Hydroxyethylcellulose (HEC) ke ether ea cellulose e qhibilihang e seng ea ionic e sebelisoang haholo liindastering tse fapaneng. HEC e nkiloe ho cellulose ea tlhaho 'me e fetotsoe hore e be le lihlopha tsa hydroxyethyl mokokotlong oa cellulose. Phetoho ena e etsa hore HEC e qhibilihe haholo metsing le li-solvents tse ling tsa polar, e leng se etsang hore e be polymer e loketseng lits'ebetso tse fapaneng.
E 'ngoe ea tšebeliso ea mantlha ea HEC ke ho ba sekhomaretsi le sekhomaretsi lihlahisoa tse fapaneng tsa bareki le tsa indasteri. HEC e sebelisoa hangata litlolong le lihlahisoa tsa tlhokomelo ea botho tse kang li-shampoo, litlolo le li-toothpaste ho fana ka ho teteana le botsitso. E boetse e sebelisoa penteng, liphahlong le likhomaretsi ho fana ka thepa ea sekhomaretsi le ho ntlafatsa ho hanyetsa mongobo.
HEC ke motheo o sebetsang ka ho fetisisa bakeng sa lihlahisoa tsena ka lebaka la bokhoni ba eona ba ho eketsa ho teteana lits'ebetsong tse thehiloeng metsing ntle le ho ama thepa e meng ea lihlahisoa haholo. Ka ho eketsa HEC lihlahisoa tsena, bahlahisi ba ka fetola botenya, sebopeho le botsitso ba lihlahisoa tsa bona ho fihlela likhetho tsa bareki le litlhoko tsa indasteri.
Tšebeliso e 'ngoe ea bohlokoa ea HEC e indastering ea meriana. HEC ke motsoako o tloaelehileng lihlahisoa tse ngata tsa meriana, ho kenyeletsoa matlapa, li-capsule le litsamaiso tsa ho fana ka meriana. Ka lebaka la bokhoni ba tsona ba ho fetola rheology le thepa ea ho ruruha ea mefuta ea litekanyetso, HEC e ka ntlafatsa ho fumaneha ha metsoako e sebetsang le ho ntlafatsa taolo ea ho lokolloa ha meriana. HEC e boetse e sebelisoa ho ntlafatsa botsitso ba li-emulsion le li-suspension mefuteng ea meriana.
Indastering ea lijo, HEC e sebelisoa e le setefatsi le sehatsetsi lihlahisoa tse fapaneng tsa lijo, ho kenyeletsoa lisoso, litlolo le lihlahisoa tsa lebese. HEC ke motsoako o sireletsehileng, oa tlhaho o amohetsoeng hore o sebelisoe lijong ke mekhatlo ea taolo lefatšeng ka bophara. E boetse e sebelisoa e le sebaka sa mafura lijong tse nang le mafura a tlase, e leng se fanang ka sebopeho le maikutlo a molomo a tšoanang le lihlahisoa tse nang le mafura a felletseng.
HEC e boetse e sebelisoa indastering ea kaho e le seteishene le sehokelo lihlahisoa tse etsang samente tse kang li-grout, li-mortar le likhomaretsi. Litšobotsi tsa thixotropic tsa HEC li etsa hore e be motsoako o motle bakeng sa lihlahisoa tsena, li li lumella ho lula sebakeng sa tsona le ho thibela ho thekesela kapa ho lula. HEC e na le ho khomarela ho betere le ho hanyetsa metsi, e leng se etsang hore e be motsoako oa bohlokoa lihlahisoa tse thibelang metsi le ho koala.
Hydroxyethyl cellulose ke ether ea cellulose e qhibilihang e seng ionic e nang le mefuta e mengata ea lits'ebetso liindastering tse fapaneng. HEC ke karolo e feto-fetohang le ea bohlokoa lihlahisoa tse ngata tsa bareki le tsa indasteri, e fanang ka botsitso bo ntlafalitsoeng, viscosity, le taolo ea ho lokolloa ha lithethefatsi. HEC ke motsoako oa tlhaho, o sireletsehileng le o mosa tikolohong o amohetsoeng hore o sebelisoe ke linaha tse ngata lefatšeng ka bophara. Thepa ea eona e ikhethang le ho feto-fetoha ha eona ho etsa hore HEC e be motsoako oa bohlokoa lihlahisoa le liindastering tse ngata.
