Particle Size on Adhesive Force in Liquid Media

Influence of Particle Size on Adhesive Force in Liquid Media 

Dependence of Adhesive Force on Particle Size in Detachment by Inclination of Surface. Detachment of particles by tilting the surface (see Section 11) has been used to investigate the adhesion of quartz particles of various sizes in an aqueous medium [4] and also in certain organic solvents and alcohols [190, 197]. 

The adhesion of a particle layer, as determined by the surface inclination technique in certain organic solvents, was found to be as follows [190]  

Under these conditions, the adhesive force of the particle layer is roughly proportional to the particle size. A similar relationship between adhesive force and the size of quartz particles was observed [190] in certain alcohols. 

In some solvents that are relatively immiscible with water (ethyl acetate, ethyl ether, nitrobenzene, benzene, toluene, carbon tetrachloride, hexane), the value of sin a, which characterizes the angle for particle detachment, decreases monotonically with increasing particle radius r and is determined in accordance with the following formula [197]
