ʻO ka Antioxidant DSTDP he antioxidant kōkua maikaʻi a hoʻohana nui ʻia i ka polypropylene, polyethylene, polyvinyl chloride, ABS a me ka aila lubricating.Loaʻa iā ia ka hoʻoheheʻe kiʻekiʻe a me ka volatility haʻahaʻa.
Hiki ke hoʻohana pū ʻia ka DSTDP me nā antioxidants phenolic a me nā mea hoʻoheheʻe ultraviolet e hana i ka hopena synergistic.
Mai ka hiʻohiʻona o ka hoʻohana ʻana i ka ʻoihana, hiki iā ʻoe ke kuhikuhi i nā kumu ʻelima e koho ai:
1. Paʻa
I ka wā o ke kaʻina hana, pono ke kūpaʻa ka antioxidant, ʻaʻole maʻalahi i ka volatilized, ʻaʻole i ʻulaʻula (a ʻaʻole kala ʻia), ʻaʻole decomposed, ʻaʻole i pane ʻia me nā mea hoʻohui kemika ʻē aʻe, a ʻaʻole i hoʻopili ʻia me nā mea hoʻohui kemika ʻē aʻe i ka wā o ka hoʻohana ʻana a me ka hana wela wela.Hoʻololi ʻia nā mea ʻē aʻe ma luna o ka ʻili a ʻaʻole e hōʻino i nā mea hana hana, etc.
2. Hoʻohālikelike
ʻAʻole polar nā macromolecules o nā polymers plastic, ʻoiai ʻo nā molekala o nā antioxidants he mau degere like ʻole o ka polarity, a ʻaʻole maikaʻi nā mea ʻelua.Hoʻokomo ʻia nā molekala Antioxidant ma waena o nā molekala polymer i ka wā o ka hoʻōla ʻana.
3. Ka neʻe ʻana
ʻO ka hopena o ka oxidation o ka hapa nui o nā huahana i hana nui ʻia i ka papa pāpaʻu, kahi e koi ai i ka hoʻololi mau ʻana o nā antioxidants mai loko o ka huahana i ka ʻili e hana.Eia naʻe, inā wikiwiki loa ka hoʻololi ʻana, maʻalahi ka volatilize i loko o ke kaiapuni a nalowale.ʻAʻole hiki ke pale ʻia kēia poho, akā hiki iā mākou ke hoʻomaka me ka hoʻolālā formula e hōʻemi i ka nalowale.
4. Ka hiki ke hana
Inā nui loa ka ʻokoʻa ma waena o ka helu heheʻe o ka antioxidant a me ka hoʻoheheʻe ʻana o ka mea hana, ʻo ke ʻano o ka anti-oxidant drift a i ʻole ka anti-oxidant screw e kū mai, e hopena i ka hāʻawi like ʻole o ka antioxidant i ka huahana.No laila, i ka wā e emi iho ai ka helu heheʻe o ka antioxidant ma mua o ka wela o ka hoʻoili ʻana ma mua o 100 °C, pono e hana ʻia ka antioxidant i masterbatch o kahi ʻano ʻano, a laila hui pū me ka resin ma mua o ka hoʻohana ʻana.
5. Palekana
Pono e loaʻa nā hana hana i loko o ke kaʻina hana, no laila, ʻaʻohe mea ʻawaʻawa a haʻahaʻa loa ka antioxidant, ʻaʻohe lepo a i ʻole ka lepo haʻahaʻa, a ʻaʻohe hopena ʻino i ke kino o ke kanaka i ka wā o ka hoʻohana ʻana a i ʻole ka pollution. i ke kaiapuni a puni.ʻAʻohe pōʻino i nā holoholona a me nā mea kanu.
ʻO nā antioxidants kahi lālā koʻikoʻi o ka polymer stabilizers.I ke kaʻina o ka hoʻoili waiwai, pono e uku ʻia i ka manawa, ke ʻano a me ka nui o nā antioxidants i hoʻohui ʻia e pale aku i ka hemahema ma muli o nā kumu kūlohelohe.
