Phapano ke efe lipakeng tsa HPMC le HEMC?

HPMC (Hydroxypropyl Methylcellulose) le HEMC (Hydroxyethyl Methylcellulose) ka bobeli ke lintho tse nkiloeng ho cellulose tse sebelisoang e le li-thickeners, binders, le emulsifiers lihlahisoa tse fapaneng. Ka bobeli li tsoa ho cellulose, polysaccharide ea tlhaho e fumanoang limela.

Phapang e kholo pakeng tsa HPMC le HEMC ke mofuta oa lihlopha tsa hydroxypropyl le hydroxyethyl tse khomaretsoeng molek'hule ea cellulose. HPMC e na le lihlopha tsa hydroxypropyl tse khomaretsoeng molek'hule ea cellulose, ha HEMC e na le lihlopha tsa hydroxyethyl tse khomaretsoeng. Phapang ena mofuteng oa lihlopha tsa hydroxypropyl le hydroxyethyl e ama thepa ea lintho tse tsoang ho tse peli tsa cellulose.

HPMC e qhibiliha haholoanyane metsing a batang ho feta HEMC, 'me e hanyetsana le liphetoho tsa mocheso. E na le viscosity e phahameng ho feta HEMC, 'me e hanyetsa ho feta acid le alkali. E boetse e hanyetsana le ho senyeha ha likokoana-hloko. HPMC e sebelisoa lihlahisoa tse fapaneng, ho kenyeletsoa lijo, meriana le litlolo.

HEMC ha e qhibilihe ka metsing a batang ho feta HPMC, 'me ha e hanyetsane le liphetoho tsa mocheso. E na le viscosity e tlase ho feta HPMC, 'me ha e hanyetsane le asiti le alkali. Hape ha e hanyetsane le ho senyeha ha likokoana-hloko. HEMC e sebelisoa lihlahisoa tse fapaneng, ho kenyeletsoa lijo, meriana, le litlolo.

Ka kakaretso, HPMC le HEMC ka bobeli ke lintho tse nkiloeng ho cellulose tse sebelisoang e le li-thickeners, binders, le emulsifiers lihlahisoa tse fapaneng. Phapang e kholo lipakeng tsa tse peli ke mofuta oa lihlopha tsa hydroxypropyl le hydroxyethyl tse khomaretsoeng molek'hule ea cellulose. HPMC e na le lihlopha tsa hydroxypropyl tse khomaretsoeng molek'hule ea cellulose, ha HEMC e na le lihlopha tsa hydroxyethyl tse khomaretsoeng. Phapang ena mofuteng oa lihlopha tsa hydroxypropyl le hydroxyethyl e ama thepa ea lintho tse tsoang ho tse peli tsa cellulose.
