Phapano ke efe lipakeng tsa HEC le MHEC?

HEC le MHEC ke mefuta e 'meli ea lisebelisoa tsa li-polymers tse thehiloeng ho cellulose tse sebelisoang mefuteng e fapaneng ea likopo, ho kenyelletsa le li-thickeners, stabilizers, le emulsifiers lihlahisoa tsa lijo, hammoho le lihlahisoa tsa meriana le tsa litlolo. Phapang e kholo lipakeng tsa tse peli ke hore HEC ke hydroxyethyl cellulose, athe MHEC ke methyl hydroxyethyl cellulose.

HEC ke polima e qhibilihang ka metsing e tsoang ho cellulose, polysaccharide ea tlhaho e fumanehang limela. E entsoe ka ketane e lekanang ea limolek'hule tsa tsoekere tse nang le sehlopha sa hydroxyethyl se khomaretsoeng qetellong ea molek'hule ka 'ngoe. HEC cellulose e sebelisoa e le motenya, stabilizer le emulsifier lihlahisoa tsa lijo, hammoho le lihlahisoa tsa meriana le tsa litlolo. E boetse e sebelisoa ha ho etsoa pampiri le ho hatisa, hammoho le ho etsa likhomaretsi le ho roala.

MHEC ke mofuta o fetotsoeng oa HEC cellulose moo sehlopha sa hydroxyethyl se nkeloang sebaka ke sehlopha sa methyl. Phetoho ena e eketsa hydrophobicity ea polymer, e etsa hore e hanane le lintho tse qhibilihang ka metsing. MHEC e sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa joalo ka motenya, stabilizer le emulsifier lihlahisoa tsa lijo, hammoho le lihlahisoa tsa meriana le tsa litlolo. E boetse e sebelisoa ha ho etsoa pampiri le ho hatisa, hammoho le ho etsa likhomaretsi le ho roala.

Ka kakaretso, phapang e kholo pakeng tsa HEC cellulose le MHEC ke hore HEC ke hydroxyethyl cellulose, athe MHEC ke methyl hydroxyethyl cellulose. Lisebelisoa tsena ka bobeli li sebelisoa lits'ebetsong tse fapaneng, ho kenyelletsa le li-thickeners, stabilizers le emulsifiers lihlahisoa tsa lijo, hammoho le lihlahisoa tsa meriana le tsa litlolo.
