Ceramic grade CMC

Ceramic grade CMC Sodium carboxymethyl cellulose tharollo e ka qhibiliha ka likhomaretsi tse ling tse qhibilihang ka metsing. Viscosity ea tharollo ea CMC e fokotseha ka ho eketseha ha mocheso, 'me viscosity e tla hlaphoheloa ka mor'a ho pholile. Tharollo ea metsi a CMC ke mokelikeli o seng oa Newtonian o nang le pseudoplasticity, 'me viscosity ea eona e fokotseha ka ho eketseha ha matla a tangential, ke hore, ho phalla ha tharollo ho ba betere ka ho eketseha ha matla a tangential. Tharollo ea sodium carboxymethyl cellulose (CMC) e na le sebopeho se ikhethileng sa marang-rang, se ka ts'ehetsa lintho tse ling hantle, e le hore sistimi eohle e qhalane ka ho lekana ka kakaretso.
Ceramic grade CMC e ka sebelisoa 'meleng oa ceramic, makhasi a benyang le mabenyane a majabajaba. E sebelisoa 'meleng oa ceramic, ke ntho e ntle e matlafatsang, e ka matlafatsang moldability ea seretse le lisebelisoa tsa lehlabathe, ho nolofatsa sebōpeho sa' mele le ho eketsa matla a ho phutha 'mele o motala.

Lisebelisoa:
1. Kopo ka glaze ea khatiso ea ceramic
CMC e na le solubility e ntle, ponaletso e phahameng ea tharollo 'me e batla e se na lisebelisoa tse sa lumellaneng. E na le pholiso e ntle ea ho kuta le lubricity, e ka ntlafatsang haholo ho ikamahanya le maemo ha khatiso le phello ea kamora ts'ebetso ea glaze ea khatiso. Ho sa le joalo, CMC e na le phello e ntle ea ho tiea, ho hasana le botsitso ha e sebelisoa ho glaze ea khatiso ea ceramic:
* Rheology e ntle ea khatiso ho netefatsa khatiso e boreleli;
* Paterone e hatisitsoeng e hlakile ’me ’mala oa lumellana;
* Boreleli bo phahameng ba tharollo, lubricity e ntle, ts'ebeliso e ntle ea ts'ebeliso;
* Ho qhibiliha ha metsi hantle, hoo e batlang e le lintho tsohle tse qhibilihisitsoeng, eseng letlooa le khomarelang, eseng letlooa le thibelang;
* Tharollo e na le ponaletso e phahameng le ho kenella hantle ha letlooa;
* Phallo e ntle ea shear, e ntlafatsa haholo mokhoa oa khatiso oa glaze ea khatiso;

2. Kopo ka glaze ea ho kenella ka ceramic
Embossing glaze e na le palo e kholo ea lintho tse qhibilihang ka letsoai, 'me acidic, embossing glaze CMC e na le ho hanyetsa acid e phahameng le botsitso ba ho hanyetsa letsoai, e le hore mahlaseli a ts'ebeliso ea ts'ebeliso le ho beoa a boloke viscosity e tsitsitseng, ho thibela phetoho ea viscosity le ho ama phapang ea mebala, ho ntlafatsa haholo botsitso ba embos:
* Sollubility e ntle, ha ho plug, ho kenella hantle;
* Ho lumellana hantle le glaze, e le hore palesa e khanye botsitso;
* Ho hanyetsa acid e ntle, khanyetso ea alkali, ho hanyetsa letsoai le botsitso, ho ka boloka viscosity ea glaze ea ho kenella e tsitsitse;
* Ts'ebetso ea boemo ba tharollo e ntle, 'me botsitso ba viscosity bo botle, bo ka thibela liphetoho tsa viscosity ho ama phapang ea mebala.

