Li-ether tsa cellulose ke li-polymer tse feto-fetohang le tse feto-fetohang tse nang le ts'ebeliso liindastering tse fapaneng, ho kenyeletsoa tlhahiso ea li-ceramic tsa mahe a linotši le lihlahisoa tse ling.
1. Selelekela ho ether ea selulose:
Li-ether tsa cellulose ke lintho tse tsoang ho cellulose, e leng polymer ea tlhaho e fumanoang maboteng a sele ea limela. E fumanoa ka phetoho ea lik'hemik'hale ea cellulose, e leng se fellang ka li-polymer tse qhibilihang ka metsing kapa tse qhalanang ka metsi. Mehloli e tloaelehileng ea cellulose e kenyelletsa pulp ea lehong, k'hothone le thepa e 'ngoe ea limela.
2. Mefuta ea li-ether tsa cellulose:
Ho na le mefuta e mengata ea li-ether tsa cellulose, e 'ngoe le e 'ngoe e na le thepa e ikhethang e loketseng lits'ebetso tse itseng. Mefuta e meng e tloaelehileng e kenyelletsa methylcellulose (MC), ethylcellulose (EC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), le carboxymethylcellulose (CMC). Khetho ea ether ea cellulose e itšetlehile ka thepa e lakatsehang ea sehlahisoa sa ho qetela.
3. Ts'ebetso ea tlhahiso:
Tlhahiso ea li-ether tsa cellulose e kenyelletsa mehato e 'maloa, ho kenyeletsoa ho ntšoa ha cellulose, phetoho ea lik'hemik'hale le tlhoekiso. Cellulose e ntšoa pele limela ebe ho sebelisoa liketso tsa lik'hemik'hale ho hlahisa lihlopha tse sebetsang tse kang methyl, ethyl, hydroxyethyl kapa carboxymethyl. Ether ea cellulose e hlahisoang e ntan'o hloekisoa ho tlosa litšila le ho fihlela boleng bo lakatsehang.
4. Litšobotsi tsa ether ea selulose:
Li-ether tsa cellulose li na le mefuta e fapaneng ea thepa e lakatsehang, e leng se etsang hore li lokele mefuta e mengata ea ts'ebeliso. Litšobotsi tsena li kenyelletsa ho qhibiliha ha metsi, bokhoni ba ho etsa filimi, bokhoni ba ho teteana, le botsitso mochesong o moholo le pH. Litšobotsi tsena li kenya letsoho ho feto-fetohang ha li-ether tsa cellulose liindastering tse fapaneng.
5. Tšebeliso ea ether ea selulose:
Li-ether tsa cellulose li sebelisoa liindastering tse ngata, ho kenyeletsoa meriana, lijo, kaho, masela le li-ceramic. Ts'ebeliso ea tsona e tloha tšebelisong e le moemeli oa ho teteana lijong ho isa ho ntlafatseng thepa ea thepa ea kaho. Lefapheng la li-ceramic, li-ether tsa cellulose li bapala karolo ea bohlokoa tlhahisong ea li-ceramic tsa mahe a linotši.
6. Ether ea cellulose ka har'a li-ceramic tsa mahe a linotši:
Liserame tsa mahe a linotši ke thepa ea sebopeho e nang le lisele tse hlophisitsoeng ka mokhoa oa hexagonal kapa oa mahe a linotši. Liserame tsena li tsebahala ka sebaka sa tsona se phahameng sa bokaholimo, katoloso e tlase ea mocheso, le thepa e ntle ea ho fetisa mocheso le boima. Li-ether tsa cellulose li sebelisoa ho hlahiseng liserame tsa mahe a linotši ka mabaka a latelang:
Li-binder le Li-Rheology Modifiers: Li-ether tsa cellulose li sebetsa e le li-binder, li tšoara likaroloana tsa ceramic hammoho nakong ea ts'ebetso ea ho bopa. Ho feta moo, e sebetsa e le modifier ea rheology, e amang phallo le phetoho ea li-slurry tsa ceramic.
