Izizinzisi zolwelo zidlala indima ebalulekileyo ekwenzeni iithoyi zeplastiki. Ezi zinzisi zolwelo, njengezongezo zekhemikhali, zixutywa kwimathiriyeli yeplastiki ukomeleza ukusebenza kweethoyi, ukhuseleko, kunye nokuqina. Usetyenziso oluphambili lwezinzisi zolwelo kwiithoyi zeplastiki ziquka:
Ukhuseleko olomeleziweyo:Izinzisi zolwelo zinceda ekuqinisekiseni ukuba iithoyi zeplastiki ziyahlangabezana nemigangatho yokhuseleko ngexesha lokusetyenziswa. Bancedisa ekunciphiseni ukukhutshwa kwezinto eziyingozi, ukuqinisekisa ukuba izinto zokudlala zikhuselekile ukuba abantwana badlale ngazo.
Ukuphuculwa koKuhlala ixesha elide:Izinto zokudlala zeplastiki kufuneka zimelane nokudlala rhoqo kunye nokusetyenziswa ngabantwana. Izizinzi zolwelo zinokomeleza ukuxhathisa kweplastiki ukuqhotyoka kunye nokuchasana nempembelelo, zandisa ubomi bezinto zokudlala.
Ukuchasa amabala:I-stabilizers yolwelo inokubonelela ngamathoyizi eplastiki ngokuxhathisa amabala, okwenza kube lula ukucoca nokugcina kwimeko ecocekileyo necocekileyo.
Iimpawu zeAntioxidant:Izinto zokudlala zePlastiki zinokuvezwa emoyeni kwaye zichaphazeleke kwi-oxidation. I-stabilizers yolwelo inokubonelela ngokhuseleko lwe-antioxidant, ukunciphisa ukuguga kunye nokuwohloka kwezinto zeplastiki.
Uzinzo Lombala:Izinzisi zolwelo zinokuphucula uzinzo lombala wezinto zokudlala zeplastiki, zithintele ukufiphala kombala okanye utshintsho kunye nokugcina umtsalane wembonakalo yezinto zokudlala.
Isishwankathelo, izizinzisi zolwelo zidlala indima ebalulekileyo ekwenzeni iithoyi zeplastiki. Ngokubonelela ngezincedisi zokusebenza eziyimfuneko, baqinisekisa ukuba iithoyi zeplastiki zigqwesa kukhuseleko, ukuqina, ukucoceka, nokunye, kubenza bafanelekele ukudlala nokuzonwabisa kwabantwana.
