Carboxymethylcellulose (CMC), eo hape e tsejoang ka hore ke cellulose gum, ke polymer e sebetsang ka mefuta e mengata e nang le lits'ebetso tse fapaneng ho liindasteri tse fapaneng. Motsoako ona, o nkiloeng ho selulose, o bonts'a thepa e ikhethang e etsang hore e be ea bohlokoa haholo masimong a kang lijo, meriana, litlolo, masela le tse ling tse ngata.
Sebopeho le Thepa
Cellulose, polymer e ngata ka ho fetisisa lefatšeng, e sebetsa e le karolo ea mantlha ea meralo maboteng a lisele tsa limela. Ke polysaccharide e melang e entsoeng ka likaroloana tse pheta-phetoang tsa tsoekere tse hokahantsoeng ka libonto tsa β(1→4) tsa glycosidic. Carboxymethylcellulose ke motsoako oa selulose o fumanoang ka mokhoa oa ho fetola lik'hemik'hale.
Phetoho ea bohlokoa e kenyelletsa ho hlahisa lihlopha tsa carboxymethyl (-CH2-COOH) ho lihlopha tsa hydroxyl tsa mokokotlo oa cellulose. Ts'ebetso ena, eo hangata e etsoang ka karabelo ea etherification kapa esterification, e fana ka ho qhibiliha ha metsi le lintho tse ling tse lakatsehang ho molek'hule ea cellulose.
The degree of substitution (DS) e bolela palo e tloaelehileng ea lihlopha tsa carboxymethyl tse hokelletsoeng yuniti e 'ngoe le e 'ngoe ea anhydroglucose ketane ea cellulose. E susumetsa haholo ho solubility, viscosity, le litšobotsi tse ling tsa CMC. Litekanyetso tse phahameng tsa DS li lebisa ho solubility e kholo le litharollo tse teteaneng.
Carboxymethylcellulose hangata e fumaneha ka limaraka tse fapaneng, e 'ngoe le e' ngoe e etselitsoe ho fihlela litlhoko tse ikhethang tsa kopo. Limaraka tsena li fapana ka liparamente tse kang viscosity, degree of substitution, boholo ba likaroloana, le bohloeki.
E 'ngoe ea litšobotsi tse hlahelletseng tsa CMC ke bokhoni ba eona ba ho etsa tharollo ea viscous ka metsing. Leha e le maemong a tlase, e ka baka litlamorao tse teteaneng ka lebaka la ketane ea eona ea polymer le ho sebelisana le limolek'hule tsa metsi. Sena se etsa hore e be sesebelisoa se setle sa ho nona lits'ebetsong tse ngata.
Ho feta moo, carboxymethylcellulose e bonts'a thepa e ntle haholo ea ho etsa lifilimi, e etsa hore e be molemo bakeng sa ho etsa liphahlo le lifilimi tse nang le matla a fapaneng a ho kenella le ho sebetsa. Lifilimi tsena li fumana lits'ebetso liindastering ho tloha ho liphutheloana tsa lijo ho isa ho litlhare tsa meriana.
Lisebelisoa
Ho feto-fetoha ha carboxymethylcellulose ho tsoa ho motsoako oa eona o ikhethang oa thepa, ho etsa hore e tšoanelehe bakeng sa mefuta e fapaneng ea lits'ebetso. Tse ling tsa ts'ebeliso ea bohlokoa ea CMC li kenyelletsa:
Indasteri ea Lijo: Ka indasteri ea lijo, carboxymethylcellulose e sebetsa e le stabilizer, thickener, le emulsifier ka mefuta e mengata ea lihlahisoa. Hangata e sebelisoa lihlahisoa tsa lebese, li-sauces, li-dressings, lintho tse halikiloeng le lino tse nooang ho ntlafatsa sebopeho, molomo le botsitso ba lishelefo. Ho feta moo, CMC e sebelisoa mefuteng e se nang gluten ho etsisa sebopeho sa gluten linthong tse halikiloeng.
Meriana: CMC e fumana ts'ebeliso e pharaletseng mefuteng ea meriana ka lebaka la bokhoni ba eona ba ho matlafatsa viscosity le botsitso ba ho emisoa, li-emulsion le litlolo. E sebetsa e le se tlamella litlolo tsa letlapa, mofetoleli oa viscosity mekelikeli ea molomo, le sekontiri sa litlolo tsa lihlooho le litlolo. Ho feta moo, carboxymethylcellulose e sebelisoa e le moemeli oa ho roala matlapa, e nolofalletsang ho lokolloa ha lithethefatsi tse laoloang le ho ntlafatsa ho metsa.
Litlolo le Tlhokomelo ea Botho: Ka litlolo le lihlahisoa tsa tlhokomelo ea motho, CMC e sebetsa e le setei, se tsitsisa, le se etsang mongobo. E kenyelelitsoe ho litlolo tse kang litlolo, litlolo, li-shampoo, le sesepa sa meno ho ntlafatsa sebopeho, ho eketsa viscosity, le ho fana ka mokhoa o bonolo, o ts'oanang.