Ho thehoa ha 'mele o motala: Li-slurry tsa ceramic tse nang le li-ether tsa cellulose li sebelisoa ho etsa 'mele o motala bakeng sa li-ceramic tsa mahe a linotši. 'Mele o motala ke meaho ea ceramic e sa besoang e bōpehileng le e omisitsoeng pele ho ts'ebetso e 'ngoe.
Ho kopanya le ho omisa: Li-ether tsa cellulose li thusa likaroloana tsa letsopa ho kopana nakong ea ts'ebetso ea ho omisa. E thibela ho petsoha le ho fetoha ha 'mele, e netefatsa hore 'mele o motala o boloka botsitso ba sebopeho sa oona.
Ho chesa le ho sila: Mehatong e latelang ea tlhahiso ea ceramic ea mahe a linotši, li-ether tsa cellulose lia cha, li siea likheo tse thusang ho theha sebopeho sa khekhe ea linotši. Ts'ebetso ea ho sila e tsoela pele ho fumana sehlahisoa sa ho qetela sa ceramic.
7. Ditshebediso tse ding tsa di-ether tsa selulose:
Ntle le li-ceramic tsa mahe a linotši, li-ether tsa cellulose li sebelisoa lihlahisoa le liindastering tse ling tse fapaneng:
Meriana: E sebelisoa e le ntho e kopanyang le e qhalang matlapeng.
Indasteri ea lijo: Li-ether tsa cellulose li sebelisoa e le li-thickeners, li-stabilizer le li-emulsifier lijong.
Thepa ea Kaho: E ntlafatsa litšobotsi tsa li-mortar, likhomaretsi le lipente.
Masela: Li-ether tsa cellulose li sebelisoa ho hatiseng le ho beheng boholo ba masela.
8. Liphephetso le lintho tse lokelang ho nahanoa:
Leha di-ether tsa cellulose di fana ka melemo e mengata, tshebediso ya tsona e boetse e hlahisa diphephetso tse ding. Tsena di ka kenyeletsa mathata a tikoloho a ka bang teng a amanang le tshebetso ya tlhahiso le tlhoko ya ho fumana thepa e tala ka tsela e tsitsitseng. Mosebetsi wa dipatlisiso le ntshetsopele o ntse o tswela pele ho rarolla diphephetso tsena le ho ntlafatsa botsitso ka kakaretso ba dihlahiswa tsa ether tsa cellulose.
9. Mekhoa le tsoelo-pele ea nakong e tlang:
Ha theknoloji e ntse e tswela pele le botsitso e ntse e fetoha taba ya bohlokwa le ho feta, bokamoso ba di-ether tsa cellulose bo ka kenyeletsa boqapi ditsamaisong tsa tlhahiso, tshebediso e eketsehileng ya thepa e tala e thehilweng hodima bio, le ntshetsopele ya ditshebediso tse ntjha. Ho fetofetoha ha di-ether tsa cellulose ho etsa hore e be thepa e tshepisang bakeng sa diindasteri tse fapaneng, mme dipatlisiso tse tswelang pele di ka senola menyetla e metjha.
10. Qetello:
Li-ether tsa cellulose ke li-polymer tse feto-fetohang tse nang le lits'ebetso tse ngata liindastering tse ngata. Tšebeliso ea eona ka har'a li-ceramic tsa sele e totobatsa bohlokoa ba eona ho bopeng thepa e tsoetseng pele e nang le thepa e ikhethang. Ha liindasteri li ntse li tsoela pele ho batla thepa e tsitsitseng le e sebetsang, li-ether tsa cellulose li lebelletsoe ho bapala karolo ea bohlokoa ho fihlelleng litlhoko tsena. Lipatlisiso le nts'etsopele e tsoelang pele li tla atolosa ts'ebeliso ea lihlahisoa tsa ether tsa cellulose le ho ntlafatsa botsitso ba tsona ka kakaretso.
