colloidal gel การใช้

• However, colloidal suspensions of higher-volume fraction form colloidal gels with viscoelastic properties.
• The fully dissolved mixture is then refrigerated, slowly forming a colloidal gel as it cools.
• Usually, you can't freeze anything that is a colloid, or a colloidal gel.
• Viscoelastic colloidal gels, such as bentonite and toothpaste, flow like liquids under shear, but maintain their shape when shear is removed.
• For example, larger primary particles may settle even in the absence of aggregation, or aggregates that have formed a colloidal gel will remain in suspension.
