Octadecenylsuccinic Anhydride (ODSA) yog ib qho siv dav hauv kev lag luam teeb pom kev zoo tshuaj raw khoom. Hauv kev lag luam papermaking, nws yog siv los ua tus neeg sawv cev nruab nrab los txhim kho cov dej tsis zoo, lub zog tensile, kev puas tsuaj, xim dawb, opacity ntawm daim ntawv thiab txhim kho cov tshuaj ib puag ncig ntawm cov txheej txheem papermaking. Feem ntau, cov txheej txheem siv yog isomerize alpha olefins thiab tom qab ntawd hnov mob nrog cov txiv neej anhydride los tsim nws.

1. Octadecenyl succinic anhydride (ODSA) yog ib qho tshuaj reactive sizing tus neeg sawv cev, feem ntau yog siv rau ntawm qhov chaw emulsification sizing hauv ntawv mills. Nws muaj cov pob txha olefin unsaturated txuas nrog succinic anhydride, thiab feem ntau yog tsim nyob rau hauv ob kauj ruam: ua ntej, lub unsaturated ncaj saw los yog ceg olefins yog isomerized los ntawm ob daim ntawv cog lus hloov chaw; Tom qab ntawd, cov isomeric olefin sib tov reacts nrog maleic anhydride, thiab ASA raw khoom yog tau los ntawm kev sib ntxiv cov tshuaj tiv thaiv thiab coj refining. ASA yog kua nyob rau hauv chav tsev kub thiab muaj kev tuav pov hwm zoo, uas yog vim nws cov coagulation thiab flocculation cuam tshuam, uas yog ua tiav los ntawm kev tswj hwm thiab kev sib txuas ntawm emulsifiers, stabilizers, txhawb nqa thiab khaws cia. Txhawm rau txhim kho kev tuav pov hwm ntawm ASA ntawm fibers, quaternary ammonium cationic starch, polyacrylamide (kev pab tuav pov hwm), methylene dithiocyanate (preservative) thiab cationic polymers uas muaj polyamines feem ntau yog siv los ua tus neeg sawv cev. cov
2. Tsis tas li ntawd, octadecenyl succinic anhydride (ODSA) kuj yog siv los ua cov tshuaj nruab nrab thiab ua lub luag haujlwm tseem ceeb hauv kev tsim tshuaj. Nws cov khoom siv tshuaj 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 hom kev lag luam 2. cov
3. Hauv cov ntsiab lus, octadecenyl succinic anhydride tsis yog tsuas yog siv los ua tus neeg sawv cev sizing hauv kev lag luam papermaking, tab sis kuj yog ib qho tseem ceeb nruab nrab hauv kev lag luam tshuaj, ua kom pom nws txoj kev siv dav thiab qhov tseem ceeb hauv kev lag luam tshuaj.
