Chii chinonzi Octadecenylsuccinic Anhydride CAS 28777-98-2?

Octadecenylsuccinic Anhydride (ODSA) iindasitiri yemwenje inoshandiswa zvakanyanya yakanaka kemikari mbishi zvinhu. Muindasitiri yekugadzira mapepa, inoshandiswa senge isina kwayakarerekera saizi mumiriri kunatsiridza zvakanyanya kusapinda kwemvura, kusimba kwesimba, abrasion kuramba, kuchena, kupenya kwepepa uye kugadzirisa mamiriro emakemikari ekugadzira mapepa. Kazhinji, maitiro anoshandiswa ndeye kuisomerize alpha olefins uye obva aita ne maleic anhydride kuigadzira.

Application

1. Octadecenyl succinic anhydride (ODSA) is a very reactive sizing agent, inonyanya kushandiswa pa-site emulsification sizing muzvigayo zvemapepa. Iyo ine unsaturated olefin skeleton yakabatana ne succinic anhydride, uye inowanzo gadzirwa mumatanho maviri: kutanga, iyo isina unsaturated straight-chain kana branched olefins inomezwa nekaviri bond displacement; zvino, iyo isomeric olefin musanganiswa inobata ne maleic anhydride, uye iyo ASA mbishi zvinhu inowanikwa kuburikidza nekuwedzera reaction uye inoenderana nekunatsa. ASA imvura patembiricha yekamuri uye ine chengetedzo yakanaka, inokonzeresa coagulation uye flocculation mhedzisiro, iyo inowanikwa kuburikidza nechaji mutemo uye bhiriji emulsifiers, stabilizers, vanosimudzira uye kuchengetedza. Kuti uwedzere kuchengetwa kweASA pamafibers, quaternary ammonium cationic starch, polyacrylamide (retention aid), methylene dithiocyanate (preservative) uye cationic mapolymers ane polyamines anowanzo shandiswa sevatsigiri vamiririri. ,
2. Mukuwedzera, octadecenyl succinic anhydride (ODSA) inoshandiswawo sekemikari yepakati uye inoita basa rinokosha mukugadzirwa kwemakemikari. Yayo kemikari zvimiro inoshanda uye inogona kutora chikamu mune akasiyana makemikari maitiro kugadzira mamwe makemikari, ayo anoita kuti ishandiswe zvakanyanya mumaindasitiri akasiyana minda2. ,
3. Muchidimbu, octadecenyl succinic anhydride haingoshandiswi chete sechinhu chinopisa muindasitiri yekugadzira mapepa, asiwo seyakakosha yepakati muindasitiri yemakemikari, ichiratidza kushandiswa kwayo kwakakura uye kukosha muindasitiri yemakemikari.
