Mai kahi kuanaʻike manaʻo:
PC (Polycarbonate)He palakika aniani ʻole kēia, he ʻoluʻolu a laumania hoʻi ke nānā aku. Ma muli o kona ʻano ʻawaʻawa ʻole a ʻala ʻole hoʻi, a me kona mau waiwai pale UV a me ka mālama ʻana i ka makū maikaʻi loa, he ākea ka laulā o ka mahana o PC. ʻAʻole hiki ke haki ma -180°C a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma 130°C, e lilo ia i mea kūpono no ka hoʻopili ʻana i ka meaʻai.
PET (Polyethylene Terephthalate) He mea aniani loa kēia, ʻaʻohe kala, a moakaka hoʻi, he mea paʻakikī loa. He ʻano aniani kona, ʻaʻohe ona ʻala, ʻaʻohe ona ʻono, a ʻaʻohe ona ʻawahia. He mea lapalapa ia, e hana ana i kahi lapalapa melemele me kahi lihi polū ke puhi ʻia, a he mau waiwai pale kinoea maikaʻi kona.
Mai ka manaʻo o nā ʻano a me nā noi:
PCHe kūpaʻa maikaʻi loa kona i ka hopena a he maʻalahi hoʻi ke hoʻoheheʻe ʻia, e hiki ai ke hana ʻia i loko o nā ʻōmole, nā ipu, a me nā ʻano ipu like ʻole no nā wai hoʻopili e like me nā mea inu, ka waiʻona, a me ka waiū. ʻO ke kīnā nui o PC ʻo ia kona hiki ke nahā i ke koʻikoʻi. No ka hōʻemi ʻana i kēia i ka wā o ka hana ʻana, ua koho ʻia nā mea maka maʻemaʻe kiʻekiʻe, a ua kāohi pono ʻia nā ʻano hana like ʻole. Eia kekahi, ʻo ka hoʻohana ʻana i nā resins me ke koʻikoʻi haʻahaʻa i loko, e like me nā liʻiliʻi o nā polyolefins, nylon, a i ʻole polyester no ka hoʻohuihui ʻana i ka heheʻe, hiki ke hoʻomaikaʻi nui i kona kūpaʻa ʻana i ka nahā koʻikoʻi a me ka omo ʻana o ka wai.
PET: He haʻahaʻa kona coefficient o ka hoʻonui ʻana a me ka haʻahaʻa o ka hoʻoheheʻe ʻana o 0.2% wale nō, ʻo ia hoʻi ka hapaʻumi o nā polyolefins a ʻoi aku ka haʻahaʻa ma mua o PVC a me nylon, e hopena ana i nā ana paʻa no nā huahana. Ua manaʻo ʻia kona ikaika mechanical ʻo ia ka mea maikaʻi loa, me nā waiwai hoʻonui e like me ka alumini. ʻO ka ikaika tensile o kāna mau kiʻiʻoniʻoni he ʻeiwa manawa o ka polyethylene a ʻekolu manawa o ka polycarbonate a me ka nylon, ʻoiai ʻo kona ikaika hopena he ʻekolu a ʻelima manawa o nā kiʻiʻoniʻoni maʻamau. Eia kekahi, loaʻa i kāna mau kiʻiʻoniʻoni nā waiwai pale makū a me ka paʻa ʻala. Eia naʻe, me kēia mau pono, he pipiʻi loa nā kiʻiʻoniʻoni polyester, paʻakikī ke sila wela, a he maʻalahi i ka uila static, ʻo ia ke kumu i hoʻohana pinepine ʻole ʻia ai lākou; hoʻohui pinepine ʻia lākou me nā resins i ʻoi aku ka maikaʻi o ka sila wela e hana i nā kiʻiʻoniʻoni composite.
No laila, hiki i nā ʻōmole PET i hana ʻia me ka hoʻohana ʻana i ke kaʻina hana hoʻoheheʻe puhi biaxial ke hoʻohana piha i nā ʻano o PET, e hāʻawi ana i ka transparency maikaʻi, ka ʻōlinolino kiʻekiʻe, a me kahi hiʻohiʻona e like me ke aniani, e lilo ana lākou i nā ʻōmole plastik kūpono loa e pani i nā ʻōmole aniani.
