Industri ya Polycarbonate Iyafika Emva Kwezikhathi Zokuthuthukisa Kakhulu, Kuyisindiswa Ngokubuyisela Kwamazwe Nokuthuthukisa Tekhnoloji

Industri ya polycarbonate yaseSina iyaphuma kwezindlela zokuthuthukisa ngokubhala futhi iyafika emva kwezikhathi eziningi zokuguqula isithembiso nesikhathi sokuthuthukisa kakhulu. Ukubuyisela kwamazwe kusukela kusukela, izibonelo zokuthuthukisa tekhnoloji zokuphela, nokuguqulwa kwezidingo zezinye iindawo ziyabecoshisa izincazelo zokuthuthukisa kakhulu zalesi sikhathi, kuyisindiswa ukuthuthukisa kahle komkhakha wendustri.

Ngokubhaqwa njengokugcina kwezinhlobo zezinkulungwane zokuphatha kwezindawo ezikhulu, indusitri yepolycarbonate ibonisa izinhlangothi eziyisisekelo zokuthuthukisa ngokubigqamisa nokuphakanyisa ukugcina. Ngekuphela kwe-2024, isikhundla sakwaChina sokuproducwa kwabuyele emva kwe-3.81 million tons, okubhekana ne-48% yezizinhlobo zokuproducwa kwenyoni yonke. Amaphoyisa amakhulu njenge-Wanhua Chemical ne-Luxi Chemical aqinisekile iziphumo zabo ngokubeka izinhlobo zonke zezindawo zokuproducwa, futhi ukugcina kwezindawo kuthuthukile kahle. Ngokufanayo, umphumela wokubuyela kwezinto zokusebenza kuzo zaseNingizimu kubonakala kahle: ubunikazi bekunika kwezinto zokusebenza kuzo kushiywa kwe-38% ngo-2019 ku-19% ngo-2024, futhi ubunikazi bekunika kwezinto zokusebenza kuzo zezinhlobo zokusebenza kuzo zezinhlobo zokusebenza kuzo zibuye kwe-100%.

Ukuvela kwemithombo yezintshayelelo ekuthintana nezinkinga zokuphakama kuyisibonelo esibalulekile sokuthuthukiswa kwezindustria. Kusasa, i-polycarbonate esihle kakhulu esebenzisa izinkampani zokubona nase-Zhongke Zhenxing ne-PC yocopolymer enesiliconi engu-20% yase-Cangzhou Dahua zavumelana ngokuphakama kwezintshayelelo, zifunda isikhundla sezinsizakwazi zaseNingizimu Afrika, zivula ubulungiswa bezinye izizwe, futhi izindlela zokuhlelwa zezinto ezihlanganisiwe ziyaphikisana nezindlela zezinsizakwazi zasezizwe. Ukuguqula kwezindlela zokwenza ngokuvula amanzi kuyaphinda kuyaphila, nokuvulwa kwesilinganiso sokusebenzisa indlela engenaphosgene kuyaphika ku-65%, okusiza kwezindustria ukufikha izimpendulo zokugcina amandla nokugcina umhlaba.

Isithembiso sesilinganiso sasezantsi siyagcina ukuthintana, futhi izindawo eziphatha kakhulu zizwelela emkhakheni yokwanda. Ukuthinta kakhulu kwesilinganiso sezindawo ezifana nezinhlobo zezibalo zokusebenza ngemvelo, isilinganiso sezinkundla ezingaphansi, nokusebenza kwezinhlobo ezikhulu zokulungisa ubuhlungu kuzoba yisidingo sokuthinta kwezinhlobo ezikhulu zepolycarbonate. Kepha, kusilelwa isiphakade esikhulu sezinhlobo ezikhulu zepolycarbonate, njengokuthinta kwezinhlobo zokubona nokuthinta kwezinhlobo zokulungisa ubuhlungu, okuyabeka indawo enkulu yokuprodukha kwezinhlobo zaseNingizimu Afrika. Okwamanje, umnotho wasezindaweni wathola isimo sokuthi "kukhona ukuthinta kakhulu kwezinhlobo ezingaphansi futhi kukhona ukungathinta kwezinhlobo ezikhulu", futhi ukuthintana okuhlanganisa izinhlobo zokuthinta kunezinhlobo ezihlukene kuzoba yindlela eyinkulu yokuthola isiphumo ngokuvamile.

Abakhulisi besebenzi bababize ukuthi emva kwalokho, indistri yayozimela kwezinyathelo zokuzilungisa izinto ezihle kanye nokuphutha kwemisebenzi yokuwasha okuhle, futhi yayozidelela kubuyisela kwezinto ezingaphansi. Ngokufika kwemisebenzi yezindlela zokusebenza, isikhundla sepolycarbonate saseChina sibonakala singayizwa ngokugcina ukuthi sifikelela kumazwi amaningi okuhle kanye nokuba yindistri eyodwa kwezinye zomhlaba.
