Iplastiki yinto yokwenziwa okanye ye-semi-synthetic eyomeleleyo, engasindi, kwaye eguqukayo.

Ezi ndawo zivumela ukuba yenziwe kwiimveliso ezahlukeneyo, kubandakanya izixhobo zonyango, izinto zeemoto, kunye nezinto zekhaya ezinje ngezitya zokugcina ukutya, izikhongozeli zesiselo, kunye nezinye izitya.

Nangona kunjalo, usenokuzibuza ukuba ingaba unokukhusela i-microwave ngokukhuselekileyo ukulungiselela ukutya, ukufudumeza isiselo sakho osithandayo, okanye ukuphinda uphinde uphinde uphinde ushiye okuseleyo.

Eli nqaku lichaza ukuba ungazenza ngokukhuselekileyo kwiiplowave zeplastiki.

Iindidi zeplastiki

Iplastiki yinto enamakhonkco amade ee polymers, aqulathe amawaka aliqela aphindaphindiweyo abizwa ngokuba yi-monomers ().

Ngelixa zihlala zenziwe nge-oyile kunye negesi yendalo, iiplastiki zinokwenziwa nakwizinto ezinokuphinda zenziwe ezinje ngomgubo wokhuni kunye neentsimbi zomqhaphu ().

Kwisiseko seemveliso ezininzi zeplastiki, uyakufumana unxantathu wokurisayikilisha ngenani - ikhowudi yokuchonga intlaka - ukusukela ku-1 ukuya ku-7. Inani likuxelela ukuba loluphi uhlobo lweplastiki elenziwe ngalo ().

Iindidi ezisixhenxe zeplastiki kunye neemveliso eziveliswe kuzo zibandakanya (, 3):

1. I-Polyethylene terephthalate (i-PET okanye i-PETE): iziselo zibhotile zesoda, ibhotolo yamandongomane kunye neejayi zemayonnaise, nezitya zeoyile yokupheka
2. Ukuxinana okuphezulu kwe-polyethylene (iHDPE): izitya zokucoca kunye nezesepha zesandla, iijagi zobisi, izitya zebhotolo, kunye neeprotein zepowder tubs
3. Polyvinyl chloride (PVC): imibhobho yemibhobho yamanzi, iintambo zombane, amakhethini eshawa, ityhubhu yezonyango, kunye neemveliso zesikhumba zokwenziwa
4. Ubuninzi be-polyethylene (LDPE): iiplastikhi, cudisa iibhotile, kunye nokupakisha ukutya
5. Polypropylene (PP): Iibhotile zebhotile, izikhongozeli zeyogathi, izikhongozeli zokugcina ukutya, iicapsule zekofu ezisebenza kunye, iibhotile zabantwana kunye neebhotile zokugungqa
6. IPolystyrene okanye iSyrofoam (PS): ukupakisha amandongomane nezitya zokugcina ukutya, iipleyiti kunye neekomityi ezilahlwayo
7. Okunye: ibandakanya i-polycarbonate, i-polylactide, i-acrylic, i-acrylonitrile butadiene, i-styrene, i-fiberglass kunye nenayiloni

Ezinye iiplastiki zinezongezelelo zokufezekisa iipropathi ezinqwenelekayo zemveliso egqityiweyo (3).

Ezi zongezelelo zibandakanya imibala, ukuqiniswa kunye nokuzinzisa.

Iplastiki yenziwa ikakhulu nge-oyile kunye negesi yendalo. Kukho iintlobo ezininzi zeplastiki ezinezicelo ezahlukeneyo.

Ngaba ikhuselekile kwimicrosoft microwave?

Eyona nkxalabo iphambili ngeplastikhi ye-microwaving kukuba inokubangela izongezo-ezinye zazo zinobungozi -ukungena kukutya nakwiziselo.

Iikhemikhali eziphambili zenkxalabo yi-bisphenol A (BPA) kunye nodidi lweekhemikhali ezibizwa ngokuba zii-phthalates, zombini zisetyenziselwa ukwandisa ubhetyebhetye kunye nokuqina kweplastiki.

Ezi khemikhali-ngakumbi i-BPA-ziphazamisa iihormoni zomzimba wakho kwaye zinxulunyaniswe nokutyeba, isifo seswekile, kunye nokwenzakala kokuzala (,,,).

I-BPA ifunyanwa ikakhulu kwiiplastikhi ze-polycarbonate (PC) (inombolo 7), ebisetyenziswa ngokubanzi ukusukela ngeminyaka yoo-1960 ukwenza izikhongozeli zokugcina ukutya, iiglasi zokusela kunye neebhotile zabantwana ().

