I-PETG yiplastiki ye-PET elungisiweyo. Iplastiki ecacileyo, i-copolyester engeyona i-crystalline, i-PETG esetyenziswa ngokuqhelekileyo i-comonomer yi-1,4-cyclohexanedimethanol (CHDM), igama elipheleleyo yi-polyethylene terephthalate-1,4-cyclohexanedimethanol. Xa kuthelekiswa ne-PET, kukho ii-comonomers ze-1,4-cyclohexanedimethanol ezininzi, kwaye xa kuthelekiswa ne-PCT, kukho i-ethylene glycol comonomers. Ngoko ke, ukusebenza kwe-PETG kwahluke kakhulu kuleyo ye-PET kunye ne-PCT. Iimveliso zayo zicace kakhulu kwaye zinefuthe elihle lokuxhathisa, ngakumbi zifanelekile ukwenza iimveliso ezicacileyo ezinodonga olungqingqwa.
Njengempahla yokupakisha,I-PETGinoncedo olulandelayo:
1. Ukukhanya okuphezulu, ukuhanjiswa kokukhanya ukuya kwi-90%, kunokufikelela kwi-transparency ye-plexiglass;
2. Inokuqina okuqinileyo kunye nobunzima, ukuxhathisa okugqwesileyo, ukuxhathisa impembelelo kunye nokuqina;
3. Ngokumalunga nokumelana neekhemikhali, ukuchasana kweoli, ukuchasana kwemozulu (iphuzi) ukusebenza, amandla omatshini, kunye nokusebenza komqobo kwi-oksijeni kunye nomphunga wamanzi, i-PETG nayo ingcono kune-PET;
4. Ukusebenza okungeyona ityhefu, okuthembekileyo kococeko, kungasetyenziselwa ukutya, amayeza kunye nokunye ukupakishwa, kwaye kunokwenziwa inzala ngemitha ye-gamma;
5. Ihlangabezana neemfuno zokukhuselwa kwendalo kwaye inokuphinda isetyenziswe ngokwezoqoqosho nangokufanelekileyo. Xa inkunkuma itshisiwe, akukho zinto ziyingozi ezibeka esichengeni okusingqongileyo ziya kuveliswa.
Njengempahla yokupakisha,I-PETinoncedo olulandelayo:
1. Ineempawu ezintle zoomatshini, amandla empembelelo ngama-3 ~ 5 amaxesha amanye amafilimu, ukuchasana kakuhle kokugoqa, kwaye kusenokuqina okuhle kwi-30 ° C;
2. Ukumelana ne-oyile, amafutha, i-asidi edibeneyo, i-alkali edibeneyo, kunye neninzi yezinyibilikisi;
3. I-gas ephantsi kunye ne-vapor vapor permeability, i-gas egqwesileyo, amanzi, i-oyile kunye nokumelana nokuvumba;
4. I-non-toxic, incasa, icocekile kwaye ikhuselekile, inokusetyenziswa ngokuthe ngqo kwipakethe yokutya;
5. Ixabiso lezinto eziluhlaza lincinci kune-PETG, kwaye imveliso egqityiweyo ilula ngesisindo kwaye ixhathisa ukuphuka, ekulungele ukuba abavelisi banciphise iindleko zokuvelisa kunye nokuthutha, kunye nokusebenza kweendleko ziphezulu.
I-PETG iphezulu kune-PET eqhelekileyo kwiipropati zomhlaba ezifana nokuprintwa kunye nokunamathela. Ukucaca kwe-PETG kuthelekiseka ne-PMMA. Ukuqina, ukuguda, kunye nezakhono zasemva kokulungiswa kwe-PETG zomelele kune-PET. Xa kuthelekiswa ne-PET, i-disadvantage ye-PCTG nayo ibonakala, oko kukuthi, ixabiso liphezulu kakhulu, eli-2 ~ 3 amaxesha e-PET. Okwangoku, uninzi lwezixhobo zokupakisha zebhotile kwimarike ubukhulu becala zizinto zePET. Izixhobo ze-PET zineempawu zobunzima bokukhanya, ukukhanya okuphezulu, ukuchasana kwempembelelo kwaye akukho buthathaka.
Isishwankathelo: I-PETG yinguqulelo ephuculweyo ye-PET, enokukhanya okuphezulu, ukuqina okuphezulu, ukumelana nempembelelo engcono, kwaye ngokuqinisekileyo ixabiso eliphezulu.
