Izithiyo zobuchwepheshe kanye nemikhawulo yamanje ekuthuthukisweni kwezimboni kaningi kunzima ukuyiphula, futhi kunjalo nangemikhiqizo yeplasticizer eChina.Ukufeza kanjani okuluhlaza okungeyona enobuthi ngempela, ukuthi ungazinqoba kanjani izithiyo zobuchwepheshe ze-plasticizer yasentshonalanga kube ngukugxila ocwaningweni lomkhakha Muva nje, izindaba ezimnandi zeza ukuthi iZhengzhou University isungule i-plasticizer eluhlaza eluhlaza engeyona enobuthi, ezoletha izinzuzo ekupakisheni kokudla kwemikhiqizo yeplasticizer eChina.
Izwe lethu linqoba i-plasticizer technical barrier green plastic non-toxic plasticging packaging izofika
Iholwa nguSolwazi Liu Zhongyi weThe School of Chemistry and Molecular Engineering of Zhengzhou University, ithimba locwaningo lwesayensi leThe Green Catalytic Process of The Education Department of Henan Province, ngemuva konyaka ongaphezu kocwaningo, lisanda kuzuza ngempumelelo ukungabi nobuthi I-phthalic plasticizer elabhorethri, futhi ukusebenza okuyinhloko komkhiqizo kufinyelele kwi-European Standard yama-plasticizers afanayo, futhi sekuzongena esivivinyweni sokushayela.Ngemuva kokukhiqizwa ngobuningi, kulindeleke ukuthi kutholakale ukungabi yingozi ngokuphelele kwemikhiqizo yepulasitiki emikhakheni eminingi izinkambu eChina.
Ngokwethula, i-o-benzene class plasticizer iyona esetshenziswa kakhulu emhlabeni, inani elikhulu lokucutshungulwa kwepulasitiki, ukukhiqizwa kwamakhemikhali ama-auxilaries, okusetshenziswa kakhulu kupulasitiki, iraba, izinto zokunamathisela, iselulosi, i-resin, imishini yezokwelapha, ikhebula neminye imikhiqizo Kodwa-ke, ukwakheka kwendandatho ye-benzene ku-phthalic plasticizer kuyingozi kubantu, ezilwaneni, ezitshalweni nasemvelweni, ikakhulukazi ohlelweni lokuzala kwabantu.Ngenxa yalokho, u-Eu wamukela umyalelo ekupheleni konyaka ka-2005 ovimbela ukusetshenziswa kwama-phthalates emikhiqizweni ezayo ukuxhumana eduze nomzimba womuntu, njengokudla, ukupakishwa kwezokwelapha namathoyizi ezingane. Kusukela ngo-2011, amazwe amaningi, kufaka phakathi iChina, abeke amazinga afanayo ne-EU. Imikhiqizo ye-plasticizer engenabuthi ezweni lethu iphuthuma kakhulu.
Ngenxa yalolu cwaningo, ukuthuthuka kwezimboni kuyagcwaliseka kancane kancane, futhi kuzodilizwa izithiyo zobuchwepheshe namazinga aqinile e-EU.Ngasikhathi sinye, ngokukhiqizwa kwabakhiqizi basekhaya, intengo yeplastizerizer eluhlaza engenabuthi kulindeleke ukwehla kakhulu, zonke izimboni ezisezansi, kufaka phakathi abathengi abajwayelekile bazozuza kukho.
