ʻO ka Octadecenylsuccinic Anhydride CAS 28777-98-2
ʻO ka Octadecenylsuccinic Anhydride (ODSA) kahi mea maka kemika maikaʻi loa i hoʻohana nui ʻia no ka ʻoihana māmā. I ka ʻoihana hana pepa, hoʻohana ʻia ia ma ke ʻano he mea hoʻohui kūlike e hoʻomaikaʻi nui i ka hana wai ʻole, ka ikaika tensile, ke kū'ē ʻana i ka abrasion, ke keʻokeʻo, ka opacity o ka pepa a hoʻomaikaʻi i ke kaiapuni kemika o ke kaʻina hana pepa. ʻO ka maʻamau, ʻo ke kaʻina hana i hoʻohana ʻia e isomerize i nā alpha olefins a laila e hana me ka maleic anhydride e hana iā ia.

1. ʻO Octadecenyl succinic anhydride (ODSA) kahi mea hoʻonui nui i ka reactive, i hoʻohana nui ʻia no ka hoʻonui ʻana i ka emulsification ma kahi i nā hale wili pepa. Loaʻa iā ia kahi iwi olefin unsaturated i hoʻopili ʻia i ka succinic anhydride, a hana pinepine ʻia i ʻelua mau ʻanuʻu: ʻo ka mua, ua isomerized ʻia nā olefins kaulahao pololei a lālā paha ma o ka hoʻoneʻe ʻana o ka pilina pālua; a laila, hana ka hui olefin isomeric me ka maleic anhydride, a loaʻa ka mea maka ASA ma o ka hoʻohui ʻana a me ka hoʻomaʻemaʻe like ʻana. He wai ka ASA ma ka mahana o ka lumi a he paʻa maikaʻi kona, ma muli o kona hopena coagulation a me ka flocculation, i hoʻokō ʻia ma o ka hoʻoponopono ʻana i ka uku a me ke alahaka o nā emulsifiers, stabilizers, promoters a me nā mea kōkua paʻa. I mea e hoʻonui ai i ka paʻa ʻana o ASA ma nā fibers, hoʻohana pinepine ʻia ka quaternary ammonium cationic starch, polyacrylamide (mea kōkua paʻa), methylene dithiocyanate (mea mālama) a me nā polymers cationic e loaʻa ana nā polyamines ma ke ʻano he mau mea kākoʻo.
2. Eia kekahi, hoʻohana ʻia ka octadecenyl succinic anhydride (ODSA) ma ke ʻano he mea waena kemika a he kuleana koʻikoʻi kāna i ka hana kemika. He hana ikaika kona mau waiwai kemika a hiki iā ia ke komo i nā ʻano hana kemika like ʻole e hana i nā kemika ʻē aʻe, kahi e hoʻohana nui ʻia ai i nā ʻoihana like ʻole2.
3. I ka hōʻuluʻulu manaʻo, ʻaʻole hoʻohana wale ʻia ka octadecenyl succinic anhydride ma ke ʻano he mea hoʻonui i ka ʻoihana hana pepa, akā he mea waena koʻikoʻi hoʻi i ka ʻoihana kemika, e hōʻike ana i kona noi ākea a me ke koʻikoʻi i ka ʻoihana kemika.
200kgs/pahu a i ʻole i hoʻopilikino ʻia e like me nā koi a ka mea kūʻai aku
