Ipulasitiki yinto yokwenziwa noma yokwenziwa okuqinile okuhlala isikhathi eside, engasindi, futhi eguquguqukayo.

Lezi zakhiwo zikuvumela ukuthi kwenziwe imikhiqizo enhlobonhlobo, kufaka phakathi amadivayisi wezokwelapha, izingxenye zezimoto, nempahla yasendlini njengeziqukathi zokugcina ukudla, iziqukathi zesiphuzo, nezinye izitsha.

Kodwa-ke, ungahle uzibuze ukuthi ungakwazi yini ukuphepha ama-microwave plastic ukulungiselela ukudla, ukufudumeza isiphuzo sakho osithandayo, noma ukuvuselela okusalile.

Lo mbhalo uchaza ukuthi ungakwazi yini ukuphepha ngemicrowave plastic.

Izinhlobo zepulasitiki

IPlastiki yinto enamaketanga amade ama-polymers, aqukethe amayunithi ayizinkulungwane eziningana eziphindayo abizwa ngama-monomers ().

Ngenkathi zivamise ukwenziwa ngoyili negesi yemvelo, amapulasitiki angenziwa futhi ngezinto ezivuselelekayo ezifana nokhuni lomuthi kanye nama-linters okotini ().

Emazingeni emikhiqizo eminingi epulasitiki, uzothola unxantathu osebenza kabusha onenombolo - ikhodi yokukhomba yenhlaka - esukela ku-1 kuye ku-7. Inombolo ikutshela ukuthi yenziwe ngohlobo luni lwepulasitiki ().

Izinhlobo eziyisikhombisa zepulasitiki nemikhiqizo ekhiqizwe kuzo kufaka phakathi (, 3):

1. I-Polyethylene terephthalate (i-PET noma i-PETE): iziphuzo eziphuza isoda, ibhotela lamantongomane nezimbiza zemayonnaise, neziqukathi zikawoyela wokupheka
2. High ukuminyana polyethylene (HDPE): iziqukathi zensipho nezitsha zensipho, amajeke obisi, iziqukathi zebhotela, namabhabha e-protein powder
3. Polyvinyl chloride (PVC): amapayipi amapayipi, izintambo zikagesi, amakhethini eshawa, ithabhu lezokwelapha, nemikhiqizo yesikhumba yokwenziwa
4. Okuphansi ukuminyana polyethylene (LDPE): izikhwama zepulasitiki, khama amabhodlela, nokupakisha kokudla
5. I-Polypropylene (PP): izigqoko zamabhodlela, iziqukathi zeyogathi, iziqukathi zokugcina ukudla, amaphilisi ekhofi asebenzela umuntu oyedwa, amabhodlela ezingane namabhodlela e-shaker
6. I-Polystyrene noma i-Styrofoam (PS): ukupakisha amakinati nezitsha zokudla ezilahlwayo, amapuleti, nezinkomishi ezilahlwayo
7. Okunye: kufaka phakathi i-polycarbonate, i-polylactide, i-acrylic, i-acrylonitrile butadiene, i-styrene, i-fiberglass, nenayiloni

Amanye amapulasitiki aqukethe izithasiselo ukufeza izakhiwo ezifunwayo zomkhiqizo ophelile (3).

Lezi zithasiselo zifaka imibala, ama-reinforcements nama-stabilizers.

Ipulasitiki yenziwa ikakhulukazi ngoyili negesi yemvelo. Kunezinhlobo eziningana zepulasitiki ezinezinhlobonhlobo zezicelo.

Ingabe kuphephile ukwenza uplastiki wemicrowave?

Okukhathazeka kakhulu ngepulasitiki ye-microwaving ukuthi kungadala izithasiselo - ezinye zazo eziyingozi - ukungena ekudleni naseziphuzweni zakho.

Amakhemikhali ayinhloko okukhathazeka yi-bisphenol A (BPA) kanye nesigaba samakhemikhali abizwa ngokuthi ama-phthalates, womabili asetshenziselwa ukukhulisa ukuguquguquka nokuqina kwepulasitiki.

Lawa makhemikhali - ikakhulukazi i-BPA - aphazamisa amahomoni omzimba wakho futhi axhumene nokukhuluphala, isifo sikashukela, nokulimala kokuzala (,,,).

I-BPA itholakala kakhulu kuplastiki be-polycarbonate (PC) (inombolo 7), ebisetshenziswa kakhulu kusukela ngawo-1960 ukwenza iziqukathi zokugcina ukudla, izingilazi zokuphuza, namabhodlela ezingane ().

