Amabhodlela e-PET ne-PETG asetshenziswa kabanzi ekugcinweni nasekuthuthweni kwe-serum, imidiya yesiko, ama-enzyme neminye imikhiqizo.Uma kuqhathaniswa nezinto ze-PET, amabhodlela enziwe ngezinto ze-PETG anezinzuzo eziningi.
✦ Isakhiwo samakhemikhali:
Igama lamakhemikhali e-PET: i-polyethylene terephthalate;
Igama lamakhemikhali le-PETG: i-polyethylene terephthalate copolymer;
I-PETG iyinhlangano yamakhemikhali ethuthukisiwe esekelwe ku-PET - i-PETG iwuhlobo lwe-PET Copolymer, isithako esibizwa ngokuthi i-cyclohexanedimethanol (CHDM) yengezwe phakathi nenqubo yokukhiqiza.Lokhu kuguqulwa kunikeza i-PETG izici ezihlukile zokusebenza.
✦ Mayelana nezakhiwo ezibonakalayo:
Ngenxa yezakhiwo ezahlukene zamakhemikhali, izakhiwo ezingokomzimba nazo zihlukile.Uma kuqhathaniswa nezinto ze-PET, i-PETG inokucaca okuphezulu, ukuqina okungcono kanye nokumelana nomthelela omkhulu nokumelana namakhemikhali.Futhi iphansi kune-PET mayelana nokumelana nokushisa okuphansi.Ngakho-ke, amabhodlela ayisikwele e-PETG angaqandiswa futhi ancibilike ngokuphindaphindiwe aze afike ku--70 degrees ngaphandle kokuphazamisa ukusebenza.
✦ Ngokuphathelene nezakhiwo zokuvimbela igesi:
I-PETG ibonisa ukusebenza okuhle kakhulu mayelana nezakhiwo ze-gas barrier, ikakhulukazi izakhiwo zayo zokuvimbela ngokumelene ne-nitrogen, umoya-mpilo ne-carbon dioxide.Idatha ikhonjiswe kuthebula elingezansi (1).Izakhiwo ezivimbelayo eziphezulu zenza amakhemikhali azwele kumoya-mpilo kanye ne-carbon dioxide Ukugcinwa kanye nokuthuthwa kwama-reagents kanye nama-reagents e-biological kubaluleke kakhulu ukuvimbela ukuwohloka nokwehluleka kwama-reagents.
Njengesitsha sokupakisha, i-PETG idinga isitoreji sesikhathi eside futhi inezidingo eziqinile zama-reagents nemikhiqizo ngokwayo.Ngakho-ke, kubaluleke kakhulu ukukhetha imikhiqizo efanele kanye nabakhiqizi;
I-Shandong Labio Biological Technology Co., Ltd. yethule uchungechunge lwe-10-1000ML lwe-PETG serum kanye namabhodlela emidiya yesiko ahlangabezana nezindinganiso ze-pharmacopoeia.
