Izinto eziningi zokupakisha isiphuzo emakethe okwamanje kunzima ukuhlangabezana nezidingo zokuphepha kokudla kuzwelonke kanye nemvelo, inkinga enkulu ehlanganisa i-benzene idlula ibhidi, amagciwane, izinsalela zensimbi enzima, njll.
I-Benzene iwuhlobo lwento eqinile ye-carcinogenic, ngokwesibonelo, ikakhulukazi ezimbotsheni, ezinamathelayo, ezisetshenziswa kabanzi ekukhiqizeni ukupakishwa kokudla.
Ngenxa yokuthi amabhizinisi amaningi antula ukulawula kanye nezindlela zokubona, izinto zokupakisha ukudla ziyi-benzene edlula ibhidi.
Izinto zokupakisha ezingafanelekile zingenza ukungcoliswa kokudla, futhi zibeke engozini impilo yabathengi.
i-solvent residual residual composite packaging evame ukukhiqizwa kuyinki yokuphrinta, i-solvent kanye nenqubo yokukhiqiza, izincibilikisi ezivame ukusetshenziswa njenge-toluene ne-butanone, i-ethyl acetate.
Idatha ye-GB9683—
Izinhlanganisela eziyinkimbinkimbi zango-1988, ngokwazo azikona ukubola, ukugayeka kokudla kanye nokumuncwa emzimbeni nakho akunjalo, ngakho-ke kubhekwa njengento ephephile, engenabuthi.
kodwa ngenxa yesidingo sokucubungula, lapho kuvame ukujoyina izithasiselo ezihlukahlukene, njenge-ejenti yokukhuthaza, i-ejenti yokuzivikela, i-ejenti yokugcwalisa, ukuletha izinkinga zokuphepha kokudla.
Irabha yokwenziwa ngokuyinhloko itholakala kumafutha amakhemikhali izinto zokusetshenziswa, uhlobo luningi, lwakhiwa i-monomer ngezinqubo ezihlukahlukene zezinhlanganisela ze-polymer, ama-molecule amancane mahhala ayingozi emzimbeni womuntu.
