A dispersibility na carboxymethyl cellulose shi ne cewa samfurin za a bazu a cikin ruwa, don haka dispersibility na samfurin ya zama wata hanya ta yin hukunci da aikin.Bari mu ƙara koyo game da shi:
1) Ana ƙara wani adadin ruwa zuwa tsarin watsawa da aka samu, wanda zai iya inganta rarrabuwar ƙwayoyin colloidal a cikin ruwa, kuma wajibi ne a tabbatar da cewa adadin ruwan da aka ƙara ba zai iya narkar da colloid ba.
2) Wajibi ne a watsar da ɓangarorin colloidal a cikin matsakaicin mai ɗaukar ruwa wanda ba shi da kyau a cikin ruwa, wanda ba zai iya narkewa a cikin gels mai narkewa ko kuma ba tare da ruwa ba, amma dole ne ya fi girma daga ƙwayoyin colloidal don a iya tarwatsa su gabaɗaya. .su ne monohydric barasa irin su methanol da ethanol, ethylene glycol, acetone, da dai sauransu.
3) Ya kamata a saka gishiri mai narkewa a ruwa a cikin ruwa mai ɗaukar nauyi, amma gishiri ba zai iya amsawa da colloid ba.Babban aikinsa shi ne hana gel mai narkewa daga ruwa daga samar da manna ko coagulating da hazo lokacin da yake hutawa.Mafi yawan amfani da su shine sodium chloride da sauransu.
4) Wajibi ne don ƙara wakili mai dakatarwa zuwa ruwa mai ɗaukar ruwa don hana abin da ya faru na hazo gel.Babban wakili na dakatarwa zai iya zama glycerin, hydroxypropyl methylcellulose, da dai sauransu. Wakilin dakatarwa ya kamata ya zama mai narkewa a cikin mai ɗaukar ruwa kuma ya dace da colloid.Ga carboxymethyl cellulose, idan glycerol aka yi amfani da suspending wakili, da saba sashi ne game da 3% -10% na ruwa mai dako.
5) A cikin aiwatar da alkalization da etherification, cationic ko nonionic surfactants ya kamata a ƙara, kuma a narkar da shi a cikin mai ɗaukar ruwa don dacewa da colloid.Abubuwan da ake amfani da su na yau da kullun sune lauryl sulfate, glycerin Monoester, propylene glycol fatty acid ester, adadin sa shine kusan 0.05% -5% na ruwa mai ɗaukar hoto.
