I-PETG iyipulasitiki ye-PET eguquliwe. Ipulasitiki esobala, i-copolyester engeyona i-crystalline, i-PETG evame ukusetshenziswa i-comonomer yi-1,4-cyclohexanedimethanol (CHDM), igama eligcwele i-polyethylene terephthalate-1,4-cyclohexanedimethanol. Uma kuqhathaniswa ne-PET, kunama-comonomers amaningi we-1,4-cyclohexanedimethanol, futhi uma kuqhathaniswa ne-PCT, kunama-ethylene glycol comonomers amaningi. Ngakho-ke, ukusebenza kwe-PETG kuhluke kakhulu kulokho kwe-PET ne-PCT. Imikhiqizo yayo isobala kakhulu futhi inokumelana nomthelela omuhle kakhulu, ifaneleka kakhulu ukwenza imikhiqizo ebonisa ngale enezindonga eziwugqinsi.
Njengempahla yokupakisha,I-PETGinezinzuzo ezilandelayo:
1. Ukucaca okuphezulu, ukukhanya okudluliswayo kufika ku-90%, kungafinyelela obala kwe-plexiglass;
2. Inokuqina okuqinile nobulukhuni, ukumelana okuhle kakhulu nokuklwebheka, ukumelana nomthelela kanye nokuqina;
3. Mayelana nokumelana kwamakhemikhali, ukumelana nowoyela, ukumelana nesimo sezulu (okuphuzi) ukusebenza, amandla emishini, kanye nokusebenza kwesithiyo ku-oxygen kanye nomhwamuko wamanzi, i-PETG nayo ingcono kune-PET;
4. Ukusebenza kwenhlanzeko okungenabo ubuthi, okuthembekile, kungasetshenziselwa ukudla, imithi nokunye ukupakisha, futhi kungabulawa inzalo ngemisebe ye-gamma;
5. Ihlangabezana nezidingo zokuvikelwa kwemvelo futhi ingaphinda isetshenziswe ngokonga futhi kalula. Lapho udoti ushiswa, azikho izinto eziyingozi ezibeka imvelo engozini ezizokhiqizwa.
Njengempahla yokupakisha,I-PETinezinzuzo ezilandelayo:
1. Inezici ezinhle zemishini, amandla omthelela angama-3 ~ 5 izikhathi zamanye amafilimu, ukumelana nokugoqa okuhle, futhi kusenokuqina okuhle ku--30 ° C;
2. Imelana namafutha, amafutha, i-asidi ehlanjululwe, i-alkali ehlanjululwe, kanye nezincibilikisi eziningi;
3. Igesi ephansi nomhwamuko wamanzi ukungeneka, igesi enhle kakhulu, amanzi, uwoyela kanye nokumelana nephunga;
4. Okungenabuthi, okunganambitheki, okuhlanzekile futhi okuphephile, kungasetshenziswa ngokuqondile ekupakisheni kokudla;
5. Intengo yezinto eziluhlaza ishibhile kune-PETG, futhi umkhiqizo ophelile ulula ngesisindo futhi umelana nokuphulwa, okulungele abakhiqizi ukunciphisa izindleko zokukhiqiza nezokuthutha, futhi ukusebenza kwezindleko jikelele kuphezulu.
I-PETG iphakeme kune-PET evamile ezindaweni ezingaphezulu njengokuphrinta nokunamathela. Ukubonakala kwe-PETG kuqhathaniswa ne-PMMA. Ukuqina, ukushelela, kanye namakhono angemuva kokucubungula we-PETG anamandla kune-PET. Uma kuqhathaniswa ne-PET, ukungalungi kwe-PCTG nakho kusobala, okungukuthi, intengo iphakeme kakhulu, okuyi-2 ~ 3 izikhathi ze-PET. Njengamanje, izinto eziningi zamabhodlela okupakishwa emakethe ikakhulukazi yizinto ze-PET. Izinto ze-PET zinezici zesisindo esilula, ukukhanya okuphezulu, ukumelana nomthelela futhi akuntekenteke.
Isifinyezo: I-PETG inguqulo ethuthukisiwe ye-PET, enokukhanya okuphezulu, ukuqina okuphezulu, ukumelana nomthelela ongcono, futhi yiqiniso inani eliphakeme.
