Tšebeliso ea carboxymethyl cellulose indastering ea ceramic

Carboxymethyl cellulose (CMC) ke motsoako oa bohlokoa oa polima oa tlhaho o 'nileng oa sebelisoa haholo indastering ea ceramic. Joalo ka sekhomaretsi se qhibilihang ka metsi, CMC e ka ntlafatsa ts'ebetso ea lisebelisoa tsa ceramic, ea khothaletsa botsitso le ho ts'oana nakong ea ts'ebetso, le ho ntlafatsa boleng ba sehlahisoa sa ho qetela.

1. Lintho tsa motheo tsa carboxymethyl cellulose

Carboxymethyl cellulose ke ntho e tsoang ho selulose, e nang le ho qhibiliha ha metsi hantle, ho khomarela le ho tiisa thepa ka ho fetola lik'hemik'hale. Sebopeho sa limolek'hule tsa CMC se na le lihlopha tsa carboxyl (-COOH), tse e nolofalletsang ho etsa tharollo ea colloidal ka metsing e nang le thepa e ntle ea ho khomarela le ea rheological. Lintho tsena li etsa hore CMC e be tlatsetso ea bohlokoa tlhahisong ea ceramic.

2. Kopo ka tlhahiso ea ceramic

2.1 Sekhomaretsi

Ts'ebetsong ea ho bōptjoa ha lihlahisoa tsa ceramic, CMC hangata e sebelisoa e le sekhomaretsi. E ka ntlafatsa ka katleho matla a tlamahano pakeng tsa likaroloana tse tala le ho thibela ho phunyeha le ho senyeha nakong ea ho omisa le ho sintering. Ka ho ntlafatsa palo ea CMC e ekelitsoeng, thepa ea rheological ea slurry e ka fetoloa ho e etsa hore e sebetse haholoanyane nakong ea ho bopa.

2.2 Thickener

CMC e na le thepa e matla ea ho tenya mme e ka sebelisoa ho lokisa viscosity ea slurry ea ceramic. Sena ke sa bohlokoa haholo bakeng sa lits'ebetso tse kang ho fafatsa le ho tšela, tse ka netefatsang botsitso ba slurry nakong ea ts'ebetso le ho qoba pula kapa stratification. Ka nako e ts'oanang, viscosity e loketseng e ka ntlafatsa ho phalla ha slurry, ho etsa hore ho be bonolo ho tlatsa hlobo.

2.3 Ea qhalaneng

Ka tlhahiso ea ceramic, CMC e ka boela ea sebelisoa e le dispersant ho thusa ho qhala likaroloana tse ka har'a thepa e tala ea ceramic le ho thibela agglomeration. Ts'ebetso e ntle ea ho hasana e thusa ho ntlafatsa ho tšoana le ho teteana ha lihlahisoa tsa ceramic, ka hona ho ntlafatsa thepa ea mochini le thepa ea optical ea sehlahisoa sa ho qetela.

3. Phello ea CMC ho Thepa ea Ceramic

Kamora ho eketsa CMC, ts'ebetso ea lihlahisoa tsa ceramic hangata e ntlafatsoa. Boithuto bo bonts'itse hore palo e nepahetseng ea CMC e ka ntlafatsa haholo matla a hatellang le matla a fetohang a lihlahisoa tsa ceramic. Ntle le moo, tlatsetso ea CMC e ka boela ea ntlafatsa boreleli ba bokaholimo le botlolo ba li-ceramics, ea etsa hore sehlahisoa sa ho qetela se be ntle le ho feta.

4. Botsoalle ba tikoloho ea CMC

Ha ho bapisoa le li-polymer tsa setso tsa maiketsetso, CMC, joalo ka polima ea tlhaho, e na le tšebelisano e ntle le tikoloho. Tšebeliso ea CMC ts'ebetsong ea tlhahiso ea ceramic e ke ke ea ntlafatsa ts'ebetso ea lihlahisoa feela, empa hape e fokotsa tšilafalo ea tikoloho le kotsi ho 'mele oa motho, o finyellang litlhoko tsa tsoelo-pele e tsitsitseng ea morao-rao.

Tšebeliso ea carboxymethyl cellulose indastering ea ceramic e bonts'a mesebetsi ea eona e mengata joalo ka setlamo, setenya le se qhalakanya. Ka ho ntlafatsa ts'ebeliso ea eona, ts'ebetso le boleng ba lihlahisoa tsa ceramic li ka ntlafatsoa haholo, ho khothaletsa nts'etsopele e tsitsitseng ea indasteri ea ceramic. Ka ho teba ha lipatlisiso le tsoelo-pele ea theknoloji, litebello tsa ts'ebeliso ea CMC tlhahiso ea ceramic li tla ba tse pharaletseng.
