Intangiriro kubyerekeranye n'ubushobozi bwa PVC mubushinwa no kwisi yose

Dukurikije imibare yo mu 2020, ubushobozi bwa PVC ku isi hose bwageze kuri toni miliyoni 62 naho umusaruro wose wageze kuri toni miliyoni 54. Kugabanuka kwumusaruro byose bivuze ko ubushobozi bwo gukora butigeze bukora 100%. Kubera ibiza, politiki zaho nibindi bintu, umusaruro ugomba kuba munsi yubushobozi bwumusaruro. Bitewe n’igiciro kinini cy’ibicuruzwa bya PVC mu Burayi no mu Buyapani, ubushobozi bwa PVC ku isi bwibanda cyane cyane muri Aziya y’Amajyaruguru y’Amajyaruguru, aho Ubushinwa bufite hafi kimwe cya kabiri cy’ubushobozi bwa PVC ku isi.

Nk’uko imibare y’umuyaga ibigaragaza, mu 2020, Ubushinwa, Amerika n’Ubuyapani n’ahantu h’ingenzi hakorerwa PVC ku isi, aho ubushobozi bw’umusaruro bugera kuri 42%, 12% na 4%. Muri 2020, ibigo bitatu bya mbere mubushobozi bwa PVC ku isi byongera umusaruro ni Westlake, shintech na FPC. Muri 2020, umusaruro wa PVC wumwaka wari toni miliyoni 3.44, toni miliyoni 3.24 na toni miliyoni 3.299. Icya kabiri, ibigo bifite ubushobozi bwo gutanga umusaruro urenga toni miliyoni 2 nabyo birimo inovyn. Ubushinwa butanga umusaruro wose ni toni miliyoni 25, umusaruro wa toni miliyoni 21 muri 2020. Mu Bushinwa hari inganda zirenga 70 za PVC, 80% muri zo ni uburyo bwa kariside ya calcium na 20% ni uburyo bwa Ethylene.

Benshi muburyo bwa calcium karbide yibanze ahantu hakungahaye ku mutungo wamakara nka Mongoliya Imbere na Sinayi. Ahantu hateganijwe gutunganyirizwa Ethylene iherereye mubice byinyanja kuko ibikoresho bibisi VCM cyangwa Ethylene bigomba gutumizwa hanze. Ubushinwa butanga umusaruro hafi kimwe cya kabiri cy’isi, kandi hamwe n’ukomeza kwaguka kw’inganda z’inganda zo mu Bushinwa, ubushobozi bwa PVC bw’uburyo bwa Ethylene buzakomeza kwiyongera, kandi Ubushinwa buzakomeza kwangiza umugabane mpuzamahanga wa PVC.
