ʻeke ʻeke ʻeke meaʻaino kekahi o nā ʻāpana hoʻāʻo meaʻai meaʻai, ka mea nui i hana ʻia i nā mea plastik, e like me nā ʻeke ʻeke polyethylene, ʻeke ʻeke polypropylene, ʻeke ʻeke polyester, ʻeke ʻeke polyamide, ʻeke ʻeke polyvinylidene chloride, ʻeke ʻeke polycarbonate, ʻeke ʻeke polyvinyl a me nā mea ʻē aʻe. ʻeke hoʻopili mea polymer hou.
Ua ʻike ʻia e hiki ke hana ʻia kekahi mau mea ʻawaʻawa a me nā mea ʻino i ka wā o ka hana hou ʻana a me ka hana ʻana o nā huahana plastik, no laila ua lilo ka nānā ʻana i ka maikaʻi o nā ʻeke ʻeke meaʻai me ka nānā ʻana i ka maʻemaʻe i ka loulou mana koʻikoʻi.
1.Hōʻike hōʻike
Ma muli o ia mea kaʻeke ʻeke meaʻaipili pololei me ka meaʻai a mākou e ʻai ai i kēlā me kēia lā, ʻo ke kūlana mua o kāna nānā ʻana ʻo ia ka maʻemaʻe.
Me nā koena evaporation (acetic acid, ethanol, n-hexane), ka hoʻohana ʻana i ka potassium permanganate, nā metala kaumaha, a me ka hoʻāʻo decolorization.Hōʻike ke koena evaporation i ka hikiʻeke ʻeke meaʻaie hoʻokahe i nā koena a me nā metala kaumaha ke hālāwai lākou i ka vīneka, ka waina, ka aila a me nā wai ʻē aʻe i ka wā e hoʻohana ai.ʻO nā koena a me nā metala kaumaha ka hopena maikaʻi ʻole i ke olakino kanaka.Eia kekahi, e pili pono nā koena i ke kala, ka ʻala, ka ʻono a me nā ʻano meaʻai ʻē aʻe.
Kūlana nānā noʻeke ʻeke meaʻai: ʻO nā mea maka a me nā mea hoʻohui i hoʻohana ʻia i loko o nā ʻeke e hoʻokō i nā koi kūpono o ka ʻāina, a e hōʻoia i ka ʻole o ka make ʻana a i ʻole nā pōʻino ʻē aʻe e hana ʻia i ke kino kanaka.
Hōʻike degradability: hiki ke hoʻokaʻawale ʻia ke ʻano degradation o nā huahana i ke ʻano photodegradation, ʻano biodegradation a me ke ʻano degradation kaiapuni.Inā maikaʻi ka hana hoʻohaʻahaʻa, e uhaʻi ka ʻeke, ʻokoʻa a hoʻohaʻahaʻa iā ia iho ma lalo o ka hana hui o ka māmā a me nā microorganisms, a lilo i ʻōpala, e ʻae ʻia e ke kaiapuni kūlohelohe, e pale i ka pollution keʻokeʻo.
2．Pili ka ʻike
ʻO ka mea mua, pono e koʻikoʻi ka hoʻopaʻa ʻana i nā ʻeke ʻeke, ʻoi loa noʻeke ʻeke meaʻaipono e hoopaa loa ia.
ʻO ke kūlana nānā oʻeke ʻeke meaʻaie nānā pū ʻia nō hoʻi i ka nānā ʻana: ke ʻano oʻeke ʻeke meaʻaie palahalaha, me ka palaka ole, ka wela, ka ohu, ka aila naha a me na wrinkle, a e palahalaha ka sila wela a me ke sila hoopunipuni.Pono ka membrane i nā māwae, pores a me ka hoʻokaʻawale ʻana o ka papa hana.ʻAʻohe haumia e like me nā haumia, nā mea ʻē aʻe a me nā ʻaila ʻaila.
Nānā kikoʻī: ʻo kāna kikoʻī, ka laulā, ka lōʻihi a me ka mānoanoa ʻokoʻa i loko o ka laulā i ʻōlelo ʻia.
ʻO ka ho'āʻo waiwai kino a me ka mechanical: maikaʻi ka maikaʻi o kaʻeke.ʻO ka hoʻāʻo ʻana i nā waiwai kino a me ka mechanical e pili ana i ka ikaika tensile a me ka elongation i ka wā hoʻomaha.Hōʻike ia i ka hiki ke hoʻolōʻihi i ka huahana i ka wā e hoʻohana ai.Inā maikaʻi ʻole ka hiki ʻana o ka huahana, maʻalahi ka haki ʻana a me ka pōʻino i ka wā e hoʻohana ai.
N: Pehea e ʻike ai ināʻeke paʻi ʻilikahe mea ʻawaʻawa a maikaʻi ʻole paha?
A: ʻIke ʻia ma ke puhi ʻana i nā ʻeke plastik:
He maʻalahi ke puhi ʻana i nā ʻeke plastik non-toxic.Ke nānā pono ʻoe, e ʻike ʻoe he melemele ka waihoʻoluʻu o ka lapalapa ma ka wēlau a me ka cyan ma ka ʻāpana, a hāʻule ia e like me ke kukui me ke ʻala o ka paraffin.
ʻAʻole maʻalahi ka puhi ʻana i nā ʻeke plastik ʻona.E pio koke lākou ma hope o ka haʻalele ʻana i ke kumu ahi.He melemele ka piko a he ʻōmaʻomaʻo ka ʻāpana.Ma hope o ke puhi ʻana, e noho lākou i kahi ʻano palaki.
3.Nā mea ho'āʻo
ʻO ka maikaʻi o ka naʻau: nā ʻōpū, nā wrinkles, nā laina wai a me nā ao, nā ʻōpala, nā maka iʻa a me nā poloka paʻa, nā hemahema o ka ʻili, nā haumia, nā blisters, paʻa, ʻaʻole like ʻole o ka maka hope o ke kiʻiʻoniʻoni, nā ʻāpana hoʻopaʻa wela.
Ka hoʻokaʻawale ʻana o ka nui: ka lōʻihi o ka ʻeke, ka ʻokoʻa ākea, ka ʻokoʻa o ka lōʻihi, ka sila ʻana a me ka mamao o ka ʻeke.
Nā mea hoʻāʻo o nā waiwai kino a me nā mīkini: ka ikaika tensile, ke ʻano haʻihaʻi nominal, ka ikaika wela, ka haʻahaʻa haʻalulu ʻākau, ka hopena dart, ka ikaika ʻili, ka ʻeleʻele, ka hoʻoili ʻana i ka wai.
ʻO nā mea ʻē aʻe: ka hoʻāʻo ʻana i ka hana pale oxygen, ka hoʻāʻo ʻana i ke kaomi ʻeke ʻeke, ka hoʻāʻo hoʻokō ʻeke ʻeke, ka hoʻomaʻemaʻe hana hoʻomaʻemaʻe etc.
