Pehea e koho ai i ka antioxidant kūpono?

Pehea eKohokaAkūponoAantioxidantʻAʻole anei?

ʻO ke koho ʻana i ka antioxidant kūpono he hana nui ia e hoʻomaikaʻi ai i ke kūpaʻa, ke ʻano a me ka hana o ka polymer. Pono kēia i ka noʻonoʻo piha ʻana i nā mea he nui e like me nā waiwai kemika o ka polymer ponoʻī, nā kūlana hana, ke kaiapuni hoʻohana hope loa a me nā lula palekana kaiapuni.

Nā Polyolefins(e like me ka polyethylene a me ka polypropylene) e maʻalahi i ka hoʻohaʻahaʻa oxidative thermal, e koi ana i nā antioxidants mua (e like me nā phenols) e hopu i nā radical manuahi a me nā antioxidants kōkua (e like me nā phosphites) e hoʻokaʻawale i ka hydroperoxide.

PVCʻO ka hoʻohaʻahaʻa ʻana o ka PVC ma muli o ka ionization, a i hoʻohālikelike ʻia me nā polyolefins, ʻoi aku ka liʻiliʻi o ka noi o nā mea hana PVC no nā antioxidants. I kēia manawa, ʻo nā antioxidants i hoʻohana pinepine ʻia no PVC e komo pū meAO1076, AO2246, a pēlā aku.

Nā palakiko ʻenekinia(PA, PC, PPS) i hana ʻia ma ke ʻano maʻamau i nā mahana kiʻekiʻe a koi ʻianā antioxidants pale welae pale aku i ka melemele a me ka nalowale ʻana o ka ikaika.

①No nā kūlana hana wela kiʻekiʻe (>280 ℃), he mea kūpono ke koho i nā ʻano me ka haʻahaʻa haʻahaʻa a me ke kūpaʻa wela kiʻekiʻe.

②No ka hoʻolaha ʻana i waho no ka manawa lōʻihi, pono kahi ʻōnaehana anti-UV synergistic, e like me nā pūhui phenolic a meNā mea hoʻopū UV.

③E makaʻala i ka hoʻohālikelike a pale i ka ua. Eia kekahi, ʻoi aku ka nāwaliwali o ka pale kala o nā antioxidants amine.

④ʻO ka hui pū ʻana o ka antioxidant nui a me ka antioxidant kōkua hiki ke hoʻomaikaʻi nui i ka hopena anti-kahiko.

I ka hōʻuluʻulu manaʻo, ʻaʻole lawa ka hoʻohana ʻana i nā antioxidants wale nō e hoʻoponopono i nā ʻano noi like ʻole, a ʻo ka hoʻonohonoho ʻana o nā mea hoʻohui he nui kahi koho maikaʻi aʻe.

E leka uila mai iā mākou no ka ʻike hou aku!
