He aha ke ʻano o nā ʻeke ʻeke meaʻai kūpono

I kēia lā i ka ʻoihana meaʻai,ʻeke ʻeke meaʻaihe hapa pono ole.ʻO ka maikaʻi oʻeke ʻeke meaʻaie pili pono i ka maikaʻi o nā huahana, no laila he aha ke ʻano o nā ʻeke ʻeke meaʻai i kūpono?E wehewehe pōkole kāua.

1. ʻAʻole pono e loaʻa nā hemahema i ka helehelena e like me nā ʻōhū, nā kaha wai, nā perforations, a me nā mea ʻē aʻe, a ʻo ka laula, ka lōʻihi, a me ka mānoanoa o nā kikoʻī e pono i loko o ka palena ʻokoʻa.
2. ʻO nā waiwai kino, me ka ikaika tensile a me ka elongation i ka wā haʻihaʻi, e hōʻike ana i ka hiki o ka huahana ke kū i ka wā e hoʻohana ai.Inā kūpono ʻole kēia mea, hiki i ka ʻeke ʻeke meaʻai (kiʻiʻoniʻoni) ke haki i ka wā e hoʻohana ai.poino.
3. Hana maʻemaʻe, me nā koena evaporation (acetic acid, ethanol, n-hexane), ka hoʻohana ʻana i ka potassium permanganate, nā metala kaumaha, a me nā hoʻāʻo decolorization.Hōʻike nā koena evaporation i ka hiki ʻana o nā koena a me nā metala kaumaha i hoʻoheheʻe ʻia mai loko o nā ʻeke ʻeke meaʻai i ka wā e hālāwai ai lākou i ka vīneka, ka waina, ka ʻaila 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 hoʻopili pololei nā koena i ke kala a me ka ʻala o ka meaʻai., ʻono a me nā ʻano meaʻai ʻē aʻe.
4. ʻO ka hana hoʻohaʻahaʻa, e like me nā ʻano like ʻole o ka hōʻino ʻana o ka huahana, hiki ke hoʻokaʻawale ʻia i ke ʻano photodegradable, biodegradable type, a me ke ʻano degradation kaiapuni.Hōʻike ka hana hoʻohaʻahaʻa i ka hiki o ka huahana ke ʻae ʻia e ke kaiapuni ma hope o ka hoʻohana ʻia a hoʻolei ʻia.Inā maikaʻi ka hana hoʻohaʻahaʻa, e haki ka ʻeke (kiʻiʻoniʻoni), ʻokoʻa a hoʻohaʻahaʻa iā ia iho ma lalo o ka hana hui ʻana o ka māmā a me nā microorganisms, a ma hope e lilo i ʻōpala, he ʻano kūlohelohe.Ua ʻae ʻia;inā ʻaʻole maikaʻi ka degradability, ʻaʻole e ʻae ʻia e ke kaiapuni, no laila e hana ʻia ai ka "pollution keʻokeʻo".

ʻO nā mea nānā o ke kiʻi hoʻopihapiha meaʻai ka mea nui:
Pono ka helehelena e maʻemaʻe, me ka ʻole o nā ʻōpala, nā kuni, nā ʻōpū a me nā wrinkles, a ʻo ka sila wela e maʻemaʻe a me nā sila hoʻopunipuni.ʻAʻole e loaʻa nā māwae, nā pores a me ka hoʻokaʻawale ʻana o ka papa hoʻohui.ʻAʻohe haumia, nā mea ʻē aʻe a me nā ʻaila a me nā mea haumia ʻē aʻe.ʻAʻole e ʻala ʻokoʻa ka wai i loko o ka ʻeke, ʻala, turbidity a me ka ʻeleʻele.
