Kodi pali kusiyana kotani pakati pa HEC ndi CMC?

HEC ndi CMC ndi mitundu iwiri ya cellulose ether, polysaccharide yomwe imapezeka muzomera ndipo imagwiritsidwa ntchito pazinthu zosiyanasiyana.Ngakhale onsewa amachokera ku cellulose, ali ndi katundu wosiyana komanso ntchito zake.

HEC, kapena hydroxyethyl cellulose, ndi polima yopanda ionic, yosungunuka m'madzi yochokera ku cellulose.Amagwiritsidwa ntchito ngati thickening agent, emulsifier, stabilizer, ndi kuyimitsa wothandizira pazinthu zosiyanasiyana, kuphatikizapo zodzoladzola, mankhwala, ndi zakudya.HEC imagwiritsidwanso ntchito kuonjezera kukhuthala kwa mayankho amadzimadzi komanso kukonza kapangidwe kazinthu.Amagwiritsidwanso ntchito popanga mapepala, utoto, ndi zomatira.

CMC, kapena carboxymethyl cellulose, ndi polima wosungunuka m'madzi wotengedwa ku cellulose.Amagwiritsidwa ntchito ngati thickening agent, emulsifier, stabilizer, ndi kuyimitsa wothandizira pazinthu zosiyanasiyana, kuphatikizapo zodzoladzola, mankhwala, ndi zakudya.CMC imagwiritsidwanso ntchito kuonjezera mamasukidwe amadzimadzi amadzimadzi komanso kuwongolera kapangidwe kazinthu.Amagwiritsidwanso ntchito popanga mapepala, utoto, ndi zomatira.

Kusiyana kwakukulu pakati pa HEC ndi CMC kuli mu kapangidwe kake ka mankhwala.HEC ndi polima yopanda ionic, kutanthauza kuti ilibe milandu yokhudzana nayo.CMC, kumbali ina, ndi polima ionic, kutanthauza kuti ili ndi mlandu woyipa wokhudzana nawo.Kusiyana kumeneku kumakhudza momwe ma polima awiriwa amalumikizirana ndi mamolekyu ena, motero amakhudza katundu wawo ndi ntchito zawo.

HEC imasungunuka kwambiri m'madzi kuposa CMC, ndipo imakhala yothandiza kwambiri ngati chowonjezera.Imakhalanso yokhazikika muzitsulo za acidic ndi zamchere, ndipo imagonjetsedwa kwambiri ndi kutentha ndi kuwala.HEC imalimbananso kwambiri ndi kuwonongeka kwa tizilombo toyambitsa matenda, ndikupangitsa kuti ikhale yabwino kwa zinthu zomwe zimafuna moyo wautali wautali.

CMC imasungunuka pang'ono m'madzi kuposa HEC, ndipo sigwira ntchito ngati thickening agent.Imakhalanso yosakhazikika muzitsulo za acidic ndi zamchere, ndipo imagonjetsedwa ndi kutentha ndi kuwala.CMC imakhalanso pachiwopsezo cha kuwonongeka kwa tizilombo tating'onoting'ono, ndikupangitsa kuti ikhale chisankho choyenera pazinthu zomwe zimafunikira nthawi yayitali.

Pomaliza, HEC ndi CMC ndi mitundu iwiri ya cellulose ether yokhala ndi katundu wosiyana ndi ntchito.HEC imasungunuka kwambiri m'madzi ndipo imakhala yogwira ntchito ngati thickening agent, pamene CMC imakhala yochepa kwambiri m'madzi ndipo imakhala yochepa kwambiri ngati yowonjezera.HEC imakhalanso yokhazikika muzitsulo za acidic ndi alkaline, ndipo imagonjetsedwa kwambiri ndi kutentha ndi kuwala.CMC ndi yosakhazikika muzitsulo za acidic ndi zamchere, ndipo imagonjetsedwa ndi kutentha ndi kuwala.Ma polima onsewa ali ndi ntchito zosiyanasiyana popanga zodzoladzola, mankhwala, zakudya, mapepala, utoto, ndi zomatira.
