Carboxymethyl cellulose (CMC) ke polymer e phahameng ea molek'hule e sebelisoang haholo marong a ho cheka a nang le thepa e ntle ea rheological le botsitso. Ke selulose e fetotsoeng, haholo-holo e entsoeng ka ho arabela selulose ka chloroacetic acid. Ka lebaka la ts'ebetso ea eona e ntle haholo, CMC e sebelisitsoe haholo mafapheng a mangata a kang ho cheka oli, merafo, kaho le indasteri ea lijo.
1. Thepa ea CMC
Carboxymethyl cellulose ke phofo e tšoeu ho isa ho e mosehla e bobebe e etsang tharollo e hlakileng ea colloidal ha e qhibiliha ka metsing. Sebopeho sa eona sa lik'hemik'hale se na le lihlopha tsa carboxymethyl, tse etsang hore e be le hydrophilicity e ntle le lubricity. Ntle le moo, viscosity ea CMC e ka laoloa ka ho fetola boima ba eona ba limolek'hule le mahloriso, e leng se etsang hore ts'ebeliso ea eona ho maro a ho cheka a fetohe haholo.
2. Karolo ea ho cheka maro
Nakong ea ts'ebetso ea ho cheka, ts'ebetso ea maro a ho cheka a bohlokoa. CMC e bapala karolo e latelang ea mantlha ho maro a ho cheka:
Thickener: CMC e ka eketsa viscosity ea maro a ho cheka, ka tsela eo ea ntlafatsa bokhoni ba bona ba ho jara, ho boloka likaroloana tse tiileng tse emisitsoeng, le ho thibela ho thella.
Rheology modifier: Ka ho lokisa thepa ea rheological ea mokelikeli oa ho cheka, CMC e ka ntlafatsa metsi a eona e le hore e ntse e ka boloka metsi a matle tlas'a mocheso o phahameng le maemo a khatello e phahameng.
Sesebelisoa sa plug: Likaroloana tsa CMC li ka tlatsa mapetsong a majoe, tsa fokotsa tahlehelo ea mokelikeli ka nepo le ho ntlafatsa ts'ebetso ea ho cheka.
Lubricant: Ho eketsoa ha CMC ho ka fokotsa khohlano lipakeng tsa sekoaelo le lebota la seliba, ho fokotsa ho khathala le ho eketsa lebelo la ho phunya.
3. Melemo ea CMC
Ho sebelisa carboxymethyl cellulose joalo ka motsoako oa mokelikeli oa ho cheka ho na le melemo e latelang:
E na le botsoalle ho tikoloho: CMC ke thepa ea tlhaho ea polymer e nang le biodegradability e ntle le tšusumetso e nyane tikolohong.
Tšebeliso e ntle ea litšenyehelo: Ha e bapisoa le li-polymer tse ling tsa maiketsetso, CMC e na le litšenyehelo tse tlase, ts'ebetso e ntle haholo le litšenyehelo tse phahameng.
Boemo ba mocheso le letsoai: CMC e ntse e ka boloka ts'ebetso e tsitsitseng mochesong o phahameng le tikolohong ea letsoai le phahameng le ho ikamahanya le maemo a fapaneng a jeoloji.
4. Mehlala ea tšebeliso
Likopong tsa 'nete, lik'hamphani tse ngata tsa oli li sebelisitse CMC ka katleho mererong e fapaneng ea ho cheka. Ka mohlala, libakeng tse ling tsa mocheso o phahameng le liliba tsa khatello e phahameng, ho eketsa palo e loketseng ea CMC ho ka laola ka katleho rheology ea seretse le ho etsa bonnete ba ho cheka ho boreleli. Ho feta moo, ka mekhoa e meng e rarahaneng, ho sebelisa CMC e le sesebelisoa sa ho phunya ho ka fokotsa haholo tahlehelo ea mokelikeli le ho ntlafatsa bokhoni ba ho cheka.
5. Litlhokomelo
Leha CMC e na le melemo e mengata, lintlha tse latelang li lokela ho hlokomeloa nakong ea ts'ebeliso:
Tekanyo: Fetola palo ea CMC e ekelitsoeng ho latela maemo a nnete. Tšebeliso e feteletseng e ka lebisa ho fokotseha ha metsi.
Maemo a polokelo: E lokela ho bolokoa sebakeng se omeletseng le se phodileng ho qoba mongobo o amang ts'ebetso.
Ho kopanya ka ho lekana: Ha o lokisa mokelikeli oa ho cheka, etsa bonnete ba hore CMC e qhibilihile ka botlalo ho qoba ho kopana ha likaroloana.
Tšebeliso ea carboxymethyl cellulose mokelikeli oa ho cheka ha e ntlafatse bokhoni ba ho cheka feela le ho fokotsa litšenyehelo, empa hape e khothalletsa nts'etsopele ea theknoloji ea tšireletso ea tikoloho ho isa bohōleng bo itseng. Ka tsoelopele ea mahlale le thekenoloji, sebaka sa ts'ebeliso ea CMC se tla atolosoa le ho feta, 'me re lebelletse ho bapala karolo e kholo mererong ea kamoso ea ho cheka.
