Carboxymethyl celluloseSodium Carboxymethyl cellulose), e bitsoang CMC, ke motsoako oa polymer oa holim'a colloid e sebetsang.Ke ntho e sa nkheng, e sa latsoeheng, e se nang chefo e tsoang ka har'a selulose e qhibilihang ka metsing.organic cellulose binder ke mofuta oa cellulose ether, 'me letsoai la sodium le sebelisoa hangata, kahoo lebitso la lona le felletseng e lokela ho ba sodium carboxymethyl cellulose, ke hore, CMC-Na.
Joalo ka methyl cellulose, carboxymethyl cellulose e ka sebelisoa joalo ka sehlahiswa bakeng sa lisebelisoa tse refractory le joalo ka setlamo sa nakoana sa lisebelisoa tse refractory.
Sodium carboxymethyl cellulose ke polyelectrolyte ea maiketsetso, kahoo e ka sebelisoa e le dispersant le stabilizer bakeng sa seretse se refractory le li-castable, hape ke setlamo sa nakoana se sebetsang hantle haholo.E na le melemo e latelang:
1. Carboxymethyl cellulose e ka ba e adsorbed hantle holim'a likaroloana, e kene hantle 'me e kopantsoe le likaroloana, e le hore ho ka hlahisoa likheo tse matla tsa ho hanyetsa;
2. Kaha carboxymethyl cellulose ke anionic polymer electrolyte, e ka fokotsa ho sebelisana pakeng tsa likaroloana ka mor'a hore e be adsorbed holim'a karoloana, 'me e sebetse e le colloid e senyang le e sireletsang, kahoo e ntlafatsa boima le matla a sehlahisoa le ho fokotsa afterburning Inhomogeneity ea. sebopeho sa mokhatlo;
3. Ho sebelisa carboxymethyl cellulose e le binder, ha ho na molora ka mor'a ho chesa, 'me ho na le lisebelisoa tse fokolang tse fokolang haholo, tse ke keng tsa ama mocheso oa tšebeletso oa sehlahisoa.
Likarolo tsa Sehlahisoa
1. CMC e tšoeu kapa e mosehla fibrous granular phofo, tasteless, odorless, non-chefo, ha bonolo qhibilihang ka metsing, 'me e etsa pepenene viscous colloid,' me tharollo ke ho se nke lehlakore kapa hanyenyane alkaline.E ka bolokoa nako e telele ntle le ho senyeha, hape e tsitsitse tlas'a mocheso o tlase le khanya ea letsatsi.Leha ho le joalo, ka lebaka la phetoho e potlakileng ea mocheso, acidity le alkalinity ea tharollo e tla fetoha.Tlas'a tšusumetso ea mahlaseli a ultraviolet le likokoana-hloko, e tla boela e bake hydrolysis kapa oxidation, viscosity ea tharollo e tla fokotseha, esita le tharollo e tla senyeha.Haeba tharollo e hloka ho bolokoa nako e telele, ho ka khethoa li-preservative tse loketseng, tse kang formaldehyde, phenol, benzoic acid, le metsoako ea organic mercury.
2. CMC e tšoana le li-electrolyte tse ling tsa polymer.Ha e qhibiliha, e tla qala ho ruruha, 'me likaroloana li tla khomarela ho theha sehlopha sa filimi kapa viscose, e le hore li se ke tsa qhalakanngoa, empa ho qhibiliha ho lieha.Ka hona, ha u lokisetsa tharollo ea eona ea metsi, haeba likaroloana li ka kolobisoa ka mokhoa o ts'oanang pele, tekanyo ea ho qhibiliha e ka eketseha haholo.
3. CMC ke hygroscopic.Mongobo o tloaelehileng oa CMC sepakapakeng o eketseha ka ho eketseha ha mocheso oa moea mme o fokotseha ka ho eketseha ha mocheso oa moea.Ha mocheso o tloaelehileng oa mocheso oa kamore o le 80% -50%, mongobo o lekanang o ka holimo ho 26%, 'me mongobo oa sehlahisoa o ka tlase ho 10%.Ka hona, liphutheloana tsa lihlahisoa le polokelo li lokela ho ela hloko bopaki ba mongobo.
4. Matsoai a tšepe a boima a kang zinki, koporo, lead, aluminium, silevera, tšepe, thini, chromium, joalo-joalo, a ka baka pula ka tharollo ea metsi a CMC, 'me pula e ntse e ka qhibiliha hape ka sodium hydroxide kapa ammonium hydroxide solution. ntle le acetate ea motheo ea lead.
5. Organic kapa inorganic acids le tsona li tla baka pula ka tharollo ea sehlahisoa sena.Boemo ba pula bo fapane ka lebaka la mofuta le mahloriso a asiti.Ka kakaretso, pula e hlaha ka tlase ho pH 2.5, 'me e ka khutlisoa kamora ho se nke lehlakore ka ho eketsa alkali.
6. Matsoai a kang k'halsiamo, magnesium le letsoai la tafole ha a na phello ea pula holim'a tharollo ea CMC, empa a ama ho fokotseha ha viscosity.
7. CMC e lumellana le li-glues tse ling tse qhibilihang ka metsing, li-softeners le li-resin.
8. Filimi e huloang ke CMC e qoelisoa ka har'a acetone, benzene, butyl acetate, carbon tetrachloride, oli ea castor, oli ea poone, ethanol, ether, dichloroethane, petroleum, methanol, methyl acetate, methyl ethyl ether mocheso oa kamore Ketone, toluene, turpentine. , xylene, oli ea peanut, joalo-joalo li ka 'na tsa se ke tsa fetoha nakong ea lihora tse 24
