Ethyl Cellulose- EC mofani oa thepa

Ethyl cellulose ke polima e sa keneng ka metsi e tsoang ho cellulose, biopolymer ea tlhaho e fumanehang maboteng a lisele tsa semela. E sebelisoa haholo liindastering tse fapaneng, ho kenyelletsa le tsa meriana, lijo, le tlhokomelo ea motho ka mong, ka lebaka la thepa ea eona e ikhethang, ho kenyelletsa le ho qhibiliha, bokhoni ba ho etsa lifilimi le chefo e tlase. Sengoliloeng sena se tla tšohla thepa, motsoako le ts'ebeliso ea ethyl cellulose.

Properties of Ethyl Cellulose Ethyl cellulose ke thepa ea thermoplastic e qhibilihang ka har'a metsoako ea lintho tse phelang, joalo ka ethanol, empa e sa qhibilihe ka metsing. Ho qhibiliha ha ethyl cellulose ho ka fetoloa ka ho fetola boemo ba eona, e bolelang palo ea lihlopha tsa ethyl ka yuniti ea tsoekere ka molek'hule ea cellulose. Ethyl cellulose e nang le boemo bo phahameng ba ho e nkela sebaka e qhibiliha haholoanyane ka har'a metsoako ea lintho tse phelang, athe tse nang le sebaka se tlase ha li qhibilihe.

Ethyl cellulose e tsejoa ka bokhoni ba eona bo botle ba ho etsa lifilimi 'me e ka sebelisoa ho etsa filimi e ts'oanang le e tsitsitseng. Lintho tse entsoeng ka filimi ea ethyl cellulose li ka ntlafatsoa ka ho eketsehileng ka ho eketsa li-plasticizers, tse kang dibutyl phthalate kapa triacetin, e leng ho eketsang ho feto-fetoha ha filimi le elasticity. Lifilimi tsa Ethyl cellulose li atisa ho sebelisoa indastering ea meriana e le liaparo tsa matlapa, li-capsules le granules.

Synthesis ea Ethyl Cellulose Ethyl cellulose e entsoe ka ho arabela selulose ka ethyl chloride ka pel'a motheo, joalo ka sodium hydroxide kapa potassium hydroxide. Boitšoaro bo kenyelletsa ho nkela lihlopha tsa hydroxyl sebakeng sa molek'hule ea cellulose ka lihlopha tsa ethyl, e leng se etsang hore ho thehoe cellulose ea ethyl. Tekanyo ea ho fetola e ka laoloa ka ho lokisa maemo a karabelo, joalo ka mahloriso a li-reactants le nako ea karabelo.

Likopo tsa Ethyl Cellulose Pharmaceuticals: Ethyl cellulose e sebelisoa haholo indastering ea meriana ka lebaka la bokhoni ba eona bo botle ba ho etsa lifilimi le chefo e tlase. E sebelisoa e le lisebelisoa tsa ho roala bakeng sa matlapa, li-capsules le granules, tse ntlafatsang botsitso ba tsona le ho li thibela ho senyeha ka har'a pampitšana ea gastrointestinal. Liaparo tsa ethyl cellulose le tsona li ka sebelisoa ho laola ho lokolloa ha lithethefatsi ka ho fetola sekhahla sa ho qhibiliha ha tsona.

Lijo: Ethyl cellulose e sebelisoa e le tlatsetso ea lijo ho ntlafatsa sebopeho le botsitso ba lijo. Hangata e sebelisoa e le sekontiri, se tlamang, le se tsitsitseng lijong tse phehiloeng, tse kang li-sauces, li-dressings le lintho tse apehoang. Ethyl cellulose e ka boela ea sebelisoa e le seaparo sa litholoana le meroho ho lelefatsa bophelo ba tsona le ho thibela ho senyeha.

Tlhokomelo ea Motho: Ethyl cellulose e sebelisoa lihlahisoa tse fapaneng tsa tlhokomelo ea motho, joalo ka litlolo, li-shampoo le litlolo, ka lebaka la bokhoni ba eona ba ho etsa filimi le thepa ea eona e thibelang metsi. E atisa ho sebelisoa e le setepi le se tsitsitseng ho litlolo 'me e ka boela ea sebelisoa e le moemeli oa ho etsa lifilimi ho li-sprays tsa moriri le lihlahisoa tsa setaele.

Lits'ebetso Tse Ling: Ethyl cellulose e sebelisoa lits'ebetsong tse ling tse fapaneng, joalo ka li-inks, lirafshoa, likhomaretsi le lipente. Hangata e sebelisoa e le sekontiri ka li-coatings le joalo ka sekontiri sa li-inks. Ethyl cellulose e ka boela ea sebelisoa e le sekontiri se sa keneleng metsi bakeng sa pampiri le joalo ka setlamo sa lirafshoa.

Ka bokhutšoanyane, ethyl cellulose ke polymer e sa tsitsang ka metsi e tsoang ho selulose e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa meriana, lijo le tlhokomelo ea motho. E tsebahala ka bokhoni ba eona bo botle ba ho etsa lifilimi, chefo e tlase, le thepa e thibelang metsi, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng.
