Ka nānā ʻana o ke ahi o nā plastics
ʻO ka nānā ʻana o nā plastics - macromolecules me kahi ʻano paʻakikī - he hana i hana ʻia i loko o nā laboratories kūikawā. Eia naʻe, ma ka home, hiki ke ʻike ʻia nā mea synthetic kaulana loa. Mahalo i kēia, hiki iā mākou ke hoʻoholo i ka mea a mākou e hana nei (pono nā ʻano mea like ʻole, no ka laʻana, nā ʻano kelu like ʻole no ka hui ʻana, a ʻokoʻa hoʻi nā kūlana no ka hoʻohana ʻana).
No nā hoʻokolohua, ʻo kahi kumu ahi (hiki ke lilo i kukui) a me nā ʻōpiʻi a i ʻole nā tweezers e paʻa i nā laʻana ua lawa.
Eia naʻe, e mālama kākou i nā mea e pono ai.:
- ke hoʻokō nei mākou i ka hoʻokolohua mai nā mea hiki ke ahi;
- hoʻohana mākou i nā laʻana liʻiliʻi liʻiliʻi (me kahi ʻāpana ʻaʻole ʻoi aku ma mua o 1 cm2);
- paʻa ka hāpana i loko o nā tweezers;
- ma kahi kūlana i manaʻo ʻole ʻia, e hele mai kahi lole pulu e hoʻopau i ke ahi.
I ka ʻike ʻana, e nānā pono mea hiki ke puhi (inā ʻaʻa maʻalahi a ʻaʻa paha ke wehe ʻia mai ke ahi), ke kala o ka lapalapa, ke ʻala a me ke ʻano o ke koena ma hope o ka puhi ʻana. ʻOkoʻa ke ʻano o ka laʻana i ka wā e ʻike ai a me kona ʻano ma hope o ke kī ʻana mai ka wehewehe ʻana ma muli o nā mea hoʻohui i hoʻohana ʻia (nā mea hoʻopihapiha, nā mea hoʻonaninani, nā fibers hoʻoikaika, etc.).
No nā hoʻokolohua, e hoʻohana mākou i nā mea i loaʻa i ko mākou kaiapuni: nā ʻāpana o ka foil, nā ʻōmole a me nā pūʻolo, nā paipu, a me nā mea ʻē aʻe. E kau i ka laʻana i loko o nā tweezers a waiho i loko o ka lapalapa o ke kuni:
1. Lapa (e laʻa. i loko o loko): hiki ke wela a ʻaʻole e hele i waho ke wehe ʻia mai ke kuni. He melemele ʻeleʻele ka lapalapa a ua uwahi loa. Honi mākou i ka pulupulu ahi. ʻO ke koena ma hope o ka hoʻopau ʻia ʻana he mea hoʻoheheʻe ʻia. (kiʻi 1)
2. celluloid (e laʻa. ping-pong ball): hiki ke wela a ʻaʻole e hele i waho ke wehe ʻia mai ke kapuahi. Puhi ikaika ka mea me ka lapalapa melemele ʻoniʻoni. Ma hope o ke puhi ʻana, ʻaʻohe mea i koe. (kiʻi 2)
3. PS polystyrene (e laʻa, kīʻaha yogurt): ʻā ke kukui ma hope o kekahi manawa a ʻaʻole e pio ke wehe ʻia mai ke kapuahi. He melemele-alani ka lapalapa, puka mai ka uahi ʻeleʻele mai loko mai, a palupalu a hehee ka mea. ʻOluʻolu ka ʻala. (kiʻi 3)
4. Polyethylene PE i polypropylene PP (e laʻa. ʻeke pepa): hiki ke wela a ʻaʻole hele i waho ke wehe ʻia mai ke kuni. He melemele ka lapalapa me ka halo uliuli, hehee ka mea a kahe i lalo. Ka ʻala o ka paraffin kuni. (kiʻi 4)
5. PVC polyvinyl chloride (e laʻa ka paipu): e ʻā me ka paʻakikī a hele pinepine i waho ke wehe ʻia mai ke kapuahi. He melemele ka lapalapa me ka halo ʻōmaʻomaʻo, hoʻopuka ʻia kekahi uahi a ʻoi aku ka palupalu o ka mea. ʻO ke ahi PVC he ʻala ʻala (hydrogen chloride). (kiʻi 5)
6. PMMA polymethyl methacrylate (no ka laʻana, he ʻāpana o "ke aniani organik"): ʻaʻa ke kukui ma hope o kekahi manawa a ʻaʻole pio i ka wā i wehe ʻia mai ke kapuahi. He melemele ka lapalapa me ka halo polū, i ka wā e ʻā ai, palupalu ka mea. He ala pua. (kiʻi 6)
7. Poli(ethyl terephthalate) PET (ʻOmole Soda): ʻā ke kukui ma hope o kekahi manawa a pio pinepine ke wehe ʻia mai ke kapuahi. He melemele ka lapalapa, ua uwahi iki. Hiki iā ʻoe ke honi i kahi ʻala ikaika. (kiʻi 7)
8. PA polyamide (e laʻa me ke aho lawaiʻa): e ʻā ana ke kukui ma hope o kekahi manawa a pio i kekahi manawa ke wehe ʻia mai ka lapalapa. He polū māmā ka lapalapa me ka piko melemele. hehee a kulu ka mea. Ua like ka ʻala me ka lauoho puhi. (kiʻi 8)
9. Poliveglan PC (e laʻa. CD): ʻā ke kukui ma hope o kekahi manawa a pio i kekahi manawa ke wehe ʻia mai ka lapalapa. Puhi ʻia me ka lapalapa ʻālohilohi, puhi. He hiʻona ka ʻala. (kiʻi 9)
