Maopopo anei iā ʻoe ka ʻike o nā ʻeke ʻeke meaʻai maʻamau?

Nui nā ʻano ʻeke ʻeke meaʻai i hoʻohana ʻia no ka ʻeke meaʻai, a loaʻa iā lākou kā lākou hana ponoʻī a me nā hiʻohiʻona. I kēia lā e kūkākūkā mākou i kekahi ʻike maʻamau i hoʻohana ʻia i ka ʻeke ʻeke meaʻai no kāu kuhikuhi. No laila he aha ka ʻeke ʻeke meaʻai? ʻO nā ʻeke ʻeke meaʻai maʻamau e pili ana i nā pepa plastic me ka mānoanoa o lalo o 0.25mm ma ke ʻano he kiʻiʻoniʻoni, a hoʻohana nui ʻia ka ʻeke paʻa i hana ʻia i nā kiʻiʻoniʻoni plastik i ka ʻoihana meaʻai. Nui nā ʻano ʻeke ʻeke meaʻai. ʻO lākou ke aniani, hiki ke maʻalahi, ke kūpaʻa wai maikaʻi, ke kūpaʻa ʻana o ka wai a me nā waiwai pale kinoea, ka ikaika mechanical maikaʻi, nā waiwai kemika paʻa, ke kūpaʻa aila, maʻalahi e paʻi maikaʻi, a hiki ke hoʻopaʻa ʻia i ka wela e hana i nā ʻeke. Eia kekahi, ʻo ka meaʻai maʻamau i hoʻohana ʻia i loko o nā ʻāpana ʻelua a ʻoi aku paha o nā kiʻiʻoniʻoni like ʻole, hiki ke hoʻokaʻawale ʻia i ka papa o waho, ka papa waena a me ka papa o loko e like me ke kūlana.

He aha nā koi no ka hoʻokō ʻana i kēlā me kēia papa o nā kiʻiʻoniʻoni hoʻopili meaʻai maʻamau? ʻO ka mea mua, hiki ke paʻi ʻia ke kiʻiʻoniʻoni o waho, kūʻē i ka ʻōpala, a me ke kūpaʻa waena. ʻO nā mea maʻamau i hoʻohana ʻia ʻo OPA, PET, OPP, kiʻiʻoniʻoni i uhi ʻia, a me nā mea ʻē aʻe. ʻO nā mea maʻamau i hoʻohana ʻia me BOPA, PVDC, EVOH, PVA, PEN, MXD6, VMPET, AL, a me nā mea ʻē aʻe. ʻO nā mea i hoʻohana mauʻia he CPP, PE, a me nā mea'ē aʻe. Eia kekahi, aia kekahi mau mea i ka hana hui o ka papa waho a me ka papa waena. No ka laʻana, hiki ke hoʻohana ʻia ʻo BOPA e like me ka papa o waho a me ka ʻaoʻao o loko, a hiki ke hoʻohana ʻia e like me ka papa waena e pāʻani i kahi pale a me ka pale kino.

ʻO nā hiʻohiʻona kiʻiʻoniʻoni hiki ke hoʻohana maʻamau i ka meaʻai, ma ka ʻōlelo maʻamau, pono ke kūʻē ʻana o ka mea o waho, ka pale ʻana i ka puncture, ka pale ʻana o UV, ka pale māmā, ke kū ʻana o ka aila, ke kūpaʻa kūlohelohe, ke kū anuanu, ke kūpaʻa ʻana o ke kaumaha, paʻi, paʻa wela, haʻahaʻa haʻahaʻa, haʻahaʻa. ʻO kahi ʻano o nā waiwai e like me ke ʻala, ka ʻawaʻawa ʻole, ka luster, ka ʻike, ka pale, a me nā mea ʻē aʻe; ʻO ka mea papa waena maʻamau ka hopena o ka hopena, ke kūpaʻa ʻana, ka pale ʻana i ka puncture, ka pale ʻana i ka wai, ka pale kinoea, ka paʻa ʻala, ka pale māmā, ke kūpaʻa aila, ke kūpaʻa kūlohelohe, ka wela a me ke kū anuanu. , ke kū'ēʻana i ke koʻikoʻi, ka ikaika huiʻeluaʻaoʻao, kaʻala haʻahaʻa, kaʻala haʻahaʻa, ka meaʻawaʻawaʻole, ka māmā, ka māmā-māmā a me nā mea'ē aʻe; a laila, ʻo ka mea ʻāpana o loko, me ka hoʻohui ʻana i kekahi mau waiwai maʻamau me ka ʻaoʻao o waho a me ka papa waena, loaʻa nō hoʻi kāna mau waiwai ponoʻī, pono e loaʻa ka Fragrance paʻa, haʻahaʻa adsorption a me ka impermeability. ʻO ka hoʻomohala ʻana o nā ʻeke ʻeke meaʻai i kēia manawa penei: 1. ʻO nā ʻeke ʻeke meaʻai i hana ʻia me nā mea pili i ke kaiapuni. 2. I mea e hōʻemi ai i nā kumukūʻai a mālama i nā kumu waiwai, ke ulu nei nā ʻeke ʻeke meaʻai i ka lahilahi. 3. Ke ulu nei nā ʻeke ʻeke meaʻai i ka hana kūikawā. E hoʻomau ka hoʻonui ʻana i ka hiki ke kūʻai aku i ka mākeke. ʻO nā kiʻiʻoniʻoni kiʻekiʻe me nā pono o ka hana maʻalahi, ka oxygen ikaika a me nā waiwai pale wai, a me ka hoʻomaikaʻi ʻana i ke ola o ka mālama ʻana, ʻo ia ke kumu nui o ka hoʻopili maʻalahi o nā meaʻai i ka wā e hiki mai ana.
