Viscosity ea hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ke polymer ea nonionic, e qhibilihang ka metsing e sebelisoang haholo e le setei, se tsitsitseng le se tlamang liindasteri tse fapaneng, ho kenyeletsoa tsa meriana, litlolo le kaho.Viscosity ea eona e phetha karolo ea bohlokoa ho khethollang ts'ebetso ea eona lits'ebetsong tsena.

The viscosity ea HEC e khethoa ke lintlha tse 'maloa, ho kenyelletsa tekanyo ea eona ea ho fetola (DS), boima ba limolek'hule, mahloriso le pH.Tekanyo ea ho fetola e bolela palo ea lihlopha tsa hydroxyethyl tse kentsoeng molek'hule ea cellulose, ha boima ba molek'hule bo bolela boholo ba liketane tsa polymer.Khatiso ea HEC ka tharollo e boetse e ama viscosity ea eona, ka ho tsepamisa maikutlo ho phahameng ho hlahisang li-viscosity tse phahameng.PH ea tharollo le eona e ka ba le tšusumetso ho viscosity, ka litekanyetso tse phahameng tsa pH ka kakaretso li bakang li-viscosity tse tlase.

The viscosity ea HEC e ka lekanyetsoa ho sebelisa viscometer, e lekanyang ho hanyetsa ha mokelikeli ho phalla.Mefuta e fapaneng ea li-viscometers e ka sebelisoa, ho kenyelletsa le li-viscometers tse potolohang le li-capillary viscometers, ho itšetlehile ka ts'ebeliso e khethehileng le mefuta e mengata ea thahasello.

Ka kakaretso, viscosity e phahameng HEC e khethoa lits'ebetsong moo ho teteaneng le ho tsitsisa ho leng bohlokoa, joalo ka lihlahisoa tsa meriana, litlolo, le lihlahisoa tsa tlhokomelo ea botho.Ka mohlala, HEC e nang le viscosity e phahameng e atisa ho sebelisoa ka li-shampoo le li-conditioner ho ntlafatsa sebopeho sa tsona le ts'ebetso ea tsona, hammoho le litlolo le litlolo ho fana ka maikutlo a boreleli, a mabothobotho.

Indastering ea kaho, HEC e sebelisoa e le setsi sa ho thibela metsi le ho boloka metsi lihlahisoa tse entsoeng ka samente, tse kang seretse, li-grouts le konkreite.The viscosity ea HEC lits'ebetsong tsena ke ea bohlokoa bakeng sa ho finyella mosebetsi o lakatsehang, ho khomarela, le ho tsitsa ha sehlahisoa sa ho qetela.

Viscosity ea HEC e ka boela ea fetoloa ka mekhoa e fapaneng ea lik'hemik'hale le ea 'mele, ho kenyelletsa le crosslinking, acid hydrolysis, le ho kopanya le li-polymers tse ling.Liphetoho tsena li ka fetola thepa ea HEC 'me tsa fella ka ts'ebetso e ntlafetseng lits'ebetsong tse itseng.

Ka kakaretso, viscosity ea HEC ke ntlha ea bohlokoa ho khethollang ts'ebetso ea eona lits'ebetsong tse fapaneng.Tekanyo ea ho nkela sebaka, boima ba limolek'hule, mahloriso, le pH kaofela li na le seabo sa ho khetholla viscosity ea eona, e ka meloang ho sebelisoa viscometer.Liindasteri le lits'ebetso tse fapaneng li ka hloka maemo a fapaneng a viscosity, 'me ho ka etsoa liphetoho ho HEC ho ntlafatsa ts'ebetso ea eona lits'ebetsong tse ikhethileng.
