ʻO ka nīnau "Hiki i ka acetone ke hoʻoheheʻe i ka plastik?"he mea maʻamau, lohe pinepine ʻia ma nā hale, nā hale hana, a me nā pōʻai ʻepekema.ʻO ka pane, e like me ka mea i ʻike ʻia, he mea paʻakikī, a e ʻimi kēia ʻatikala i nā loina kemika a me nā hopena i hoʻokumu i kēia ʻano.

acetonehe mea hoʻohuihui maʻalahi no ka ʻohana ketone.Loaʻa iā ia ke ʻano kemika C3H6O a ua kaulana ʻo ia no kona hiki ke hoʻoheheʻe i kekahi mau ʻano plastic.ʻO ka plastik, ma ka ʻaoʻao ʻē aʻe, he huaʻōlelo ākea e uhi ana i kahi ākea o nā mea hana kanaka.ʻO ka hiki o ka acetone ke hoʻoheheʻe i ka plastic ma muli o ke ʻano o ka plastic i komo.

Ke hoʻopili ʻia ka acetone me kekahi ʻano plastic, hiki mai kahi hopena kemika.Hoʻopili ʻia nā molekala plastik i nā molekole acetone ma muli o ko lākou ʻano polar.Ke alakaʻi nei kēia mea hoʻowalewale i ka liquefied o ka plastic, ka hopena i ka hopena "melting".Eia naʻe, he mea nui e hoʻomaopopo ʻaʻole kēia he kaʻina hoʻoheheʻe maoli akā he pilina kemika.

ʻO ke kumu nui ma ʻaneʻi ʻo ka polarity o nā molekole i pili.ʻO nā molekele polar, e like me ka acetone, loaʻa ka puʻunaue maikaʻi a hapa ʻole i loko o ko lākou hale.ʻAe kēia iā lākou e launa pū me nā mea polar e like me kekahi ʻano plastic.Ma o kēia hoʻopili ʻana, hoʻopau ʻia ke ʻano molekala o ka plastic, e alakaʻi ana i kona "hoʻoheheʻe".

I kēia manawa, he mea nui ia e hoʻokaʻawale i waena o nā ʻano plastik like ʻole i ka wā e hoʻohana ai i ka acetone ma ke ʻano he solvent.ʻOiai ua maʻalahi loa kekahi mau plastic e like me ka polyvinyl chloride (PVC) a me ka polyethylene (PE) i ka huki polar o ka acetone, ʻo nā mea ʻē aʻe e like me ka polypropylene (PP) a me ka polyethylene terephthalate (PET) ʻaʻole liʻiliʻi.ʻO kēia ʻokoʻa o ka reactivity ma muli o ke ʻano o nā hana kemika a me nā polarities o nā plastics like ʻole.

ʻO ka loaʻa ʻana o ka plastic i ka acetone hiki ke hopena i ka pōʻino mau a i ʻole ka hōʻino ʻana o ka mea.ʻO kēia no ka mea hiki i ka hopena kemika ma waena o ka acetone a me ka plastic ke hoʻololi i ke ʻano molekala o ka hope, e alakaʻi ana i nā loli i kona mau waiwai kino.

ʻO ka hiki i ka acetone ke "hoʻoheheʻe" i ka plastic ma muli o ka hopena kemika ma waena o nā molekala acetone polar a me kekahi ʻano o ka plastic polar.Hoʻopilikia kēia hopena i ke ʻano mole o ka plastic, e alakaʻi ana i kona liquefaction.Eia nō naʻe, he mea nui e hoʻomaopopo i ka loaʻa ʻana o ka acetone i ka wā lōʻihi e hopena i ka pōʻino mau a i ʻole ka hōʻino ʻana o ka mea plastik.
