Chii chinonzi Octadecenylsuccinic Anhydride CAS 28777-98-2?

Octadecenylsuccinic Anhydride (ODSA) chinhu chinoshandiswa zvakanyanya muindasitiri yemakemikari akapfava. Muindasitiri yekugadzira mapepa, inoshandiswa sechinhu chinosimudzira saizi isingapindi mvura, simba rekudhonza, kuramba kukwesha, kuchena, kupenya kwepepa uye kuvandudza mamiriro emakemikari ekugadzira mapepa. Kazhinji, nzira inoshandiswa ndeyekuisa alpha olefins muchimiro che isomerize uye wobva waita ne maleic anhydride kuti ibudiswe.

Kushandiswa

1. Octadecenyl succinic anhydride (ODSA) chinhu chinoshanda zvakanyanya pakukura kwemasero, chinoshandiswa zvikuru pakugadzira saizi ye emulsification panzvimbo yacho mumapepa ekugadzira. Chine skeleton ye olefin isina kuzara yakabatana ne succinic anhydride, uye inowanzogadzirwa mumatanho maviri: chekutanga, ma olefin asina kuzara akabatana ne double bond displacement; ipapo, musanganiswa we isomeric olefin unosangana ne maleic anhydride, uye ASA raw material inowanikwa kuburikidza nekuwedzera reaction uye kunatswa kwakafanana. ASA inonyorova patembiricha yemukamuri uye ine kuchengetedza kwakanaka, izvo zvinokonzerwa ne coagulation yayo uye flocculation effects, izvo zvinowanikwa kuburikidza ne charge regulation uye bridging ye emulsifiers, stabilizers, promoters uye retention aids. Kuti iwedzere kuchengetedza kweASA pamafibers, quaternary ammonium cationic starch, polyacrylamide (retention aid), methylene dithiocyanate (preservative) uye cationic polymers dzine polyamines dzinowanzo shandiswa seanotsigira. ‌
2. Pamusoro pezvo, octadecenyl succinic anhydride (ODSA) inoshandiswawo semushonga wemakemikari uye inoita basa rakakosha mukugadzirwa kwemakemikari. Hunhu hwayo hwemakemikari hunoshanda uye inogona kutora chikamu mukuita kwakasiyana-siyana kwemakemikari kugadzira mamwe makemikari, izvo zvinoita kuti ishandiswe zvakanyanya muminda yakasiyana-siyana yemaindasitiri.
3. Muchidimbu, octadecenyl succinic anhydride haingoshandiswi semushonga wekuisa saizi chete muindasitiri yekugadzira mapepa, asiwo sechikamu chakakosha muindasitiri yemakemikari, ichiratidza kushandiswa kwayo kwakakura uye kukosha kwayo muindasitiri yemakemikari.
