoni ye-photovoltaic iya kudlula i-1.2 yezigidi zeetoni kwi-2023 kwaye kulindeleke ukuba ifike kwi-2 yezigidi zeetoni ngo-2025. Ukwandiswa okuqhubekayo kweemodyuli ze-photovoltaic ezisezantsi ngokuqinisekileyo kuya kuqhuba imfuno enkulu ye-photovoltaic welding strips, ngaloo ndlela ivula indawo ezinzileyo kunye nenkulu yemarike ye-rolling strips mills. Kwaye kwixesha elizayo, amacandelo amatsha aqhelekileyo afana ne-heterojunctions kunye ne-TOPCon isasebenzisa i-ribbon ye-photovoltaic njengendlela yokudibanisa eyona ndlela, iqinisekisa ngakumbi imfuno yexesha elide le-rolling mills.

       Uphuculo lwetekhnoloji ye-welding strip inyanzelise ukuphindaphinda kwezixhobo kwaye yenze ukunyuka okutsha: i-photovoltaic welding strips iphuculwa kwicala legridi ephambili, i-ultra-thin, kunye neemilo ezingaqhelekanga. Ngokomzekelo, imfuno ye-welding strips engaphantsi kwe-0.08mm kunye ne-regular section welding strips iyanda imihla ngemihla. Ezi zicuku zokuwelda ezichanekileyo zifuna ukuchaneka okuphezulu kakhulu kunye nokukwazi ukulawula ukunyamezela kwesixhobo sokusila, kunye nezixhobo zokusila eziqhelekileyo kunzima ukuziqhelanisa nazo. Ngokomzekelo, amacandelo amatsha afana ne-HJT kunye ne-TOPCon afuna i-welding strips kunye nokunyamezela kobunzima obulawulwa ngaphakathi kwe-± 0.005mm, eqhuba iinkampani ze-photovoltaic ukuba ziphelise izixhobo zemveli kunye nokuthenga ii-rolling mill ezintsha ezinobuchule obuphezulu bokujikeleza. Ukongeza, imfuno yokonga umbane kunye nokunciphisa iindleko kwimveliso ye-welding strip nayo ikhuthaze ukuphindaphindwa kwee-rolling mill. Umzekelo, i-Jiangsu Youjuan ye-photovoltaic welding strip rolling mill yehlisa ukusetyenziswa kwamandla ngama-25% ngenkqubo yolawulo lwe-servo. Ezi mill zonga amandla zinokunceda amashishini anciphise iindleko zemveliso kwaye aya kuba yeyona nto iphambili kwintengiso, eqhuba imfuno yokuphuculwa kwezixhobo.

       Ukukhawuleziswa kokutshintshwa kwekhaya kunye nethemba elibanzi lezixhobo zendawo: Ngaphambili, i-high-end photovoltaic strip rolling mills yayilawulwa yi-European and American brands ixesha elide. Akunjalo kuphela ixabiso leyunithi enye ngaphezulu kwe-50% ephezulu kunezixhobo zasekhaya, kodwa umjikelo wokuhanjiswa wawumde kangangeentsuku ezingama-45-60, kwaye wawuchaphazeleka nokuguquguquka kwekhonkco lonikezelo lwamazwe ngamazwe. Kwiminyaka yakutshanje, itekhnoloji yasekhaya yokusila yenze inkqubela ekhawulezileyo, yafikelela kumanqanaba aphakamileyo kumazwe ngamazwe ngokuchaneka, ukusebenza kakuhle kwamandla, kunye neminye imiba. Umzekelo, ii-mills zasekhaya eziqengqelekayo zinokufikelela kulawulo lwe-welding strip yokunyamezela ukutyeba ± 0.005mm, kunye nokusetyenziswa kwamandla malunga ne-25% engaphantsi kwezixhobo ezithunyelwa kwamanye amazwe, kwaye ixabiso li-60% -70% kuphela yezixhobo ezithunyelwa kwamanye amazwe. Umjikelo wokuhanjiswa uyancitshiswa ukuya kwiintsuku ezingama-20-30. Ngelo xesha, abavelisi basekhaya banokubonelela ngeenkonzo ezilungelelanisiweyo, kwaye banokubonelela ngezisombululo ezilungiselelwe ngaphakathi kweentsuku ezi-3 ukulungelelanisa ukuveliswa kweempawu ezahlukeneyo ze-welding strips. Ezi zibonelelo zenza ukuba i-photovoltaic strip rolling Mills yasekhaya ithathe indawo yezixhobo ezisuka kumazwe angaphandle, kwaye isabelo sabo semakethi kurhwebo lwasekhaya nakwihlabathi jikelele kulindeleke ukuba siqhubeke sikhula kwixesha elizayo.

        Amanqaku entlungu kwishishini kufuneka aqwalaselwe ngokukhawuleza, kwaye ababoneleli bezixhobo eziphezulu bajongene namathuba ophuhliso. Okwangoku, i-80% yabavelisi abancinci nabaphakathi kwishishini le-photovoltaic welding strip bathembele kwii-mill rolling zemveli, ezineengxaki ezifana nokusetyenziswa kwamandla aphezulu, isivuno esiphantsi, kunye ne-homogenization enzulu. Ukusetyenziswa kwamandla kwezixhobo zabanye abavelisi ngama-20% -30% ngaphezulu kunezixhobo eziphambili, kwaye imveliso yemveliso ye-welding strip ingaphantsi kwama-85%. Ukongeza, imigaqo-nkqubo yokusingqongileyo ikwanyanzelisa ii-rolling Mills kunye nongcoliseko oluphezulu kunye nokusetyenziswa kwamandla ukuphuma kwimarike. Kulo mongo, i-photovoltaic strip welding kunye nabavelisi be-rolling mill kunye nokugcina amandla, ukunciphisa iindleko, ukuchaneka okuphezulu, kunye nobuchule bokwenza ngokwezifiso abanakukwazi ukucombulula iintlungu zeshishini kuphela, kodwa bancede abavelisi abancinci nabaphakathi bahlangabezane nokukhuselwa kwendalo kunye neemfuno zokuvelisa. Ukwamkelwa kweemarike ezinjalo zomgangatho ophezulu wokuqengqeleka kuya kuqhubeka nokunyuka, kwaye iimeko zabo zesicelo ziya kwandisa ngakumbi ukusuka kumashishini emveli ye-photovoltaic strip welding ukuya kwinani elikhulu labavelisi abancinci nabaphakathi.
