Ni ibihe bibazo biri ku isoko ry'imfashanyo yo gutunganya PVC?

1. Haracyari icyuho runaka hagati yimfashanyigisho za PVC zo mu gihugu n’ibicuruzwa byo hanze, kandi ibiciro biri hasi ntabwo bifite inyungu nini mumarushanwa yisoko.
Nubwo ibicuruzwa byimbere mu gihugu bifite ibyiza bimwe na bimwe by’imiterere n’ibiciro mu guhatanira isoko, dufite icyuho runaka mu mikorere y’ibicuruzwa, bitandukanye, ituze, n’ibindi bintu ugereranije n’ibicuruzwa byo hanze. Ibi bifitanye isano no gusubira inyuma kwibicuruzwa byacu, tekinoroji yo gutunganya, gutunganya, hamwe nubuhanga bwa nyuma yubuvuzi. Ibigo bimwe byo mu gihugu birazi neza ibyo bibazo kandi byashyizeho umubano w’ubufatanye n’ibigo by’ubushakashatsi, ibigo by’ubushakashatsi n’iterambere, kandi bakora ubushakashatsi ku nyongeramusaruro.
2. Inganda nto ziratandukanye kandi ntamushinga uyobora ufite umwanya wuzuye, biganisha kumarushanwa adahwitse kumasoko.
Kugeza ubu, hari abakora uruganda rwa ACR bagera kuri 30, ariko 4 gusa muri bo bafite umusaruro munini (ufite ubushobozi bwo kwishyiriraho buri mwaka toni zirenga 5000). Ibicuruzwa byibi bigo binini byashizeho isura nziza haba mumasoko yimbere mugihugu ndetse no mumahanga, hatitawe kubintu bitandukanye nubwiza. Ariko mu myaka ibiri ishize, hamwe n’iterambere ry’inganda zitunganya PVC, inganda zimwe na zimwe za ACR zifite ubushobozi bwo gutanga umusaruro utarenze toni 1000 zihutiye ku isoko. Bitewe nibikoresho byoroheje byumusaruro hamwe nibidahungabana byibicuruzwa, ibyo bigo birashobora kubaho gusa hakoreshejwe guta ibiciro bidahenze, bikaviramo guhatanira ibiciro bikabije kumasoko yimbere mu gihugu. Ibicuruzwa bimwe na bimwe bidafite ubuziranenge kandi buke byahise byuzuza isoko, bizana ingaruka mbi ku nganda zitunganya ibicuruzwa kandi bikanazana ingaruka mbi ku iterambere ry’inganda. Birasabwa ko ishyirahamwe ritunganya plastike rifata iyambere mugushinga ishyirahamwe ryongera inganda za ACR, guhuza amahame yinganda, kugenzura iterambere ryinganda, gukuraho ibicuruzwa byiganano nibidakwiye, no kugabanya irushanwa ridahwitse. Muri icyo gihe, ibigo binini bigomba kongera imbaraga mu iterambere ry’ibicuruzwa, guhindura imiterere y’ibicuruzwa, no gukomeza iterambere rihuriweho n’ibicuruzwa by’amahanga bisa.
3. Kuzamuka kw'ibiciro bya peteroli byatumye izamuka ry’ibiciro fatizo ndetse n’inyungu z’amasosiyete zigabanuka.
Kubera izamuka ry’ibiciro bya peteroli mpuzamahanga bikomeje, ibikoresho byose by’ibanze bikomoka ku musaruro wa ACR, methyl methacrylate na estry acrylic ester, byazamutse cyane. Nyamara, abakiriya bo hasi basigaye inyuma mukuzamuka kwibiciro byibicuruzwa, bigatuma igabanuka rusange ryinyungu kubigo bitunganya ACR. Ibi byatumye habaho igihombo ku nganda zose mu 2003 na 2004. Kugeza ubu, kubera ihungabana ry’ibiciro fatizo, inganda zerekanye inzira nziza y’inyungu.
4. Kubura impano zumwuga, ubushakashatsi bwinganda ntabwo bwashoboye gutera imbere mubwimbitse
Bitewe nuko inyongeramusaruro ya ACR ninyongera ya polymer yibikoresho byateye imbere mubushinwa gusa mumpera za 90, ishami ryayo ryubushakashatsi niterambere hamwe nabashakashatsi ni mbarwa ugereranije nibindi byongeweho nka plasitike na retardants mu Bushinwa. Nubwo haba hari ibigo byubushakashatsi byabitezimbere, kutagira ubumwe bwiza hagati yabashakashatsi ninganda zitunganya plastike byatumye badashobora kongera ubushakashatsi bwibicuruzwa. Kugeza ubu, iterambere rya ACR mu Bushinwa rishingiye gusa ku bigo by’ubushakashatsi bifitwe n’ibigo bike kugirango bitunganyirize kandi biteze imbere. Nubwo hari ibyagezweho, hari itandukaniro rinini hagati ya bagenzi babo bo mu gihugu ndetse n’amahanga mu bijyanye n’inkunga y’ubushakashatsi, ibikoresho by’ubushakashatsi n’iterambere, hamwe n’ubushakashatsi n’iterambere ry’iterambere. Niba iki kibazo kidahinduwe neza, ntibizwi niba imfashanyo zitunganya zishobora guhagarara neza kumasoko yimbere mugihe kiri imbere.
