Nokuba siya kwindawo yokutyela isidlo sakusasa okanye siodole ukutya, sihlala sibona le nto: umphathi ngobuchule ukrazule ingxowa yeplastiki, ayibeke kwisitya, aze ekugqibeleni abeke ukutya kuyo ngokukhawuleza.Enyanisweni, kukho isizathu soku.: Ukutya kudla ngokudyojwa ngeoli.Ukuba ifuna ukucocwa, ithetha umsebenzi owongezelelweyo.Kwimodeli yeshishini "yevolumu ephezulu kunye nenzala ephantsi" efana nevenkile yesidlo sakusasa, ingxowa yeplastiki engabizi kakhulu inokubenza kube lula kakhulu.
Kodwa kukho abantu abaninzi abachasayo kakhulu kule nto, becinga ukuba iingxowa zeplastiki "ziikhemikhali".Xa kuthelekiswa nezitya ze-porcelain zemveli, zibonakala zisempilweni kumphezulu, kodwa eneneni, zibeka ingozi enkulu yokhuseleko kwimpilo.Ngokukodwa xa ubeka "ukutya okunobushushu obuphezulu" njengama-noodle kunye nesobho esanda kuphuma embizeni, unokuvumba ngokucacileyo iphunga leplastiki, elinokuthi livunywe ngokungathandekiyo ekukhanyeni, okanye libuyisele kwaye linzima ukuligwinya kakhulu, libangele. ezinye "iingxabano" ezingeyomfuneko.
Ke ngaba iiplastiki zinetyhefu ngokwenene emva kokuba zizaliswe kukutya okushushu?
Okokuqala, kuyimfuneko ukuqonda ukuba izikhwama zeplastiki zenziwe "i-polyethylene", "i-polypropylene", "i-polyvinyl chloride" njalo njalo.Ngokwembono yobuchwephesha, i-polyethylene inawo umngcipheko wemvula ye "toxic monomer ethylene", kodwa ukubakho kwemvula "ye-polyethylene yodidi lokutya" iphantsi kakhulu.Iingxowa zeplastiki ezasasazwa ngaphambili ngokuqhelekileyo zenziwe nge "polypropylene", kuba inamandla okumelana nobushushu obuphezulu (160 ° -170 °), kwaye nokuba ishushu nge-microwave, ayiyi kuvelisa iphunga elikhethekileyo.Ngokutsho kobushushu obuphezulu bemvula yokutya kwi-100 °, akukho phantse "ii-monomers ezinetyhefu" kwiingxowa zeplastiki ze-polypropylene, kodwa isiseko kukuba iingxowa zeplastiki ezisetyenzisiweyo kufuneka zibe "kwibakala lokutya".
Ukuthetha ngenjongo: into ebizwa ngokuba "into" kwi "polypropylene" ayithethi ukuba yikhemikhali eyityhefu.Kungcono ukuba ungayityi, kodwa akufanele ukhathazeke kakhulu xa uyityile.
