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 glaze e khabisitsoeng ka mokhoa oa ho sebelisoa le ho behoa ho boloka viscosity e tsitsitseng, ho thibela phetoho ea viscosity le ho ama. phapang ea 'mala, e ntlafatsa haholo botsitso ba glaze ea embossing:
* 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 'meleng 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 a kena ka har'a sekhechana sa polasetiki sa CMC ka hare, sehlopha sa hydrophilic se kopantsoeng le metsi, se hlahisa katoloso ea metsi, ha micelle e le katoloso ea hydration, ka ntle ho ka hare ho kopantsoe le lera la metsi ho thehoa, micelle karolong e qalang ea ho qhibiliha. tharollo ea sekhomaretsi, ka lebaka la boholo, sebopeho sa asymmetry, 'me se kopantsoe le metsi butle-butle se thehile sebopeho sa marang-rang, molumo o moholo haholo, ka hona, o na le matla a 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.

Sephutheloana:
Sehlahisoa sa CMC se pakiloe ka mokotleng oa pampiri oa mekhahlelo e meraro e nang le mokotla o ka hare oa polyethylene o matlafalitsoeng, boima ba letlooa ke 25kg mokotla ka mong.
