Carboxy methyl hydroxyethyl cellulose ke eng?

Carboxymethyl hydroxyethyl cellulose (CMHEC) ke polymer e qhibilihang ka metsi e sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri le tsa bareki. Ke mofuta o fetotsoeng oa selulose, polima ea tlhaho e fumanehang limeleng ebile ke lintho tse ngata tse phelang lefatšeng. CHEC ke thepa e feto-fetohang e nkoang e le ea bohlokoa ka lebaka la thepa ea eona e teteaneng, e tlamang le e tsitsitseng, hammoho le ho senyeha ha eona le ho se be chefo.

CHEC e hlahisoa ka ho fetola selulose ka lihlopha tsa carboxymethyl le hydroxyethyl. Carboxymethylation e kenyelletsa ho nkela lihlopha tse ling tsa hydroxyl sebakeng sa molek'hule ea cellulose ka lihlopha tsa carboxymethyl, tse qosoang hampe ebe li etsa hore molek'hule e qhibilihe ka metsing. Hydroxyethylation e kenyelletsa ho eketsa lihlopha tsa hydroxyethyl molek'hule ea cellulose, e ntlafatsang thepa ea eona ea ho boloka metsi le ho ntlafatsa ho lumellana ha eona le lisebelisoa tse ling.

CHEC e sebelisoa mefuteng e mengata ea lits'ebetso, ho kenyeletsoa le makaleng a lijo, a meriana, a litlolo le a indasteri. Tse ling tsa lisebelisoa tsa eona tsa mantlha li hlalositsoe ka tlase:

1. Indasteri ea Lijo: CMHEC e sebelisoa e le setepi, se tsitsisa, le emulsifier lihlahisoa tse fapaneng tsa lijo, ho kenyeletsoa li-sauces, li-dressings le lintho tse halikiloeng. E ka thusa ho ntlafatsa sebopeho, ho tsitsa le ho phela ha lihlahisoa tsena.
2. Indasteri ea Litlhare: CMHEC e sebelisoa e le se tlamellang, se senyang, le se teteaneng mekhoeng ea meriana, joalo ka matlapa, li-capsules le li-suspensions. E ka thusa ho ntlafatsa phallo, khatello, le ho qhibiliha ha libopeho tsena.
3. Indasteri ea Litlolo: CMHEC e sebelisoa e le setenya, se tsitsitseng, le emulsifier litlolong tsa litlolo, joalo ka litlolo, litlolo, le ligel. E ka thusa ho ntlafatsa sebopeho, ho ata, le botsitso ba lihlahisoa tsena.
4. Likopo tsa Indasteri: CMHEC e sebelisoa lits'ebetsong tse fapaneng tsa indasteri, ho kenyeletsoa joalo ka se tlamella le ho tiisa lipente, likhomaretsi le liphahlo. E ka thusa ho ntlafatsa viscosity, adhesion, le thepa ea ho hanyetsa metsi ea lihlahisoa tsena.

CHEC e nkoa e le ea bohlokoa ka lebaka la ho senyeha ha eona le ho se chefo, e leng se etsang hore e be sebaka se seng se se nang tikoloho ho feta li-polymer tsa maiketsetso. E boetse e nkoa e sireletsehile bakeng sa ho sebelisoa lijong, meriana le lihlahisoa tsa litlolo, kaha ha e na allergenic ebile ha e halefise letlalo le lera la mucous.

carboxymethyl hydroxyethyl cellulose (CMHEC) ke polymer e qhibilihang ka metsing e sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri le tsa bareki. Botenya ba eona bo khabane, bo tlamang le bo tsitsisa, hammoho le ho senyeha ha eona le ho se chefo, ho etsa hore e be thepa e sebetsang ka mefuta-futa le e baballang tikoloho e nkoang e le ea bohlokoa liindastering tse ngata.
