Mu 2022, Ubushinwa butanga umusaruro wa Ethylene bwageze kuri toni miliyoni 49.33, burenga Amerika, bukaba butanga umusaruro mwinshi ku isi, Ethylene yafatwaga nk'ikimenyetso cy'ingenzi kigaragaza umusaruro w’inganda zikora imiti. Biteganijwe ko mu 2025, Ubushinwa butanga umusaruro wa Ethylene uzarenga toni miliyoni 70, ibyo bikaba ahanini bizahaza ibyifuzo by’imbere mu gihugu, ndetse n’ikirenga.

Inganda za Ethylene nizo nkingi y’inganda zikomoka kuri peteroli, kandi ibicuruzwa byayo bingana na 75% by’ibicuruzwa bikomoka kuri peteroli kandi bifite umwanya ukomeye mu bukungu bw’igihugu.

Ethylene, propylene, butadiene, acetylene, benzene, toluene, xylene, okiside ya Ethylene, Ethylene glycol, nibindi. Byakozwe nibihingwa bya Ethylene, nibikoresho fatizo byibanze byingufu nshya nimirima mishya. Byongeye kandi, igiciro cyumusaruro wa Ethylene wakozwe ninganda nini zihuriweho gutunganya no gutunganya imiti ni mike. Ugereranije n’inganda zitunganya inganda zingana, agaciro kongerewe ibicuruzwa biva mu nganda zikora inganda n’inganda zishobora kwiyongeraho 25% naho gukoresha ingufu birashobora kugabanuka hafi 15%.

Polyakarubone, itandukanya bateri ya lithium, EVV ifotora (Ethylene - vinyl acetate copolymer) irashobora gukorwa muri Ethylene, alpha olefin, POE (polyolefin elastomer), karubone, DMC (dimethyl carbone), uburemere bwa molekile ya polyethylene (UHMWPE) nibindi bicuruzwa bishya. Dukurikije imibare, hari ubwoko 18 bwibicuruzwa bya etilene kumanuka bijyanye ningufu nshya, ibikoresho bishya nizindi nganda zumuyaga. Bitewe niterambere ryihuse ryingufu nshya ninganda nshya nkibinyabiziga bishya byingufu, Photovoltaque na semiconductor, ibyifuzo byibikoresho bishya biriyongera.

Ethylene, nkibyingenzi byinganda zikomoka kuri peteroli, irashobora kuba irenga, ibyo bikaba byerekana inganda za peteroli zihura noguhindura no gutandukana. Ntabwo ibigo byapiganwa gusa bivanaho imishinga yasigaye inyuma, ubushobozi bwateye imbere bukuraho ubushobozi bwinyuma, ariko kandi gusenyuka no kuvuka kwinganda zikomeye za Ethylene kumasoko yinganda zinganda.

Ibigo bikuru birashobora kuvugurura

Ethylene irashobora kuba isagutse, igahatira gutunganya no gutunganya imiti ikomeza kwuzuza urunigi, kwagura urunigi no gushimangira urunigi kugirango irushanwe kurwego. Guhera kuri peteroli, birakenewe kubaka inyungu yibanze yo kwishyira hamwe. Igihe cyose hari isoko cyangwa ibicuruzwa bifite ubushobozi bwisoko runaka, hazashyirwaho umurongo, ibyo kandi byihutisha kurandura abatsinze nabatsinzwe muruganda rwose rwa shimi. Umusaruro nuburyo bwibicuruzwa byinshi byimiti nibicuruzwa byiza bya shimi bizana impinduka. Ubwoko bw'umusaruro n'ibipimo bizagenda byiyongera, kandi umubare w'inganda uzagabanuka buhoro buhoro.

Ibikoresho by'itumanaho, terefone ngendanwa, ibikoresho byambarwa hamwe n’ibindi bikoresho bya elegitoroniki y’abaguzi, ubwenge bw’imodoka, ibikoresho by’ibikoresho byo mu rugo biratera imbere byihuse, bigatuma ubwiyongere bwihuse bukenerwa ku bikoresho bishya bya shimi. Ibi bikoresho bishya bya chimique hamwe na monomer iyobora imishinga ifite iterambere ryihuta bizagenda byihuta, nkingufu 18 nshya nibicuruzwa bishya munsi ya Ethylene.

Umuyobozi wa Hengli Petrochemicals, Fan Hongwei, yavuze ko uburyo bwo gukomeza inyungu zikomeye zo guhatanira amasoko no gushakisha inyungu nyinshi mu rwego rw’ibikorwa byose by’inganda ari ikibazo kigomba kwibandwaho. Tugomba guha umwanya wuzuye ibyiza byurwego rwo hejuru rwinganda, kwagura no kunoza urwego rwinganda ruzenguruka ibicuruzwa byo hasi kugirango dushyireho inyungu nshya zo guhatanira, kandi duharanire guteza imbere kwaguka kwaguka kwibicuruzwa byo hasi kugirango twubake urunigi rukora inganda.

