Menene bambanci tsakanin HEC da CMC?

HEC da CMC nau'i biyu ne na ether cellulose, polysaccharide wanda ake samu a cikin tsire-tsire kuma ana amfani dashi a cikin nau'o'in samfurori.Duk da yake duka biyu an samo su daga cellulose, suna da kaddarorin kaddarorin da aikace-aikace.

HEC, ko hydroxyethyl cellulose, ba ionic ba ne, polymer mai narkewa da ruwa wanda aka samu daga cellulose.Ana amfani da shi azaman wakili mai kauri, emulsifier, stabilizer, da wakili mai dakatarwa a cikin samfura iri-iri, gami da kayan kwalliya, magunguna, da samfuran abinci.Har ila yau, ana amfani da HEC don ƙara danko na maganin ruwa da kuma inganta yanayin samfurori.Ana kuma amfani da ita wajen samar da takarda, fenti, da manne.

CMC, ko carboxymethyl cellulose, shine polymer mai narkewa da ruwa wanda aka samu daga cellulose.Ana amfani da shi azaman wakili mai kauri, emulsifier, stabilizer, da wakili mai dakatarwa a cikin samfura iri-iri, gami da kayan kwalliya, magunguna, da samfuran abinci.Hakanan ana amfani da CMC don ƙara ɗanɗanowar hanyoyin ruwa da inganta yanayin samfuran.Ana kuma amfani da ita wajen samar da takarda, fenti, da manne.

Babban bambanci tsakanin HEC da CMC shine a tsarin sinadarai.HEC polymer ba na ionic ba ne, ma'ana cewa ba shi da wani cajin da ke tattare da shi.CMC, a gefe guda, shine polymer ionic, ma'ana yana da mummunan cajin da ke tattare da shi.Wannan bambance-bambance a cikin caji yana rinjayar hanyar da polymers biyu ke hulɗa tare da wasu kwayoyin halitta, don haka yana rinjayar kaddarorin su da aikace-aikace.

HEC ya fi narke cikin ruwa fiye da CMC, kuma ya fi tasiri a matsayin wakili mai kauri.Har ila yau, ya fi kwanciyar hankali a cikin maganin acidic da alkaline, kuma ya fi tsayayya da zafi da haske.HEC kuma ya fi juriya ga lalata ƙwayoyin cuta, yana mai da shi mafi kyawun zaɓi don samfuran da ke buƙatar rayuwa mai tsayi.
