ʻO nā kīʻaha wai i hoʻohana pinepine ʻia, akā he nui nā ʻano kīʻaha.Ma keʻano o nā mea kīʻaha, nā kīʻaha aniani, nā kīʻaha enamel, nā kīʻaha seramika, nā kīʻaha plastik, nā kīʻaha kila kila, nā kīʻaha pepa, nā kīʻaha thermos, nā kīʻaha olakino, etc. Pehea e koho ai i kahi kīʻaha wai palekana kūpono no ka inu?
1. Ke kīʻaha kīʻaha: e koho i ka plastik meaʻai
Ua aloha nui ʻia nā kīʻaha plastik e nā poʻe he nui ma muli o ko lākou ʻano loli, nā kala ʻālohilohi, a me nā ʻano o ka makaʻu ʻole i ka hāʻule.He kūpono loa lākou no nā mea hoʻohana waho a me nā limahana keʻena.Ma ka ʻōlelo maʻamau, he hōʻailona ko lalo o ke kīʻaha plastik, ʻo ia ka helu ma ka triangle liʻiliʻi.ʻO ka mea maʻamau ʻo "05", ʻo ia hoʻi, ʻo ka mea o ke kīʻaha he PP (polypropylene).ʻO ke kīʻaha i hana ʻia me ka PP he kūpaʻa wela maikaʻi, ʻo ka helu hoʻoheheʻe he 170 ° C ~ 172 ° C, a paʻa mau nā waiwai kemika.Ma waho aʻe o ka hoʻopili ʻia ʻana e ka ʻakika sulfuric concentrated a me ka waikawa nitric concentrated, ʻano paʻa ia i nā reagents kemika ʻē aʻe.Akā ākea ka pilikia me nā kīʻaha plastik maʻamau.ʻO ka plastik kahi mea kemika polymer.Ke hoʻohana ʻia kahi kīʻaha plastik e hoʻopiha ai i ka wai wela a i ʻole ka wai paila, ua maʻalahi ka polymer a hoʻoheheʻe ʻia i loko o ka wai, he mea pōʻino i ke olakino kanaka ma hope o ka inu ʻana.Eia kekahi, ʻo ka microstructure o loko o ka plastic he nui nā pores, kahi e hūnā ai i ka lepo, a e hānau ka bacteria inā ʻaʻole i hoʻomaʻemaʻe pono ʻia.No laila, he mea koʻikoʻi ke koho ʻana i nā kīʻaha palaka no ke koho ʻana i nā mea plastik, a pono e koho ʻia nā meaʻai i kūpono i nā kūlana ʻāina.ʻO ia ka mea PP.
2. Ke kīʻaha ceramic: koho i ke kala underglaze pū kekahi
ʻO nā kīʻaha wai seramika waihoʻoluʻu he ʻoluʻolu loa, akā ʻoiaʻiʻo, aia nā pōʻino huna nui i kēlā mau pena ʻālohilohi.Hoʻopili pinepine ʻia ka paia o loko o kahi kīʻaha seramika kala ʻulaʻula me kahi papa aniani.Ke hoʻopiha ʻia ke kīʻaha aniani i ka wai hoʻolapalapa a i ʻole nā mea inu me ka waika kiʻekiʻe a me ka alkalinity, ʻo kekahi alumini a me nā mea ʻawaʻawa kaumaha ʻē aʻe i loko o ka glaze e maʻalahi a hoʻoheheʻe ʻia i loko o ka wai.I kēia manawa, ke inu ka poʻe i ka wai me nā mea kemika, e pōʻino ke kino o ke kanaka.Ke hoʻohana nei i nā kīʻaha seramika, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā kīʻaha kala maoli.Inā ʻaʻole hiki iā ʻoe ke pale aku i ka hoʻowalewale o ke kala, hiki iā ʻoe ke hele a hoʻopā i ka ʻili kala.Inā maʻemaʻe ka ʻili, ʻo ia ke ʻano o ka waihoʻoluʻu underglaze a i ʻole ka waihoʻoluʻu underglaze, kahi palekana;Aia kekahi hanana o ka hāʻule ʻana, ʻo ia hoʻi he kala on-glaze, a ʻoi aku ka maikaʻi ʻaʻole kūʻai.
3. Nā kīʻaha pepa: Pono e hoʻohana liʻiliʻi nā kīʻaha pepa
I kēia manawa, kokoke i kēlā me kēia ʻohana a me nā ʻāpana e hoʻomākaukau i kahi kīʻaha pepa kīʻaha hiki ke hoʻohana ʻia e hoʻokahi kanaka a hoʻolei ʻia ma hope o ka hoʻohana ʻana, ʻo ia ka maʻemaʻe a maʻalahi hoʻi, akā ʻo ia kīʻaha maʻamau e hūnā i nā pilikia he nui.ʻEkolu ʻano kīʻaha pepa ma ka mākeke: ʻo ka mea mua i hana ʻia me ka pepa keʻokeʻo, ʻaʻole hiki ke paʻa i ka wai a me ka ʻaila.ʻO ka lua he kīʻaha pepa i uhi ʻia i ka wax.ʻOiai ka lōʻihi o ka mahana o ka wai ma mua o 40 ° C, e hoʻoheheʻe ka wax a hoʻokuʻu i ka carcinogenic polycyclic aromatic hydrocarbons.ʻO ke kolu o nā ʻano he kīʻaha pepa-pike.Inā ʻaʻole maikaʻi nā mea i koho ʻia a ʻaʻole maikaʻi paha ka ʻenehana hana ʻana, e hoʻololi ʻia nā hoʻololi ʻana i ka wā o ka polyethylene wela hoʻoheheʻe ʻia a i ʻole ka hamo ʻana i nā kīʻaha pepa, e hopena i nā carcinogens.I mea e hoʻonui ai i ka paʻakikī a me ka paʻakikī o nā kīʻaha, hoʻohui ʻia nā plasticizer i nā kīʻaha pepa.ʻAʻole hiki ke hōʻoiaʻiʻo ʻia nā kūlana maʻemaʻe inā kiʻekiʻe loa ka dosage a i ʻole hoʻohana ʻia nā plasticizers kānāwai.
4. Glass: pono a palekana e pale i ka pahū
ʻO ka koho mua no nā aniani inu he aniani, ʻoi aku hoʻi no nā keʻena a me nā mea hoʻohana home.ʻAʻole maopopo a nani wale ke aniani, akā ma waena o nā mea a pau o ke aniani, ʻo ke aniani ka mea olakino a palekana.Hana ʻia ke aniani i nā silicates inorganic, ʻaʻole i loaʻa i nā kemika organik i ka wā o ke kaʻina puhi.Ke inu ka poʻe i ka wai a i ʻole nā mea inu ʻē aʻe mai ke aniani, ʻaʻole pono lākou e hopohopo no ka inu ʻana o nā kinikona i loko o ko lākou ʻōpū.;A maʻalahi ka ili aniani a maʻalahi hoʻi e hoʻomaʻemaʻe, a ʻaʻole maʻalahi ka hua bacteria a me ka lepo ma ka paia o ke kīʻaha, no laila ʻo ia ka mea olakino a palekana loa no ka poʻe e inu i ka wai mai ke aniani.Eia naʻe, pono e hoʻomaopopo ʻia e makaʻu loa ke aniani i ka hoʻonui ʻana a me ka hoʻohaʻahaʻa ʻana, a ʻo ke aniani me ka haʻahaʻa haʻahaʻa loa ʻaʻole pono e hoʻopiha koke ʻia me ka wai wela e pale ai i ka pohā.
