Nga ahuatanga o te konutai Carboxymethyl Cellulose
Ko te CMC he huanga cellulose me te tohu polymerization glucose o 200-500 me te tohu etherification o 0.6-0.7.He paura ma, he ma, he matū kiriu ranei, he hongi me te hygroscopic.Ko te tohu o te whakakapinga o te roopu carboxyl (te tohu o te etherification) e whakatau ana i ona ahuatanga.I te mea kei runga ake i te 0.3 te tohu etherification, ka whakarewahia i roto i te wairewa alkali.Ko te viscosity o te wairewa wai ka whakatauhia e te pH me te tohu o te polymerization.I te wa e 0.5-0.8 te tohu o te etherification, e kore e rere ki roto i te waikawa.Ko te CMC he ngawari ki te wairewa i roto i te wai, ka noho hei wairewa puataata ki roto i te wai, a ka rereke tona pokey ki te kukū o te otinga me te pāmahana.He pūmau te pāmahana i raro i te 60°C, ka heke te pokey ina whakamahana mo te wa roa i te pāmahana i runga ake i te 80°C.
Te whānuitanga o te whakamahinga o te konutai carboxymethyl cellulose
He maha nga mahi penei i te whakapakeke, te whakatarewa, te whakaemulsifying me te whakapumau.I roto i te hanga inu, ka whakamahia te nuinga hei whakakaha mo nga inu wai momo penupenu, hei whakapumau emulsification mo nga inu pūmua me te whakapumau mo nga inu miraka.Ko te tikanga ko te 0.1% -0.5%.
