Cellulose acetate ke sesebelisoa se feto-fetohang se nang le mefuta e mengata ea likopo. Indastering ea koae, cellulose acetate tow ke eona ntho e ka sehloohong e tala bakeng sa lisefe tsa lisakerete ka lebaka la ts'ebetso ea eona e ntle ea ho sefa. E boetse e sebelisoa indastering ea lifilimi le polasetiki bakeng sa ho etsa lifilimi tsa lifoto, liforeimi tsa lipono le lithulusi tsa lisebelisoa. Ntle le moo, cellulose acetate e sebetsa e le sesebelisoa sa bohlokoa bakeng sa li-membrane, ho kenyelletsa le li-membrane tsa filtration le likarolo tsa reverse osmosis, ka lebaka la ho kenella ha eona hantle le ho khetha. Ka biodegradability ea eona le ho ikamahanya le maemo, cellulose acetate e ntse e tsoela pele ho bapala karolo ea bohlokoa tlhahisong ea setso le lits'ebetsong tsa sejoale-joale tsa tikoloho.
Mokhoa oa ho Filtration oa Cellulose Acetate
1. Tokisetso ea Raw Material & Acetylation
Tshebetso e qala kamakhasi a lehongselulose, e hloekisitsoeng ho tlosa lignin, hemicellulose le litšila tse ling. Joale cellulose e hloekisitsoeng e sebetsanoa le eonaacetic acid, acetic anhydride, le acatalystho hlahisa cellulose acetate esters. Ka ho laola tekanyo ea ho kenya sebaka, limaraka tse fapaneng tse kang diacetate kapa triacetate li ka fumanoa.
2. Ho Hloekisa & Spinning Tharollo Tokiso
Ka mor'a acetylation, motsoako oa karabelo ha o fokotsehe, 'me lihlahisoa li tlosoa. Acetate ea cellulose ea hlatsuoa, e omisitsoe ebe e qhibiliha ka haremotsoako oa acetone kapa acetone - metsiho etsa tharollo ya ho bilika ka homogeneous. Nakong ena, tharollo e ntse e tsoela peletlhoekisoho felisa likaroloana tse sa tsitsang le li-gel, ho netefatsa ho tsitsisa le botsitso.
3. Fiber Formation & Finishing

Li-filaments lia bokelloa, lia otlolloa, 'me li etsoa hore e be khoele kapa khoele e tsoelang pele. Liphekolo tsa morao-rao tse kang ho otlolla, ho crimping, kapa ho qeta li sebelisoa ho ntlafatsa thepa ea fiber, e etsa hore e tšoanelehe bakeng sa lits'ebetso.koaesefehla, masela, le likhoele tse khethehileng.

SCY Series filthara pampiri
Pampiri ena ea sefe, e nang le selulose le sebopeho sa cationic resin, e sebetsa ka ho khetheha bakeng sa ho sefa litharollo tsa cellulose acetate. E fana ka matla a phahameng a mechine, porosity e tsitsitseng, le ho tlosoa ha litšila tse ka tšeptjoang. Lintho tse tlaase tsa polyamide epoxy resin (<1.5%) li tiisa ho lumellana le tšireletseho ka ho sebetsa ha cellulose acetate, ho thusa ho tlosa likaroloana tse ntle, li-gel, le litšila tse sa tsitsang ha li ntse li boloka botsitso ba lik'hemik'hale le ho lumellana le lijo le litekanyetso tsa tšireletso ea meriana.
