Isesengura ryerekana iterambere ry’inganda za PVC (polyvinyl chloride) mu 2021, ubushobozi bw’umusaruro buzahagarara

1. Incamake yiterambere ryinganda za PVC

Polyvinyl chloride (PVC) ni polymer yakozwe na polymerisation ya vinyl chloride monomer (VCM) mubitangiza nka peroxide hamwe na azo compound cyangwa munsi yumucyo nubushyuhe ukurikije uburyo bwa polymerisation yubusa.icyiciro cy'ingenzi.

Ibisigarira bya polyvinyl chloride bigabanyijemo ahanini ibisigisigi rusange hamwe na paste resin ukurikije imikoreshereze yabyo: ibisigarira rusange (G resin) ni ibisigara bivangwa nubunini busanzwe bwa plasitike cyangwa inyongeramusaruro kugirango bibe ifu yumye cyangwa itose kugirango itungwe;ibisigazwa bya paste (P Resin) mubisanzwe bikozwe hamwe na plastike kugirango bibe paste yo gukoresha;hari na PVC ivanga resin, ni resin ya PVC isimbuza igice cya resin resin muguhuza mugihe cyo gukora PVC plastisol.

Ibyiciro byingenzi bya PVC resin

Uburyo nyamukuru bwo kubyaza umusaruro PVC resin harimo uburyo bwo guhagarika, uburyo bwinshi, uburyo bwa emulsiyo, uburyo bwo gukemura nuburyo bwa micro-guhagarika polymerisation.Urebye ku isi hose, uburyo bwo guhagarika nuburyo bwibanze bwo gukora bwa PVC rusange-intego ya resin, mugihe uburyo bwo kubyaza umusaruro PVC paste resin nuburyo bwa emulsion nuburyo bwa micro-guhagarika polymerisation.Bitewe nuburyo butandukanye bwo gukora, ubushobozi bwumusaruro wibisigarira byombi ntibushobora guhinduka mubindi.

2. Urunigi rwinganda zinganda za PVC

Igikorwa cyo gukora PVC ahanini ni "calcium carbide method" na "Ethylene method", kandi ibikoresho byayo ni amakara na peteroli.Ibihugu byinshi kwisi bikoresha inzira ya peteroli na gaze.Kubera ko Ubushinwa bukennye muri peteroli kandi bukungahaye ku makara, igihugu cyanjye cya PVC cyo gukora ahanini gishingiye ku buryo bwa kariside ya calcium.

Uruganda rwa PVC

Ibikoresho fatizo byo kubyaza umusaruro PVC hakoreshejwe calcium karbide ni amakara.Kuva mu 2012, umusaruro w’amakara mbisi mu gihugu cyanjye wagaragaje ko ubanza kugabanuka hanyuma ukiyongera.Nk’uko Ikigo cy'igihugu gishinzwe ibarurishamibare kibitangaza, mu 2021 umusaruro w'amakara mbisi mu gihugu uzagera kuri toni miliyari 4.13 mu 2021, wiyongereyeho toni miliyoni 228 ugereranije na 2020.

Ibikoresho fatizo byo gukora PVC muburyo bwa Ethylene ni amavuta ya peteroli.Nk’uko Ikigo cy'igihugu gishinzwe ibarurishamibare kibitangaza, igihugu cyanjye kizatanga toni miliyoni 198.98 za peteroli ya peteroli mu 2021, kikaba cyiyongereyeho toni miliyoni 4.06 ugereranije na 2020. Muri byo, toni miliyoni 16.47 z'amavuta ya peteroli yakozwe mu Kuboza, umwaka-ku- kwiyongera umwaka 1.7%.
