Kugeza ubu, byombi PVC ubwayo hamwe na kariside yo hejuru ya calcium iri murwego rwo hejuru.Dutegereje 2022 na 2023, kubera inganda za PVC zifite ingufu nyinshi zikoresha ingufu hamwe n’ibibazo byo kuvura chlorine, biteganijwe ko ibikoresho byinshi bitazashyirwa mu bikorwa.Inganda za PVC zishobora kwinjira mukizingo gikomeye mugihe cyimyaka 3-4.
Isoko rya calcium karbide ikomeje gutera imbere
Kalisiyumu karbide ninganda zitwara ingufu nyinshi, kandi ibisobanuro byitanura rya calcium karbide muri rusange ni 12500KVA, 27500KVA, 30000KVA, na 40000KVA.Amatanura ya karisiyumu munsi ya 30000KVA ni imishinga ibujijwe na leta.Politiki iheruka gutangwa na Mongoliya Imbere ni: itanura rya arc ryarohamye munsi ya 30000KVA, mubisanzwe, byose bisohoka mbere yimpera za 2022;abujuje ibisabwa barashobora gushyira mubikorwa gusimbuza ubushobozi kuri 1.25: 1.Nk’uko imibare y’umwanditsi ibigaragaza, inganda za calcium karbide mu gihugu zifite ubushobozi bwa toni miliyoni 2.985 ziri munsi ya 30.000 KVA, zingana na 8.64%.Amatanura ari munsi ya 30.000KVA muri Mongoliya Imbere arimo umusaruro wa toni 800.000, bingana na 6.75% yubushobozi bwose bwo gukora muri Mongoliya Imbere.
Kugeza ubu, inyungu ya karisiyumu ya calcium yazamutse igera ku rwego rwo hejuru mu mateka, kandi itangwa rya kariside ya calcium irabura.Igipimo cyimikorere ya feri ya calcium karbide yagombye kuba yagumye hejuru, ariko kubera ingaruka za politiki, igipimo cyibikorwa nticyigeze cyiyongera ahubwo cyaragabanutse.Inganda zo hasi za PVC nazo zifite igipimo kinini cyo gukora kubera inyungu zinjiza, kandi harakenewe cyane kariside ya calcium.Urebye imbere, gahunda yo gutangiza umusaruro wa calcium karbide irashobora gusubikwa kubera "kutabogama kwa karubone".Biragaragara ko biteganijwe ko uruganda rwa Shuangxin rufite toni 525.000 ruzashyirwa mu bikorwa mu gice cya kabiri cy’uyu mwaka.Umwanditsi yizera ko hazabaho byinshi byo gusimbuza ubushobozi bwa PVC mu gihe kiri imbere kandi bitazazana ibicuruzwa bishya byiyongera.Biteganijwe ko inganda za calcium karbide zizaba mu bucuruzi mu myaka mike iri imbere, kandi ibiciro bya PVC bizakomeza kuba hejuru.
Isoko rishya rya PVC riri hasi
PVC ninganda zitwara ingufu nyinshi, kandi igabanijwemo ibikoresho byo gutunganya etilene yinyanja hamwe nibikoresho bya calcium karbide yo mu gihugu imbere mubushinwa.Umubare w’umusaruro wa PVC wari mu 2013-2014, kandi umuvuduko w’ubwiyongere bw’ubushobozi bw’umusaruro wari hejuru cyane, bituma habaho ubushobozi bukabije mu 2014-2015, igihombo cy’inganda, kandi muri rusange ibikorwa byaragabanutse kugera kuri 60%.Kugeza ubu, ubushobozi bwa PVC bwavuye mu cyiciro gisagutse kijya mu bucuruzi, kandi igipimo cyo hejuru kiri hafi 90% y’amateka maremare.
Biteganijwe ko umusaruro muke wa PVC mu gihugu uzashyirwa mu musaruro mu 2021, kandi umuvuduko w’ubwiyongere bw’umwaka uzaba hafi 5% gusa, kandi biragoye kugabanya ibicuruzwa bitangwa.Bitewe nibisabwa bidahagaze mugihe cyibiruhuko, PVC kuri ubu irundanya ibihe, kandi urwego rwibarura ruri murwego rutabogamye umwaka-ku-mwaka.Biteganijwe ko nyuma yo gusabwa gusubukurwa mugice cya mbere cyumwaka, ibarura rya PVC rizakomeza kuba rito mugihe kirekire mugice cya kabiri cyumwaka.
Kuva mu 2021, Mongoliya y'imbere ntizongera kwemeza imishinga mishya yubushobozi nka kokiya (amakara yubururu), kariside ya calcium, na chloride polyvinyl (PVC).Niba ubwubatsi ari nkenerwa rwose, ubushobozi bwo kubyaza umusaruro no kugabanya ingufu zikoreshwa bigomba gushyirwa mubikorwa mukarere.Biteganijwe ko nta buryo bushya bwa calcium karbide uburyo bwa PVC bwo kubyaza umusaruro buzashyirwa mubikorwa usibye ubushobozi buteganijwe bwo gukora.
Ku rundi ruhande, umuvuduko w’ubwiyongere bw’ubushobozi bwa PVC mu mahanga wagabanutse kuva mu 2015, aho ikigereranyo cyo kwiyongera kiri munsi ya 2%.Muri 2020, disiki yo hanze izinjira mugihe cyo kugereranya ibintu.Kurenga ku ngaruka z’umuyaga w’Amerika mu gihembwe cya kane cya 2020 n’umuyaga ukonje muri Mutarama 2021, ibiciro bya PVC mu mahanga byazamutse bigera ku rwego rwo hejuru.Ugereranije n’ibiciro bya PVC mu mahanga, PVC yo mu gihugu ntabwo isuzugurwa, hamwe n’inyungu zoherezwa mu mahanga zingana na 1.500 / toni.Amasosiyete yo mu gihugu yatangiye kwakira ibicuruzwa byinshi byoherezwa mu mahanga guhera mu Gushyingo 2020, kandi PVC yahindutse ivuye mu bintu bitandukanye bigomba gutumizwa mu mahanga biva mu mahanga.Biteganijwe ko hazabaho ibicuruzwa byoherezwa mu mahanga mu gihembwe cya mbere cya 2021, bikaba byakajije umurego mu itangwa rya PVC mu gihugu.
Muri iki kibazo, igiciro cya PVC kiroroshye kuzamuka ariko biragoye kugabanuka.Kwivuguruza nyamukuru muri iki gihe ni ukuvuguruzanya hagati ya PVC ihenze cyane ninyungu zo hasi.Ibicuruzwa byo hasi muri rusange bifite izamuka ryibiciro bitinze.Niba PVC ihenze cyane idashobora koherezwa neza kumanuka, byanze bikunze bizagira ingaruka kumitangire yo gutangira no gutumiza.Niba ibicuruzwa byo hasi bishobora kuzamura ibiciro mubisanzwe, ibiciro bya PVC birashobora gukomeza kuzamuka.
