Zvipingamupinyi zvehunyanzvi uye kukwana kwazvino mukuvandudza kwemaindasitiri zvinowanzo kunetsa kupaza, uye zvakafanana nezvezvigadzirwa zvepurasitiki muChina.Mabatiro aungaite giridhi isiri chepfu, nzira yekukunda zvipingaidzo zvehunyanzvi zvekumadokero epurasitiki ndiyo yanga iri tarisiro yekutsvaga kwemaindasitiri. Munguva pfupi yapfuura, mashoko akanaka akauya kuti Zhengzhou University yakagadzira yakasvibirira isina chepfu plasticizer, iyo ichaunza mabhenefiti kune iko kurongedza kwekudya kwezvigadzirwa zvepurasitiki muChina.
Nyika yedu inokunda plasticizer tekinoroji chipingamupinyi girini isiri chepfu plasticizer kurongedza kuchauya
Yakatungamirwa naPurofesa Liu Zhongyi weChikoro Chemistry uye Molecular Injiniya yeZhengzhou University, timu yesainzi yekutsvagisa yeGreen Catalytic Maitiro eDhipatimendi redzidzo reHenan Province, mushure megore rinopfuura gore rekutsvagurudza, munguva pfupi yapfuura yakabudirira iyo isiri-chepfu ye phthalic plasticizer murabhoritari, uye iko kuita kukuru kwechigadzirwa kwasvika kuEuropean Standard kune mamwe epurasitiki, uye yave kuda kupinda muyedzo yekuyedza. Mushure mekugadzirwa kwakawanda, zvinotarisirwa kuti zvione kusakwana-kutyisa kwezvigadzirwa zvepurasitiki mune zvakawanda. minda muChina.
Zvinoenderana nekuunza, o-benzene kirasi plasticizer ndiyo inonyanya kushandiswa pasi rese, huwandu hukuru hwepurasitiki yekugadzirisa, kugadzirwa kwemakemikari evaxilaries, anoshandiswa zvakanyanya mupurasitiki, rabha, adhesives, cellulose, resin, zvekurapa michina, tambo nezvimwe zvigadzirwa. Nekudaro, iyo benzene mhete chimiro mune phthalic plasticizer inokuvadza kuvanhu, mhuka, chirimwa uye nharaunda, kunyanya kuhurongwa hwekubereka kwevanhu. Nekuda kweizvozvo, iyo Eu yakagamuchira rairo pakupera kwa2005 inorambidza kushandiswa kwemaphthalates mune zvigadzirwa zvinouya. kusangana nepedyo nemuviri wemunhu, senge chikafu, kurapa kurapa uye matoyi evana. Kubva 2011, nyika zhinji, kusanganisira China, dzakaisa zviyero zvakafanana neEU. Zvigadzirwa zvisina chepfu zvepurasitiki munyika medu zvinokurumidza zvakanyanya.
Nekuda kweiyi tsvagiridzo, kusimudzira kwemaindasitiri kuri kuzadzikiswa, uye zvipingaidzo zvehunyanzvi uye zvakaomarara zviyero zveEU zvichaputswa.Panguva imwecheteyo, nekugadzirwa kwevagadziri vemumba, mutengo we green green isiri chepfu plasticizer inotarisirwa kudonha zvakanyanya, maindasitiri ese ezasi, kusanganisira vatengiwo zvavo vanozobatsirwa nazvo.
