WitrynaAs lignin surfactants contain hydrophilic groups, when it is dispersed in the discrete-phase coal particles, it can weaken the hydrophobic interaction of the surface on coal particles and form a layer of hydration film on the surface. The hydration film exerts a lubrication effect, decreasing the friction between the particles. WitrynaA hydrophilic colloid, or hydrocolloid, is defined as a colloid system in which the colloid particles are hydrophilic polymers dispersed in water. Hydrocolloids can be either reversible or irreversible (single-state). For example, agar is a reversible hydrocolloid of seaweed extract; it can exist in a gel or liquid state and can alternate ...
