Carboxymethylcellulose (CMC) , E tsejoang ka hore ke selulose gum, ke motsoako oa selulose o feto-fetohang le o sebelisoang haholo o nang le lits'ebetso tse ngata liindastering tse fapaneng.Polymer ena e qhibilihang ka metsing e tsoa ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa limela.Phuputsong ena e pharaletseng, re hlahloba sebopeho sa carboxymethylcellulose, thepa ea eona, mekhoa ea tlhahiso, le mefuta e fapaneng ea lisebelisoa ho pholletsa le lijo le lino, meriana, litlolo, masela le liindasteri tse ling.
Sebopeho sa Carboxymethylcellulose (CMC):
Carboxymethylcellulose e hlahisoa ka ho fetola selulose ka lik'hemik'hale ka mekhoa ea etherification le carboxymethylation.Liphetoho tsena li kenyelletsa ho hlahisa lihlopha tsa carboxymethyl mokokotlong oa cellulose.Tekanyo ea substitution (DS), e emelang palo e tloaelehileng ea lihlopha tsa carboxymethyl ho unit ea anhydroglucose ka selulose, e ka laoloa nakong ea ts'ebetso ea tlhahiso.Phetoho ena e fana ka thepa e khethehileng ho CMC, e etsa hore e qhibilihe ka metsing 'me e loketse mefuta e mengata ea lisebelisoa.
Lintho tse molemo tsa Carboxymethylcellulose:
1. Ho qhibiliha ha Metsi:
E 'ngoe ea litšobotsi tsa bohlokoa tsa CMC ke ho qhibiliha ha eona metsing.E qhibiliha ka metsing ho etsa tharollo e hlakileng, e hlakileng.Thepa ena e bohlokoa ka ho khetheha liindastering tseo ho tsona ho khethoang metsoako ea metsi.
2. Taolo ea Viscosity:
CMC e tsejoa ka bokhoni ba eona ba ho laola viscosity ea tharollo ea metsi.Sena se etsa hore e be moemeli oa bohlokoa oa ho teteka lits'ebetsong tse fapaneng, ho tloha ho lihlahisoa tsa lijo ho ea ho metsoako ea meriana.
3. Ho tsitsisa le ho Emisa:
CMC e sebetsa joalo ka stabilizer mme e ka sebelisoa ho emisa likaroloana tse tiileng mekhoeng ea mokelikeli.Sena se bohlokoa liindastering tse kang tsa lijo le tsa meriana, moo kabo e tšoanang ea metsoako e leng bohlokoa.
4. Lintho tsa ho Etsa Lifilimi:
CMC e bonts'a thepa ea ho etsa lifilimi, e etsa hore e be molemo lits'ebetsong moo ho etsoang filimi e tšesaane, e tenyetsehang e lakatsehang.Thepa ena e sebelisoa liindastering tse joalo ka masela, moo CMC e sebelisoang ho etsa boholo le lits'ebetso tsa ho qetela.
5. Biodegradability:
CMC e nkoa e le botsoalle ho tikoloho kaha e nkiloe mehloling e ka nchafatsoang hape e khona ho senyeha.Sena se tsamaellana le khatello e ntseng e hola ea lisebelisoa tse tšoarellang le tse sebetsang hantle liindastering tse fapaneng.
Mokhoa oa ho etsa Carboxymethylcellulose:
Tlhahiso ea CMC e kenyelletsa mehato e mengata, ho qala ka khetho ea mohloli oa cellulose.Wood pulp ke ntho e tloaelehileng ea ho qala, leha k'hothone le mehloli e meng e thehiloeng ho semela le eona e ka sebelisoa.Selulose e tlas'a karabelo ea alkali-catalyzed ka sodium monochloroacetate, e bakang carboxymethylation.Tekanyo ea ho kenya sebaka e laoloa ho finyella thepa e lakatsehang bakeng sa likopo tse itseng.Karabelo e lateloa ke mekhoa ea ho se nke lehlakore le ea tlhoekiso ho fumana sehlahisoa sa ho qetela sa CMC.
Lisebelisoa tsa Carboxymethylcellulose:
1. Indasteri ea Lijo le Lino:
CMC e sebelisoa haholo indastering ea lijo e le setenya, se tsitsang, le sa texturizer.E fumanoa lihlahisoa tse kang ice cream, li-sauces, li-dressings le lintho tse halikiloeng.Ka lino tse tahang, CMC e sebelisetsoa ho tsitsisa le ho emisa likaroloana tse entsoeng.
