Ho tsikinyeha ha hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ke polymer e seng ea ionic, e qhibilihang ka metsing e sebelisoang haholo e le sethibela-mafu, se tsitsitseng le se kopanyang liindastering tse fapaneng, ho kenyeletsoa meriana, litlolo le kaho. Ho teteana ha eona ho bapala karolo ea bohlokoa ho khetholleng ts'ebetso ea eona lits'ebetsong tsena.

Ho teteana ha HEC ho laolwa ke mabaka a 'maloa, ho kenyeletsoa tekanyo ea eona ea phetoho (DS), boima ba limolek'hule, mahloriso le pH. Tekanyo ea phetoho e bolela palo ea lihlopha tsa hydroxyethyl tse ekelitsoeng molek'huleng ea cellulose, ha boima ba limolek'hule bo bolela boholo ba liketane tsa polymer. Ho teteana ha HEC ka har'a tharollo ho boetse ho ama ho teteana ha eona, ka mahloriso a phahameng a fellang ka ho teteana ho hoholo. PH ea tharollo e ka boela ea ba le tšusumetso ho teteana, ka boleng bo phahameng ba pH ka kakaretso bo fellang ka ho teteana ho tlase.

Viscometer ea HEC e ka lekanyetsoa ho sebelisoa viscometer, e lekanyang ho hanyetsa ha mokelikeli ho phalla. Mefuta e fapaneng ea li-viscometer e ka sebelisoa, ho kenyeletsoa li-viscometer tse potolohang le li-viscometer tsa capillary, ho latela ts'ebeliso e itseng le mefuta e fapaneng ea viscometer e khahlisang.

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

Indastering ea kaho, HEC e sebelisoa e le sesebelisoa sa ho teteana le ho boloka metsi lihlahisoa tse thehiloeng samenteng, tse kang li-mortar, grout le konkreite. Ho teteana ha HEC lits'ebetsong tsena ho bohlokoa bakeng sa ho fihlela bokhoni bo lakatsehang ba ho sebetsa, ho khomarela le ho tsitsa ha sehlahisoa sa ho qetela.

Ho teteana ha HEC ho ka boela ha fetoloa ka mekhoa e fapaneng ea lik'hemik'hale le ea 'mele, ho kenyeletsoa ho kopanya, ho hydrolysis ea asiti, le ho kopanya le li-polymer tse ling. Liphetoho tsena li ka fetola litšobotsi tsa HEC 'me tsa fella ka ts'ebetso e ntlafetseng lits'ebetsong tse itseng.

Ka bokhutšoanyane, ho teteana ha HEC ke ntlha ea bohlokoa ho khetholleng ts'ebetso ea eona lits'ebetsong tse fapaneng. Tekanyo ea phetoho, boima ba limolek'hule, mahloriso le pH kaofela li bapala karolo ho khetholleng ho teteana ha eona, e leng se ka lekanngoang ho sebelisoa viscometer. Liindasteri le lits'ebetso tse fapaneng li ka hloka maemo a fapaneng a ho teteana, 'me liphetoho ho HEC li ka etsoa ho ntlafatsa ts'ebetso ea eona lits'ebetsong tse itseng.
