Octadecenylsuccinic Anhydride CAS 28777-98-2
Ko te Octadecenylsuccinic Anhydride (ODSA) he matū matū pai rawa atu i te ahumahi marama. I roto i te ahumahi hanga pepa, ka whakamahia hei kaihoko rahi kore ki te whakapai ake i te mahi parewai, te kaha tensile, te aukati abrasion, te ma, te opacity o te pepa me te whakapai ake i te taiao matū o te mahi pepa. I te nuinga o te wa, ko te mahi i whakamahia ko te whakamaarama i te alpha olefins katahi ka tauhohe ki te maleic anhydride hei whakaputa.

1. Ko te Octadecenyl succinic anhydride (ODSA) he kaihoko rahi tauhohenga, e whakamahia ana mo te whakaemulsification i runga i te waahi i roto i nga mira pepa. Kei roto he anga koiwi haunga kore e hono ana ki te anhydride succinic, a ka mahia i roto i nga hikoinga e rua: tuatahi, ka whakahiatohia te mekameka totika, te korefin peka ranei ma te nuku here rua; katahi, ka tauhohe te ranunga olefin isomeric ki te maleic anhydride, a ka whiwhi te ASA raw rauemi na roto i te tauhohenga taapiri me te whakamahine rite. Ko te ASA he wai i te pāmahana rūma me te pai te pupuri, na te mea ko te whakakotahitanga me nga hua o te pupuhi, ka tutuki i roto i te whakaritenga utu me te piriti o nga whakaemulsifiers, stabilizers, kaiwhakatairanga me nga awhina pupuri. Hei whakanui ake i te pupuri o te ASA ki runga i nga muka, ko te haukinia haukinia cationic starch, polyacrylamide (te awhina pupuri), te methylene dithiocyanate (whakaahua) me nga polymers cationic kei roto i nga polyamines ka whakamahia hei awhina tautoko. ;
2. I tua atu, ka whakamahia ano te octadecenyl succinic anhydride (ODSA) hei takawaenga matū me te whai waahi nui ki te hanga matū. He kaha ona ahuatanga matū, ka taea e ia te uru atu ki nga momo tauhohenga matū hei whakaputa i etahi atu matū, na reira ka whakamahia nuitia i roto i nga waahi ahumahi rereke2. ;
3. Hei whakarāpopototanga, ko te octadecenyl succinic anhydride e kore e whakamahia anake hei kaihoko rahi i roto i te ahumahi hanga pepa, engari ano he takawaenga nui i roto i te ahumahi matū, e whakaatu ana i te whanuitanga o te whakamahinga me te hiranga i roto i te ahumahi matū.
200kgs / drum ranei Whakaritea kia rite ki nga whakaritenga a te kaihoko