I-BPA evela kulama-plastiki ingangena ekudleni naseziphuzweni ngokuhamba kwesikhathi, kanye nalapho ipulasitiki ivezwa ekushiseni, njengalapho i-microwaved (,,).

Kodwa-ke, namuhla, abanye abakhiqizi bokulungiswa kokudla, ukugcinwa, kanye nemikhiqizo enikezwayo sebeshintshe ipulasitiki lePC ngeplastiki engenalo i-BPA efana ne-PP.

Ukuphathwa Kwezokudla Nezidakamizwa (i-FDA) nakho kuyakwenqabela ukusetshenziswa kwezinto ezisuselwa ku-BPA ekupakisheni ubisi lwefomula, izinkomishi ezi-sippy, namabhodlela ezingane ().

Noma kunjalo, ucwaningo luye lwabonisa ukuthi ngisho nama-plastiki angenayo i-BPA angakhipha amanye amakhemikhali aphazamisa ama-hormone njengama-phthalates, noma ezinye izindlela ze-BPA njenge-bisphenol S ne-F (BPS ne-BPF), ekudleni lapho i-microwaved (,,,).

Ngakho-ke, ngokuvamile kuwumqondo omuhle ukugwema ipulasitiki ye-microwaving, ngaphandle kwalapho - ngokusho kwe-FDA - isitsha sibhalwe ngokukhethekile ukuthi siphephile ukusetshenziswa kwama-microwave ().

I-Microwaving plastic ingakhipha amakhemikhali ayingozi njenge-BPA kanye nama-phthalates ekudleni naseziphuzweni zakho. Ngakho-ke, kufanele ugweme i-microwaving plastic, ngaphandle kokuthi ifakwe ilebula yalokhu kusetshenziswa okuthile.

Ezinye izindlela zokunciphisa ukuvezwa kwakho ku-BPA kanye nama-phthalates

Ngenkathi i-microwaving plastic isheshisa ukukhishwa kwe-BPA kanye ne-phthalates, akuyona ukuphela kwendlela lawa makhemikhali angagcina ngayo ekudleni noma eziphuzweni zakho.

Ezinye izinto ezingakhuphula ukuvuza kwamakhemikhali zifaka phakathi (,):

• ukubeka ukudla ezitsheni zepulasitiki ezisashisayo namanje
• ukukhuhla iziqukathi usebenzisa izinto ezihuqayo, njengoboya bensimbi, okungadala ukunwaya
• kusetshenziswa iziqukathi isikhathi eside
• ukuveza iziqukathi kumshini wokuwasha izitsha kaninginingi ngokuhamba kwesikhathi

Njengomthetho ojwayelekile, iziqukathi zepulasitiki eziqhephukile, ezigadlayo, noma ezibonisa izimpawu zokugqoka, kufanele zishintshwe ngeziqukathi zepulasitiki ezintsha noma iziqukathi ezintsha ezenziwe ngengilazi.

Namuhla, iziqukathi eziningi zokugcina ukudla zenziwe nge-PP engenayo i-BPA.

Ungabona iziqukathi ezenziwe nge-PP ngokubheka phansi isitembu se-PP noma uphawu lokuphinda lusetshenziswe nenombolo 5 phakathi.

Ukupakisha kokudla kwepulasitiki njengokugoqwa kwepulasitiki okunamathelayo nakho kungaqukatha i-BPA kanye ne-phthalates ().

Kanjalo, uma udinga ukumboza ukudla kwakho kwi-microwave, sebenzisa iphepha le-wax, iphepha lesikhumba, noma ithawula lephepha.

Iziqukathi zepulasitiki eziklwebhiwe, ezilimele, noma ezigqokwe ngokweqile, zibeka engcupheni enkulu yokuvuza kwamakhemikhali.

Okubalulekile

Amapulasitiki yizinto ezenziwe ngokuyinhloko ngoyili noma uphethiloli, futhi zinezinhlobonhlobo zezicelo.

Ngenkathi imikhiqizo eminingi yokugcina ukudla, ukulungiselela, nokuphaka yenziwa ngepulasitiki, ukuyigcina ngama-microwave kungasheshisa ukukhishwa kwamakhemikhali ayingozi njenge-BPA nama-phthalates.

Ngakho-ke, ngaphandle kokuthi umkhiqizo wepulasitiki uthathwe njenge-microwave ephephile, gwema ukuwugcina ngama-microwave, bese ushintsha iziqukathi zepulasitiki ezigugile ufake ezintsha.
