Polyanionic cellulose (PAC) ehlile ke polymer, ea bohlokoa liindastering tse fapaneng, haholo ho cheka le ho hlahloba oli. Ho utloisisa bohlokoa le thepa ea polyanionic cellulose, ha re qaleng ho hlahloba sebopeho sa eona, ts'ebeliso le litlamorao makaleng a fapaneng.
Motheong oa eona, polyanionic cellulose e tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela. Cellulose ka boeona ke polysaccharide e entsoeng ka likaroloana tsa tsoekere tse hokahantsoeng ka libonto tsa β(1→4) tsa glycosidic. Tokisetso ena e etsa hore cellulose e be matla le ho tiea ha eona, e leng se etsang hore e be karolo ea bohlokoahali ea limela. Leha ho le joalo, thepa ea tlhaho ea cellulose e ka fetoloa le ho ntlafatsoa hore e lumellane le lits'ebetso tse fapaneng tsa indasteri, e leng se lebisang ho nts'etsopele ea lintho tse tsoang ho tse kang polyanionic cellulose.
Polyanionic cellulose e entsoe ka phetoho ea lik'hemik'hale ea selulose, moo lihlopha tsa hydroxyl (-OH) tse teng ka har'a molek'hule ea cellulose li nkeloang sebaka ke lihlopha tsa carboxymethyl (-CH2COOH). Phetoho ena e fana ka sebopeho sa anionic mokokotlong oa cellulose, e hlahisang polima e nang le thepa ea polyanionic. The degree of substitution (DS) e lekanya boholo ba sebaka sa carboxymethyl mokokotlong oa cellulose, e susumetsang thepa le ts'ebeliso ea polymer ka kakaretso.
E 'ngoe ea ts'ebeliso ea bohlokoahali ea polyanionic cellulose ke indastering ea oli le khase, haholo marong a ho cheka. Mekelikeli ea ho cheka, eo hangata e tsejoang e le seretse, e sebetsa merero e fapaneng nakong ea ts'ebetso ea ho cheka, ho kenyelletsa ho tlotsa, ho pholile le ho tlosa litšila. Polyanionic cellulose e eketsoa ho maro a ho cheka e le sebatli le se laolang tahlehelo ea mokelikeli.
Joaloka viscosifier, polyanionic cellulose e fana ka thepa ea rheological ho maro a cheka, e ntlafatsa bokhoni ba bona ba ho emisa likheo tsa ho cheka le ho boloka botsitso ba seliba. Boima ba limolek'hule tse phahameng tsa polymer le tlhaho ea anionic li e lumella ho theha sebopeho sa marang-rang ka har'a mokelikeli, ho eketsa viscosity le ho thibela ho theoha kapa ho tsitsisa ha lintho tse tiileng. Ho feta moo, polyanionic cellulose e bonts'a mamello e ntle ea letsoai, e etsa hore e tšoanelehe ho sebelisoa libakeng tsa ho cheka tse nang le letsoai le lengata le tloaelehileng mesebetsing ea ho cheka kantle ho naha.
Ntle le karolo ea eona e le viscosifier, polyanionic cellulose e sebetsa e le sesebelisoa sa taolo ea tahlehelo ea mokelikeli marong a chekang. Ka ho etsa kuku e tšesaane, e ke keng ea qojoa leboteng la seliba, polymer e thusa ho fokotsa tahlehelo ea mokelikeli sebopeho, ka hona ho boloka taolo e nepahetseng ea khatello le ho thibela tšenyo ea sebopeho. Thepa ena e bohlokoa bakeng sa ho ntlafatsa bokhoni ba ho cheka le ho fokotsa likotsi tsa ts'ebetso.
Ka ntle ho lekala la oli le khase, polyanionic cellulose e fumana ts'ebeliso liindastering tse ling tse fapaneng, ho kenyeletsoa meriana, lijo le litlolo. Meetsong ea litlama, e sebetsa joalo ka setlamo se kopanyang, se senyang, kapa sa viscosity ha ho etsoa letlapa le ho emisoa ka molomo. Indastering ea lijo, polyanionic cellulose e sebelisoa e le ntho e tiisang matla, stabilizer, kapa emulsifier lihlahisoa ho tloha ho li-sauces le liaparo ho ea lihlahisoa tsa lebese le lino tse tahang. Ho lumellana ha eona le tlhaho ea eona e se nang chefo e etsa hore e tšoanelehe ho sebelisoa lihlahisoa tsa tlhokomelo ea motho joalo ka litlolo, litlolo le li-shampoo, moo e sebetsang e le setei kapa se emisang.
Polyanionic cellulose e eme e le polymer e feto-fetohang e nang le ts'ebeliso e atileng ho liindasteri tse ngata. Thepa ea eona e ikhethang, e nkiloeng ho fetotsoeng ha selulose, e etsa hore e be ea bohlokoa haholo makaleng a kang oli le khase, meriana, lijo le litlolo. Ha lipatlisiso le tsoelo-pele ea theknoloji e ntse e tsoela pele, tšebeliso ea selulose ea polyanionic e lebelletsoe ho hola ho ea pele, ho kenya letsoho ntlafatsong le ts'ebetsong mafapheng a fapaneng.
