Aikace-aikace da shirye-shiryen hydroxyethyl methyl selululose hemc

Hydroxyethyl methyl selululose hemcZa a iya amfani da shi azaman wakili mai kariya na Colloid, emulsifier da watsawa saboda farjin aikinta a cikin mafita. An example of its application is as follows: The effect of hydroxyethyl methyl cellulose on the properties of cement. Hydroxyethyl methylcellulose wani kamshin ƙanshi ne, mai ƙanshi da farin foda wanda ke narkewa a cikin ruwan sanyi don samar da bayyananne, maganin viscous. Yana da kaddarorin thickening, ɗauri, watsawa, emulsify, emping, m, m, farfajiya-aiki, riƙe danshi da kare colloids. Saboda farfajiya mai aiki na farfajiya na mafita mafi kyau, ana iya amfani dashi azaman wakili mai kariya na Colloid, wanda emulsifier da watsawa. Hydroxyethyl metyl selululue bayani yana da kyau hydrophility kuma shine wakili mai amfani da ruwa mai amfani da ruwa.
