I-PETG iyipulasitiki ye-PET eguquliwe. Iyipulasitiki esobala, i-copolyester engeyona ikristalu, i-comonomer evame ukusetshenziswa yi-PETG yi-1,4-cyclohexanedimethanol (CHDM), igama eliphelele yi-polyethylene terephthalate-1,4-cyclohexanedimethanol. Uma kuqhathaniswa ne-PET, kunezinhlobo eziningi ze-comonomer ze-1,4-cyclohexanedimethanol, futhi uma kuqhathaniswa ne-PCT, kunezinhlobo eziningi ze-ethylene glycol. Ngakho-ke, ukusebenza kwe-PETG kuhluke kakhulu kokwe-PET ne-PCT. Imikhiqizo yayo isobala kakhulu futhi inokumelana okuhle kakhulu komthelela, ikakhulukazi efanelekela ukwakha imikhiqizo esobala enodonga olujiyile.
Njengezinto zokupakisha,I-PETGinezinzuzo ezilandelayo:
1. Ukukhanya okuphezulu, ukudlulisa ukukhanya kufika ku-90%, kungafinyelela ukukhanya kwe-plexiglass;
2. Inokuqina okuqinile nokuqina, ukumelana okuhle kakhulu kokuklwebheka, ukumelana nokushayisana nokuqina;
3. Ngokuphathelene nokumelana namakhemikhali, ukumelana nowoyela, ukusebenza kokumelana nesimo sezulu (ukuphuzi), amandla omshini, kanye nokusebenza kokuvimbela umoya-mpilo nomhwamuko wamanzi, i-PETG nayo ingcono kune-PET;
4. Ukusebenza okuhlanzekile okungenabo ubuthi, okuthembekile, kungasetshenziswa ekudleni, emithini nakwezinye izinto zokupakisha, futhi kungahlanzwa ngemisebe ye-gamma;
5. Ihlangabezana nezidingo zokuvikelwa kwemvelo futhi ingaphinde isetshenziswe ngendlela engabizi futhi elula. Uma imfucuza ishiswa, akukho zinto eziyingozi ezizokhiqizwa ezibeka imvelo engozini.
Njengezinto zokupakisha,I-PETinezinzuzo ezilandelayo:
1. Inezakhiwo ezinhle zomshini, amandla okushayisana aphindwe ka-3 ~ 5 kunamanye amafilimu, ukumelana okuhle kokugoqeka, futhi isenokuqina okuhle ku--30°C;
2. Ayimelani namafutha, amafutha, i-asidi encibilikisiwe, i-alkali encibilikisiwe, kanye neziningi zezinyibilikisi;
3. Ukumuncwa okuphansi kwegesi kanye nomhwamuko wamanzi, ukumelana okuhle kakhulu kwegesi, amanzi, uwoyela kanye nephunga;
4. Ayinabo ubuthi, ayinambitheki, ihlanzekile futhi iphephile, ingasetshenziswa ngqo ekupakisheni ukudla;
5. Intengo yezinto zokusetshenziswa ishibhile kune-PETG, futhi umkhiqizo oqediwe ulula ngesisindo futhi awunqamuki, okuyinto elula kubakhiqizi ukunciphisa izindleko zokukhiqiza nezokuthutha, futhi ukusebenza kwezindleko sekukonke kuphezulu.
I-PETG ingcono kune-PET evamile ngezakhiwo zobuso ezifana nokuphrinta nokunamathela. Ukucaca kwe-PETG kufana ne-PMMA. Ubulukhuni, ukushelela, kanye namakhono okucubungula ngemuva kwe-PETG kunamandla kune-PET. Uma kuqhathaniswa ne-PET, ukungathandeki kwe-PCTG nakho kusobala, okungukuthi, intengo iphezulu kakhulu, okuphindwe kabili kuya kathathu kune-PET. Njengamanje, iningi lezinto zokupakisha zamabhodlela emakethe ikakhulukazi yizinto ze-PET. Izinto ze-PET zinezici zesisindo esilula, ukucaca okuphezulu, ukumelana nokushayisana futhi azibuthakathaka.
Isifinyezo: I-PETG inguqulo ethuthukisiwe ye-PET, enokucaca okuphezulu, ukuqina okuphezulu, ukumelana okungcono komthelela, futhi-ke intengo ephezulu.
