Byagaragaye ko ibiciro byibicuruzwa bivura imiti ku isoko bikomeje kugabanuka, bigatuma habaho ubusumbane bw’agaciro mu masano menshi y’uruganda rukora imiti.Ibiciro bya peteroli bihoraho byongereye umuvuduko wibiciro ku ruganda rukora imiti, kandi ubukungu bw’umusaruro w’ibicuruzwa byinshi bikomoka ku miti ni bibi.Nyamara, igiciro cyisoko rya vinyl acetate nacyo cyagabanutse cyane, ariko inyungu yumusaruro yagumye hejuru kandi ubukungu bwumusaruro ni bwiza.None, kubera ikivinyl acetateisoko ikomeza urwego rwo hejuru rwiterambere?

Kuva hagati kugeza mu mpera za Kamena 2023, igiciro cy isoko rya vinyl acetate ni 6400 yuan / toni.Ukurikije igiciro cyibikoresho fatizo byuburyo bwa Ethylene nuburyo bwa calcium karbide, inyungu yinyungu yuburyo bwa Ethylene vinyl acetate igera kuri 14%, mugihe inyungu yinyungu yuburyo bwa calcium carbide uburyo vinyl acetate iri mubihombo.Nubwo igabanuka rya vinyl acetate ikomeje kumara umwaka, inyungu yinyungu ya vinyl acetate ishingiye kuri Ethylene ikomeza kuba hejuru cyane, igera kuri 47% mubihe bimwe na bimwe, iba ibicuruzwa byunguka byinshi mumiti myinshi.Ibinyuranye, uburyo bwa calcium karbide ya vinyl acetate yabaye mubihombo mumyaka hafi ibiri ishize.

Iyo usesenguye impinduka zinyungu zinyungu za Ethylene zishingiye kuri vinyl acetate na calcium karbide ishingiye kuri vinyl acetate, usanga vinyl acetate ishingiye kuri Ethylene yamye yunguka mumyaka mike ishize, hamwe ninyungu nyinshi igera kuri 50% cyangwa hejuru kandi ugereranije urwego rwinyungu zingana na 15%.Ibi byerekana ko vinyl acetate ishingiye kuri Ethylene yungutse cyane mumyaka ibiri ishize, hamwe niterambere ryiza muri rusange hamwe ninyungu ihamye.Mu myaka ibiri ishize, usibye inyungu zikomeye kuva muri Werurwe 2022 kugeza Nyakanga 2022, uburyo bwa calcium karbide ya vinyl acetate yabaye mubihombo mubindi bihe byose.Kugeza muri Kamena 2023, urwego rwinyungu rwuburyo bwa calcium carbide uburyo bwa vinyl acetate bwari igihombo cya 20%, naho impuzandengo yinyungu yuburyo bwa calcium carbide uburyo bwa vinyl acetate mumyaka ibiri ishize yari igihombo 0.2%.Duhereye kuri ibi, birashobora kugaragara ko iterambere ryuburyo bwa calcium karbide ya vinyl acetate ikennye, kandi muri rusange ibintu byerekana igihombo.

Binyuze mu isesengura rindi, impamvu nyamukuru zituma inyungu nyinshi ziva mu musaruro wa vinyl acetate zishingiye kuri Ethylene ni izi zikurikira: icya mbere, igipimo cy’ibiciro fatizo mu bicuruzwa bitandukanye kiratandukanye.Muburyo bwa Ethylene ya vinyl acetate, ikoreshwa rya Ethylene ni 0.35, naho ikoreshwa rya acide glacial acetike ni 0,72.Ukurikije igipimo mpuzandengo cy’ibiciro muri Kamena 2023, Ethylene igera kuri 37% y’igiciro cya vinyl acetate ishingiye kuri Ethylene, mu gihe acide glacial acetic glacial igera kuri 45%.Kubwibyo rero, kugirango ingaruka zigiciro, ihindagurika ryibiciro bya acide glacial acetique igira ingaruka zikomeye kumihindagurikire yikiguzi cya vinyl acetate ishingiye kuri Ethylene, ikurikirwa na Ethylene.Ku bijyanye n'ingaruka ku giciro cya calcium carbide uburyo bwa vinyl acetate, ikiguzi cya calcium karbide ya calcium carbide uburyo bwa vinyl acetate igera kuri 47%, naho ikiguzi cya acide glacial acetic acide ya calcium carbide uburyo bwa vinyl acetate igera kuri 35% .Kubwibyo, muburyo bwa calcium karbide ya vinyl acetate, ihinduka ryibiciro bya kariside ya calcium igira ingaruka zikomeye kubiciro.Ibi bitandukanye cyane nibiciro byuburyo bwa Ethylene.

Icya kabiri, igabanuka ryibikoresho fatizo Ethylene na acide glacial acetique byari bikomeye, bituma igabanuka rikabije ryibiciro.Mu mwaka ushize, igiciro cya CFR Amajyaruguru y’Amajyaruguru ya Aziya Ethylene yagabanutseho 33%, naho igiciro cya acide glacial acetic glacial cyaragabanutseho 32%.Nyamara, igiciro cya vinyl acetate ikorwa nuburyo bwa calcium karbide ikoreshwa cyane cyane nigiciro cya kariside ya calcium.Mu mwaka ushize, igiciro cya kariside ya calcium yagabanutse ku gipimo cya 25%.Kubwibyo, ukurikije uburyo bubiri butandukanye bwo gukora, igiciro fatizo cya vinyl acetate yakozwe nuburyo bwa Ethylene cyaragabanutse cyane, kandi kugabanya ibiciro ni byinshi kuruta uburyo bwa calcium karbide.

Nubwo igiciro cya vinyl acetate cyaragabanutse, kugabanuka kwayo ntigaragara nkindi miti.Dukurikije imibare, mu mwaka ushize, igiciro cya vinyl acetate cyagabanutseho 59%, ibyo bikaba bisa nkaho ari ngombwa, ariko indi miti yagiye igabanuka cyane.Muri iki gihe intege nke z’isoko ry’imiti mu Bushinwa ziragoye guhinduka.Biteganijwe ko mu gihe kiri imbere, bishoboka cyane ko inyungu z’umusaruro w’isoko ry’umuguzi wa nyuma, cyane cyane ibicuruzwa nka alcool ya polyvinyl na EVA, bizakomeza kubungabungwa inyungu za vinyl acetate.

Hariho ubusumbane bukomeye mu ruhererekane rw’inganda zikora imiti, kandi ibicuruzwa byinshi biri mu giciro cyinshi ariko isoko ry’abaguzi ridindira, bigatuma ubukungu bw’umusaruro bubi.Nubwo, nubwo byahuye ningorane, isoko rya vinyl acetate ryagumanye urwego rwo hejuru rwunguka, bitewe ahanini nigipimo gitandukanye cyibiciro fatizo mubikorwa byacyo no kugabanya ibiciro byatewe no kugabanuka kwibiciro fatizo.Nyamara, imiterere idahwitse yisoko ryimiti yubushinwa iragoye guhinduka muburyo bukomeye.Biteganijwe ko mu gihe kiri imbere, bishoboka cyane ko inyungu z’umusaruro w’isoko ry’umuguzi wa nyuma, cyane cyane ibicuruzwa nka alcool ya polyvinyl na EVA, bizakomeza kubungabungwa inyungu za vinyl acetate.
