Nā lepili paʻa ponoʻī PET a me ka ʻokoʻa PVC

I ka wā e pili ana i nā lepili paʻa ponoʻī, pono nā mea a pau e noʻonoʻo mua i ka PET a me PVC, akā pehea ka nui o kāu ʻike e pili ana i nā lepili i hana ʻia me PET a me PVC? I kēia lā, e hōʻike wau iā ʻoe:

ʻokoʻa 1
ʻOkoʻa ke ʻano o ka mea maka:
ʻO PVC, ʻo ia hoʻi, polyvinyl chloride, ʻo ka waihoʻoluʻu kumu he melemele liʻiliʻi a ʻālohilohi.
ʻO PET, ʻo ia hoʻi, polyethylene terephthalate, maikaʻi loa ka mālamalama.
ʻOkoʻa ka ikaika o nā mea maka:
ʻO PVC, ʻo ia hoʻi, polyvinyl chloride, ʻoi aku ka maikaʻi o ka mālamalama ma mua o ka polyethylene a me ka polystyrene kiʻekiʻe, akā ʻoi aku ka maikaʻi ma mua o ka polyethylene. Hoʻokaʻawale ʻia i ka polyvinyl chloride palupalu a paʻakikī e like me ka nui o nā mea hoʻololi i hoʻohana ʻia. He palupalu a ʻoʻoleʻa ka huahana palupalu, a manaʻo ʻia ʻo ia ka paʻa. ʻOi aku ka ikaika o ka huahana paʻakikī ma mua o ka polyethylene kiʻekiʻe kiʻekiʻe haʻahaʻa haʻahaʻa, akā haʻahaʻa ma mua o ka polypropylene, a ʻo ke keʻokeʻo e hana ʻia ma ka piko.
ʻO ka PET, ʻo ia hoʻi, polyethylene terephthalate, ʻoi aku ka maikaʻi o ka ikaika compressive a me ka ductility ma mua o ka polyethylene a me ka polyvinyl chloride, a ʻaʻole maʻalahi e haki.
ʻOkoʻa ka hoʻohana ʻana i nā mea maka:
ʻO PVC, ʻo ia hoʻi, nā huahana maʻamau o ka polyvinyl chloride: nā papa, nā paipu, nā kāmaʻa kāmaʻa, nā mea pāʻani, nā puka makani a me nā puka, nā ʻili kelepona, nā mea kākau, etc.
ʻO PET, ʻo ia hoʻi, ka hoʻohana maʻamau o ka polyethylene terephthalate: ʻike pinepine ʻia i nā lepili huahana e koi ai i ka wai kiʻekiʻe, alkali-resistant, chemical-resistant, heat-resistant a me nā waiwai ʻē aʻe, i hoʻohana ʻia no nā lako lumi lumi, nā huahana mālama ʻili, nā hale like ʻole. nā mea hana, nā huahana mechanical, etc.

1. ʻAʻole hiki ke hana hou ʻia ka PVC, akā hiki ke hana hou ʻia ka PET;
2. Inā hoʻohana ʻoe i nā ʻōmole PET a me nā lepili PVC, pono ʻoe e wehe i nā lepili PVC i ka wā e hana hou ai i nā hue; ʻoiai ʻaʻole pono e wehe ʻia nā lepili PET;
3. He mau waiwai dielectric maikaʻi ka PET, me ka maikaʻi anti-fouling, anti-scratch, kiʻekiʻe wela kū'ē a me nā mea'ē aʻe;
4. He mau waiwai like ko PVC a me ka PET. ʻOi aku ka maikaʻi o ka maʻalahi a me ka ʻoluʻolu ma mua o PET, akā ʻoi aku ka maikaʻi o ka degradability o PVC a he hopena maikaʻi ʻole ia i ka pale ʻana i ke kaiapuni.
5. He PET keʻokeʻo maʻamau ka PET a i ʻole PET transparent, a hiki ke hana ʻia i ke gula a i ʻole ke kala kālā, he nani loa ke nānā aku.
6. Loaʻa i nā lepili PET nā waiwai mechanical maikaʻi, ka ikaika o ka hopena, kaʻaila a me ka momona. ʻOi aku ka ikaika o ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa ma mua o ka nui o nā plastic, no laila ua hana ʻia nā kiʻi kīhini a mākou e ʻike pinepine ai me ka PET + alumini foil.
7. He maikaʻi ka ʻike a me ka palupalu maikaʻi ʻo PET ma lalo o 25u. Hoʻohana nui ʻia ia no nā kaʻa kaʻa a me nā decals kaʻa a me kekahi mau hōʻailona wehewehe huahana uila. Hoʻohana nui ʻia ka PET keʻokeʻo i nā lepili kelepona kelepona paʻa, etc.
8. ʻO ka ʻokoʻa nui mai ka PVC ʻo ia ka maikaʻi ʻole o ka wela a ua maʻalahi ka ʻelemakule e ka māmā, ka wela a me ka oxygen. Eia kekahi, hoʻohui pinepine ʻia nā mea hoʻohui ʻona i ka wā o ka hana hana PVC.

PET: paʻakikī, paʻakikī, ikaika kiʻekiʻe, ʻālohilohi ka ʻili, pili kaiapuni, ʻākala a me nā ʻāpana kala. ʻO ka hemahema, ʻoi aku ka paʻakikī o ka hoʻopaʻa ʻana i ka wela wela kiʻekiʻe PET a ʻoi aku ka maikaʻi o ke kumukūʻai ma mua o PVC. Hoʻololi pinepine ʻia kēia mea e ka PVC e nā mea hoʻohana e koi ana i nā huahana maikaʻi a me ka pale o ke kaiapuni. Hoʻohana pinepine ʻia nā mea PET e hana i nā hue plastik, pahu pahu meaʻai, etc.
PVC: He mea maʻa mau i hoʻohana ʻia he palupalu, paʻakikī, a me ka plastic. Hiki ke hana ʻia i ke aniani a me nā kala like ʻole. Hoʻohana pinepine ʻia ʻo PVC Transparent e hoʻopili i nā mea uila, nā mea hoʻonaninani, nā mea pāʻani, nā makana, a me nā huahana ʻē aʻe.
