He aha ka ʻeke ʻeke plastik

ʻO ka ʻeke ʻeke plastik kahi ʻano ʻeke ʻeke e hoʻohana ana i ka plastic i mea maka no ka hana ʻana i nā ʻatikala like ʻole i ke ola o kēlā me kēia lā. Hoʻohana nui ia i ke ola o kēlā me kēia lā a me ka hana ʻoihana, akā ʻo ka ʻoluʻolu i kēia manawa e lawe mai i ka pōʻino lōʻihi. Hana ʻia nā ʻeke ʻeke plastik maʻamau i ka polyethylene film, ʻaʻohe mea ʻawaʻawa a hiki ke hoʻohana ʻia e paʻa i ka meaʻai. Aia kekahi ʻano kiʻiʻoniʻoni i hana ʻia me ka polyvinyl chloride, ʻaʻole ia he mea ʻawaʻawa, akā ʻo nā mea hoʻohui i hoʻohui ʻia e like me ke kumu o ka kiʻiʻoniʻoni he mea pōʻino pinepine ia i ke kino o ke kanaka a loaʻa kekahi ʻano o ka toxicity. No laila, ʻaʻole kūpono kēia ʻano kiʻiʻoniʻoni a me nā ʻeke plastik i hana ʻia no ka paʻa ʻana i ka meaʻai.

Hiki ke hoʻokaʻawale ʻia nā ʻeke ʻeke plastik i OPP, CPP, PP, PE, PVA, EVA, nā ʻeke hui, nā ʻeke co-extrusion, etc. e like me kā lākou mau mea.

Nā pono
CPP
ʻAʻohe mea ʻawaʻawa, hui pū ʻia, ʻoi aku ka maikaʻi o ka ʻike ma mua o ka PE, a haʻahaʻa iki i ka paʻakikī. He palupalu ke ʻano, me ka ʻike o PP a me ka palupalu o PE.
PP
He haʻahaʻa ka paʻakikī i ka OPP, hiki ke hoʻolōʻihi ʻia (ʻelua ala ʻaoʻao) ma hope o ke kau ʻia ʻana i loko o kahi triangle, sila lalo a i ʻole ke sila ʻaoʻao.
PE
Aia ka formalin, akā ʻaʻole liʻiliʻi ka ʻike
PVA
ʻO ke ʻano palupalu a me ka ʻikea maikaʻi. He ʻano mea hou ia o nā mea pili kaiapuni. hehee i ka wai. Lawe ʻia nā mea maka mai Iapana mai. Piʻi ke kumukūʻai. Hoʻohana nui ʻia ia ma waho.
OPP
Maikaʻi a me ka paʻakikī paʻakikī
ʻeke huikau
He ikaika ka sila, hiki ke paʻi ʻia, ʻaʻole e hāʻule ka ʻīnika
ʻeke hoʻohuihui
Maikaʻi ka ʻike, ʻano palupalu, hiki ke paʻi ʻia

Hiki ke hoʻokaʻawale ʻia nā ʻeke ʻeke plastik i nā ʻano huahana like ʻole a me nā hoʻohana: nā ʻeke i ulana ʻia a me nā ʻeke kiʻiʻoniʻoni
ʻeke ulana
Hoʻokumu ʻia nā ʻeke i ulana ʻia me nā ʻeke polypropylene a me nā ʻeke polyethylene e like me nā mea nui;
E like me ke ʻano o ka humuhumu, ua māhele ʻia i nā ʻeke lalo me nā ʻeke a me nā ʻeke lalo me nā ʻeke.
Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻopili no nā mea kanu, nā huahana kemika a me nā mea ʻē aʻe. ʻO ke kaʻina hana nui, ʻo ia ka hoʻohana ʻana i nā mea ʻilika no ka hoʻokuʻu ʻana i ke kiʻiʻoniʻoni, ʻokiʻoki, a me ka uniaxially hohola i loko o nā filament pālahalaha, a laila ulana i nā huahana ma o ka warp a me ka weft, i kapa ʻia nā ʻeke ulana.
Nā hiʻohiʻona: ke kaumaha māmā, ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion, a me nā mea ʻē aʻe, ma hope o ka hoʻohui ʻana i ka lining kiʻiʻoniʻoni plastik, hiki ke lilo i ka moisture-proof a me ka moisture-proof; ʻO ka ukana ʻeke māmā ma lalo o 2.5kg, ʻo ka ukana ʻeke ma waena he 25-50kg, ʻo ka ukana kaumaha he 50-100kg
ʻeke kiʻiʻoniʻoni
ʻO ka mea maka o nā ʻeke kiʻiʻoniʻoni he polyethylene. ʻO nā ʻeke plastik i lawe mai i ka maʻalahi i ko mākou ola, akā ʻo ka maʻalahi i kēia manawa ua lawe mai i ka pōʻino lōʻihi.
Hoʻokaʻawale ʻia e nā mea hana: nā ʻeke plastik polyethylene kiʻekiʻe, nā ʻeke plastik polyethylene haʻahaʻa, nā ʻeke plastik polypropylene, nā ʻeke plastik polyvinyl chloride, etc.
Hoʻokaʻawale ʻia e ka hiʻohiʻona: ʻeke T-shirt, ʻeke pololei. ʻeke i hoʻopaʻa ʻia, ʻeke ʻeke palaki, ʻeke ʻano kūikawā, etc.
Nā hiʻohiʻona: Hoʻouka ʻia nā ʻeke māmā ma mua o 1kg; nā ʻeke liʻiliʻi 1-10kg; ukana kaumaha kaumaha 10-30kg; ʻOi aku ka nui o nā ʻeke pahu ma mua o 1000kg.
