Li-cellulose ethers

Li-cellulose ethers ke lelapa la li-polysaccharides tse nkiloeng ho selulose, e leng polymer ea tlhaho e ngata ka ho fetisisa lefatšeng. Li qhibiliha ka metsing 'me li na le lisebelisoa tse ngata tse fapaneng liindastering tse fapaneng, ho kenyeletsa lijo, meriana, litlolo le kaho. Sehloohong sena, re tla tšohla thepa, tlhahiso le ts'ebeliso ea li-cellulose ethers ka botlalo.

Thepa ea Cellulose Ethers

Li-cellulose ethers li na le motsoako o ikhethang oa thepa o li etsang hore li be molemo haholo lits'ebetsong tse fapaneng. Tse ling tsa likarolo tsa bohlokoa tsa cellulose ethers li kenyelletsa:

Ho qhibiliha ha Metsi: Li-cellulose ethers li qhibiliha haholo ke metsi, e leng se etsang hore ho be bonolo ho li sebelisa tsamaisong ea metsi. Thepa ena e boetse e ba etsa li-thickeners tse sebetsang hantle le li-stabilizers lijong le litlamong tsa meriana.

Lintho Tsa ho Etsa Lifilimi: Li-cellulose ethers li ka etsa lifilimi tse hlakileng, tse tenyetsehang le tse matla ha li qhibiliha metsing. Thepa ena e na le thuso ha ho etsoa lirafshoa, likhomaretsi le lifilimi.

Botsitso ba Lik'hemik'hale: Li-cellulose ethers li tsitsitse lik'hemik'hale 'me li hanyetsa ho senyeha ha likokoana-hloko, e leng se etsang hore li tšoanelehe ho sebelisoa lits'ebetsong tse sa tšoaneng tsa indasteri.

Ha e na Chefo: Li-cellulose ethers ha li chefo 'me li bolokehile hore li ka sebelisoa lijong, meriana le lihlahisoa tsa tlhokomelo ea motho.

Tlhahiso ea Cellulose Ethers

Li-cellulose ethers li hlahisoa ka ho fetola selulose ka karabelo ea lik'hemik'hale ka lihlopha tse fapaneng tse sebetsang. Mefuta e atileng haholo ea li-cellulose ethers e kenyelletsa:

Methylcellulose (MC): Methylcellulose e hlahisoa ka ho arabela selulose ka methyl chloride le sodium hydroxide. E sebelisoa haholo e le motenya le stabilizer lijong le metsoako ea meriana.

Hydroxypropyl Cellulose (HPC): Hydroxypropyl cellulose e hlahisoa ka ho arabela selulose ka propylene oxide le hydrochloric acid. E sebelisoa e le sekontiri, emulsifier le setenya lijong, meriana, le lihlahisoa tsa tlhokomelo ea motho.

Ethylcellulose (EC): Ethylcellulose e hlahisoa ka ho arabela selulose ka ethyl chloride le sodium hydroxide. E sebelisoa e le setlamo, sa pele sa filimi, le se koahelang indasteri ea meriana le ea tlhokomelo ea motho ka mong.

Carboxymethyl Cellulose (CMC): Carboxymethyl cellulose e hlahisoa ka ho arabela selulose ka chloroacetic acid le sodium hydroxide. E sebelisoa e le setei, se tsitsitseng, le emulsifier indastering ea lijo, ea meriana le ea tlhokomelo ea botho.

Hydroxyethyl Cellulose (HEC): Hydroxyethyl cellulose e hlahisoa ka ho arabela selulose ka ethylene oxide le sodium hydroxide. E sebelisoa e le setei, se tsitsitseng, le emulsifier indastering ea lijo, ea meriana le ea tlhokomelo ea botho.

Lisebelisoa tsa Cellulose Ethers

Cellulose ethers e na le mefuta e mengata ea ts'ebeliso liindastering tse fapaneng, ho kenyelletsa:

Indasteri ea Lijo: Li-cellulose ethers li sebelisoa haholo e le li-thickeners, stabilizers, le emulsifiers ha ho etsoa lijo. Li sebelisoa lihlahisoa tse kang ice cream, li-sauces, liaparo le lintho tse apehoang.

Indasteri ea Meriana: Li-cellulose ethers li sebelisoa e le li-binders, disintegrants, le li-coatings mefuteng ea meriana. Li sebelisoa ka matlapa, li-capsules le mefuta e meng ea litekanyetso tse tiileng.

Indasteri ea Tlhokomelo ea Motho: Li-cellulose ethers li sebelisoa e le li-thickeners, stabilizers, le emulsifiers lihlahisoa tsa tlhokomelo ea botho tse kang li-shampoo, litlolo le litlolo.

Indasteri ea Kaho: Li-cellulose ethers li sebelisoa e le lintho tse bolokang metsi, li-thickeners le li tlamahanyang thepa ea kaho e kang samente, seretse.
