．．Uruhande rutanga: ubushobozi bushya bwo gukora mu gihugu cyangwa guhindura uburyo bwo gutanga isoko

Uhereye ku isoko rya nylon kwisi yose, nylon 6 na nylon 66 bingana na 95% byubushobozi bwose nibisohoka.Raporo ya IHS ivuga ko muri 2020 isi yose nylon ifite ubushobozi bwa toni miliyoni 10.52 / umwaka, nylon 66 ubushobozi bwa toni miliyoni 3.17 / umwaka.Nilon yo mu gihugu imbere kubera ko caprolactam yibikoresho fatizo byashyizwe mu karere, ubwiyongere bwihuse bw’ubushobozi bw’umusaruro mu myaka icumi ishize, umusaruro wa nylon 6 w’imbere mu 2020 wageze kuri toni miliyoni 6.47 / umwaka, bingana na 62% by’ubushobozi bw’umusaruro ku isi, ubushobozi bwo kubyaza umusaruro ibigo cumi na bibiri bya mbere bingana na 36%, ahanini byibanze mu Bushinwa bwi Burasirazuba, Ubushinwa bw’Amajyepfo n’utundi turere twateye imbere.Dukurikije imibare y’imiti ya Hua'an, mu gihe kiri imbere hazaba toni miliyoni 2.78 z’ubushobozi bushya bwo gukora.Kugeza ubu, nylon 6 yo mu gihugu itanga cyane cyane ibikoresho bya fibre, ejo hazaza hamwe no kwagura ubushobozi bw’umusaruro byatumye habaho irushanwa rikomeye, abayikora benshi bazagira uruhare muri plastiki y’ubuhanga n’ahandi hongerewe agaciro.

Ubushobozi bwa nylon 66 butwarwa nubwa nylon 6. Kugeza ubu, umusaruro wimbere mu gihugu wa nylon 66 hafi toni 600.000 / mwaka, bitewe ahanini na synthesis ya imwe muri monomer adipamide ibikoresho fatizo adiponitrile monopole ndende mumaboko ya a abanyamahanga bake.Mu myaka yashize, aho iterambere rya adiponitrile rigeze, biteganijwe ko umusaruro wiyongera vuba, igenamigambi ririho kandi ryubakwa nylon 66 y’umusaruro wa toni miliyoni 1.26 ku mwaka.

二．Uruhande rusabwa: Ubushinwa bushobora kuzamuka mu isoko

Bitewe na kamere ya nylon 6 na nylon 66 itandukaniro, nylon 6 na nylon 66 ibisabwa biratandukanye.71% ya nylon 6 kumyenda yimyenda, inganda zinganda nizindi fibre fibre, 29% kubisiga.Mugihe 59% ya nylon 66 ikoreshwa mububiko bwa injeniyeri.Mu bihe biri imbere, hamwe n’iterambere ryinshi muri plastiki, byagereranijwe ko nylon 66 na nylon 6 bizakoreshwa mu buhanga bw’ubuhanga.

Usibye isoko ry’isoko rya nylon mu Bushinwa, uhereye ku bindi bihugu byo ku isi nylon 6 na nylon 66 bikoreshwa, hafi imyaka itandatu yo ku isi yose nylon 6 ikoreshwa muri toni miliyoni 2,5 / umwaka hejuru no hasi, ikoreshwa rya nylon 66 muri toni miliyoni 1.5 / ihindagurika ry’umwaka. , ahazaza hateganijwe nyuma yo gukira icyorezo cy’icyorezo kizagira urwego runaka rwo kongera kwiyongera, ariko kubera igiciro kiriho cya nylon mu bihugu byateye imbere mu mahanga ku kigero cyo kwinjira cyabaye kinini, icyerekezo kirekire cyo kuzamuka gahoro, ejo hazaza gukura Gusaba kureba Ubushinwa.

Ugereranije n’imikorere yisoko ryisi yose, Ubushinwa isoko rya nylon ryihuta ryihuta.Kuva mu 2015 kugeza 2019, nylon 6 ikoreshwa ryiyongereyeho toni miliyoni 1.08 / umwaka, aho impuzandengo y’ubwiyongere bw’umwaka wa 9.7%, nubwo icyorezo cyagize ingaruka ku cyifuzo muri 2020, ibicuruzwa byagabanutseho 4.4% gusa (9,6% ku isi yose) ;murwego rumwe, nylon 66 ikoreshwa ryiyongereyeho toni 44.000 / mwaka, ubwinshi ugereranije nubwiyongere mu tundi turere twose twisi.Hamwe n’iyongera ry’ubushobozi bw’ibikoresho fatizo, kugabanya ibiciro, ndetse no kuzamura imibereho y’abaturage no gukenera ibicuruzwa byiza, imyaka icumi iri imbere biteganijwe ko izagira iterambere ryinshi mu ikoreshwa ry’imbere mu gihugu rya nylon 6 na nylon 66 .
