Hydroxyethylcellulose (HEC) ke polymer e sa tloaelehang, e qhibilihang ka metsing e tsoang ho selulose. Ka lebaka la thepa ea eona e ikhethang ea rheological, e sebelisoa hangata liindastering tse fapaneng ho kenyelletsa le tsa meriana, litlolo le kaho. E 'ngoe ea likarolo tsa bohlokoa tsa hydroxyethyl cellulose ke viscosity ea eona, e bapalang karolo ea bohlokoa ho lekola ts'ebetso ea eona lits'ebetsong tse fapaneng.
Viscosity ke tekanyo ea hore mokelikeli o hana ho phalla. Tabeng ea hydroxyethylcellulose, viscosity ea eona e angoa ke lintlha tse 'maloa, ho kenyelletsa mahloriso, mocheso le sekhahla sa ho kuta. Ho utloisisa lintlha tsena ho bohlokoa ho ntlafatsa tšebeliso ea HEC mekhoeng e fapaneng.
Viscosity ea hydroxyethylcellulose e itšetlehile haholo ka mahloriso a eona ka tharollo. Ka kakaretso, ha mahloriso a HEC a ntse a eketseha, viscosity ea eona e boetse e eketseha. Boitšoaro bona bo tloaelehile ka tharollo ea polymer 'me hangata bo hlalosoa ke mohlala oa molao oa matla o amanang le viscosity le mahloriso.
Mocheso o boetse o na le phello e kholo ho viscosity ea tharollo ea hydroxyethyl cellulose. Maemong a mangata, viscosity e fokotseha ka mocheso o ntseng o eketseha. Boikutlo bona ba mocheso bo bohlokoa bakeng sa lits'ebetso moo lisebelisoa li hlokang ho fetoha ka har'a viscosity, joalo ka nakong ea tlhahiso kapa ha e sebelisoa libakeng tse fapaneng.
Sekhahla sa shear ke ntlha e 'ngoe ea bohlokoa e amang viscosity ea hydroxyethyl cellulose. Sekhahla sa shear se bolela lebelo leo ka lona maro a haufi a tsamaeang a ipapisitse le a mang. The viscosity ea tharollo ea HEC hangata e bonts'a boitšoaro ba ho kuta, ho bolelang hore ha sekhahla sa ho kuta se ntse se eketseha, viscosity ea fokotseha. Thepa ena e na le molemo lits'ebetsong tse kang li-coatings le li-adhesives moo ho hlokahalang habonolo.
Boima ba molek'hule ea hydroxyethyl cellulose le bona bo lekanya viscosity ea eona. Li-HEC tse phahameng tsa limolek'hule li atisa ho ba le li-viscosity tse phahameng ka nako e itseng. Tšobotsi ena ke ea bohlokoa ha u khetha sehlopha se itseng sa HEC bakeng sa kopo e itseng.
Mekhahlelong ea meriana, hydroxyethylcellulose e sebelisoa hangata joalo ka ntho e tenya mefuteng ea litekanyetso tsa molomo le tsa lihlooho. The viscosity ea HEC e tiisa ho emisoa ho nepahetseng ha likaroloana 'me e fana ka ts'ebetso e hlokahalang bakeng sa dosing e bonolo. Ho feta moo, boitšoaro ba ho kuta ba HEC bo ka ntlafatsa ho ata ha metsoako ea lihlooho.
Indasteri ea litlolo, hydroxyethylcellulose e sebelisoa lihlahisoa tse fapaneng, ho kenyelletsa li-shampoo, litlolo le litlolo. Thepa ea eona ea ho fetola viscosity e thusa ho ntlafatsa botsitso le sebopeho sa libopeho tsena, ka tsela eo e ntlafatsa boiphihlelo ba basebelisi ka kakaretso.
Lefapheng la kaho, hydroxyethylcellulose hangata e sebelisoa e le motenya lihlahisoa tse entsoeng ka samente. The viscosity ea HEC e thusa ho laola ho phalla le ho sebetsa ha thepa nakong ea kopo. Sena se bohlokoa haholo bakeng sa lits'ebetso tse joalo ka likhomaretsi tsa lithaele le li-grouts.
Viscosity ea hydroxyethyl cellulose ke parameter ea bohlokoa e amang ts'ebetso ea eona lits'ebetsong tse fapaneng. Ho utloisisa lintlha tse susumetsang viscosity, joalo ka mahloriso, mocheso le sekhahla sa ho kuta, ho bohlokoa ho ntlafatsa ts'ebeliso ea HEC liindasteri tse fapaneng. Joalo ka polymer e feto-fetohang, hydroxyethyl cellulose e ntse e tsoela pele ho bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea lihlahisoa tse fapaneng liindastering tse fapaneng.
