Hydroxyethylcellulose (HEC) ke polima e se nang ionic, e qhibilihang ka metsing e tsoang selulose, e sebelisoang haholo liindastering tse fapaneng tse kang litlolo, meriana, lijo le masela.Litšobotsi tsa eona tse ikhethang li etsa hore e be motsoako oa bohlokoa mekhoeng e mengata, ho kenyeletsoa e le motenya, emulsifier le stabilizer.E 'ngoe ea mathata a tloaelehileng a amanang le hydroxyethylcellulose ke sebopeho sa eona sa ho khomarela.
Ho utloisisa Hydroxyethylcellulose (HEC)
Sebopeho le Thepa
HEC e entsoe ka etherification ea cellulose e nang le ethylene oxide, e hlahisang polymer ea hydrophilic e nang le thepa e ntle ea ho tlama metsi.Tekanyo ea phetoho (DS) ea lihlopha tsa hydroxyethyl mokokotlong oa cellulose e etsa qeto ea ho qhibiliha ha eona, viscosity, le litšobotsi tse ling.Ka kakaretso, litekanyetso tse phahameng tsa DS li lebisa ho eketsa ho qhibiliha ha metsi le viscosity.
Lisebelisoa
Litlolo: HEC e sebelisoa haholo litlolong tsa litlolo tse kang litlolo, litlolo, li-shampoo le li-gel e le ntho e matlafatsang, e emulsifier le e tsitsitseng.E ntlafatsa sebopeho sa sehlahisoa, e fana ka boreleli, 'me e ntlafatsa boiphihlelo ba kutlo ka kakaretso.
Meriana: Litlhareng tsa meriana, HEC e sebelisoa ka mefuta e fapaneng ea litekanyetso ho kenyelletsa litlolo, ho emisoa, le lino tse nooang bakeng sa ho tenya le ho emisa thepa ea eona.
Indasteri ea Lijo: HEC e sebelisoa lihlahisoa tsa lijo ho fetola sebopeho, ho tsitsisa li-emulsions, le ho laola viscosity lits'ebetsong tse kang li-sauces, dressings le lino.
Tlhokomelo ea Botho: Ntle le litlolo, HEC e fumana lits'ebetso lihlahisoa tsa tlhokomelo ea motho joalo ka sesepa sa meno, metsoako ea tlhokomelo ea moriri, le lihlahisoa tse haufi-ufi tsa bohloeki.
Lintlha tse Susumetsang ho Khomarela
Tsepamiso ea maikutlo: Likhakanyo tse phahameng tsa HEC li ka etsa hore ho be le ho khomarela ho eketsehileng ka lebaka la ho sebelisana ho hoholo pakeng tsa liketane tsa polymer, e leng se hlahisang tharollo ea viscous haholoanyane.
Thempereichara: Ho khomarela ho ka fapana ho ea ka liphetoho tsa mocheso.Lithempereichara tse phahameng, litharollo tsa HEC li atisa ho ba metsi a mangata, ho fokotsa ho khomarela, ha mocheso o tlaase o ka eketsa viscosity le ho khomarela.
pH: pH e ka susumetsa ho solubility le viscosity ea tharollo ea HEC.Maemo a pH a feteletseng a ka etsa hore HEC e theohe kapa e thehe li-gel, tse amang ho khomarela.
Li-additives: Lisebelisoa tse ling tse entsoeng li ka sebelisana le HEC, li fetola thepa ea eona.Li-surfactants, matsoai le li-electrolyte li ka ama ho solubility le viscosity ea litharollo tsa HEC, ka hona tsa ama ho khomarela.
Maano a ho Laola ho Khomarela
Optimize Formulation: Ho fetola khatello ea HEC le lisebelisoa tse ling ho ka thusa ho laola ho khomarela.Ho lokisa karo-karolelano ea HEC ho likarolo tse ling ho ka fihlela sebopeho se lakatsehang le viscosity.
Taolo ea Mocheso: Ho beha leihlo le ho laola mocheso oa ho sebetsa ho ka susumetsa boitšoaro ba rheological ba tharollo ea HEC, ho fokotsa ho khomarela nakong ea tlhahiso.
Phetoho ea pH: Ho etsa bonnete ba hore metsoako e ka har'a mefuta e nepahetseng ea pH bakeng sa ho qhibiliha le botsitso ba HEC ho ka thibela mathata a kang pula le ho etsoa ha gel, kahoo ho fokotsa ho khomarela.
Tšebeliso ea Lithako Tse Tlatsetsang: Ho kenyelletsa li-additives tse kang thickeners, emollients, kapa humectants ho ka fetola sebopeho le ho fokotsa ho khomarela ha ho ntse ho ntlafatsa ts'ebetso ea kakaretso ea sehlahisoa.
Phokotso ea Boholo ba Particle: Ho lokisa litharollo tsa HEC ka boholo bo botle ba likaroloana ho ka ntlafatsa ho hasana le ho fokotsa ho khomarela ka ho khothalletsa tšebelisano e ntle le lisebelisoa tse ling.
Homogenization: Homogenizing HEC tharollo e ka thusa ho finyella ho hasana ho tšoanang ha polymer, ho fokotsa monyetla oa ho khomarela le ho khomarela.
Hydroxyethylcellulose ke polymer e sebetsang ka mokhoa o fapaneng e nang le lits'ebetso tse ngata ho liindasteri tse fapaneng.Le hoja e fana ka melemo ea bohlokoa e kang ho teteaneng, ho tsitsisa, le ho etsa emulsifying, ho khomarela ka linako tse ling e ka ba ntho e tšoenyang, haholo-holo ha ho etsoa libopeho moo sebopeho le litšobotsi tsa kutlo li leng bohlokoa.Ho utloisisa lintlha tse susumetsang ho khomarela le ho sebelisa mekhoa e nepahetseng ea ho e laola ho ka etsa bonnete ba hore HEC e sebelisoa ka katleho lits'ebetsong tse fapaneng, ho ntlafatsa ts'ebetso ea sehlahisoa le khotsofalo ea bareki.
ha hydroxyethylcellulose e ka bontša ho khomarela tlas'a maemo a itseng, moralo o nepahetseng oa sebopeho, taolo ea mocheso, phetoho ea pH, le tšebeliso ea metsoako e tlatsetsang e ka fokotsa taba ena, e leng se lumellang tšebeliso e nepahetseng ea HEC lits'ebetsong tse sa tšoaneng.