3. Kopo ka 'mele oa ceramic
CMC e na le sebopeho se ikhethileng sa polymer. Ha CMC e eketsoa metsing, sehlopha sa eona sa hydrophilic se kopantsoe le metsi ho etsa lera le qhibilihisitsoeng, e le hore limolek'hule tsa CMC li qhalane butle-butle metsing. Li-polymers tsa CMC li itšetlehile ka hydrogen bond le van der Waals force ho theha sebopeho sa marang-rang, kahoo se bontša ho khomarela. CMC bakeng sa 'mele oa embryo oa ceramic e ka sebelisoa e le mothusi, polasetiki le moemeli ea matlafatsang' mele oa embryo indastering ea ceramic.
* Tekanyetso e fokolang, matla a ho kobeha a tala a eketsa katleho e hlakile;
* Ntlafatsa lebelo la ts'ebetso e tala, fokotsa tšebeliso ea matla a tlhahiso;
* Tahlehelo e ntle ea mollo, ha ho na masala ka mor'a ho chesa, ha e ame 'mala o motala;
* Ho bonolo ho sebetsa, ho thibela ho putlama ha glaze, ho haella ha glaze le liphoso tse ling;
* Ka phello e khahlanong le coagulation, e ka ntlafatsa metsi a peista ea glaze, e bonolo ho fafatsa ts'ebetso ea glaze;
* Joaloka motsoako oa billet, eketsa polasetiki ea lehlabathe, ho bonolo ho theha 'mele;
* Matla a matla a ho roala ha mochini, tšenyo e fokolang ea limolek'hule nakong ea ho sila le ho sisinyeha ha mochini;
* Joaloka moemeli ea matlafatsang billet, eketsa matla a ho kobeha ha billet e tala, ntlafatsa botsitso ba billet, fokotsa sekhahla sa tšenyo;
* Ho emisoa ho matla le ho hasana, ho ka thibela lisebelisoa tse tala tse futsanehileng le likaroloana tsa pulp ho lula, e le hore slurry e qhalane ka tsela e tšoanang;
* Etsa hore mongobo o ka har'a billet o fetohe mouoane ka mokhoa o ts'oanang, thibela ho omisa le ho phunyeha, haholo-holo ho sebelisoa ka boholo bo boholo ba li-tile tsa fatše le li-billet tsa litene tse betliloeng, phello e totobetse.

4. Kopo ka ceramic glaze slurry
CMC ke ea sehlopha sa polyelectrolyte, e sebelisoang haholo e le setlamo le ho emisoa ho glaze slurry. Ha CMC ka glaze slurry, metsi seep ka CMC polasetiki sengoathoana ka hare, hydrophilic sehlopha ho kopantswe le metsi, hlahisa metsi absorption katoloso, ha micelle ka hydration katoloso, ka ntle ka hare ho kopantswe le lera la metsi ho thehoa, micelle mathoasong a qhibiliha mohato ka tharollo sekgomaretsi, ka lebaka la boholo, sebopeho asymmetry, ka lebaka la boholo, sebopeho asymmetry, metsi, butle-butle theha asymmetry, 'me butle-butle e thehile marang-rang. bokhoni bo matla ba ho khomarela:
* Tlas'a boemo ba tekanyo e tlaase, ka katleho fetola rheology ea glaze peista, ho bonolo ho sebelisa glaze;
* Ntlafatsa ts'ebetso ea maqhama a glaze e se nang letho, ntlafatsa matla a glaze haholo, thibela ho putlama;
* Bokhabane bo phahameng ba glaze, pente e tsitsitseng ea glaze, 'me e ka fokotsa lesoba la glaze e sintered;
* Ts'ebetso e ntle ea ho hasana le ts'ireletso ea colloid, e ka etsa hore glaze e be maemong a tsitsitseng a qhalakantsoeng;
* Ntlafatsa ka katleho tsitsipano ea holim'a glaze, thibela metsi ho tsoa ho glaze ho ea 'meleng, eketsa boreleli ba glaze;
* Qoba ho phatloha le ho hatisa ho robeha nakong ea ho tsamaisa ka lebaka la ho theoha ha matla a 'mele ka mor'a ho qhoqhoa.
