Ma ke ola o kēlā me kēia lā, e ʻike mākou he nui nā huahana plastik e loaʻa i kekahi ʻala ke hoʻohana mua ʻia.No ka laʻana, e loaʻa i kekahi mau huahana polyethylene a me polypropylene maʻamau ka ʻala ʻala i ka hoʻomaka ʻana o ka hoʻohana ʻana, a e emi loa ka ʻala ma hope o ka wā hoʻohana., No ke aha e honi ai kēia mau mea plastik?
ʻO kēia mau ʻala i loko o nā plastics ka mea nui mai nā mea hoʻohui i hoʻohui ʻia i loko o ke kaʻina hana plastic.ʻO kēia ma muli o ka hoʻohui ʻana o nā solvents a me kahi liʻiliʻi o nā mea hoʻomaka a me nā mea hoʻohui ʻē aʻe i ka wā o ka polymerization o ka polyethylene a me ka polypropylene resins.Ma hope o ka holoiʻana, ka kānana, a me nā mea'ē aʻe, i kekahi manawa e waihoʻia kahi'āpana liʻiliʻi o nā mea kōkua i'ōleloʻia aʻe nei, aʻo ka mea hou aku, e mau ana kahi liʻiliʻi o ka polymer haʻahaʻa haʻahaʻa i loko o ka resin.I ka wā o ka hana ʻana a me ka hana ʻana i nā huahana plastik, e hōʻike ʻia kēia mau mea i nā wela kiʻekiʻe e pakele ai i kahi ʻala maʻa ʻole a noho ma ka ʻili o ka huahana.
Eia kekahi, e hoʻohui kekahi mau mea hana i kekahi turpentine i mea kōkua kala i ka wā e waiho ai i ka plastic.Inā hoʻohana nui ʻia, e pakele pū ka ʻala o ka turpentine mai ka huahana.Nalo mālie a ʻaʻohe hopena i ke olakino kanaka.Eia nō naʻe, inā kaumaha loa ka ʻala a lōʻihi ka lōʻihi, e loaʻa mau ana ka hopena i ke olakino kanaka.
No laila, i ke kūʻai ʻana i nā huahana plastik, pono mākou e koho i nā huahana plastik me nā mea maka palekana, maikaʻi maikaʻi a me ke kumu palekana kiʻekiʻe.
