kikoʻī huahana
DSTDP Powder DSTDP Pastille Ka inoa kemika: Distearyl thiodipropionate Ke kumu hoʻohālike: S(CH2CH2COOC18H37) 2 Molecular kaumaha: 683.18 CAS No.: 693-36-7 Hōʻike i nā waiwai: ʻO kēia huahana he keʻokeʻo crystalline pauka a i ʻole granules. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o benzene a me toluene. Synonym Antioxidant DSTDP, Irganox PS 802, Cyanox Stdp 3,3-Thiodipropionic acid di-n-octadecyl ester Distearyl 3,3-thiodipropionate Antioxidant DSTDP Distearyl thiodipropionate Antioxidant-STDP 3,3'-Thiodipropionic acid di-n-octadecyl ester. ʻO ka pauka crystalline/ Pastilles Ash: Max.0.10% Kekahi heheʻe: 63.5-68.5 ℃ No ka hoʻohana ʻana i ka Antioxidant DSTDP he antioxidant kōkua maikaʻi a hoʻohana nui ʻia i ka polypropylene, polyethylene, polyvinyl chloride, ABS a me ka ʻaila 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 kēia mau kumu ʻelima e koho ai: 1. Paʻa I ka wā o ka hana ʻana, pono ke kūpaʻa ka antioxidant, ʻaʻole maʻalahi ka hoʻololi ʻana, ʻaʻole i hoʻokaʻawale ʻia (a ʻaʻole kala ʻia), ʻaʻole decomposed, ʻaʻole i hoʻopili ʻia me nā mea hoʻohui kemika ʻē aʻe, ʻaʻole i hoʻopili ʻia me nā mea hoʻohui kemika ʻē aʻe i ka wā o ka hoʻohana ʻana a me ka wela wela. Hoʻololi ʻia nā mea ʻē aʻe ma luna o ka ʻili a ʻaʻole e hoʻopōʻino i nā mea hana hana, a pēlā aku. Hoʻokomo ʻia nā molekala Antioxidant ma waena o nā molekala polymer i ka wā o ka hoʻōla ʻana. 3. Migration ʻO ka hopena oxidation o ka hapa nui o nā huahana i loaʻa i ka papa pāpaʻu, kahi e koi ai i ka hoʻololi mau ʻana o nā antioxidants mai loko o ka huahana a i ka ʻili e hana. Eia nō 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. Hiki ke kaʻina hana Inā ʻoi aku ka nui o ka ʻokoʻa ma waena o ka helu hoʻoheheʻe ʻana o ka antioxidant a me ka laulā heheʻe o ka mea hana, ʻo ke ʻano o ka anti-oxidant drift a i ʻole ka anti-oxidant screw e hiki mai ana, e hopena i ka puʻunaue like ʻole o ka antioxidant i loko o 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 paha ka antioxidant, ʻaʻohe lepo a i ʻole ka lepo haʻahaʻa, a ʻaʻole e loaʻa nā hopena ʻino i ke kino o ke kanaka i ka wā o ka hoʻomaʻamaʻa ʻana a i ʻole ka hoʻohana ʻana, ʻaʻohe 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.
