Octadecenylsuccinic Anhydride CAS 28777-98-2
ʻO Octadecenylsuccinic Anhydride (ODSA) he mea hoʻohana nui ʻia i ka ʻoihana māmā. I ka ʻoihana hana pepa, hoʻohana ʻia ʻo ia ma ke ʻano he mea kūʻokoʻa kūʻokoʻa e hoʻomaikaʻi maikaʻi ai i ka hana wai, ka ikaika tensile, ka pale ʻana i ka abrasion, keʻokeʻo, ka opacity o ka pepa a hoʻomaikaʻi i ke kaiapuni kemika o ke kaʻina hana pepa. ʻO ka mea maʻamau, ʻo ke kaʻina hana i hoʻohana ʻia no ka isomerize alpha olefins a laila hana me ka maleic anhydride e hana ai.

1. ʻO ka Octadecenyl succinic anhydride (ODSA) he mea hoʻohana nui ʻia, hoʻohana nui ʻia no ka nui o ka emulsification ma ka pūnaewele ma nā hale wili pepa. Loaʻa iā ia kahi iwi ʻolefin unsaturated i hoʻopili ʻia me ka anhydride succinic, a hana mau ʻia ma nā ʻanuʻu ʻelua: ʻo ka mua, ua hoʻokaʻawale ʻia ke kaulahao pololei ʻole a i ʻole nā lālā lālā i hoʻokaʻawale ʻia e ka neʻe ʻana i nā mea paʻa pālua; a laila, hoʻopili ka hui ʻolefin isomeric me ka maleic anhydride, a loaʻa ka mea maka ASA ma o ka hoʻohui ʻana a me ka hoʻomaʻemaʻe kūpono. He wai ka ASA ma ka lumi wela a he paʻa maikaʻi, ʻo ia ma muli o kāna coagulation a me nā hopena flocculation, i loaʻa ma o ka hoʻoponopono uku a me ka hoʻopili ʻana i nā emulsifiers, stabilizers, promoters a me nā mea kōkua paʻa. I mea e hoʻonui ai i ka paʻa ʻana o ka ASA ma nā fiber, hoʻohana maʻamau ka quaternary ammonium cationic starch, polyacrylamide (kokua paʻa), methylene dithiocyanate (preservative) a me nā polymers cationic i loaʻa nā polyamines i mea kākoʻo. ?
2. Eia kekahi, hoʻohana ʻia ka octadecenyl succinic anhydride (ODSA) ma ke ʻano he waena kemika a he hana koʻikoʻi i ka hana kemika. ʻO kona mau waiwai kemika a hiki iā ia ke komo i nā ʻano hoʻololi kemika e hoʻohua ai i nā kemika ʻē aʻe, kahi e hoʻohana nui ʻia ai ia ma nā ʻano ʻoihana like ʻole2. ?
3. I ka hōʻuluʻulu ʻana, ʻaʻole i hoʻohana wale ʻia ka octadecenyl succinic anhydride ma ke ʻano he mea nui ma ka ʻoihana hana pepa, akā ma ke ʻano he koʻikoʻi koʻikoʻi i loko o ka ʻoihana kemika, e hōʻike ana i kona hoʻohana ākea a koʻikoʻi i ka ʻoihana kemika.
200kgs / pahu a i ʻole i hoʻonohonoho ʻia e like me nā koi o ka mea kūʻai aku
