I kēia mau lā, hopohopo nui nā kānaka i ko lākou olakino. ʻIke pinepine kekahi poʻe i nā nūhou e pili ana kekahi poʻe e ʻai i ka lawe ʻai no ka manawa lōʻihi i nā pilikia olakino. No laila, i kēia manawa ke hopohopo nui nei ka poʻe inā he ʻeke plastik no ka meaʻai a he pōʻino paha ia i ko lākou olakino. Eia kekahi mau ala e hoʻokaʻawale ai i waena o nā ʻeke plastik no ka meaʻai a me nā ʻeke plastik maʻamau.
He mea maʻalahi ka hoʻohana ʻana i nā ʻeke plastik no ka meaʻai a me nā mea ʻē aʻe. I kēia manawa, ʻelua ʻano ʻeke plastik ma ka mākeke, hoʻokahi i hana ʻia me nā mea e like me ka polyethylene, kahi palekana a hiki ke hoʻohana ʻia no ka hoʻopili ʻana i ka meaʻai, a ʻo kekahi mea ʻawaʻawa, hiki ke hōʻino i ka ʻeke meaʻai a hiki ke hoʻohana wale ʻia. hoʻohana ʻia no ka hoʻopili maʻamau.
ʻEke no ka hoʻopaʻa ʻana i ka meaʻaiʻike nui ʻia iā mākou he mau ʻeke ʻai-ʻai, no laila ʻoi aku ka paʻakikī a me ke kūlana kiʻekiʻe no kā lākou mau mea. Hoʻohana maʻamau mākou i nā mea meaʻai, ʻaʻohe mea ʻawaʻawa, kiʻiʻoniʻoni pili i ke kaiapuni ma ke ʻano nui. A he ʻano ʻano like ʻole nā mea maka, no laila pono mākou e koho e like me nā ʻano o ka meaʻai ponoʻī i ka manawa o ka hana ʻana.
He aha ke ʻano o nā ʻeke ʻeke meaʻai?
ʻO PE ka polyethylene, a ʻo nā ʻeke plastik PE he meaʻai. ʻO PE kahi ʻano resin thermoplastic i hana ʻia me ka ethylene ma o ka polymerization. ʻAʻole ʻawaʻawa a ʻaʻohe mea ʻawaʻawa, a maikaʻi loa ke kūpaʻa haʻahaʻa haʻahaʻa (ʻo ka wela haʻahaʻa haʻahaʻa ʻo -100 ~ 70 ℃). Loaʻa iā ia ke kūpaʻa kemika maikaʻi, ka ʻakika a me ke kūpaʻa alkali, a ʻaʻole hiki ke hoʻoheheʻe ʻia i nā solvents maʻamau i ka mahana maʻamau. Loaʻa iā ia ka insulation uila maikaʻi loa a me ka haʻahaʻa wai haʻahaʻa. Hoʻokaʻawale ʻia nā ʻeke ʻeke meaʻai maʻamau i nā ʻeke ʻeke meaʻai maʻamau, ʻeke ʻeke ʻeke meaʻai, ʻeke ʻeke meaʻai inflatable, ʻeke ʻeke meaʻai paila, ʻeke ʻeke meaʻai paila, ʻeke ʻeke meaʻai hana a pēlā aku, me nā mea like ʻole. Loaʻa nā ʻeke plastik ʻano meaʻai maʻamau i ka PE (polyethylene), alumini paʻi, nylon a me nā mea hana. Loaʻa i nā ʻeke plastik ʻano meaʻai kekahi mau hiʻohiʻona maʻamau i mea e hōʻoia ai i ka meaʻai he hou a ʻaʻohe maʻi a me ka pala. ʻO kekahi, ʻo ia ka hoʻopaʻa ʻana i ka mea hoʻoheheʻe organik, ka momona, ke kinoea, ka mahu wai a pēlā aku; ʻO ka mea ʻē aʻe ka loaʻa ʻana o ke kūpaʻa permeability maikaʻi loa, ka pale ʻana i ka wai, ke kū anuanu, ka pale wela, ka pale ʻana i ka māmā a me ka insulation, a he nani ke ʻano; ʻO ke kolu he maʻalahi ka hana a me ke kumukūʻai hana haʻahaʻa; ʻO ka hā ka loaʻa ʻana o ka ikaika maikaʻi, ʻoi aku ka ikaika o nā ʻeke ʻeke plastik i kēlā me kēia paona paona, ʻaʻohe hopena a maʻalahi hoʻi e hoʻololi.
ʻEke ʻeke meaʻai a me nā ʻeke plastik maʻamau e ʻike i ke ʻano
ʻO ke ʻano o ka nānā ʻana i ka waihoʻoluʻu, ʻo nā ʻeke plastik palekana he keʻokeʻo keʻokeʻo keʻokeʻo, translucent, e ʻike ʻia kēia plastic i ka lubricated, me he mea lā he wax ka ʻili, akā ʻo ke kala o nā ʻeke plastik ʻona he melemele hamster, ʻoluʻolu liʻiliʻi.
ʻO ke ʻano kaiapuni wai, hiki iā ʻoe ke hoʻokomo i ka ʻeke ʻeke i loko o ka wai, e kali i kahi manawa e hoʻokuʻu ai, e ʻike ʻia ʻo ka hāʻule i lalo o ka wai he mau ʻeke plastik ʻona, palekana ka ʻaoʻao.
ʻano ahi. Hiki ke puhi i nā ʻeke plastik palekana. I ka wā e ʻā ana, loaʻa iā lākou ka lapalapa uliuli e like me ka aila kukui, aia ke ʻala o ka paraffin, akā liʻiliʻi loa ka uahi. A ʻaʻole hiki ke puhi ʻia nā ʻeke plastik ʻona, melemele ka lapalapa, ʻā a hoʻoheheʻe ʻia ka siliki, e loaʻa kahi ʻala hoʻonāukiuki e like me ka waika hydrochloric.
ala ala. ʻO ka ʻōlelo maʻamau, ʻaʻohe ʻala ʻē aʻe nā ʻeke plastik palekana, akā, aia kahi ʻala ʻono a hoʻonanea, ma muli paha o ka hoʻohana ʻana i nā mea hoʻohui a i ʻole ka maikaʻi ʻole.