Masela: indastering ea masela, carboxymethylcellulose e sebelisoa e le sesebelisoa sa boholo ho ntlafatsa mokhoa oa ho loha le ho fana ka boima ba masela. E boetse e sebelisoa e le motenya ho li-pastes tsa khatiso ea textile ho netefatsa ho tšoana le ho hlaka ha meralo e hatisitsoeng.
Oli le Khase: CMC e sebelisoa indastering ea oli le khase e le sebali sa ho cheka seretse. E thusa ho laola tahlehelo ea mokelikeli, ho ntlafatsa ho hloekisoa ha mekoti, le ho tsitsisa likoti nakong ea ts'ebetso ea ho cheka. Ntle le moo, carboxymethylcellulose e fumana ts'ebeliso ho maro a hydraulic fracturing ho emisa li-propps le ho kenya li-additives sebopeho.
Pampiri le Packaging: indastering ea pampiri, CMC e sebetsa e le sesebelisoa sa ho roala ho ntlafatsa thepa ea pampiri, ho ntlafatsa khatiso, le ho eketsa ho hanyetsa mongobo. E boetse e sebelisoa e le sesebelisoa sa boholo ho ntlafatsa matla a pampiri le ho fokotsa ho monyela ha metsi. Ho feta moo, carboxymethylcellulose e sebelisoa ho paka thepa ho fana ka ho hanyetsa mongobo le ho ntlafatsa ho khomarela ka har'a laminate.
Kaho: Carboxymethylcellulose e sebelisoa linthong tsa kaho tse kang seretse, li-grouts le plaster ho ntlafatsa ts'ebetso, ho khomarela le ho boloka metsi. E sebetsa joalo ka mofetoleli o motenya le oa rheology, o netefatsa ts'ebeliso e nepahetseng le ts'ebetso ea lisebelisoa tsena.
Lisebelisoa tse ling: Ka ntle ho liindasteri tse boletsoeng ka holimo, CMC e fumana lisebelisoa lits'ebetsong tse fapaneng tse kang li-detergents, li-adhesives, ceramics, le ho hloekisa metsi. Ho feto-fetoha ha eona le ho tsamaellana le lintho tse ling ho etsa hore e be tlatsetso ea bohlokoa mekhoeng le lits'ebetsong tse ngata.
Bohlokoa le Melemo
Tšebeliso e atileng ea carboxymethylcellulose e ka bakoa ke melemo le melemo ea eona e mengata:
Ho feto-fetoha ha maemo: Bokhoni ba CMC ba ho sebeletsa mesebetsi e mengata, ho kenyelletsa ho tenya, ho tsitsisa, ho tlama, le ho etsa lifilimi, ho etsa hore e fetohe haholo liindasteri tse fapaneng.
Polokeho: Carboxymethylcellulose ka kakaretso e amoheloa e le e bolokehileng (GRAS) bakeng sa ho sebelisoa ke balaoli ba taolo joalo ka US Food and Drug Administration (FDA). E beha likotsi tse fokolang bophelong ba batho 'me e na le histori e telele ea tšebeliso e sireletsehileng lijong, meriana, le lihlahisoa tsa tlhokomelo ea botho.
Eco-Friendly: Joalo ka karolo e tsoang ho selulose, CMC e tsoa mehloling ea limela e nchafalitsoeng, e e etsa hore e tšoarelle tikolohong. E na le biodegradable mme ha e kenye letsoho tšilafalong ea tikoloho.
Katleho ea Litšenyehelo: Carboxymethylcellulose e fana ka tharollo e theko e tlase bakeng sa ho ntlafatsa thepa ea lihlahisoa tse fapaneng le libopeho. Litsenyehelo tsa eona tse batlang li le tlase ha li bapisoa le li-additives tse ling li etsa hore e be khetho e ratoang ho bahlahisi ba bangata.
Ts'ebetso: Thepa e ikhethang ea CMC, joalo ka bokhoni ba eona ba ho theha li-suspensions tse tsitsitseng, li-gel tse teteaneng le lifilimi tse matla, li kenya letsoho ntlafatsong ea ts'ebetso le boleng ba lihlahisoa tsa ho qetela.
Tumellano ea Taolo: Carboxymethylcellulose e lumellana le litekanyetso tsa taolo le litlhoko tsa liindasteri tse fapaneng, ho netefatsa polokeho ea sehlahisoa le boleng.
carboxymethylcellulose (CMC) e bapala karolo ea bohlokoa liindasteri tse ngata joalo ka polymer e sebetsang ka mefuta e fapaneng e nang le lits'ebetso tse fapaneng. Ho tloha ho lijo le meriana ho ea ho masela le kaho, CMC e fana ka thepa e ikhethang e ntlafatsang ts'ebetso, boleng le ts'ebetso ea lihlahisoa tse fapaneng le libopeho. Polokeho ea eona, ho tšoarella, le ho baballa litšenyehelo li tlatsetsa bohlokoa ba eona mekhoeng ea morao-rao ea tlhahiso. Ha lipatlisiso le boqapi li ntse li tsoela pele ho holisa kutloisiso ea li-derivatives tsa cellulose, lits'ebetso le bohlokoa ba carboxymethylcellulose li lebelletsoe ho hola le ho feta lilemong tse tlang.
