Imiterere y'imbere mu gihugu n'iterambere ry'inganda za PVC mu Bushinwa

PVC ni kimwe mu bikoresho bitanu bya resin bikoreshwa mu buryo bwose, gifite imiterere myiza nko kurwanya aside na alkali, kurwanya kwangirika, kudashira kw'inkongi y'umuriro, no gukingira. Kuri ubu, yabaye iya kabiri mu bicuruzwa bya pulasitiki binini ku isi nyuma ya polyethylene.
1. Ubushobozi bwo gukora PVC mu gihugu n'umusaruro wayo
Uburyo bwo gukora PVC bugizwe ahanini n'inzira ebyiri: uburyo bwa karubone ya kalisiyumu n'uburyo bwa ethylene, itandukaniro rikomeye rikaba uburyo bwo gutegura monomer ya vinyl chloride.
Mu myaka ya vuba aha, umusaruro wa PVC wagiye uzamuka uko umwaka utashye, kandi ubushobozi bw'inganda zose bwo gukora bwageze ku rwego rwo hejuru. Ubukene bw'isoko bwagiye buzamuka buhoro buhoro, kandi umusaruro wakomeje kwiyongera. Dukurikije amakuru aturuka muri China Chloroalkali Network, igipimo rusange cy'imikorere y'inganda za PVC zo mu Bushinwa cyagumye hejuru ya 50% mu myaka yashize.
2. Iterambere ry'Inganda za PVC
(1) Gushimangira iyubakwa ry'ibikoresho byo guhuza inganda
Kuva mu 2007, igihugu cyashyizeho amabwiriza arambuye atanga amabwiriza arambuye yo guteza imbere inganda za PVC. Muri icyo gihe, gishishikariza kubaka ibikoresho bishyigikira ibigo bitunganya karubone na chlor alkali, kandi gishimangira iyubakwa ry'ibikoresho bihuza inganda. Biyobowe na politiki y'igihugu iriho ubu, ishyirwaho ry'ibikoresho bihuza inganda ryabaye ikintu kidasubirwaho mu turere two hagati n'utw'iburengerazuba bw'Ubushinwa, dukungahaye ku mabuye y'agaciro, ibicukurwa by'umunyu, n'umutungo wa limestone. Bitewe n'inshingano z'ibikoresho bihuza, hishingikirijwe ku byiza by'umutungo n'inyungu zihuye, ikiguzi cy'umusaruro gishobora kugenzurwa neza kandi ibicuruzwa bitandukanye bishobora kongera gukoreshwa, byongere ubushobozi bwo guhangana ku isoko n'ubushobozi bwo kubaho bw'ikigo.
(2) Uburyo butandukanye bwo gukora
Mu iterambere ririho ry’ibigo bya PVC byo mu gihugu, kwibanda ku gukwirakwiza ibikoresho mu buryo butandukanye buri kwiyongera, bigatuma ibyo bakeneye ku rwego rw’ikoranabuhanga birushaho kuba hejuru. Icyerekezo cyo gukwirakwiza ibikoresho mu buryo butandukanye kidahagarara. Hamwe n’iterambere ry’ibikorwa byo gukora PVC mu gihugu, ibigo bigomba gushyira mu bikorwa buhoro buhoro uburyo bushya bwo gukora ariko bigakomeza uburyo bwa karubone ya karubone. Muri icyo gihe, ikoranabuhanga rya polymerization rya PVC naryo rizarushaho kunozwa cyane, cyane cyane mu bijyanye n’ubushobozi bwo gukora polymerization reactors. Byongeye kandi, ni ngombwa gushyiraho ikoranabuhanga rigezweho mu gukora ibikoresho byo mu mahanga no kubiteza imbere buhoro buhoro kugira ngo kunoze ubukungu bw’inganda.
