Ibisobanuro bishyushye bya PVC: Uhereye ku nyungu zamateka, guhitamo （2）

2. Inyungu no gutangira -kora -Fata PVC nkurugero

Igishushanyo gikurikira gihitamo PVC ejo hazaza ninyungu zerekana kuva 2016 kugeza ubu.Muri byo, inyungu zatoranije uhagarariye Shandong hanze-ya -Shandong hanze -y -amabuye -yambere hamwe ninyungu ihuriweho.Bitewe nibyiza byumutungo wamakara, igiciro kiri munsi yubushinwa bwuburasirazuba.Biroroshye guhagararira inyungu zinganda zinganda.Kugeza ubu, ubushobozi bwa electrone yo mu gihugu bugera kuri 80%, Ethylene ubushobozi bwa Fondateri bwagize 20%, naho umusaruro wa chlorine wuzuye ni 70%.Kubera ko inyungu za chlorine -alkali zishyizwe hamwe zisumba cyane iz'inyungu z'isosiyete, Ubushinwa bw'Uburasirazuba bukoreshwa cyane cyane mu gukoresha Ubushinwa bw'Iburasirazuba mu bihugu by'amahanga.Inyungu yumushinga wa PVC wamabuye yamashanyarazi nurwego rwo hasi muruganda.Kurugero, isosiyete ya PVC ifite inyungu, noneho inganda zunguka muri rusange.Niba Ubushinwa bwiburasirazuba bwahujwe na PVC bifite igihombo cyinyungu, umusaruro usanzwe winganda urashobora kugira ingaruka.

Urebye kuva 2016 kugeza 2023, igihe inyungu z’amasosiyete y’amashanyarazi hanze y’Ubushinwa yageze ku 1.000, ahanini yaherekejwe n’isonga ry’isoko ryateguwe, nko mu Gushyingo 2016, Nzeri 2017, na Ukwakira 2021. Iyo kwishyira hamwe kwa lyon ari yashizweho, iherekejwe ahanini nu gice cyateguwe, nka Mutarama 2016, Mutarama 2022, na Ugushyingo 2022. Urebye ku bihe by’inganda, PVC ifite ibyokurya bibiri mu mwaka mu mpeshyi no mu gihe cyizuba, guhera muri Mata na Kamena na Nyakanga-Nzeri.Ibyiciro bitatu byambere biri hafi yigihe cyo kubungabunga.Icyiciro cyo gutanga no kutaringaniza icyifuzo cyazanye ibiciro bizamuka.Iyo inyungu zamasosiyete ziyongereye, inganda zazamutse vuba bishoboka.Nyuma yo gutanga ibicuruzwa byiyongereye no kuzuza ibice byububiko byadindije, isoko ryarahagaze.Iyo igihombo cya chlorine -alkali ihuriweho, inganda zaragabanutse mugice.Nubwo nta bugenzuzi busanzwe kuri iki cyiciro, buri ku rwego rwo hasi icyarimwe.Muyandi magambo, kubaka inyungu nugufata ubwoko bwa "V".Iyo igihombo, ubwubatsi "buhindagurika", kandi inyungu ifitanye isano nziza

Kuberako inganda za PVC zahujwe ahanini, ibindi bikoresho bigomba gusuzumwa neza mugihe muganira ku nyungu za PVC.Muri byo, ingaruka nyinshi ni ibicuruzwa byo hejuru hamwe na alkali yibicuruzwa biherekeza.Kugeza ubu, ubushobozi bwo kubyaza umusaruro uburyo bwa Corporal ni bunini cyane, bityo ikiguzi cyamabuye yamashanyarazi na PVC kirahuzwa.Muri rusange, ibiciro bya PVC byazamutse kubiciro byamabuye yamashanyarazi.2021 ni umwaka udasanzwe.Biterwa no gukoresha ingufu zombi.Amashanyarazi make yamashanyarazi arakomeye, kandi igiciro cyamabuye yamashanyarazi cyazamutse.Ku masosiyete akora amashanyarazi ya PVC wenyine, ishyaka-ryo gutangira ni ryinshi.Kuri iki cyiciro, inyungu iboneka cyane cyane muruganda rwa electrone (uruganda rukora amashanyarazi rwigenga rwonyine rushobora kuzuza inyungu ya PVC binyuze mu nyungu yamabuye y'amashanyarazi), kuburyo bishobora kugaragara ko bishobora kugaragara ko bishobora kugaragara ko bishobora kugaragara Nubwo igiciro cya PVC cyakomeje guca igiciro kiri hejuru muri 2021, inyungu zamasosiyete ya PVC yamasosiyete PVC muri rusange iratakaza amafaranga.Iki gice cyikigo cyagabanije cyane umusaruro cyangwa kubungabunga.Mubyongeyeho Igihe kimwe cyigihe kimwe ni gito.

Amabati yo hanze ya Pvc 

Igiciro cya alkali alkali nayo igira ingaruka zikomeye kumyubakire yamasosiyete ya PVC.Mubisanzwe, toni 1 PVC iherekejwe na toni 0.7-0.8 ya alkaline.Inyungu hagati yabo yagize ingaruka kuri mugenzi we.Kugwa, isosiyete ya PVC yamaze gutangira guteza imbere igihombo, ariko muri iki gihe imirimo yinganda ntabwo yagize ingaruka nyinshi.Kugeza muri Nyakanga, igiciro cya alkaline pyrine cyaragabanutse, gitera igihombo cyinyungu ya societe ihuriweho na chlorine na alkali.Isoko rya PVC rizongera kwiyongera.Ugushyingo 2022, alkali alkali yagabanutseho gato, kandi inyungu yuzuye ya chlorine -alkali yatakaje amafaranga.Muri Werurwe, igiciro cya alkaline yokeje cyaragabanutse cyane, kandi igihombo cya chlorine -alkali cyinjijwe cyiyongereye cyane.Mugihe igihe cyo kubungabunga kiri hafi kwinjira, birashobora kugaragara ko igihe cyo gutangira uyu mwaka ari kare ugereranije nimyaka yashize.

Muri rusange, ku nganda zikora imiti, inzira yo hejuru izahindurwa hakurikijwe inyungu-nyayo, kandi ibyiciro nibisabwa bizahinduka muguhindura isoko.Mugihe kimwe, isesengura ryinyungu rigomba guhuzwa nibikorwa byinganda.Dufashe PVC nkurugero, igomba kwigabanyamo kwishyira hamwe no kudashyirwa hamwe.Mubyongeyeho, birakenewe guhuza inyungu yibuye na alkali.Byongeye kandi, uruganda rukusanya amashanyarazi rwabonye inyungu runaka nkurwego rwo hejuru rwinganda, kandi igihombo cyibigo byahujwe biri muruganda.Mugihe kimwe, bigomba no gusuzumwa hamwe nibindi bintu.
