Inzira ya PVC, Inzira ya Carbide PVC na Ethylene PVC

PVC ni ubwoko bwa plastiki bukoreshwa cyane mubikoresho byo kubaka. Kubwibyo, ntabwo izasimburwa igihe kirekire mugihe kizaza, kandi izaba ifite amahirwe menshi yo gukoreshwa mubice bitaratera imbere mugihe kizaza.

Nkuko twese tubizi, hari inzira ebyiri zo kubyara PVC, bumwe nuburyo mpuzamahanga busanzwe bwa Ethylene, ubundi nuburyo bwa calcium karbide idasanzwe mubushinwa. Inkomoko yuburyo bwa Ethylene ahanini ni peteroli, mugihe inkomoko yuburyo bwa calcium karbide ari amakara, hekeste nu munyu. Aya masoko yibanze cyane mubushinwa. Kuva kera, Ubushinwa PVC bwuburyo bwa calcium karbide bwabaye kumwanya wambere. By'umwihariko kuva mu 2008 kugeza 2014, Ubushinwa PVC itanga umusaruro wa calcium karbide uburyo bwiyongera, ariko kandi bwazanye ibibazo byinshi byo kurengera ibidukikije.

Gukoresha ingufu za calcium karbide ikora ni nini cyane, ibi rero bizatera imbogamizi kubitanga amashanyarazi mubushinwa. Kubera ko amashanyarazi atangwa no gutwika amakara, igomba gukoresha amakara menshi, bityo gutwika amakara byanze bikunze byanduza ikirere. Nyamara, Ubushinwa bwagize ibyo buhindura muri politiki mu myaka yashize. Ubushinwa burahora buzamura urwego rwinganda. Ubu turashobora kubona ko Ubushinwa bwatumije peteroli nyinshi, kandi ibigo byaho birashishikarizwa gutumiza peteroli kugirango itunganyirize ibicuruzwa biva hasi. Kubwibyo, mu myaka yashize, hiyongereyeho inganda nyinshi nshya zitunganya Ethylene mu Bushinwa, kandi ubushobozi bushya bwa PVC bwo gukora mu Bushinwa mu myaka yashize ni ubushobozi bwo gutanga umusaruro wa etilene. Ubushobozi bwo gukora uburyo bwa calcium karbide yubushinwa bwahagaritse kwemerwa gushya. Kubwibyo, mugihe cya vuba, umubare wibimera bya Ethylene mubushinwa bizakomeza kwiyongera kandi kariside ya calcium izakomeza kugabanuka. Mu bihe biri imbere, Ubushinwa bwohereza mu mahanga ibicuruzwa bya Ethylene bizakomeza kwiyongera, kandi buhoro buhoro biza ku isonga mu bihugu byohereza ibicuruzwa mu mahanga PVC.
