Ho fihlella botsitso ba Carboxymethyl Cellulose (CMC) glaze slurry ho bohlokoa bakeng sa ho netefatsa boleng bo tsitsitseng le ts'ebetso ea lihlahisoa tsa ceramic. Ho tsitsisa moelelong ona ho bolela ho boloka ho emisoa ha junifomo ntle le hore likaroloana li lule kapa li kopane ha nako e ntse e ea, e leng se ka lebisang ho sekoli sehlahisoa sa ho qetela.
Ho utloisisa CMC le Karolo ea eona ho Glaze Slurry
Carboxymethyl Cellulose (CMC) ke polima e qhibilihang ka metsing e nkiloeng ho selulose. E sebelisoa hangata ka likhalase tsa ceramic joalo ka setlamo le rheology modifier. CMC e ntlafatsa viscosity ea glaze, e thusa ho boloka ho emisoa ho tsitsitseng ha likaroloana. E boetse e ntlafatsa ho khomarela ha glaze holim'a ceramic le ho fokotsa likoli tse kang li-pinholes le ho khasa.
Lintlha tsa Bohlokoa tse Amang CMC Glaze Slurry Stability
Boleng le Boikutlo ba CMC:
Bohloeki: CMC ea bohloeki bo phahameng e lokela ho sebelisoa ho qoba litšila tse ka senyang botsitso.
Degree of Substitution (DS): DS ea CMC, e bonts'ang palo e tloaelehileng ea lihlopha tsa carboxymethyl tse khomaretsoeng mokokotlong oa cellulose, e ama ho qhibiliha ha eona le ts'ebetso ea eona. A DS pakeng tsa 0.7 le 1.2 hangata e loketse lits'ebetso tsa ceramic.
Boima ba Molek'hule: Boima ba limolek'hule bo phahameng ba CMC bo fana ka viscosity e ntle le thepa ea ho emisa, empa ho ka ba thata ho qhaqha. Ho leka-lekanya boima ba limolek'hule le boiketlo ba ho sebetsana le tsona ke habohlokoa.
Boleng ba Metsi:
pH: pH ea metsi a sebelisoang ho lokisa slurry e lokela ho se nke lehlakore ho ea ho alkaline hanyenyane (pH 7-8). Metsi a nang le asiti kapa a alkaline haholo a ka ama botsitso le ts'ebetso ea CMC.
Likahare tsa Ionic: Maemo a phahameng a letsoai le li-ion tse qhibilihisitsoeng a ka sebelisana le CMC mme a ama thepa ea eona e teteaneng. Hangata ho khothaletsoa ho sebelisa metsi a hloekisitsoeng kapa a nolofalitsoeng.
Mokhoa oa ho itokisa:
Ho qhibiliha: CMC e lokela ho qhibiliha hantle metsing pele e eketsa likarolo tse ling. Ho eketsa butle ka ho sisinyeha ka matla ho ka thibela ho hlaha ha leqeba.
Ho kopanya Taelo: Ho eketsa tharollo ea CMC ho lisebelisoa tsa glaze tse kopantsoeng pele kapa ka tsela e fapaneng ho ka ama homogeneity le botsitso. Ka tloaelo, ho qhaqha CMC pele ebe o eketsa lisebelisoa tsa glaze ho hlahisa litholoana tse ntle.
Botsofali: Ho lumella tharollo ea CMC hore e tsofale lihora tse 'maloa pele e sebelisoa ho ka ntlafatsa ts'ebetso ea eona ka ho netefatsa hore metsi a phalla ka ho feletseng le ho qhibiliha.
Li-additives le litšebelisano tsa tsona:
Li-deflocculants: Ho eketsa li-deflocculants tse nyane joalo ka sodium silicate kapa sodium carbonate ho ka thusa ho hasanya likaroloana ka ho lekana. Leha ho le joalo, tšebeliso e feteletseng e ka lebisa ho deflocculation e feteletseng le ho senya slurry.
Li-Preservatives: Ho thibela kholo ea likokoana-hloko, e ka theolang CMC, li-preservatives tse kang biocides li ka 'na tsa hlokahala, haholo-holo haeba slurry e bolokoa nako e telele.
