Indebe Yepulasitiki Yebanga Lokudla

Ipulasitiki yezinga lokudla ichazwa kangcono njengepulasitiki ephephile ekudleni. Leli gama libhekisela kunoma iyiphi ipulasitiki efanelekile ukuthintana nokudla noma imikhiqizo yeziphuzo engasetshenziswa.Indebe yepulasitiki yezinga lokudlakungavikela ukudla ekulimaleni, kuhlinzeke ngokuphepha kokudla futhi kwandise ubusha bokudla. Njengoba okunye ukudla okune-asidi noma uketshezi kungakhipha amakhemikhali ezitsheni zawo, kubalulekile ukuthi kugcinwe ezitsheni ezifanele.

Ku-COPAK, bonkeizinkomishi zepulasitiki zezinga lokudlaZenziwe nge-PET ne-PLA. Ensimini yepulasitiki, i-PET imakwe ngekhodi yiKhodi 1. Akudingeki ube uchwepheshe wepulasitiki ukuze unqume ukuthi into ethile iyizinga lokudla yini. Ikhodi iqukethe unxantathu wemicibisholo ezungeze inombolo ephakathi kuka-1 no-7. Ngokuvamile, izinombolo kusukela ku-1 kuya ku-7 zibonisa ipulasitiki yezinga lokudla.

I-PET ikhombisa ukumelana okuhle kakhulu nokuguguleka, amandla aphezulu kanye ne-flexural modulus, kanye nokuzinza okuphezulu kobukhulu (okungukuthi, ukumelana nokushayisana). I-Polyethylene terephthalate,izinkomishi zepulasitiki zezinga lokudlaamabhodlela eziphuzo asetshenziswa kanye kuphela (isib. iziphuzo ezibandayo, iziphuzo zezemidlalo, amanzi, njll.) amabhodlela okugcoba (isib. isaladi yokugqoka, i-ketchup, uwoyela, njll.), amabhodlela amavithamini, amabhodlela ebhotela lamakinati

Kuyini? I-Polyethylene terephthalate (PETE noma i-PET) iyipulasitiki elula eyenziwe ukuthi iqine kancane noma iqine okwenza imelane kalula nokushaywa, futhi isize ekuvikeleni ukudla noma uketshezi ngaphakathi kwephakheji.

Isetshenziswa kanjani? Fizinkomishi zepulasitiki zezinga elihleivame ukusetshenziswa ekupakisheni ukudla kweziphuzo ezibandayo, iziphuzo zezemidlalo, amanzi asetshenziswa kanye kuphela, i-ketchup, i-salad dressing, amavithamini, amabhodlela kawoyela wemifino kanye nezitsha zebhotela lamantongomane.
