Indastering ea letsopa,selulose ea carboxymethyl (CMC), motsoako oa polymer o qhibilihang ka metsing o tsoang ho cellulose ea tlhaho. CMC e fetohile tlatsetso ea bohlokoa ts'ebetsong ea tlhahiso ea 'mele e tala ea ceramic le li-glaze ka lebaka la ho teteana ha eona, ho kopana, ho boloka metsi, ho emisoa le thepa ea ho lokisa rheological. E ntlafatsa boleng ba bokaholimo le matla a mechini a lihlahisoa tsa ceramic ka ho ntlafatsa litšobotsi tsa rheological tsa slurry ea ceramic le thepa ea ho theha 'mele o motala, 'me e na le boleng bo boholo ba moruo le ba tekheniki.
1. Thepa ea motheo ea CMC
Carboxymethyl cellulose ke polymer e qhibilihang metsing e entsoeng ka ho hlahisa lihlopha tsa carboxymethyl (–CH₂–COOH) ho cellulose ea tlhaho ka karabelo ea etherification. Litšobotsi tsa eona tse ka sehloohong li kenyelletsa:
Ho qhibiliha hantle: E ka qhibiliha kapele metsing a batang le a chesang ho etsa tharollo e bonaletsang ea colloidal e nang le viscosity e phahameng.
Ho tenya le ho lokisa rheological: Tharollo ea CMC e na le viscosity e kholo 'me e ka fetola thixotropy ea ceramic slurry le glaze, e le hore e boloke botsitso bo itseng ha e eme 'me e eketsa phallo ea metsi ha ho sebelisoa matla a hlohlelletsoang kapa a ho beola.
Ho boloka metsi le botsitso: CMC e ka fokotsa ho feto-fetoha ha metsi ka katleho seretseng le glaze, ea ntlafatsa botsitso, 'me ea qoba ho aroloa kapa ho senngoa ha mobu.
Polokeho le tshireletso ya tikoloho: E tswa ho cellulose ya tlhaho, e bola ebile e bolokehile ho e sebedisa.
2. Karolo e ka sehloohong ea CMC tlhahisong ea letsopa
2.1. E le sesebelisoa sa ho qhala le ho tebisa seretse
Ha ho lokisetsoa mebele e tala ea letsopa, CMC e ka ntlafatsa haholo ho phalla le ho emisoa ha seretse. Ka ho eketsa viscosity le thixotropy ea seretse, CMC e thusa ho hasanya likaroloana tsa letsopa ka ho lekana, ho qoba pula, le ho nolofatsa ho lahla, ho fafatsa granulation kapa ho thellisa ente, ka hona ho ntlafatsa bongata le ho tšoana ha 'mele o motala.
2.2. E le thuso ea ho bopa le ho kopanya
Nakong ea ts'ebetso ea ho bōpa ka ho hatella kapa ho ntša, CMC e ka ntlafatsa plasticity le matla a ho bōpa 'mele o motala, e leng se etsang hore ho be bonolo ho o etsa 'me ho se ke ha e-ba bonolo ho petsoha. Litšobotsi tsa eona tse ntle tsa ho bōpa li ka boela tsa tlama likaroloana tsa ceramic ka thata nakong ea ts'ebetso ea ho omisa, tsa ntlafatsa matla a omileng a 'mele o motala, le ho fokotsa tahlehelo nakong ea ts'ebetso ea ho bōpa.
2.3. Ntlafatsa tshebetso ya ho betla
Ha ho lokisetsoa glaze, CMC e ka ntlafatsa haholo botsitso ba ho emisoa le ho phalla ha glaze slurry, ea thibela ho senngoa ha seretse le ho kopana ha lintho. Ho phaella moo, CMC e lokisa thixotropy ea glaze slurry, e etsa hore ts'ebetso ea glazing e tšoane haholoanyane, e fokotsa ho thella, 'me e ntlafatsa qetello ea bokaholimo ba lera la glaze.
2.4. Ho boloka metsi le ho hanyetsa mapetso
CMC e ka notlela mongobo ka katleho ka har'a seretse le glaze, ea fokotsa sekhahla sa ho oma, 'me ea fokotsa kotsi ea ho petsoha le ho sotha holim'a 'mele. Sena se bohlokoa haholo bakeng sa lihlahisoa tsa letsopa tse kholo kapa tse tšesaane, tse thusang ho ntlafatsa sekhahla sa ho tšoaneleha ha sehlahisoa.
