Melemo ea hydroxyethylcellulose ke efe?

Hydroxyethylcellulose (HEC) ke polima e qhibilihang ka metsing e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa litlolo, lihlahisoa tsa tlhokomelo ea motho, le meriana. E tsoa ho selulose ka ho eketsoa ha lihlopha tsa hydroxyethyl mokokotlong oa cellulose. HEC e na le melemo e 'maloa liindastering tsena, ho kenyelletsa le thepa ea eona e teteaneng le ea gelling, bokhoni ba eona ba ho matlafatsa botsitso ba li-emulsion, le ho lumellana ha eona le mefuta e mengata ea lisebelisoa tse ling.

Thickening le Gelling Thepa

E 'ngoe ea melemo ea mantlha ea HEC ke bokhoni ba eona ba ho tenya le ho kenya litharollo tse nang le metsi. HEC e na le boima bo phahameng ba limolek'hule le tekanyo e phahameng ea ho fetola, e lumellang hore e thehe maqhama a matla a hydrogen le limolek'hule tsa metsi. Thepa ena e e etsa hore e be sesebelisoa se matla sa ho nona lits'ebetsong tse fapaneng tse fapaneng, ho kenyelletsa li-shampoo, li-conditioner, lotions le li-gel.

Ka lihlahisoa tsa tlhokomelo ea botho, HEC e atisa ho sebelisoa ho fana ka mokhoa o boreleli le o monate, ho eketsa viscosity ea sehlahisoa, le ho ntlafatsa botsitso ba eona. E ka boela ea ntlafatsa ho hasana le boiketlo ba tšebeliso ea lihlahisoa, ho etsa hore e be bonolo ho basebelisi. HEC ke motsoako o nang le mekhoa e mengata e ka sebelisoang mefuteng e mengata ea tlhokomelo ea botho, ho kenyelletsa tlhokomelo ea moriri, tlhokomelo ea letlalo le lihlahisoa tsa tlhokomelo ea molomo.

Indastering ea meriana, HEC e sebelisoa e le ntho e matlafatsang mefuteng e sa tšoaneng, ho akarelletsa le li-gel, litlolo le litlolo. E ka boela ea sebelisoa ho fetola thepa ea rheological ea suspensions le emulsions. HEC e ka ntlafatsa botsitso le homogeneity ea metsoako ena, ho etsa hore ho be bonolo ho sebetsana le eona le ho atleha haholoanyane.

Ntlafatso ea botsitso ba Emulsion

HEC e boetse e tsejoa ka bokhoni ba eona ba ho ntlafatsa botsitso ba li-emulsions. Emulsion ke motsoako oa li-immiscible liquids tse peli, tse kang oli le metsi, tse tsitsitseng ke moemeli oa emulsifying. HEC e ka sebetsa e le emulsifier, e etsa sebopeho se tsitsitseng pakeng tsa mekhahlelo ea oli le metsi. E ka boela ea ntlafatsa thepa ea rheological ea emulsions, e etsa hore ho be bonolo ho sebetsana le eona le ho tsitsa ha nako.

Lefapheng la litlolo, HEC e atisa ho sebelisoa ka li-emulsion tse kang litlolo le litlolo ho ntlafatsa botsitso ba tsona, viscosity le mokhoa oa ho etsa lintho. E ka boela ea ntlafatsa ho hasana le boiketlo ba tšebeliso ea lihlahisoa tsena. HEC e ka sebelisoa mefuteng e mengata ea tlhokomelo ea botho, ho akarelletsa le li-moisturizers, li-sunscreens, le litlolo.

Ho lumellana le Lisebelisoa tse ling

Molemo o mong oa HEC ke ho lumellana ha eona le mefuta e mengata ea lisebelisoa tse ling. HEC ke polymer ea nonionic e se nang tefiso ea motlakase, e etsang hore e se ke ea tloaelana le limolek'hule tse ling tse qosoang. Thepa ena e lumella hore e sebelisoe le mefuta e mengata ea lisebelisoa tse ling ntle le ho baka mathata a sa lumellaneng.

HEC e lumellana le mefuta e mengata e mengata ea li-polymers, li-surfactants, le metsoako e sebetsang, e leng se etsang hore e be motsoako o nang le mefuta e mengata mekhoeng e sa tšoaneng. E ka boela ea ntlafatsa ho lumellana le botsitso ba lisebelisoa tse ling, ho etsa hore li atlehe haholoanyane 'me ho be bonolo ho sebetsana le tsona.

Melemo e Meng e ka Khonehang

HEC e na le melemo e meng e mengata, ho latela kopo. Ka mohlala, HEC e ka sebetsa e le moemeli oa ho etsa filimi, ea theha mokoallo letlalong kapa moriri o ka fanang ka tšireletso kapa oa ntlafatsa ponahalo. HEC e ka boela ea sebetsa e le moemeli ea emisang, e thibelang likaroloana hore li se ke tsa lula ho ea tlaase ho sebopeho. Thepa ena e ka ntlafatsa homogeneity le botsitso ba sebopeho, ho etsa hore ho be bonolo ho sebetsana le ho sebetsa hantle.

Lefapheng la meriana, HEC e bontšitsoe hore e na le melemo ea phekolo ea ho folisa maqeba, ho fana ka lithethefatsi le boenjiniere ba lisele. HEC e ka sebetsa e le matrix bakeng sa ho fana ka lithethefatsi, ho lokolla motsoako o sebetsang ka nako ho finyella phello e tsitsitseng ea phekolo.
