Ukubuyisela kwe-PC Panel kubonakala kakhulu, isikhundla sokugcina isikhundla sokugcina sokunyuswa kwezinhlelo zokusebenza ezinhlakaniphe

Amaphaneli e-PC asebenziwe ngokwesandla akasenziwa ngokuphazimula—Ukubuyisela kuyavula indawo entsha yendustri

Ukusebenzisa amaphaneli e-polycarbonate (PC) ngokukhulu kwenza isibonelo sokuziphatha kwezinto ezisemthwakini nezinye izinto zokugcina. Kukhona emizwakweni yezindaba ezenzeki kusasa, abanqambu bafundwa ukuthi ngokuphazimula kwamandla okuhlelwa kwezulu nokuthuthukisa kwezindustri, ukubuyisela nokusetshenziswa kabusha kwamaphaneli e-PC ayebuka ku “isibonelo esingathathiwa ngokuphazimula” ku “isibonelo esikhulu sesayensi”—futhi indawo yendustri yokuhlaka okuhle kuyadala ngokushisana kwezindlela zokubuya, ukuchaza, nokwenza kabusha.

Kuphi kufika amaphaneli e-PC asebenziwe ngokwesandla?

Umsebenzi wokusebenza kwe-PC panels ubalulekile kakhulu kusukela ku-10 ku-25 iminyaka. Ngokuphakanyiswa kwemithombo yokuqala yokusebenzisa izimpahla, kuyaphakanywa kuzo izimpahla zokubuyisela eziphakanyiwe ngokuphakanyiswa kwazo, isivinini sokugcina izimpahla zokusebenzisa kwe-PC siphakanyiswa ngokuphakanyiswa kwazo iminyaka yonke. Ngalesikhathi, izimpahla ezinkulu zokugcina izimpahla zokusebenzisa kwe-PC zidonselwa emlandweni noma zihlomulwa njengamathuba amaningi okugcina izimpahla—okungakwazi ukuthi kuyadonsela izinto ezibalulekile kodwa kusho nokuthi kungabangela ukuthi kuzwe izimpahla ezimbi.

Lokhu kuyaphinda kuchange. Izinhlanganisi eziningi zokuproducwa kwe-PC panels zibegcina ukuthi zifunde izinhlanganisi zokubuyisela, zinikeza izinkundla zokubuyisela izimpahla zabo. Emva kokubuyiselwa, izimpahla zokusebenzisa kwe-PC zifundwa ngokufunda, ukuthatha izimpahla, nokuthatha izimpahla, futhi izinto ezifundwe zingashintsha ukuthi ziyasebenza njengamathuba amaningi okuproducwa kwe-PC—njengamathuba angavisi, izimpahla yezindustria, izimpahla yokubuyisela kwezinsiza, nezimpahla zokusebenzisa kwezilivu—okuthi kuyasebenza ngokuphelele kwezimpahla zokusebenzisa.

Umndali wezindlela zokuvumela izinhlelo zemvelo emsebenzini waphendula ababhalisi ukuthi ngokwesikhathi esingaka 2024, isikampani sasibonisa “ukubuyisela” isimo sokubuyisa izinto. Uma abasebenzisi bafaka izihlangu zesithunzi se-PC emakhaya abo, bangathwala izihlangu zezinhloso kusikampani ukuze kwenziwe ukubuyisa nokuhlinzeka kusenqumeni. Lokhu kunciphisa uburdeni bebasebenzisi bokuthi bafakaze izinto, futhi kuvula umkhakha omusha wokubuyisa izinto ezibalulekileyo kusikampani.

“Sishiyisela isimo lokuqala emizini eyafanelekileyo futhi sithola impendulo enkulu yokuphepha,” utshilo lwathi. “Abaningi abasebenzisi abazange bazi ukuthi kufanele bakwenze nini izihlangu zezinhloso ngaphambi kokwakhiwa—manje bane indlela efanelekileyo neyenzela yokuqiniseka. Kusikampani, nokuba isimo lokubuyisa kongena izindlela zokusebenza, kuyabuyisa ubuhlelwano bebasebenzisi futhi kuyabuyisa izinkundla zethu zemvelo, okuyisilungelo esibalulekileyo kumarket yamanje.”

Ukuthuthukiswa Kwemithombo Yokuqonda Kuyabuyisa Isimo Lokubuyisa Okubalulekileyo

Nakuba ukuthi kuyisikhathi esihle, ukubuyisela amaphaneli e-PC akhona izinkinga zokusebenza eziningi. Ngoba amaphaneli e-PC abuyiselwa kusukela emva kokusebenzisa kuleli xesha elide ngaphandle kwendawo—kungakhathaliseki ukubhala kwezinye izinyathelo, ukunciphisa kwezinye izinyathelo, nokuphazimula—ukusebenza kwamaphaneli okubuyiselwa ngokuzenzakalelayo kunokwenzeka ukuphulukana kakhulu. Kunezinye izindawo, ukuphulukana kwezinye izinyathelo kungabinga phansi kwe-20% ukuze 40% kulokho okwenziwa ngokuzenzakalelayo, okuvumela ukuthi umsebenzi wokubuyiselwa ungavumelekile.

