Ibiciro byisoko rya shimi byakomeje kugabanuka hafi igice cyumwaka. Kugabanuka igihe kirekire, mugihe ibiciro bya peteroli biguma hejuru, byatumye ubusumbane mu gaciro k'amahuza menshi mu rubavu rw'inganda. Ibindi byinshi mu ruhererekane rw'inganda, niko igitutu kiri ku giciro cy'umunyururu w'inganda. Kubwibyo, ibicuruzwa byinshi byimiti kuri ubu biri muburyo burenze urugero ariko isoko ryabaguzi, bikaviramo ubukungu bwisaruro mubiro byimiti byinshi.
Igiciro cyisoko cya vinyl acetate nacyo cyakomeje kugabanuka. Mu myaka yashize, igiciro cy'isoko cya vinyl acetate cyavuye mu 14862 yavuye mu 14862 yavuye muri Kamena 2022 kugeza 2023, akomeza kugabanuka ku mwaka umwe, hamwe nigiciro gito cyo guta kuri 5990 Yuan / toni. Kuva ku giciro cy'ibiciro mu myaka mike ishize, igiciro gito mu mateka cyagaragaye muri Mata 2020, igiciro cyo hasi cyagaragaye kuri 5115 yuan / toni, igiciro cyo hejuru cyagaragaye mu Gushyingo 2027 Yuan / toni.

Nubwo igiciro cya vinyl acetate cyagabanutseho umwaka ukurikiranye, inyungu yumutekano wa vinyl acetate akomeje kuba ndende kandi ubukungu bwumwanda ni bwiza. Kuki vinyl acetate ishobora gukomeza gutera imbere?
Ibikorwa bitandukanye bya Imivugo kuri Vinyl Acetate ibisubizo muburyo butandukanye nigihombo
Dukurikije impinduka zikoreshwa rya vinyl acetate yakozwe na Ethylene yakozwe na Ethylene, umubare winyungu wa vinyl acetate wahozeho nuburyo bwunguka buri gihe mumyaka mike ishize, igipimo cyihariye cyinyungu cyageze kuri 50% cyangwa birenga, hamwe nibigereranyo byinyungu ni 15%. Birashobora kugaragara ko Etylene ishingiye kuri vinyl acetate yabaye ibicuruzwa byunguka byuzuye mumyaka ibiri ishize, hamwe niterambere ryinshi rusange hamwe nimpande zihamye.

Dukurikije uburyo bwa Calcium Carbide Dinyl Acetate, mu myaka ibiri ishize, usibye inyungu zikomeye kuva 20 Werurwe2 kugeza 2022, ibindi bihe byose byabuze. Kugeza ku ya 2023 Kamena3, urwego rwinyungu rwa Calcium Carbide ya Vinyl Acetate yari afite igihombo cya 20%, hamwe na maringi ya Calcium ya Calcium Carbide Mu myaka ibiri ishize yari 0.2%. Birashobora kugaragara ko gutera imbere muburyo bwa Calcium kuri vinyl acetate ari abakene, kandi ibintu rusange byerekana igihombo.

Birashobora kugaragara ko atari ibintu bisanzwe kuri vinyl acetate kuba kurwego rwinyungu nyinshi. Gusa uburyo bwa Royylene ya Vinyl Acetate Umusaruro wunguka kuri ubu, mugihe uburyo bwa karbide bwamye bwagiye mumyaka mike ishize.
Isesengura ryo gukomeza inyungu nyinshi za Ethylene ishingiye kuri Vinyl Acetate Umusaruro
1. Igipimo cyibikoresho bya fatizo biratandukanye muburyo butandukanye. Muri Ethylee gushingira kuri vinyl acetate umusaruro, ukoresheje igice cya Ethylene ni 0.35 nigice cyo gukoresha acide yinda ni 0.72. Dukurikije impuzandengo y'ibiciro muri Kamena 2023, umubare wa Ethylene muri Ethyle ushingiye kuri 37%, mugihe acide yinda yica ni 45%. Kubwibyo, ibiciro byamazi ya acide yinda bigize ingaruka zikomeye ku guhindura ibintu bya Etylene bishingiye kuri Vinyl acetate, akurikirwa na Ethyne.
Naho ikiguzi cya Calcium Carbide kuri vinyl acetate, karabuum carbide igera kuri 47% yuburyo bwa Calcium Kubwibyo, muri Calcium CarBem ya Vinyl Acetate, impinduka ziri mugiciro cya Calcium Carbide ifite ingaruka zikomeye kubiciro, bitandukana cyane ningaruka zabigenewe.
2. Kugabanuka kwinshi mubikoresho fatizo Ethylene na acide yita acetike byatumye habaho kugabanuka gukabije. Nk'uko amakuru abitangaza, mu mwaka ushize, igiciro cya CFR y'Amajyaruguru ya Aziya Ethylene cyagabanutseho 33%, kandi igiciro cya acide kitarangwa cya acetike cyagabanutseho 32%. Nyamara, igiciro cya serivisi cya vinyl acetate ukoresheje uburyo bwa calcium carbide ahanini bigarukira ku giciro cya calcium carbide. Mu mwaka ushize, igiciro cya Carcium Carbide cyagabanutseho 25%.
Kubwibyo, ukurikije uko ibintu bibiri bitandukanye binyuranye, ibikoresho bifatika bya Ethyle Metlex uburyo bwagabanutse cyane, kandi kugabanya ibiciro birarenze ibyo muburyo bwa Calcium Carbide.

3. Nubwo igiciro cya vinyl acetate cyagabanutse, kugabanuka ntabwo ari ngombwa nkindi miti. Mu mwaka ushize, igiciro cya vinyl acetate cyagabanutseho 59%, bigaragara ko gigabanuka cyane, ariko igiciro cyindi miti cyagabanutse cyane.
Vinyl Acetate yahoraga akomeza inyungu runaka, ahanini biterwa no kugabanya ibiciro biterwa no kugabanuka kwibiciro fatizo, aho gushyigikira isoko ry'abaguzi ku biciro byayo. Ibi kandi nikibazo cyo kwanduza agaciro mumirongo ya Vinyl Acetate. Duhereye ku isoko rya shimi rya chemique mu Bushinwa mu gihe gito, biragoye cyane guhindura imiti idakomeye y'isoko ry'imiti y'Abashinwa nta politiki y'abaguzi bakomeye. Biteganijwe ko urunigi rwagaciro rwa vinyl acetate ruzakomeza gukomeza logique yo hepfo, kandi biteganijwe ko inyungu zasangwa nisoko ryigiheza, cyane cyane kubicuruzwa bya polyethylene, cyane cyane ibicuruzwa bya polyethylene nibicuruzwa, bizakomeza kugabanuka kwa vinyl acetate.
