Viscosity ke thepa ea bohlokoa ho utloisisa boitšoaro ba maro, ho kenyelletsa le cellulose ethers.Cellulose ethers ke sehlopha sa metsoako ea lintho tse phelang e nkiloeng ho cellulose, e leng polima ea tlhaho e fumanoang limela.Li-ether tsena li sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea tsona e ikhethang, ho kenyelletsa le phetoho ea viscosity.
1. Kenyelletso ea Cellulose Ethers:
Li-cellulose ethers ke li-derivatives tsa selulose tse fumanoang ka ho fetola lik'hemik'hale.Mehlala e tloaelehileng e kenyelletsa methylcellulose, ethylcellulose, hydroxypropylcellulose, le hydroxyethylcellulose.Lik'hemik'hale tsena li khetholloa ke boima ba tsona bo phahameng ba limolek'hule le boteng ba lihlopha tsa hydroxyl, tse etsang hore li qhibilihe ka metsing le lihlahisoa tsa tlhaho ho ea ka likhato tse sa tšoaneng.
2. Bohlokoa ba Viscosity:
Viscosity ke tekanyo ea hore mokelikeli o hana ho phalla.Tabeng ea li-cellulose ethers, viscosity e bapala karolo ea bohlokoa ho tseba hore na li loketse lits'ebetso tse fapaneng.Mohlala, indastering ea lijo, viscosity e ama sebopeho le melomo ea lihlahisoa tse kang li-sauces le liaparo.Meriana ea meriana, e susumetsa ho tsitsisa le ho ata ha mafura le litlolo.Kahoo, ho utloisisa le ho laola viscosity ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea sehlahisoa.
3. Lintlha tse Amang Viscosity:
Lintlha tse 'maloa li susumetsa viscosity ea cellulose ethers:
Boima ba Molek'hule: Boima bo phahameng ba limolek'hule ka kakaretso bo lebisa ho viscosity e phahameng ka lebaka la ho kenngoa ha ketane.
Boemo ba Phatlalatso: Tekanyo ea ho kenya sebaka sa lihlopha tsa ether mokokotlong oa cellulose e ama ho qhibiliha, ka lebaka leo, viscosity.
Thempereichara: Viscosity hangata e fokotseha ka mocheso o ntseng o eketseha ka lebaka la ho fokotseha ha likamano tsa limolek'hule.
Ho tsepamisa maikutlo: Maemo a phahameng a li-cellulose ethers hangata a baka viscosity e phahameng, ho latela kamano e se nang moeli.
4. Mekhoa ea ho Lekanya:
Viscosity e ka lekanyetsoa ka mekhoa e fapaneng:
Rotational Viscometry: Hangata e sebelisoa bakeng sa tharollo le ho emisoa, mokhoa ona o kenyelletsa ho metha torque e hlokehang ho potoloha seluloana ka har'a mokelikeli.
Capillary Viscometry: Mokhoa ona o lekanya nako e nkiloeng bakeng sa hore mokelikeli o phalle ka har'a tube ea capillary tlas'a khatello e itseng ea khatello.
Rheology: Litekanyo tsa ramatiki li fana ka temohisiso ea hore na lintho li holofala joang ha motho a le tlas'a khatello ea maikutlo, ho kenyelletsa ho kuta le viscosity e telele.
5. Lisebelisoa tsa Cellulose Ethers:
Li-cellulose ethers li fumana lits'ebetso ho tsoa liindasteri tse fapaneng:
Lijo: E sebelisoa e le li-thickeners, stabilizers, le emulsifiers lihlahisoa tse kang ice cream, yogurt le liaparo tsa salate.
Meriana ea Meriana: E hiriloe e le ba tlamahanyang, li-disintegrants, le baetsi ba lifilimi mefuteng ea lipilisi, litlolo, le ho emisoa.
Kaho: E eketsoa ho samente le seretse ho ntlafatsa ts'ebetso, ho boloka metsi, le ho khomarela.
Tlhokomelo ea Botho: E kenyelelitsoe litlolong, li-shampoo, le litlolo bakeng sa thepa ea tsona ea ho tenya le ea li-gelling.
6. Mekhoa le Liqholotso tsa Kamoso:
Tlhokahalo ea li-cellulose ethers e lebelletsoe ho hola, e tsamaisoa ke ho eketseha ha lits'ebetso ho k'hemistri e tala, biomedicine le lisebelisoa tse tsoetseng pele.Leha ho le joalo, liqholotso tse kang tlholisano ea litšenyehelo, mathata a taolo, le tlhokeho ea mekhoa e tsitsitseng ea ho fumana le ho hlahisa lihlahisoa li ntse li le teng.
7. Qetello:
viscosity ea cellulose ethers ke parameter ea bohlokoa e susumetsang ts'ebetso ea bona lits'ebetsong tse fapaneng.Ho utloisisa lintlha tse amang viscosity le ho sebelisa mekhoa e nepahetseng ea ho lekanya ho bohlokoa bakeng sa ho ntlafatsa libopeho le lits'ebetso tsa sehlahisoa.Ha liindasteri li ntse li tsoela pele ho ntlafatsa, li-cellulose ethers li kanna tsa bapala karolo ea bohlokoa ho theha bokamoso ba mahlale a thepa le theknoloji.
viscosity ea cellulose ethers ke ntlha e rarahaneng empa e le ea bohlokoa e amang ts'ebetso ea tsona ho pholletsa le liindasteri tse fapaneng.Ka ho utloisisa bohlokoa ba eona, lintlha tse e susumetsang, mekhoa ea ho lekanya, le ts'ebeliso, bafuputsi le litsebi ba ka sebelisa li-cellulose ether ka katleho mafapheng a fapaneng, ba kenya letsoho ntlafatsong ea mahlale a thepa le theknoloji.
