Kungakhathaliseki ukuthi siya endaweni yokudlela yasekuseni noma si-oda ukudla, sivame ukubona lesi simo: umphathi udabule isikhwama sepulasitiki ngobuchule, bese esibeka endishini, futhi ekugcineni afake ukudla kuso ngokushesha.Eqinisweni, kunesizathu salokhu.: Ukudla kuvame ukugcotshwa ngamafutha.Uma idinga ukuhlanzwa, kusho umsebenzi owengeziwe.Ngemodeli yebhizinisi "yevolumu ephezulu kanye nenzalo ephansi" njengezitolo zasekuseni, isikhwama sepulasitiki esishibhile singabalethela ukunethezeka okukhulu.
Kodwa futhi kukhona abantu abaningi abaphikisana kakhulu nalokhu, becabanga ukuthi izikhwama zepulasitiki "zingamakhemikhali".Uma kuqhathaniswa nezitsha ze-porcelain ezivamile, zibonakala ziphilile ebusweni, kodwa empeleni, zibeka ingozi enkulu yokuphepha empilweni.Ikakhulukazi lapho ubeka "ukudla okushisa kakhulu" njengama-noodle nesobho esisanda kuphuma ebhodweni, ungakwazi ukuhogela iphunga lepulasitiki, elingamukelwa ngokungafuni ekukhanyeni, noma ukuhlehlisa futhi kunzima ukugwinya okubi kakhulu, okubangela ezinye “izingxabano” ezingadingekile.
Ngakho ingabe izikhwama zepulasitiki zinobuthi ngempela ngemva kokuba zigcwaliswe ukudla okushisayo?
Okokuqala, kubalulekile ukuqonda ukuthi izikhwama zepulasitiki zenziwe "polyethylene", "polypropylene", "polyvinyl chloride" njalonjalo.Ngokombono wochwepheshe, i-polyethylene inayo ingcuphe yokuna kwe-“toxic monomer ethylene”, kodwa ithuba lokuna kwe- “polyethylene yebanga lokudla” liphansi kakhulu.Izikhwama zepulasitiki ezasakazwa ngaphambili ngokuvamile zenziwe "i-polypropylene", ngoba inokumelana okuqinile kokushisa okuphezulu (160 ° -170 °), futhi ngisho noma ishiswa nge-microwave, ngeke ikhiqize iphunga elingavamile.Ngokusho kokushisa okuphezulu kwezulu lokudla ku-100 °, cishe awekho "ama-monomers anobuthi" "ezikhwameni zepulasitiki ze-polypropylene", kodwa isisekelo siwukuthi izikhwama zepulasitiki ezisetshenziswayo kufanele zibe "ibanga lokudla".
Ukukhuluma ngezinhloso: lokho okubizwa ngokuthi "into" ku "polypropylene" akusho ukuthi ikhemikhali enobuthi.Kungcono ukungakudli, kodwa akudingekile ukuba ukhathazeke kakhulu uma ukudlile.
