He kirihou PET kua whakarerekētia te PETG. He kirihou mārama, he copolyester kore-kiriata, ko te comonomer PETG e whakamahia whānuitia ana ko te 1,4-cyclohexanedimethanol (CHDM), ko te ingoa katoa ko te polyethylene terephthalate-1,4-cyclohexanedimethanol. Ki te whakatauritea ki te PET, he nui ake ngā comonomer 1,4-cyclohexanedimethanol, ā, ki te whakatauritea ki te PCT, he nui ake ngā comonomer ethylene glycol. Nō reira, he tino rerekē te mahi a te PETG i tā te PET me te PCT. He tino mārama ōna hua, ā, he tino pai te ātete ki te pānga, he tino pai mō te hanga hua mārama matotoru.
Hei rauemi tākai,PETGkei a ia ngā painga e whai ake nei:
1. He mārama ake, he whakawhiti mārama tae atu ki te 90%, ka taea te tae atu ki te mārama o te plexiglass;
2. He pakari ake, he mārō hoki, he ātete pai ki te rakuraku, ki te ātete pānga me te pakari;
3. Mō te ātete matū, te ātete hinu, te ātete huarere (te kōwhai), te kaha miihini, me te ātete ārai ki te hāora me te mamaoa wai, he pai ake hoki te PETG i te PET;
4. Kāore he paitini, he pono te mahi akuaku, ka taea te whakamahi mō te kai, te rongoā me ētahi atu takai, ā, ka taea te whakahoromata mā te whakamahi i ngā hihi gamma;
5. E tutuki ana i ngā whakaritenga o te tiaki taiao, ā, ka taea te hangarua i runga i te ōhanga me te watea. Ina tahuna te para, kāore e puta he matū kino e whakararu ana i te taiao.
Hei rauemi tākai,PETkei a ia ngā painga e whai ake nei:
1. He pai ngā āhuatanga miihini, ko te kaha pānga he 3~5 ngā wā i ērā atu kiriata, he pai te ātete takai, ā, he pai tonu te pakari i te -30°C;
2. Ātete ki te hinu, te ngako, te waikawa waimeha, te kawakore waimeha, me te nuinga o ngā whakarewa;
3. He iti te uruhanga o te hau me te kohu wai, he pai te ātete ki te hau, te wai, te hinu me te kakara;
4. Kāore he paitini, kāore he reka, he akuaku, he haumaru hoki, ka taea te whakamahi tika ki roto i ngā takai kai;
5. He iti ake te utu o ngā rauemi mata i te PETG, ā, he mama te taumaha o te hua kua oti, ā, he ātete ki te pakaru, he mea watea mō ngā kaihanga ki te whakaiti i ngā utu whakaputa me te kawe, ā, he teitei te mahi utu whānui.
He pai ake te PETG i te PET noa i roto i ngā āhuatanga mata pēnei i te āheinga tā me te piri. He rite te mārama o te PETG ki te PMMA. He kaha ake te pakeke, te maeneene, me ngā āheinga tukatuka muri o te PETG i te PET. Ki te whakatauritea ki te PET, he mārama hoki te ngoikoretanga o te PCTG, arā, he tino teitei te utu, arā, e 2~3 ngā wā o te PET. I tēnei wā, ko te nuinga o ngā rauemi pounamu takai kei te mākete he rauemi PET te nuinga. Ko ngā āhuatanga o ngā rauemi PET he māmā, he mārama teitei, he ātete ki te pānga, ā, kāore e pakarukaru.
Whakarāpopototanga: He putanga whakapai ake a PETG o te PET, he mārama ake, he pakari ake, he ātete pai ake ki ngā pānga, ā, he nui ake te utu.