2. Meriana:
Mekhatlong ea meriana, CMC e sebetsa e le setlamo sa tlhahiso ea matlapa, e fana ka momahano ho metsoako e phofshoana.E boetse e sebelisoa e le "viscosity modifier" meriana ea mokelikeli le e le ntho e emisang ho emisa ka molomo.
3. Litlolo le Lihlahisoa tsa Tlhokomelo ea Motho:
CMC e teng linthong tse fapaneng tsa litlolo le tsa tlhokomelo ea motho, ho kenyeletsoa litlolo, litlolo, li-shampoo le sesepa sa meno.Lintho tsa eona tse teteaneng le tse tsitsitseng li kenya letsoho ho sebopeho sa kakaretso le ts'ebetso ea lihlahisoa tsena.
4. Liaparo:
Indastering ea masela, CMC e sebelisoa ts'ebetsong ea boholo, moo e fanang ka matla le bonolo ho likhoele.E boetse e sebelisoa ho qeta mekhoa ea ho etsa sebaka se boreleli le se ts'oanang holim'a masela.
5. Indasteri ea Oli le Khase:
CMC e sebelisoa ho cheka maro a indasteri ea oli le khase.E sebetsa joalo ka sekontiri le se fokotsang tahlehelo ea mokelikeli, se tlatsetsang botsitsong le tšebetsong ea maro a chekang maemong a thata a jeoloji.
6. Indasteri ea Lipampiri:
Ho etsa pampiri, CMC e sebelisoa e le thuso ea ho boloka le ho ntša metsi.E ntlafatsa ho bolokoa ha likaroloana tse ntle, tse lebisang ho boleng bo ntlafetseng ba pampiri le ho eketsa katleho mosebetsing oa ho etsa pampiri.
7. Lisebelisoa le Lihlahisoa tsa ho Hloekisa:
CMC e eketsoa ho li-detergents le lihlahisoa tsa ho hloekisa ho matlafatsa viscosity le botsitso.E kenya letsoho kabong e ts'oanang ea lisebelisoa tse sebetsang le lithuso ho thibela ho tsitsa kapa ho arohana.
8. Lipente le Mekhabiso:
CMC e sebelisoa ha ho etsoa lipente le lipente tse thehiloeng metsing.E sebetsa e le motenya, e kenyang letsoho ho ts'ebetsong e lakatsehang ea sehlahisoa nakong ea kopo.
Mekhoa le Menahano ea Bokamoso:
Ha liindasteri li ntse li tsoela pele ho fetoha, ho na le khatiso e ntseng e eketseha ea thepa e tšoarellang le e se nang tikoloho.Carboxymethylcellulose, e nkiloeng mehloling e ka nchafatsoang hape e bonts'a biodegradability, e tsamaellana le mekhoa ena.Boiteko bo tsoelang pele ba lipatlisiso le nts'etsopele bo ka tsepamisa maikutlo ho ntlafatseng lits'ebetso tsa tlhahiso le ho lekola lits'ebetso tse ncha tsa CMC liindasteri tse ntseng li hlaha.
Qetello:
Carboxymethylcellulose, ka motsoako oa eona o ikhethang oa thepa le lits'ebetso ho liindasteri tse fapaneng, e fetohile karolo ea bohlokoa ho thehoeng ha lihlahisoa tse ngata.Ho tloha ho ntlafatsa sebopeho sa lihlahisoa tsa lijo ho ea ho ntlafatsa ts'ebetso ea meriana le ho kenya letsoho boleng ba masela, CMC e bapala karolo e nang le likarolo tse ngata.Ha theknoloji e ntse e tsoela pele le tlhokahalo ea lisebelisoa tse tšoarellang le tse sebetsang li ntse li eketseha, ho tenyetseha ha carboxymethylcellulose ho e beha e le karolo ea bohlokoa tikolohong ea mahlale a thepa ea sejoale-joale.Boqapi bo tsoelang pele le tšebelisano lipakeng tsa bafuputsi, bahlahisi le basebelisi ba ho qetela ba kanna ba senola menyetla e mecha bakeng sa CMC, ho netefatsa bohlokoa ba eona le bohlokoa ba eona lilemong tse tlang.
