Li-ether tsa cellulose ke li-thickeners tse sebelisoang haholo indastering ea ho roala ka metsi. Li entsoe ka cellulose, e leng polymer ea tlhaho e fumanoang maboteng a sele ea limela. Li-ether tsa cellulose li sebelisoa ho ntlafatsa litšobotsi tsa ho roala ka metsi, e leng se etsang hore ho be bonolo ho li sebelisa le ho li tšoarella haholoanyane.
Lipente tse thehiloeng metsing li ntse li tuma haholo indastering ea lipente ka lebaka la botsoalle ba tsona tikolohong le ts'ebetso e ntle haholo. Li bonolo ho li sebelisa, li omella kapele 'me lia tšoarella. Leha ho le joalo, melemo ena e tla ka theko e tlase. Pente tse thehiloeng metsing hangata li tšesaane ho feta pente tse thehiloeng ho solvent 'me li hloka li-thickeners ho li etsa hore li be viscous haholoanyane. Mona ke moo li-ether tsa cellulose li kenang teng.
Cellulose ether ke polymer e qhibilihang ka metsing e nkiloeng ho cellulose. E hlahisoa ka ho kopanya cellulose le lik'hemik'hale tse fapaneng tse kang alkalis kapa li-etherifying agents. Sephetho ke sehlahisoa se nang le bokhoni bo botle ba ho qhibiliha ha metsi le ho teteana. Cellulose ethers e sebelisoa haholo e le li-thickeners liphahlong tse thehiloeng metsing ka lebaka la melemo ea tsona e mengata.
E 'ngoe ea melemo e meholo ea ho sebelisa li-ether tsa cellulose e le sethibisi ke bokhoni ba eona ba ho fana ka taolo e ntle ea viscosity. Ho fapana le li-thickeners tse ling, li-ether tsa cellulose ha li tenyetsehe haholo ha li le tlas'a khatello ea ho shear. Sena se bolela hore liphahlo tse entsoeng ka li-ether tsa cellulose li lula li tsitsitse 'me ha li tenyetsehe nakong ea ts'ebeliso, e leng se fellang ka botenya bo tšoanang ba ho roala. Sena se boetse se thusa ho fokotsa ho rotha ha metsi le ho fokotsa tlhoko ea ho roala hape, e leng se etsang hore ts'ebetso ea ho roala e sebetse hantle haholoanyane.
Molemo o mong oa ho sebelisa li-ether tsa cellulose e le li-thickeners ke hore li ntlafatsa litšobotsi tsa phallo. Li-coat tse entsoeng ka li-ether tsa cellulose li na le litšobotsi tse ntle tsa phallo le ho leka-lekanya, ho bolelang hore li hasana ka ho lekana holim'a bokaholimo ba substrate, e leng se fellang ka bokaholimo bo boreleli. Thepa ena e bohlokoa haholo bakeng sa li-coat tse hlokang ponahalo e ts'oanang, joalo ka pente ea lebota.
Li-ether tsa cellulose li ka boela tsa ntlafatsa ho tšoarella ha lipehelo tse thehiloeng metsing. Li etsa filimi e tšesaane holim'a substrate e thusang ho thibela metsi le lintho tse ling ho kenella ka har'a peterole. Thepa ena e thusa haholo bakeng sa lipehelo tse pepesehetseng maemo a thata, joalo ka lipehelo tsa kantle. Ho phaella moo, li-ether tsa cellulose li ntlafatsa ho khomarela ha peterole holim'a substrate, e leng se fellang ka peterole e tšoarellang nako e telele le e matla.
Molemo o mong oa bohlokoa oa ho sebelisa li-ether tsa cellulose e le li-thickeners ke ho ba mosa ho tikolohong. Cellulose ether e entsoe ka thepa e tala ea tlhaho 'me e mosa ho tikolohong. Ka hona, e sebelisoa haholo ho penteng e tala 'me ke mokhoa o mong o mosa ho tikolohong ho feta pente ea setso.

Li-ether tsa cellulose ke li-thickeners tsa bohlokoa indastering ea li-coat tse thehiloeng metsing. Li fana ka taolo e ntle ea viscosity, litšobotsi tse ntlafetseng tsa phallo, ho tšoarella ho eketsehileng 'me li sireletsa tikoloho. Li-coat tse thehiloeng metsing tse entsoeng ka li-ether tsa cellulose li na le melemo e mengata 'me li ntse li tuma haholo indastering ea li-coat. Bahlahisi ba li-coat ba tlameha ho tsoela pele ho tsetela lipatlisisong le nts'etsopele ho ntlafatsa ts'ebetso ea li-ether tsa cellulose le ho atolosa mefuta ea tsona ea ts'ebeliso.
