Abakiriya benshi ntibasobanutse neza kubijyanye no kutagira uburozi no kurengera ibidukikije bya shitingi ya PVC, kandi batekereza ko uburozi butangiza ibidukikije.Mubyukuri, ntabwo aribyo.Kugira ngo twumve neza ibi bitekerezo byombi, tugomba kubanza gutandukanya ibikoresho fatizo nogukoresha imiyoboro.
Kwinjiza amashanyarazi ya PVC ni ugukorera rubanda no kuyakoresha mubuzima bwa buri munsi bwabantu, ariko igarukira gusa kumesa hasi, indabyo, ubusitani, ibikoresho byimashini, sheath, nibindi. Mu ntangiriro, abakozi kumyubakire ndetse Yarakoreshejwe amazi yo gutanga.Duhereye kuri izi ngingo, izishobora guhura nabantu igihe kirekire zigomba gufatwa nkuburozi cyangwa uburangare, ariko ibi bigarukira kubikoresho byumwimerere.
Igitekerezo cyo kurengera ibidukikije ni kigari cyane, kanda kuri Baidu, hano kugirango uvuge ku gitekerezo cyo kurengera ibidukikije bya shitingi ya PVC, bivuze ko ibintu byaguye nyuma yo kwangirika kwamazu ya PVC bitazangiza umubiri wumuntu.PVC ni polyethylene, ni ifu ya resin.Ibigize ibintu byangiza ibintu muri hose biva mubindi bikoresho bibisi bigize hose, butyl ester, paraffine ya chlorine, (cyangwa octyl ester, p-benzene, TOTM).Amabati asanzwe akozwe muri PVC, butyl ester, chlorine Igizwe nigishashara cya paraffin nibindi bisohora.Butyl ester na paraffine ntibishobora kugusha benzene mugihe ubushyuhe buri munsi ya dogere selisiyusi 45, bityo bikaba bifite umutekano kandi ntabwo ari uburozi.
Kurengera ibidukikije bivuze ko amabati ya PVC yatsinze igenzura ryinzego zemewe nta mvura ya phthalate ishobora gukoreshwa mu miyoboro y’amazi yo kunywa kandi bigasuzumwa ko bitangiza ibidukikije.Iki gisabwa kiragoye, kandi ibikoresho byangiza ibidukikije byonyine bikoreshwa.
Kubwibyo, mugihe uhisemo hose, gerageza gukoresha ibitari uburozi cyangwa ibidukikije byangiza ibidukikije kugirango ukoreshe urugo.Igiciro nticyoroshye gusa mugihe cyo kwishyura, kandi mugihe cyo gukoresha ibicuruzwa, hari umunezero uherekejwe, kandi gukoresha umuyoboro nta mpungenge.
