Li-cellulose ethers ke sehlopha sa bohlokoa sa lihlahisoa tsa tlhaho tsa polymer, tse sebelisoang haholo libakeng tse ngata tsa indasteri le tsa bophelo. Li-cellulose ethers ke lihlahisoa tse fetotsoeng tsa selulose tse entsoeng ka ho kopanya selulose ea tlhaho le metsoako ea ether ka liphetoho tsa lik'hemik'hale. Ho latela li-substitute tse fapaneng, li-cellulose ethers li ka aroloa ka methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose (CMC) le mefuta e meng. Lihlahisoa tsena li na le li-thickening tse ntle, li tlamahano, ho etsa lifilimi, ho boloka metsi, ho tlotsa le lintho tse ling, kahoo li sebelisoa haholo kahong, meriana, lijo, litlolo, ho ntša oli, ho etsa pampiri le liindasteri tse ling.
1. Indasteri ea kaho
Li-cellulose ethers li phetha karolo ea bohlokoa ho thepa ea mohaho, haholo-holo ka seretse se omeletseng, phofo ea putty, liaparo le li-adhesives tsa lithaele. Mesebetsi ea eona ea mantlha e kenyelletsa ho tenya, ho boloka metsi, ho tlotsa le ho ntlafatsa ts'ebetso ea kaho. Ka mohlala:
Matla a matla: Li-cellulose ethers li ka eketsa viscosity ea seretse le liphahlo, tsa etsa hore li be betere kahong le ho qoba ho theoha.
Ho boloka metsi: Sebakeng se omeletseng, cellulose ether e ka boloka mongobo ka nepo, ea thibela metsi hore a se ke a fetoha mouoane ka potlako, e etsa bonnete ba hore ho na le hydration e felletseng ea lisebelisoa tsa samente tse kang samente kapa gypsum, le ho ntlafatsa matla a tlamahano le ts'ebetso ea thepa.
Ntlafatsa ts'ebetso ea kaho: Cellulose ether e ka ntlafatsa mafura a thepa ea moaho, ea etsa hore e be boreleli nakong ea kaho, ho be bonolo ho e sebelisa kapa ho beha, le ho ntlafatsa ts'ebetso ea kaho le boleng ba bokaholimo.
2. Indasteri ea meriana
Lefapheng la meriana, cellulose ether e sebelisoa haholo ho lokiseng lithethefatsi, ho roala letlapa, le bajari ba lithethefatsi tse sa khaotseng. Lisebelisoa tse tloaelehileng li kenyelletsa:
Ho bōptjoa ha Letlapa: Cellulose ether, e le setlamo le ho senya matlapa, e ka khothalletsa ka katleho ho thehoa ha matlapa 'me ea senyeha ka potlako ha e nkoa ho netefatsa ho kenngoa ha lithethefatsi.
Sistimi e laoloang ea tokollo: Li-ether tse ling tsa cellulose li na le thepa e ntle ea ho etsa lifilimi le thepa ea ho senyeha e laolehang, kahoo hangata li sebelisoa ho lokiseng lithethefatsi tse lokolotsoeng, tse ka laolang sekhahla sa ho lokolloa ha lithethefatsi 'meleng oa motho le ho lelefatsa katleho ea lithethefatsi. .
Ho roala ka capsule: Thepa e etsang filimi ea cellulose ether e etsa hore e be thepa e loketseng ea ho roala lithethefatsi, e ka arolang lithethefatsi ho tloha tikolohong e ka ntle, ho qoba ho oxidation le hydrolysis ea lithethefatsi, le ho eketsa botsitso ba lithethefatsi.
3. Indasteri ea lijo
Lefapheng la lijo, li-cellulose ethers li sebelisoa haholo e le li-additives, haholo-holo lihlahisoa tse halikiloeng, lihlahisoa tsa lebese, lino tse tahang le lijo tse leqhoa. Mesebetsi ea eona ea mantlha e kenyelletsa:
Thickener: Li-cellulose ethers li ka eketsa viscosity ea lijo tse metsi, tsa ntlafatsa tatso, 'me tsa etsa hore lihlahisoa li be le sebopeho le tse teteaneng. Hangata li sebelisoa lijong tse kang li-sauces, jellies le litlolo.
Stabilizer: Li-cellulose ethers, e le li-emulsifiers le stabilizers, li ka thibela ka katleho ho arohana ha oli le metsi lijong le ho netefatsa ho lumellana le boleng ba lihlahisoa.
Humectant: Lijong tse phehiloeng, li-cellulose ethers li ka thusa hlama ho boloka mongobo, ho thibela tahlehelo ea metsi a mangata nakong ea ho baka, le ho netefatsa bonolo le tatso ea sehlahisoa se felileng.