2.5. Ntlafatsa boleng ba bokaholimo ba sehlahisoa
Ka ho ntlafatsa kabo ea likaroloana tsa 'mele le ho tšoana ha glazing, CMC e etsa hore bokaholimo ba lihlahisoa tsa letsopa tse besitsoeng bo be boreledi le bo bonolo haholoanyane, ha ka nako e ts'oanang e fokotsa ho hlaha ha liphoso tse kang masoba a pinhole le lipululana.
3. Tšebeliso ea CMC lits'ebetsong tse fapaneng tsa letsopa
Liserami tsa letsatsi le letsatsi: li ntlafatsa ho phalla ha lerōle le matla a 'mele, le ho fokotsa ho fetoha le ho petsoha ha lerōle nakong ea ho omisa le ho besa.
Ho haha li-ceramic (lithaele tsa ceramic, lithaele tsa lebota, lithaele tsa fatše): Ho ntlafatsa ho tšoana ha glazing le boleng ba glaze, le ho eketsa sekhahla sa chai.
Diserami tse ikgethang: Tlhahisong ya diserami tsa theknoloji e hodimo tse kang diserami tsa elektroniki le diserami tse sebetsang, CMC e sebediswa ho laola kabo ya dikarolwana le ho ntlafatsa matla a botala.
Khatiso ea 3D ea Ceramic: E le molaoli oa rheological le binder, e thusa ho fumana viscosity e loketseng ea slurry le ho nepahala ha khatiso.
4. Mabaka a amang phello ea CMC
Tekanyo ea phetolo (DS): Tekanyo ea phetolo ea carboxymethyl ho limolek'hule tsa CMC hangata e pakeng tsa 0.6–1.2. Ha DS e le holimo, ho qhibiliha ha metsi le bokhoni ba ho teteana ba CMC bo ba betere.
Boima ba limolek'hule le ho teteana: Ho teteana ho hoholo ha CMC ho fana ka ts'ireletso e matla ea metsi le litlamorao tsa ho teteana, empa ho ka baka hore ho phalla ha seretse ho fokotsehe; sehlopha se loketseng se hloka ho khethoa ho latela litlhoko tsa ts'ebetso.
Palo ea tlatsetso: Palo ea tlatsetso ea CMC tlhahisong ea letsopa ka kakaretso ke 0.1–0.5% ea boima ba lerōle, e hlokang ho ntlafatsoa ka liteko.
Mokhoa oa ho qhibiliha le ho hasana: CMC e hloka ho qhibilihisoa ka botlalo ka ho hlohlelletsa ka ho kuta ho hoholo pele ho qoba ho kopana ho fihlela phello e ntle ka ho fetisisa.
5. Melemo ea tikoloho le moruo
CMC e nkiloe ho cellulose ea tlhaho, e na le ho bola ha lintho tse phelang hantle le polokeho e ntle, 'me e fihlela litlhoko tse tala tsa tšireletso ea tikoloho ea indasteri ea sejoale-joale ea letsopa. Ho phaella moo, phello e phahameng ea tlatsetso ea CMC e ka fokotsa tšebeliso ea matla, ea khutsufatsa nako ea ho omisa le ho fokotsa sekhahla sa lithōle, ka hona ea ntlafatsa katleho ea tlhahiso le melemo ea moruo.
Indastering ea letsopa,CMC (carboxymethyl cellulose) ke sesebelisoa sa bohlokoa sa ho eketsa ts'ebetso. E thusa lihlahisoa tsa letsopa ho fihlella boleng bo holimo le katleho e phahameng ea tlhahiso ka ho ntlafatsa thepa ea rheological ea seretse le glaze, ho ntlafatsa matla a ho kopanya le matla a omileng a 'mele, le ho ntlafatsa phello ea glaze. Ka ho phehella ha indasteri ea letsopa tšireletso e tala ea tikoloho le tlhahiso e sebetsang hantle, litebello tsa ts'ebeliso ea CMC li tla ba ngata.
