Ibiciro byisoko ryimiti byakomeje kugabanuka mugihe cyigice cyumwaka.Uku kugabanuka kumara igihe kirekire, mugihe ibiciro bya peteroli bikomeje kuba hejuru, byatumye habaho ubusumbane mu gaciro k’amasano menshi mu ruganda rukora imiti.Uko amaherere menshi murwego rwinganda, niko igitutu cyinshi cyigiciro cyurunigi rwinganda.Kubwibyo, ibicuruzwa byinshi byimiti kuri ubu biri mubihe bihendutse ariko bidindiza isoko ryabaguzi, bigatuma ubukungu bwumusaruro muke wibicuruzwa byinshi byimiti.
Igiciro cyisoko rya vinyl acetate nacyo cyakomeje kugabanuka.Mu myaka yashize, igiciro cy’isoko rya vinyl acetate cyamanutse kiva kuri 14862 yu / toni muri Kamena 2022 kugeza muri Kamena 2023, gikomeza kugabanuka hafi umwaka, aho igiciro cyo hasi cyamanutse kigera kuri 5990 yu / toni.Urebye uko ibiciro byifashe mumyaka mike ishize, igiciro cyo hasi mumateka cyagaragaye muri Mata 2020, igiciro cyo hasi cyagaragaye kuri 5115 yuan / toni, igiciro kinini cyagaragaye mu Gushyingo 2021, naho igiciro kinini cyagaragaye kuri 16727 Yuan / toni.

Nubwo igiciro cya vinyl acetate cyagabanutse umwaka ukurikiranye, inyungu yumusaruro wa vinyl acetate ikomeza kuba hejuru kandi ubukungu bwumusaruro ni bwiza.Kuki vinyl acetate ishobora gukomeza urwego rwo hejuru rwiterambere?
Uburyo butandukanye bwo gukora kuri vinyl acetate bivamo inyungu nigihombo gitandukanye
Ukurikije ihinduka ry’inyungu ya vinyl acetate ikorwa nuburyo bwa Ethylene, igipimo cy’inyungu cya vinyl acetate yakozwe nuburyo bwa Ethylene cyahoze mu buryo bwunguka mu myaka mike ishize, inyungu nyinshi yageze kuri 50% cyangwa irenga, ikigereranyo cy'inyungu ni 15%.Birashobora kugaragara ko vinyl acetate ishingiye kuri Ethylene yabaye igicuruzwa cyunguka cyane mumyaka ibiri ishize, hamwe niterambere ryiza muri rusange hamwe ninyungu ihamye.

Urebye uburyo bwa calcium carbide uburyo bwa vinyl acetate, mumyaka ibiri ishize, usibye inyungu nini kuva muri Werurwe 2022 kugeza Nyakanga 2022, ibindi bihe byose byari mubihombo.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%.Birashobora kugaragara ko iterambere ryuburyo bwa calcium karbide ya vinyl acetate ikennye, kandi ibintu muri rusange byerekana igihombo.

Birashobora kugaragara ko atari ibintu bisanzwe kuri vinyl acetate kuba kurwego rwinyungu nyinshi.Gusa uburyo bwa Ethylene bwo gukora vinyl acetate kuri ubu bumeze neza, mugihe uburyo bwa karbide burigihe bwabaye mubihombo mumyaka mike ishize.
Isesengura ryo gukomeza inyungu nyinshi yumusaruro wa vinyl acetate
1. Umubare wibiciro fatizo uratandukanye mubikorwa bitandukanye.Mu musaruro wa vinyl acetate ya Ethylene, ikoreshwa rya Ethylene ni 0.35 naho ikoreshwa rya acide glacial acetike ni 0,72.Ukurikije igipimo mpuzandengo cy’ibiciro muri Kamena 2023, igipimo cya Ethylene mu musaruro wa vinyl acetate ishingiye kuri Ethylene kigera kuri 37%, mu gihe aside aside yo mu kirere ni 45%.Kubwibyo rero, ihindagurika ryibiciro bya acide glacial acetique igira ingaruka zikomeye kumihindagurikire yikiguzi cyumusemburo wa vinyl acetate ushingiye kuri Ethylene, ugakurikirwa na Ethylene.
Kubijyanye nigiciro cyuburyo bwa calcium ya karbide ya vinyl acetate, kariside ya calcium ihwanye na 47% byigiciro cyuburyo bwa calcium karbide ya vinyl acetate, na acide glacial acetike ya glacial ihwanye na 35% byuburyo bwa calcium karbide ya vinyl acetate.Kubwibyo, muburyo bwa calcium karbide ya vinyl acetate, ihinduka ryibiciro bya kariside ya calcium igira ingaruka zikomeye kubiciro, bitandukanye cyane ningaruka ziterwa nuburyo bwa Ethylene.
Kugabanuka gukabije kwibikoresho fatizo Ethylene na acide glacial acetic byatumye igabanuka rikabije ryibiciro.Nk’uko imibare ifatika ibigaragaza, mu mwaka ushize, igiciro cya CFR Amajyaruguru y’Amajyaruguru ya Aziya Ethylene yagabanutseho 33%, naho igiciro cya acide acetique glacial cyaragabanutseho 32%.Nyamara, igiciro cyumusaruro wa vinyl acetate ukoresheje uburyo bwa calcium karbide uburyo bugarukira cyane kubiciro bya kariside ya calcium.Umwaka ushize, igiciro cya kariside ya calcium cyaragabanutseho 25%.
Kubwibyo, ukurikije uburyo bubiri butandukanye bwo kubyaza umusaruro, ibiciro fatizo byuburyo bwa Ethylene vinyl acetate byagabanutse cyane, kandi kugabanya ibiciro ni byinshi kuruta uburyo bwa calcium karbide.

3. Nubwo igiciro cya vinyl acetate cyaragabanutse, kugabanuka ntabwo ari ngombwa nkindi miti.Mu mwaka ushize, igiciro cya vinyl acetate cyaragabanutseho 59%, bigaragara ko cyagabanutse cyane, ariko igiciro cy’indi miti cyaragabanutse cyane.
Vinyl acetate yamye nantaryo yagumanye inyungu runaka, ahanini bitewe nigabanuka ryibiciro ryatewe nigabanuka ryibiciro fatizo, aho gushyigikirwa nisoko ryabaguzi kubiciro byaryo.Nibindi bihe byogukwirakwiza agaciro murwego rwa vinyl acetate.Urebye uko isoko ry’imiti mu Bushinwa rimeze muri iki gihe mu gihe gito, biragoye guhindura byimazeyo imiterere y’isoko ry’imiti mu Bushinwa idafite politiki nini yo gukangurira isoko ry’abaguzi.Biteganijwe ko urunigi rw’agaciro rwa vinyl acetate ruzakomeza kugumana uburyo bwo kohereza ibintu hasi, kandi biteganijwe ko inyungu y’umusaruro ku isoko ry’umuguzi uzaza, cyane cyane ku bicuruzwa bya polyethylene na EV, bizakomeza kubungabungwa inyungu za vinyl acetate.