Li-polymers tse ling: Ka linako tse ling, li-polymers tse ling kapa li-thickeners li sebelisoa hammoho le CMC ho lokisa rheology le botsitso ba glaze slurry.
Mehato e sebetsang ea ho tsitsisa CMC Glaze Slurry
Ho ntlafatsa Boikemisetso ba CMC:
Etsa qeto ea hore na CMC e tla ba bokae bakeng sa tlhahiso ea hau e khethehileng ea glaze ka liteko. Maemo a tloaelehileng a tloha ho 0.2% ho isa ho 1.0% ka boima ba motsoako o omileng oa glaze.
Butle-butle fetola mahloriso a CMC 'me u shebe viscosity le thepa ea ho emisoa ho fumana tekanyo e nepahetseng.
Ho netefatsa Homogeneous Mixing:
Sebelisa li-mixers tsa ho kuta tse phahameng kapa liloala tsa bolo ho netefatsa ho tsoakoa ka botlalo ha CMC le likarolo tsa glaze.
Nako le nako hlahloba slurry bakeng sa ho ts'oana 'me u fetole mekhahlelo ea ho kopanya ha ho hlokahala.
Ho laola pH:
Kamehla hlokomela le ho lokisa pH ea slurry. Haeba pH e hoholeha sebakeng se lakatsehang, sebelisa li-buffers tse loketseng ho boloka botsitso.
Qoba ho kenya lisebelisuoa tse nang le asiti kapa tse nang le alkaline ka kotloloho ka har'a slurry ntle le ho buffer hantle.
Tlhokomelo le ho fetola Viscosity:
Sebelisa li-viscometers ho lekola viscosity ea slurry khafetsa. Boloka lethathamo la lipalo tsa viscosity ho tseba mekhoa le litaba tse ka bang teng tsa botsitso.
Haeba viscosity e fetoha ha nako e ntse e ea, fetola ka ho eketsa metsi a manyane kapa tharollo ea CMC ha ho hlokahala.
Polokelo le Ts'ebetso:
Boloka seretse ka lijaneng tse koahetsoeng, tse hloekileng ho thibela tšilafalo le mouoane.
Kamehla hlohlelletsa slurry e bolokiloeng ho boloka ho fanyeha. Sebelisa li-stickers tsa mochini ha ho hlokahala.
Qoba ho boloka nako e telele mochesong o phahameng kapa khanyeng ea letsatsi, e ka senyang CMC.
Ho Rarolla Mathata a Tloaelehileng
Ho lokisa:
Haeba likaroloana li lula kapele, hlahloba khatello ea CMC 'me u netefatse hore e na le metsi ka botlalo.
Nahana ka ho eketsa palo e nyane ea deflocculant ho ntlafatsa ho emisoa ha likaroloana.
Gelation:
Haeba li-gels tsa slurry, li ka bontša ho phalla ho feteletseng kapa CMC e feteletseng. Fetola mohopolo 'me u hlahlobe litaba tsa ionic tsa metsi.
Netefatsa tatellano e nepahetseng ea mekhoa ea ho eketsa le ho kopanya.
Ho tsubella
Foam e ka ba bothata nakong ea ho kopanya. Sebelisa li-antifoaming agents ka mokhoa o fokolang ho laola foam ntle le ho ama thepa ea glaze.
Keketseho ea Likokoana-hloko:
Haeba slurry e hlahisa monko kapa liphetoho tse tsitsitseng, e ka 'na ea e-ba ka lebaka la ts'ebetso ea likokoana-hloko. Kenya biocides 'me u netefatse hore lijana le lisebelisoa li hloekile.
Ho fihlela botsitso ba CMC glaze slurry ho kenyelletsa motsoako oa ho khetha thepa e nepahetseng, ho laola mokhoa oa ho lokisa, le ho boloka mekhoa e nepahetseng ea ho boloka le ho sebetsana. Ka ho utloisisa karolo ea karolo e 'ngoe le e' ngoe le ho lekola liparamente tsa bohlokoa joalo ka pH, viscosity, le particle suspension, o ka hlahisa slurry e tsitsitseng le ea boleng bo holimo. Ho rarolla mathata kamehla le liphetoho tse thehiloeng ts'ebetsong e hlokometsoeng ho tla thusa ho boloka botsitso le boleng ba lihlahisoa tsa ceramic.
