Polyanionic cellulose (PAC) ehlile ke polymer, haholo-holo e tsoang ho selulose.Motsoako ona o khahlang o fumana lits'ebetso tse pharalletseng liindasteri tse fapaneng ka lebaka la thepa ea ona e ikhethang le ts'ebetso.
Sebopeho sa Polyanionic Cellulose:
Polyanionic cellulose e tsoa ho cellulose, e leng e 'ngoe ea li-polymer tsa tlhaho tse ngata ka ho fetisisa Lefatšeng.Cellulose ke polysaccharide e melang e entsoeng ka likaroloana tse pheta-phetoang tsa tsoekere tse hokahantsoeng ka libonto tsa β(1→4) tsa glycosidic.E etsa karolo ea mantlha ea sebopeho sa marako a lisele tsa semela.Polyanionic cellulose ke selulose e fetotsoeng, moo lihlopha tse ling tsa hydroxyl tsa liketane tsa cellulose li nkeloang sebaka ke lihlopha tsa anionic.Lihlopha tsena tsa anionic hangata li kenyelletsa lihlopha tsa carboxylate (-COO⁻), sulfonate (-SO₃⁻), kapa phosphate (-PO₄⁻).Ho kenyelletsoa ha lihlopha tsena tsa anionic ho fana ka ho qhibiliha ha metsi le lisebelisoa tse ling tse lakatsehang ho polymer.
Motsoako oa polyanionic cellulose:
Polyanionic cellulose hangata e entsoe ka phetoho ea lik'hemik'hale ea selulose.Mokhoa o mong o tloaelehileng o kenyelletsa ho sebetsana le selulose ka motsoako oa anhydride tlas'a maemo a khethehileng ho kenyelletsa lihlopha tsa anionic mokokotlong oa cellulose.Maemo a karabelo le mofuta oa anhydride e sebelisitsoeng li khetholla tekanyo ea ho fetola (DS) ea lihlopha tsa anionic ka ketane ea cellulose.Litekanyetso tse phahameng tsa DS li fella ka ho qhibiliha ho hoholo ha metsi le ho ntlafatsa ts'ebetso lits'ebetsong tse itseng.
Lintho tse molemo tsa Polyanionic Cellulose:
Polyanionic cellulose e bonts'a thepa e 'maloa e ikhethang e etsang hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng:
Ho qhibiliha ha Metsi: Ho kenyelletsoa ha lihlopha tsa anionic ho fana ka ho qhibiliha ha metsi ho selulose ea polyanionic, ho e lumella ho etsa litharollo tse tsitsitseng kapa li-dispersions metsing.Thepa ena e bohlokoa haholo lits'ebetsong moo ho khethoang litsamaiso tse thehiloeng ho metsi.
Phetoho ea Thickening le Rheology: Selulose ea Polyanionic e sebelisoa haholo e le sesebelisoa se teteaneng le ho fetola rheology liindastering tse fapaneng, ho kenyeletsoa lijo, meriana le lihlahisoa tsa tlhokomelo ea motho.E fana ka viscosity mme e ntlafatsa botsitso le sebopeho sa libopeho.
Taolo ea Phallo le Tahlehelo ea Mokelikeli: Liindastering tse kang ho cheka oli, polyanionic cellulose e sebelisoa bakeng sa bokhoni ba eona ba ho thella lintho tse tiileng tse emisitsoeng le ho laola tahlehelo ea mokelikeli.E thusa ho boloka botsitso ba seliba le ho ntlafatsa bokhoni ba ho cheka.
Ho lumellana: Polyanionic cellulose e lumellana le mefuta e mengata ea lik'hemik'hale tse ling le li-additives, e leng se etsang hore e be le mefuta e mengata bakeng sa ho etsoa lits'ebetsong tse fapaneng.E ka kenngoa habonolo lits'ebetsong tse fapaneng ntle le ho baka mathata a ho lumellana.
Biodegradability: Ho sa tsotellehe phetoho ea eona ea maiketsetso, selulose ea polyanionic e boloka biodegradability ea cellulose.Tšobotsi ena e bohlokoa bakeng sa ho fokotsa tšusumetso ea tikoloho, haholo-holo lits'ebetsong moo ho lahla ho leng bohlokoa.
