He aha ke ʻano o ka plastic PE? ʻO kahi wehewehe kikoʻī o nā ʻano, nā waiwai a me nā noi o ka polyethylene (PE)
He aha ka PE plastic?
"He aha ka PE plastic?" Nīnau pinepine ʻia kēia nīnau, ʻoi loa ma ka ʻoihana kemika a me nā ʻoihana hana. ʻO PE, a i ʻole polyethylene, he thermoplastic i hana ʻia e ka polymerizing ethylene monomer. E like me kekahi o nā plastics maʻamau, ʻike ʻia ʻo PE no kāna mau hoʻohana like ʻole a me ka laulā o nā noi. ʻO kāna kumu kūʻai haʻahaʻa, ka plasticity kiʻekiʻe a me ke kūpaʻa kemika e lilo ia i mea waiwai nui i ka ʻoihana hou.
Nā ʻano o nā Plastics PE
Hoʻokaʻawale ʻia nā plastics Polyethylene (PE) i ʻekolu mau ʻāpana: polyethylene haʻahaʻa haʻahaʻa (LDPE), polyethylene kiʻekiʻe (HDPE) a me ka polyethylene haʻahaʻa haʻahaʻa laina (LLDPE).
Polyethylene Māmā Haʻahaʻa (LDPE)
ʻO ka LDPE he polyethylene me ka hoʻopuehu nui ʻana, e hopena i kahi haʻahaʻa haʻahaʻa. Hiki ke maʻalahi a ʻikea a hoʻohana mau ʻia i ka hana ʻana i nā ʻeke plastik, kiʻi ʻoniʻoni a me nā mea hoʻopili maʻalahi.

Polyethylene Māmā Kiʻekiʻe (HDPE)
He ʻoi aku ka paʻa o ka molecular HDPE ma mua o LDPE, ʻoi aku ka nui o ka nui a me ka wela a me ka hopena.

Linear Low Density Polyethylene (LLDPE)
Hoʻohui ʻo LLDPE i ka maʻalahi o ka LDPE a me ka ikaika o HDPE me ke kūpaʻa maikaʻi a me ka pale ʻana i ka waimaka. Hoʻohana pinepine ʻia e hana i nā kiʻi ʻoniʻoni ʻoi aku ka paʻakikī, e like me nā kiʻi ʻoniʻoni ʻōpala a me nā ʻoihana ʻoihana.

Nā waiwai o ka plastic PE
ʻO ka hoʻomaopopo ʻana i "he aha ka plastic ka PE" pono e nānā hohonu i kāna mau waiwai waiwai. ʻO ka polyethylene nā hiʻohiʻona like ʻole:
Paʻa kemika maikaʻi loa
He kūpaʻa maikaʻi ka polyethylene i ka hapa nui o nā kemika e like me nā waikawa, nā alkali a me nā paʻakai. No kēia kumu, hoʻohana pinepine ʻia nā mea PE i nā pahu kemika a me nā pipeline.

ʻO ke kūpaʻa hopena kiʻekiʻe
Loaʻa i ka polyethylene kiʻekiʻe a me ka haʻahaʻa haʻahaʻa ke kūʻē i ka hopena kiʻekiʻe, i mea maikaʻi loa no ka hoʻopili ʻana a me ka mālama ʻana.

Ka hoʻopololei uila
ʻO ka polyethylene kahi mea hoʻokalakupua uila maikaʻi loa a hoʻohana pinepine ʻia i ka uhi waho o nā uea a me nā kaula e hōʻoia i ka hana palekana o nā mea uila.

Hoʻohana ʻia i nā plastik PE
ʻO ka nui o nā noi no ka polyethylene e pane piha i ka nīnau "He aha ka PE? Ma muli o kāna mau waiwai like ʻole, noho nā mea PE i kahi kūlana koʻikoʻi ma nā ʻoihana he nui.
Hoʻopili ʻia
He kuleana koʻikoʻi ka Polyethylene i ka ʻoihana hoʻopili, ʻoi aku hoʻi i ka ʻāpana o ka hoʻopili maʻalahi, kahi ʻeke plastik PE a me nā kiʻiʻoniʻoni ka mea maʻamau o ka PE i ke ola o kēlā me kēia lā.

Kapili & Paipu
Hoʻohana nui ʻia ka polyethylene kiʻekiʻe kiʻekiʻe (HDPE) i ka ʻoihana kūkulu hale no ka paipu, ka wai a me nā paipu hoʻoili kinoea ma muli o kona ʻano ʻino a me ka hoʻopaʻa ʻana.

Mea kūʻai a me ka hale
Hoʻohana pū ʻia nā plastik PE i nā huahana mea kūʻai aku i kēlā me kēia lā e like me nā mea pāʻani, nā mea hale a me nā pahu mālama. ʻAʻole palekana wale kēia mau huahana a ʻaʻohe mea ʻawaʻawa, akā hiki ke hana hou ʻia e hōʻemi i ka pollution kaiapuni.

Ka hopena
No ka hōʻuluʻulu ʻana, ʻo ka pane i ka nīnau "He aha ka PE plastic?" ʻO ka pane i kēia nīnau e uhi i ka ʻokoʻa o nā mea polyethylene a me kā lākou ākea ākea. Ma ke ʻano he mea paʻa paʻa, malleable a me nā kumu kūʻai haʻahaʻa, he kuleana koʻikoʻi ka PE ma nā ʻano āpau o ka nohona hou. ʻO ka hoʻomaopopo ʻana i kona mau ʻano like ʻole a me nā waiwai hiki ke kōkua iā mākou e hoʻohana maikaʻi i kēia mea e holomua ai ka ʻoihana a me ke kūlana o ka nohona.