Ukuzosola lokho, abasebenzi basektor ayisebenzisa izindlela eziningi zokusebenza. Indlela yokuqala iyisikhwama sokufaka amasikhunga ekuphinde kusebenziswa ukuthi kubuyeke kubonakaliswe ukubambisana phakathi kwezinye izinyathelo zokubuyiselwa nezinye izinyathelo ezinewona, ukubuyisa izinyathelo zokusebenza. Indlela eyokuqala iyisikhwama sokubambisa izinye izinyathelo zokubuyiselwa nezinye izinyathelo ezinewona, njengezinye izinyathelo zokuphulukana nokubambisa izinye izinyathelo zokubuyiselwa nezinye izinyathelo zokubuyiselwa, ukwenza isikhumba sokubuyiselwa esifanele kwezinye izinye izinyathelo zokusebenza.

Kwakukodwa, abazalwane nabahleli bafunda izindlela zokusebenzisa ukususa isibonelo esikhulu sokubuyisela kwe-PC. Ngemisebenzi yokuqondisa okanye ukususa ngamandla amanzi, isibonelo sesihluku se-PC singasuswa ku-monomers yakho—njenge-bisphenol A (BPA) nezindlela zokwenza izinkampani zokufaka amandla—okwakungaba kuthulunywa futhi kubuyiselwa kwezibonelo zesihluku se-polycarbonate esishesha. Nakuba ukususa isibonelo ngemisebenzi yamandla kuzoba nengakhulu kakhulu kulokusebenzisa ukususa isibonelo ngemisebenzi yamandla, abahleli basekhaya bavuma ukuthi njengoba izindlela zizweleka, izindlela zokusebenza zizama phansi, nokuthi izimboni zokugcina umhlaba zizama kakhulu kuzo zokuproducwa kwezibonelo ezingapheliyo, ukususa isibonelo ngemisebenzi yamandla kungabecala indlela enkulu yokubuyisela kwezibonelo zesihluku se-PC ngendlela enkulu yokubuyisela.

Ukuthuthukisa kwezimboni nokuthuthukisa kwezindawo zokuthengisa

Izinhlangano zezwe leChina zizokuthi izimboni zokulawula ukuphutha kweplastiki nezinkinga zokugcina umsebenzi wokwenza izinto (EPR) ziyabeka isibonelo esikhulu sokulawula ukubuyisela amaphaneli we-PC. I-Ministry of Ecology and Environment yasusumela izindlela ezingakuthi ukubuyisela nokusebenzisa futhi izinto zokukhupha kwe-engineering plastics, kungakhathaliseki i-PC, emazwe amaningi okusebenza njengezindawo zokwakha nezindawo zokusebenza kwe-automotive.

Ngokwemilinganiselo yezindustria, ukugcina kwamaphaneli we-PC okwesikhathi esihlwa kweChina kuzoba ngama-50,000 kuze kube ngama-80,000 metric tons ngonyaka, kulo lonke lokho okungafana nangama-20% kuphela okuyabuyiselwa ngendlela efanelekileyo. Ngokuthi ukugcina kwamaphaneli we-PC kuyadlala kanye nokufika kwazo kwezinyanga zokugcina kwezinyanga ezibalulekileyo, lo mbala uyakwazi ukuphakama kakhulu ngonyaka eyodwa—kuyadala indawo enkulu yokuthenga izinkampani zokubuyisela nokuthenga izintshayelelo zokubuyisela.

Amakhasi amabili okukhokha amanqamuzana ayisikithi kakhulu. Kusayizwa ukuthi amakhasi amabili okukhokha amanqamuzana okukhokha izinto ezibalulekileyo zokusebenza ngokwezinye zazifundiswa ngokufundisa kwe-Series A ngohalf of this year, nokho abantu ababili bayasebenzisa ukukhokha kwe-closed-loop yezinto ezibalulekileyo zokusebenza ngokwezinye nezinye zezinto ezibalulekileyo zokusebenza ngokwezinye.

Amagama Akhawuli

Ukuphulaphula kwesintu sokubaluleka kwezinye ziyinkimbinkimbi zokuvikela umhlaba ezinamandla. Ngokuba yizinto ezibalulekileyo zokusebenza ngokwezinye, ukukhokha nokusetshenziswa kabusha kwezinye zezinye ziyincazelo yokuvikela umhlaba nokuthuthukisa ukuthuthukisa kwezinye zokusebenza ngokwezinye. Ukubanga isistimu esihle sokubuyisela nokukhokha kwezinye zezinye—futhi ukuthuthukisa ukuthuthukisa kwezinye zokusebenza ngokwezinye zokuvikela umhlaba—kuzodinga ukuthembeka kuka-kuhle kwezinye zokusebenza ngokwezinye, abasebenzisi bezinye, abaphathi bokuvikela umhlaba, nabantu abanamandla. Umendo uyadlula, kodwa indlela iyasibonakala.
