Izinto ezininzi zokupakisha iziselo kwimarike okwangoku kunzima ukuhlangabezana nokhuseleko lokutya lwesizwe kunye neemfuno zokusingqongileyo, eyona ngxaki iphambili kubandakanya i-benzene idlula ibhidi, ibhaktheriya, iintsalela zentsimbi enzima, njl.
I-Benzene luhlobo lwento eyomeleleyo ye-carcinogenic, umzekelo, ngokuyininzi kwi-coatings, i-adhesives, esetyenziswa ngokubanzi kwimveliso yokupakisha ukutya.
Ngenxa yokuba amashishini amaninzi engakwazi ukulawula kunye nokufumanisa iindlela, izixhobo zokupakisha ukutya ziyingozi kakhulu ye-benzene ngaphezu kwe-bid.
Izinto zokupakisha ezingafanelekanga zinokwenza ukungcoliseka kokutya, kwaye zibeke engozini impilo yabathengi.
I-solvent residual residual composite packaging eveliswa ngokubanzi kwi-inki yokushicilela, isinyibilikisi kunye nenkqubo yokuvelisa, izinyibilikisi ezisetyenziswa ngokuqhelekileyo njengetoluene kunye nebutanone, i-ethyl acetate.
I-GB9683—
Iikhompawundi ezintsonkothileyo zika-1988, zona ngokwazo aziboli, ukugaywa kunye nokufunxa emzimbeni akukho nto, kwaye ke ngoko ithathwa njengento ekhuselekileyo, engeyotyhefu yokupakisha.
kodwa ngenxa yesidingo sokucutshungulwa, apho bahlala bejoyina iindidi zezongezo, ezifana ne-ejenti yokukhuthaza, i-arhente yokukhusela, i-ejenti yokuzalisa, ukuzisa iingxaki zokhuseleko lokutya.
Irabha yokwenziwa ikakhulu ithathwe kwioyile yeekhemikhali izinto ekrwada, uhlobo lungaphezulu, luqulunqwe yi-monomer ngokusebenzisa iinkqubo ezahlukeneyo zekhompawundi zepolymer, iimolekyuli ezincinci ezisimahla ziyingozi kumzimba womntu.