Lisebelisoa tsa Polyanionic Cellulose:
Polyanionic cellulose e fumana lits'ebetso tse fapaneng liindastering tse ngata:
Indasteri ea Oli le Khase: Lefapheng la oli le khase, PAC hangata e sebelisoa e le sebatli le se eketsang taolo ea tahlehelo ea mokelikeli marong a chekang.E thusa ho boloka botsitso ba seliba, e ntlafatsa ho hloekisoa ha mekoti, le ho ntlafatsa bokhoni ba ho cheka.
Indasteri ea Lijo: Indastering ea lijo, PAC e sebetsa e le setei, se tsitsisa, le se hlahisang lihlahisoa tse fapaneng tse kang li-sauces, li-dressings, lihlahisoa tsa lebese le lijo tse theolelang.E ntlafatsa molomo, e matlafatsa botsitso, 'me e thibela syneresis mefuteng ea lijo.
Meriana: Polyanionic cellulose e sebelisoa mefuteng ea meriana e le setlamo, se senya, le se laoloang ho lokolla matlapa le li-capsules.E thusa ho momahano ea lipilisi, e netefatsa ho lokolloa ha lithethefatsi tse tšoanang, 'me e ntlafatsa ho latela melao ea mokuli.
Lihlahisoa tsa Tlhokomelo ea Motho: Ka lihlahisoa tsa tlhokomelo ea motho, PAC e sebelisoa e le setei, se emisang, le emulsion stabilizer lihlahisoa tse kang li-shampoo, lotions le litlolo.E ntlafatsa viscosity ea sehlahisoa, e ntlafatsa sebopeho, 'me e thibela ho arohana ha mekhahlelo.
Lisebelisuoa tsa Kaho: PAC e sebelisoa indastering ea kaho e le sesebelisoa sa ho boloka metsi, motenya, le rheology modifier mefuteng e thehiloeng ho samente joalo ka seretse, li-grouts le plaster.E ntlafatsa ts'ebetso, e fokotsa tahlehelo ea metsi, 'me e matlafatsa ho khomarela li-substrates.
Tšusumetso ea Tikoloho le Moshoelella:
Le ha cellulose ea polyanionic e fana ka melemo e fapaneng mabapi le ts'ebetso le ts'ebetso, phello ea eona ea tikoloho le eona e tlameha ho nahanoa.Joalo ka e nkiloeng ho cellulose, PAC e boloka biodegradability ea polymer ea eona ea motsoali.Sena se bolela hore tlas'a maemo a loketseng, cellulose ea polyanionic e ka aroloa ke likokoana-hloko hore e be lihlahisoa tse se nang kotsi, tse tlatsetsang ho boloka tikoloho.
Ntle le moo, mofuta o ka nchafatsoang oa cellulose joalo ka ha thepa e tala bakeng sa PAC synthesis e fana ka melemo ho latela ho fumaneha ha lisebelisoa le ho fokotseha hoa ho itšetleha ka libeso tsa khale.Boiteko bo ntse bo tsoela pele ho ntlafatsa ts'ebetso ea ho kopanya le ho ntlafatsa biodegradability ea polyanionic cellulose derivatives ho fokotsa sebaka sa bona sa tikoloho.
polyanionic cellulose ke polymer e sebetsang ka bongata e nkiloeng ho selulose, e fanang ka lits'ebetso tse fapaneng liindastering tse fapaneng.Litšobotsi tsa eona tse ikhethang, tse kenyelletsang ho qhibiliha ha metsi, matla a ho tiea, ho lumellana, le ho senyeha ha lintho tse phelang, li etsa hore e be motsoako oa bohlokoa mekhoeng e mengata.Le hoja ho fana ka melemo ea bohlokoa ea ts'ebetso, boiteko bo ntse bo tsoela pele ho netefatsa hore polyanionic cellulose le lihlahisoa tsa eona li hlahisoa le ho sebelisoa ka mokhoa o nang le boikarabelo ba tikoloho, kahoo ho leka-lekanya litlhoko tsa indasteri le lipakane tsa ts'ebetso.
