Octadecenylsuccinic Anhydride CAS 28777-98-2 yog dab tsi?

Octadecenylsuccinic Anhydride (ODSA) yog ib yam khoom siv tshuaj lom neeg zoo uas siv dav hauv kev lag luam sib zog. Hauv kev lag luam ua ntawv, nws yog siv los ua tus neeg sawv cev ntsuas qhov nruab nrab los txhim kho kev ua haujlwm tsis muaj dej, lub zog tensile, kev tiv thaiv kev sib txhuam, kev dawb, kev opacity ntawm daim ntawv thiab txhim kho qhov chaw ib puag ncig tshuaj lom neeg ntawm cov txheej txheem ua ntawv. Feem ntau, cov txheej txheem siv yog isomerize alpha olefins thiab tom qab ntawd teb nrog maleic anhydride los tsim nws.

Daim Ntawv Thov

1. Octadecenyl succinic anhydride (ODSA) yog ib qho tshuaj uas ua rau muaj kev cuam tshuam ntau heev, feem ntau yog siv rau kev ntsuas emulsification hauv cov chaw ua ntawv. Nws muaj cov pob txha olefin tsis muaj roj uas txuas nrog succinic anhydride, thiab feem ntau yog tsim tawm hauv ob kauj ruam: thawj zaug, cov olefin ncaj lossis cov ceg tsis muaj roj raug isomerized los ntawm kev hloov pauv ob npaug; tom qab ntawd, cov tshuaj sib xyaw olefin isomeric reacts nrog maleic anhydride, thiab cov khoom siv raw ASA tau los ntawm kev ntxiv cov tshuaj thiab kev ua kom zoo sib xws. ASA yog kua ntawm chav tsev kub thiab muaj kev khaws cia zoo, uas yog vim nws cov teebmeem coagulation thiab flocculation, uas tau ua tiav los ntawm kev tswj hwm tus nqi thiab kev sib txuas ntawm emulsifiers, stabilizers, promoters thiab cov khoom pab khaws cia. Txhawm rau txhim kho kev khaws cia ntawm ASA ntawm cov fibers, quaternary ammonium cationic starch, polyacrylamide (kev pab khaws cia), methylene dithiocyanate (kev khaws cia) thiab cationic polymers uas muaj polyamines feem ntau yog siv los ua cov neeg sawv cev txhawb nqa.
2. Tsis tas li ntawd xwb, octadecenyl succinic anhydride (ODSA) kuj siv ua tshuaj nruab nrab thiab ua lub luag haujlwm tseem ceeb hauv kev tsim tshuaj. Nws cov khoom siv tshuaj lom neeg muaj zog thiab nws tuaj yeem koom nrog ntau yam tshuaj lom neeg los tsim lwm yam tshuaj, uas ua rau nws siv dav hauv ntau qhov chaw lag luam.
3. Hauv kev xaus, octadecenyl succinic anhydride tsis yog tsuas yog siv los ua tus neeg sawv cev hauv kev lag luam ntawv xwb, tab sis kuj yog ib qho tseem ceeb hauv kev lag luam tshuaj lom neeg, qhia txog nws daim ntawv thov dav thiab qhov tseem ceeb hauv kev lag luam tshuaj lom neeg.
