Nyuma y'Ibirori by'Impeshyi mu 2021, Igiciro cy'ibikoresho by'ibanze cyafashe intera itunguranye, kandi inganda zose zirashimwa.Muri rusange, izamuka ry’ibiciro by’ibanze riterwa no kuzamuka kw’ubukungu bw’Ubushinwa hakiri kare, ibyo bikaba byaratumye habaho kudahuza itangwa n’ibikenerwa n’ibikoresho fatizo by’inganda n’ibicuruzwa;Bitewe n'ingaruka zo kugabanya ubushobozi, Bimwe mubikoresho byibanze bifite ubushobozi budahagije bwo gukora, Ikinyuranyo hagati yibitangwa nibisabwa cyiyongereye, Kandi ihungabana ryibicuruzwa ryatumye ibiciro bizamuka.
Kuzamuka kw'ibikoresho by'ibanze bituma abantu bumva "ubwoba."Amakuru rusange yerekana ko ugereranije nintangiriro za 2020, ibikoresho byibanze byiyongereyeho hejuru ya 200% umwaka ushize, n-butanol yiyongereyeho hejuru ya 167% umwaka ushize, aside acike yiyongereye kurenza 166% umwaka-ku-mwaka, n'inzoga za isooctyl ziyongereyeho hejuru ya 150% umwaka-ku-mwaka.Propane, polymeric MDI, nibindi byazamutse hejuru ya 100% umwaka ushize, naho ibikoresho fatizo nka acetone, TDI, aniline, Ethylene, na isopropanol byazamutse hejuru ya 50% umwaka ushize.Muri rusange, gucukura peteroli na gaze karemano, gutunganya lisansi, gucukura ibyuma no gutunganya ibyuma bya fer, hamwe ninganda zikora fibre fibre biza kumwanya wambere witerambere ryumwaka.
Kuva mu ntangiriro za Werurwe, 1,4-butanediol (BDO), ibikoresho by'ibanze byakoreshwaga mu gukora PBT, yavuzwe kuri 31.500 CNY / Ton;igiciro cya bisphenol A yakoreshejwe mu gukora PC yazamutse igera kuri 24,133.33 CNY / Ton;ishingiro ryo gukora PP Ibikoresho propylene yazamutse igera kuri 8459 CNY / Ton;igiciro mpuzamahanga cya peteroli yibikoresho byibanze bikoreshwa mugukora PVC namavuta yavuye kuri 30 US $ / barrale igera kuri 85 US $ / barrile;igiciro cya epoxy resin, ibikoresho byibanze bikoreshwa mugukora ibisigazwa bya UV-bivura, byazamutse bigera kuri 30100 CNY / Ton;igiciro cyibyuma byakoreshwaga mu gukora imikandara ya plastike-plastike yazamutse igera kuri 5270 CNY / Ton.
Byongeye kandi, igiciro cyisoko rya LLDPE kijyanye no gukata ibikoresho polyethylene (PE) yazamutse igera kuri 8950-9200 CNY / Ton.Igiciro cyibibanza bya LDPE, ikimenyetso kinini cy’iburayi, cyazamutse kigera ku 1.800 euro / Ton;igiciro cyumwotsi muke halogen-polyolefin (EVA) yazamutse igera kuri 21.000-22.000 CNY / Ton;igiciro cyubu cyibirahure fibre yintambara yarenze 6.000 CNY / Ton;6625 CNY / Ton.
Amakuru yavuzwe haruguru yerekana ko igiciro cyibikoresho byibanze bijyanye n’umusaruro wa fibre optique na kabili muri rusange bigenda byiyongera, kandi iyi nzira izamuka izakomeza mu gihe gito.Igiciro cyazamutse cyibikoresho byibanze cyashyizeho igitutu kuri fibre optique n’ibikoresho bikoresha insinga, kandi byazanye igitutu kuri fibre optique hamwe n’amasosiyete akora insinga.Byumvikane ko bitewe n’igitutu cy’izamuka ry’ibiciro by’ibanze, fibre optique n’inganda zikoreshwa mu bikoresho na byo "bizamuka".
