Mai i te tirohanga ariā:
PC (Polycarbonate)He kirihou mārama, kore tae tēnei, he ātaahua, he maeneene hoki te titiro. Nā te mea kāore he paitini, kāore hoki he kakara, me ōna āhuatanga pai rawa atu ki te ārai i te hihi UV me te pupuri i te makuku, he whānui te awhe pāmahana o te PC. Kāore e pakaru i te -180°C, ā, ka taea te whakamahi mō te wā roa i te 130°C, he mea tino pai mō te takai kai.
PET (Polyethylene Terephthalate) He rauemi tino mārama, he kore tae, he mārama hoki tēnei, he tino pakari. He āhua rite ki te karāhe, kāore he kakara, kāore he reka, ā, kāore he paitini. He mura ngāwari, ka puta he mura kōwhai me te taha kikorangi ina tahuna, ā, he pai hoki ōna āhuatanga ārai hau.
Mai i te tirohanga o ngā āhuatanga me ngā tono:
PCHe tino ātete ki ngā pānga, ā, he ngāwari ki te pokepoke, e āhei ai te hanga hei pounamu, hei ipu, hei ipu rānei mō ngā wai tākai pērā i ngā inu, te waipiro, me te miraka. Ko te ngoikoretanga matua o te PC ko tōna ngāwari ki te pakaru ahotea. Hei whakaiti i tēnei i te wā e hangaia ana, ka tīpakohia ngā rauemi mata parakore teitei, ā, ka tino whakahaerehia ngā tikanga tukatuka. Hei tāpiri, mā te whakamahi i ngā kapia he iti te ahotea o roto, pērā i te iti o ngā polyolefin, te nairona, te polyester rānei mō te whakaranu rewa, ka taea te whakapai ake i tōna ātete ki te pakaru ahotea me te mimiti wai.
PETHe iti te tauwehenga whānui, ā, he iti te tere whakahekenga o te hanga, 0.2% noa iho, arā, kotahi te whakatekau o ngā polyolefin, ā, he iti iho i te PVC me te nairona, ka hua ake he āhua pumau mō ngā hua. Ko tōna kaha miihini te mea pai rawa atu, me ngā āhuatanga whānui rite ki te konumohe. Ko te kaha kume o ōna kiriata e iwa ngā wā i te polyethylene, e toru ngā wā i te polycarbonate me te nairona, ko tōna kaha pānga e toru ki te rima ngā wā i te kiriata paerewa. Hei tāpiri, he āhuatanga ārai makuku me te pupuri kakara ōna kiriata. Heoi, ahakoa ēnei painga, he utu nui ngā kiriata polyester, he uaua ki te hiri wera, ā, he ngāwari ki te hiko pateko, koia te take kāore i te maha te whakamahi takitahi; he maha ngā wā ka honoa ki ngā kapia he pai ake te hiri wera hei hanga kiriata hiato.
Nō reira, ka taea e ngā pounamu PET i hangaia mā te whakamahi i te tukanga pupuhi totoro biaxial te whakamahi katoa i ngā āhuatanga o te PET, e tuku ana i te māramatanga pai, te kanapa o te mata, me te āhua rite ki te karāhe, ā, koinei ngā pounamu kirihou tino pai hei whakakapi i ngā pounamu karāhe.
