Fana ka Ethyl Hydroxyethyl Cellulose

Ethyl hydroxyethyl cellulose (EHEC) ke motsoako oa selulose o fetotsoeng o kopanyang thepa ea ethyl cellulose (EC) le hydroxyethyl cellulose (HEC). Hangata e sebelisoa e le ntho e tiisang, e tlamang le ea ho etsa lifilimi liindastering tse fapa-fapaneng, ho kenyeletsoa meriana, litlolo, lihlahisoa tsa tlhokomelo ea motho, le liaparo.

EHEC e atisa ho hlahisoa ka ho itšoara ka ethyl chloride le hydroxyethyl cellulose tlas'a maemo a laoloang. Phetoho ena ea lik'hemik'hale e hlahisa lihlopha tsa ethyl mokokotlong oa hydroxyethyl cellulose, e hlahisang sehlahisoa se nang le matla a ho qhibiliha, viscosity, le thepa ea ho etsa filimi ha e bapisoa le lihlahisoa tse sa fetoloang tsa cellulose.

Lintho tsa bohlokoa le litšoaneleho tsa ethyl hydroxyethyl cellulose (EHEC) li kenyelletsa:

1. Moemeli oa Thickening: EHEC e sebetsa e le moemeli ea sebetsang hantle ka har'a litharollo tsa metsi, ho eketsa viscosity le ho ntlafatsa thepa ea rheological ea metsoako.
2. Binder: EHEC e sebelisoa e le tlamahano ka mefuta e tiileng ea litekanyetso tse kang matlapa le li-granules mefuteng ea meriana. E thusa ho ntlafatsa momahano le ho hatelloa ha li-powders, ho thusa ho thehoa ha matlapa a nang le lithethefatsi tse tšoanang le thepa ea ho arohana.
3. Filimi ea Pele: EHEC e ka etsa lifilimi tse tenyetsehang le tse tšoarellang ha li sebelisoa holimo. Thepa ena e etsa hore e be molemo ka ho roala, lipente, li-adhesive, le lihlahisoa tsa tlhokomelo ea botho moo filimi e sireletsang kapa e khabisitsoeng e lakatsoang.
4. Ho qhibiliha ha Metsi: EHEC e bonts'a ho qhibiliha ha metsi ho ntlafetseng ha ho bapisoa le cellulose ea ethyl, e leng ho lumellang ho hasana habonolo le ho kenngoa ka har'a metsoako ea metsi.
5. Ho lumellana: EHEC e lumellana le mefuta e mengata ea lisebelisoa tse ling tse atisang ho sebelisoa meriana, litlolo le liphahlo, ho akarelletsa le lipolymers tse ling, li-plasticizers, surfactants, le metsoako e sebetsang.
6. Botsitso: EHEC e tsitsitse tlas'a maemo a mangata a pH le mocheso, ho etsa hore e loketse ho sebelisoa ka mefuta e sa tšoaneng e nang le litlhoko tse fapaneng tsa ho sebetsa.
7. Ho feto-fetoha ha maemo: EHEC e fumana lits'ebetso mefuteng e fapaneng ea lihlahisoa, ho kenyeletsoa matlapa a meriana, litlolo tsa lihlooho, lipente, lirafshoa, li-adhesives, le lihlahisoa tsa tlhokomelo ea botho, ka lebaka la thepa ea eona e fapaneng le ho lumellana le lisebelisoa tse ling.

Ka kakaretso, ethyl hydroxyethyl cellulose (EHEC) ke motsoako oa bohlokoa oa selulose o nang le mefuta e mengata ea likopo ho pholletsa le liindasteri tse fapaneng, o fana ka lisebelisoa tse ntlafetseng tsa solubility, viscosity le ho etsa lifilimi ha li bapisoa le lihlahisoa tse sa fetoloang tsa selulose.
