Menene bambanci tsakanin HEC da MHEC?

HEC da MHEC nau'ikan nau'ikan nau'ikan nau'ikan polymers ne na cellulose waɗanda ake amfani da su a cikin aikace-aikace iri-iri, gami da masu kauri, masu daidaitawa, da emulsifiers a cikin samfuran abinci, da kuma samfuran magunguna da kayan kwalliya. Babban bambanci tsakanin su biyu shine HEC shine hydroxyethyl cellulose, yayin da MHEC shine methyl hydroxyethyl cellulose.

HEC polymer ce mai narkewa da ruwa wanda aka samo daga cellulose, polysaccharide da ke faruwa ta halitta wanda aka samu a cikin tsire-tsire. Ya ƙunshi jerin gwanon ƙwayoyin glucose na linzamin kwamfuta tare da ƙungiyar hydroxyethyl da ke haɗe zuwa ƙarshen kowane kwayar halitta. Ana amfani da HEC cellulose azaman mai kauri, mai ƙarfi, da emulsifier a cikin samfuran abinci, da kuma a cikin samfuran magunguna da kayan kwalliya. Ana kuma amfani da ita wajen yin takarda da bugu, da kuma wajen kera manne da sutura.

MHEC wani nau'i ne na HEC cellulose da aka gyara wanda aka maye gurbin ƙungiyar hydroxyethyl tare da ƙungiyar methyl. Wannan gyare-gyare yana ƙara yawan hydrophobicity na polymer, yana sa ya fi tsayayya ga abubuwa masu narkewa da ruwa. Ana amfani da MHEC a cikin aikace-aikace iri-iri, gami da a matsayin mai kauri, stabilizer, da emulsifier a cikin samfuran abinci, da kuma a cikin samfuran magunguna da kayan kwalliya. Ana kuma amfani da ita wajen yin takarda da bugu, da kuma wajen kera manne da sutura.

A taƙaice, babban bambanci tsakanin HEC cellulose da MHEC shine HEC shine hydroxyethyl cellulose, yayin da MHEC shine methyl hydroxyethyl cellulose. Dukansu kayan ana amfani da su a cikin nau'ikan aikace-aikace, ciki har da masu kauri, stabilizers, da emulsifiers a cikin samfuran abinci, da kuma a cikin samfuran magunguna da kayan kwalliya.