Kang Hui New Material, ishami rya Hengli Petrochemical, irashobora gukora 12 micron silicon irekura firime yo gukingira batiri ya lithium ikingira kumurongo, Hengli Petrochemical irashobora gutanga ibicuruzwa byinshi 5DFDY, kandi MLCC yayo isohora firime yibice birenga 65% byumusaruro wimbere mu gihugu.

Dufashe gutunganya no guhuza imiti nkurubuga rwo kwaguka mu buryo butambitse kandi buhagaritse, twaguka kandi dushimangira uturere twinshi kandi dushiraho iterambere ryuzuye ryibice. Isosiyete imaze kwinjira ku isoko, irashobora kwinjira mu mishinga iyoboye. Ibigo 18 byambere byingufu nshya nibicuruzwa bishya munsi ya Ethylene birashobora guhura nimpinduka za nyirubwite bikava kumasoko.

Mubyukuri, guhera muri 2017, Shenghong Petrochemicals yatangije toni 300.000 / mwaka EVA ikoresheje ibyiza byurwego rwose, impera za 2024 zizashyirwa mubikorwa buhoro buhoro toni 750.000 za EVA, zizashyirwa mubikorwa mumwaka wa 2025, icyo gihe, peteroli ya Shenghong izaba isoko ryambere ritanga isoko rya EVA rinini cyane.

Ubushinwa bumaze kwibandaho, umubare wa parike n’inganda mu ntara zikomeye z’imiti bizongera kugabanuka buhoro buhoro, Shandong parike y’imiti irenga 80 izagenda igabanuka kugeza kuri kimwe cya kabiri, Zibo, Dongying n’utundi turere tw’inganda zikora imiti zizakurwaho kimwe cya kabiri. Kuri sosiyete, ntabwo uri mwiza, ariko abanywanyi bawe barakomeye.

Ati: “Biragoye cyane“ kugabanya amavuta no kongera imiti

“Kugabanya peteroli no kongera imiti” byahindutse icyerekezo cyo guhindura peteroli yo mu gihugu n’inganda zikora imiti. Gahunda yo guhindura ibintu muri iki gihe itanga umusaruro wibanze wibikoresho ngengabuzima nka Ethylene, propylene, butadiene, benzene, toluene na xylene. Uhereye ku iterambere rigezweho, Ethylene na propylene biracyafite umwanya wo kwiteza imbere, mu gihe Ethylene ishobora kuba irenze, kandi bizagora cyane "kugabanya amavuta no kongera imiti".

Mbere ya byose, biragoye guhitamo imishinga nibicuruzwa. Ubwa mbere, isoko ryisoko nubushobozi bwisoko biragoye guhitamo ibicuruzwa bifite ikoranabuhanga rikuze. Icya kabiri, hari isoko ryubushobozi hamwe nubushobozi bwisoko, ibicuruzwa bimwe biterwa rwose nibicuruzwa byatumijwe mu mahanga, ntibishobora kumenya ikoranabuhanga ryibikorwa byo mu rwego rwo hejuru, nkibikoresho byo mu rwego rwo hejuru byo mu bwoko bwa resinike, rebero yo mu rwego rwo hejuru, fibre yo mu rwego rwo hejuru, fibre ya karubone yo mu rwego rwo hejuru, plastiki y’ubuhanga, imiti y’ubuhanga bwa elegitoronike, n'ibindi .. Ibyo bicuruzwa byose birashobora guhura n’ikibazo cy’ishoramari, kandi ibyo bicuruzwa byose ntibishobora gutangiza ubushakashatsi.

Inganda zose kugabanya peteroli no kongera imiti, kandi amaherezo biganisha kubushobozi burenze bwibicuruzwa bivura imiti. Mu myaka yashize, umushinga wo gutunganya no gutunganya imiti ihuza cyane cyane ugamije “kugabanya peteroli no kongera chimie”, kandi inganda zisanzwe zitunganya imiti n’imiti nazo zifata “kugabanya peteroli no kongera chimie” nkicyerekezo cyo guhindura no kuzamura. Mu myaka ibiri cyangwa itatu ishize, Ubushinwa bushya bw’imiti bwarenze hafi umubare w’imyaka icumi ishize. Inganda zose zitunganya inganda "zigabanya peteroli no kongera chimie. Nyuma yububasha bwo kubaka ubushobozi bwa chimique, inganda zose zishobora kugira ibyiciro byikirenga cyangwa ibicuruzwa byinshi. Ibikoresho byinshi bishya bya chimique nibicuruzwa byiza bya chimique bifite amasoko mato, kandi mugihe cyose habaye iterambere mubuhanga, hazabaho kwihuta, biganisha ku bushobozi bukabije no gutakaza inyungu, ndetse no mu ntambara yoroheje.
