Aikace-aikace da shirye-shiryen hydroxyethyl methyl selululose hemc

Ana iya amfani da Hydroxyethyl Selell Cellululose Hemc a matsayin wakili mai kare na Colloid, emulsifier da watsawa saboda a cikin aikinsa mai aiki 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.