4. Indasteri ea litlolo
Tšebeliso ea li-cellulose ethers indastering ea litlolo e bonahala haholo lihlahisoa tsa tlhokomelo ea letlalo, li-shampoo, lihloekisi tsa sefahleho le lihlahisoa tsa litlolo. Lits'oants'o tsa eona tse ntle haholo tsa moisturizing, thickening, film-forming and stabilizing li etsa hore e be motsoako oa bohlokoa mefuteng ea litlolo. Ka mohlala:
Moisturizer: Cellulose ethers e ka etsa filimi e sireletsang ho koala mongobo holim'a letlalo le ho thusa letlalo hore le lule le le mongobo.
Thickener: Joalo ka setenya, cellulose ether e fa lihlahisoa tsa litlolo mokhoa o loketseng, ho etsa hore ho be bonolo ho li sebelisa le ho monya, le ho ntlafatsa boiphihlelo ba mosebelisi.
Emulsifier: Cellulose ether e ka tsitsisa li-emulsion, ea thibela ho arohana ha metsi a oli, le ho boloka botsitso ba litlolo tsa litlolo.
5. Indasteri ea ho ntša oli
Tšebeliso ea cellulose ether ho ntšoa ha oli e bonahala haholo-holo ho lokisoeng ha maro a ho cheka le maro a fracturing. Cellulose ether e ka sebelisoa e le setenya, se fokotsang tahlehelo ea mokelikeli le stabilizer ho ntlafatsa ts'ebetso ea maro a ho cheka. Ka mohlala:
Thickener: Cellulose ether e ka eketsa viscosity ea maro a ho cheka, ea thusa ho emisa le ho jara likheo tsa ho phunya, le ho thibela ho putlama ha seliba.
Mokelikeli o fokotsang tahlehelo ea metsi: Ka tlas'a mocheso o phahameng le maemo a khatello e phahameng, cellulose ether e ka fokotsa tahlehelo ea mokelikeli oa maro a ho cheka, ho sireletsa likarolo tsa oli le mabota a seliba, le ho ntlafatsa bokhoni ba ho cheka.
6. Indasteri ea ho etsa lipampiri
Lefapheng la ho etsa pampiri, cellulose ether e sebelisoa e le ntho e matlafatsang, ho roala le ho etsa filimi bakeng sa pampiri. E ka ntlafatsa matla, botlolo le boreleli ba pampiri le ho ntlafatsa ho ikamahanya le maemo ho hatisa. Ka mohlala:
Reinforcer: Cellulose ether e ka ntlafatsa matla a tlamahano pakeng tsa likhoele tsa pulp, ho etsa hore pampiri e be thata le ho tšoarella ho feta.
Moemeli oa ho roala: Ts'ebetsong ea ho roala pampiri, cellulose ether e ka thusa ho roala ho lekana, ho ntlafatsa boreleli le ho ikamahanya le maemo ha pampiri.
Moemeli oa ho etsa lifilimi: Cellulose ether e etsa filimi e tšesaane holim'a pampiri, e eketsa ho hanyetsa mongobo le ho tšoarella ha pampiri.
7. Liindasteri tse ling
Cellulose ether e boetse e sebelisoa haholo liindastering tse ling, tse kang masela, letlalo, thepa ea elektronike, tšireletso ea tikoloho le masimo a mang. Indastering ea masela, cellulose ether e ka sebelisoa bakeng sa boholo ba likhoele, ho qeta lesela le ho hasana ha dae; ts'ebetsong ea letlalo, ether ea cellulose e ka sebelisoa e le motenya le moemeli oa ho roala; tšimong ea ts'ireletso ea tikoloho, cellulose ether e ka sebelisoa e le flocculant le adsorbent kalafo ea metsi bakeng sa ho hloekisa metsi a litšila.
E le sehlahisoa se fetotsoeng sa thepa ea tlhaho ea polymer, cellulose ether e phetha karolo ea bohlokoa likarolong tse ngata tse kang kaho, meriana, lijo, litlolo, ho ntša oli, ho etsa pampiri, joalo-joalo ka ho teteka ha eona ho babatsehang, ho boloka metsi, ho thehoa ha filimi, botsitso le thepa e 'ngoe. . Ka tsoelo-pele e tsoelang pele ea theknoloji, sebaka sa ts'ebeliso le ts'ebetso ea li-cellulose ethers li ntse li hola. Nakong e tlang, li-cellulose ethers li lebeletsoe hore li bontše bokhoni bo eketsehileng le boleng ba tšebeliso ea lisebelisoa tse tala le tse nang le tikoloho, litokisetso tse ncha tsa meriana le lisebelisoa tse bohlale.
