1 、Inzira yo gukomeza kwiyongera mubushobozi bwa MMA

Mu myaka yashize, ubushobozi bw’umusaruro wa MMA (methyl methacrylate) mu Bushinwa bwerekanye ko bwiyongereye cyane, buva kuri toni miliyoni 1.1 muri 2018 bugera kuri toni miliyoni 2.615 muri iki gihe, ubwiyongere bwikubye hafi 2,4. Iri terambere ryihuse riterwa ahanini niterambere ryihuse ryinganda zikora imiti mu gihugu no kwagura isoko. By'umwihariko mu 2022, umuvuduko w’ubwiyongere bw’ubushobozi bw’imbere mu gihugu MMA wageze kuri 35.24%, kandi ibikoresho 6 byashyizwe mu bikorwa mu mwaka, bikomeza guteza imbere umuvuduko w’ubushobozi bw’umusaruro.

2 、Isesengura ryitandukaniro ryubwiyongere bwubushobozi hagati yuburyo bubiri

Urebye uburyo bwo kubyaza umusaruro, hari itandukaniro rikomeye mubipimo byiyongera byubushobozi hagati yuburyo bwa ACH (uburyo bwa acetone cyanohydrin) nuburyo bwa C4 (uburyo bwa okiside ya isobutene). Iterambere ryubushobozi bwuburyo bwa ACH ryerekana kwiyongera, mugihe umuvuduko wubwiyongere bwuburyo bwa C4 bwerekana kugabanuka. Iri tandukaniro riterwa ahanini ningaruka ziterwa nibiciro. Kuva mu 2021, inyungu z'umusaruro wa C4 MMA zakomeje kugabanuka, kandi igihombo gikomeye cyabaye kuva 2022 kugeza 2023, impuzandengo yumwaka inyungu ihwanye na Yuan 2000 kuri toni. Ibi bidindiza mu buryo butaziguye umusaruro wa MMA ukoresheje inzira ya C4. Ibinyuranye, inyungu yinyungu yumusaruro wa MMA muburyo bwa ACH iracyemewe, kandi kwiyongera kumusaruro wa acrylonitrile wo hejuru utanga garanti yibikoresho bihagije kuburyo bwa ACH. Kubwibyo, mumyaka yashize, MMA nyinshi yakozwe nuburyo bwa ACH iremewe.

3 、Isesengura ryibikoresho byo hejuru no kumanuka byunganira ibikoresho

Mu nganda zitanga umusaruro wa MMA, igipimo cy’inganda zikoresha uburyo bwa ACH kiri hejuru cyane, kigera kuri 13, mu gihe hari imishinga 7 ikoresha uburyo bwa C4. Uhereye kumiterere yimbere yibikoresho bifasha, ibigo 5 gusa nibyo bitanga PMMA, bingana na 25%. Ibi byerekana ko ibikoresho byo hasi byunganira MMA inganda zitanga umusaruro bitaragera neza. Mu bihe biri imbere, hamwe no kwagura no guhuriza hamwe urwego rw’inganda, biteganijwe ko umubare w’inganda zishyigikira ibicuruzwa biva mu mahanga byiyongera.

4 、Imiterere yimbere yuburyo bwa ACH nuburyo bwa C4 buhuye

Mu nganda zitanga umusaruro wa ACH MMA, 30.77% zifite ibikoresho byo hejuru bya acetone, naho 69.23% bifite ibikoresho bya acrylonitrile yo hejuru. Bitewe nuko hydrogène cyanide mu bikoresho fatizo byakozwe nuburyo bwa ACH ituruka cyane cyane ku kongera umusaruro wa acrylonitrile, gutangiza MMA hakoreshejwe uburyo bwa ACH ahanini bigira ingaruka ku itangizwa ry’uruganda rwa acrylonitrile rushyigikiwe, mu gihe ibiciro byatewe ahanini n’igiciro cy’ibikoresho fatizo bya acetone. Ibinyuranye, mubigo bitanga umusaruro MMA ukoresheje uburyo bwa C4, 57.14% bafite ibikoresho byo hejuru isobutene / tert butanol. Ariko, kubera impamvu zidasanzwe, ibigo bibiri byahagaritse ibice bya MMA kuva 2022.

5 、Guhindura igipimo cyo gukoresha ubushobozi bwinganda

Hamwe n'ubwiyongere bwihuse bwibicuruzwa bya MMA hamwe nubwiyongere bukabije bwibisabwa, inganda zitangwa ninganda zigenda zigenda ziva mubuke bwibicuruzwa bikaboneka. Iri hinduka ryatumye habaho umuvuduko muke ku mikorere y’inganda zo mu rugo MMA, kandi igipimo rusange cy’ubushobozi bw’inganda cyerekanye ko cyamanutse. Mu bihe biri imbere, hamwe no gusohora buhoro buhoro ibyifuzo bikenerwa no guteza imbere urwego rw’inganda, biteganijwe ko imikoreshereze y’ubushobozi bw’inganda itezwa imbere.

6 、Ibihe bizaza ku isoko

Urebye imbere, isoko rya MMA rizahura nibibazo byinshi n'amahirwe. Ku ruhande rumwe, ibihangange byinshi by’imiti ku isi byatangaje ko byahinduye ubushobozi ku bihingwa byabo bya MMA, bizagira ingaruka ku itangwa n’ibisabwa ku isoko rya MMA ku isi.