I-BPA evela kwezi plastikhi inokungena kwizidlo nakwiziselo ekuhambeni kwexesha, kunye naxa iplastikhi ivezwe ubushushu, njengaxa i-microwaved (,,).

Nangona kunjalo, namhlanje, abanye abavelisi bokulungiswa kokutya, ukugcinwa kunye nokuhanjiswa kweemveliso batshintshe iplastiki yePC yeplastiki engenasimahla ye-BPA njenge-PP.

Ulawulo lokutya kunye neziyobisi (i-FDA) ikwalela ukusetyenziswa kwezixhobo ezisekwe kwi-BPA ekupakisheni ubisi olungumgubo lweentsana, iikomityi ze-sippy kunye neebhotile zabantwana ().

Okwangoku, uphononongo lubonakalisile ukuba neeplastiki ezingasasebenziyo ze-BPA zinokukhupha ezinye iikhemikhali eziphazamisa iihomoni ezinje ngee-phthalates, okanye ezinye iindlela ze-BPA ezinje nge-bisphenol S kunye ne-F (BPS kunye ne-BPF), ekutyeni xa kusenziwa i-microwaved (,,,).

Ke ngoko, kungumbono olungileyo ukunqanda iplastikhi ye-microwave, ngaphandle kokuba-ngokwe-FDA-isikhongozeli sibhalwe ngokukhuselekileyo ukusetyenziswa kwemicrowave ().

Iiplastikhi zeMicrowave zinokukhupha iikhemikhali eziyingozi njengeBPA kunye neephthalates kukutya nakwiziselo zakho. Ke ngoko, kuya kufuneka uyiphephe imicroave yeplastiki, ngaphandle kokuba inelebheli yokusetyenziselwa oku.

Ezinye iindlela zokunciphisa ukubonakaliswa kwakho kwi-BPA kunye ne-phthalates

Ngelixa i-microwaving plastiki ikhawulezisa ukukhutshwa kwe-BPA kunye nee-phthalates, ayisiyiyo kuphela indlela ezinokuphela ngayo ezi khemikhali kukutya okanye iziselo zakho.

Eminye imiba enokwandisa i-leaching yamachiza ibandakanya (,):

• ukubeka ukutya kwizikhongozeli zeplastiki ezishushu
• ukukhuhla izikhongozeli kusetyenziswa izinto ezirhabaxa, ezinje ngoboya bentsimbi, ezinokubangela ukukrwela
• usebenzisa izikhongozeli ixesha elide
• ukuveza izikhongozeli kwindawo yokuhlamba izitya kaninzi ekuhambeni kwexesha

Njengomgaqo oqhelekileyo, izikhongozeli zeplastikhi eziqhekekileyo, zokungqisha, okanye zokubonisa iimpawu zokunxiba, kufuneka zitshintshwe ngezikhongozeli ezitsha ezingenanto zeBPA okanye izikhongozeli ezenziwe ngeglasi.

Namhlanje, izikhongozeli ezininzi zokugcina ukutya zenziwe nge-BPA-free PP.

Ungachonga izikhongozeli ezenziwe kwi-PP ngokujonga ezantsi kwisitampu se-PP okanye uphawu lokurisayikilisha nenombolo yesi-5 embindini.

Ukupakishwa kokutya okwenziwe ngeplastikhi njengokugoqwa kweplastikhi okubambekayo nako kunokuqulatha i-BPA kunye neephthalates ().

Kananjalo, ukuba ufuna ukugubungela ukutya kwakho kwi-microwave, sebenzisa iphepha le-wax, iphepha lesikhumba, okanye itawuli yephepha.

Izikhongozeli zeplastiki ezikrwitshiweyo, ezonakeleyo, okanye ezinxitywe ngokugqithisileyo, zibeka umngcipheko omkhulu wokudibana kwemichiza.

Umgca wezantsi

Iiplastikhi zizinto ezenziwe ubukhulu becala ngeoyile okanye ipetroleum, kwaye zinokusetyenziswa okwahlukeneyo.

Ngelixa ukutya okuninzi kugcinwa, ukulungiswa, kunye nokuhanjiswa kweemveliso kwenziwa ngeplastiki, ukuzigcina kwimicro microwave kunokukhawulezisa ukukhutshwa kweekhemikhali eziyingozi njengeBPA kunye neephthalates.

Ke ngoko, ngaphandle kokuba imveliso yeplastiki ithathwa njengekhuselekileyo kwimicrowave, kuthintele ukuyifaka kwimicroowave, kwaye ubeke endaweni yazo izitya zeplastiki ezigugileyo.
