You may not know these functions of 2507 Capillary tube products
Due to the complex microstructure of the undried water-based pigment filter cake, wetting can occur when the pigment particles are surrounded by the oil phase with a contact angle of less than 90°. At this time, the pore diameter of the 2507 Capillary tube products inside the particles is related to the pressure difference of the 2507 Capillary tube products. The finer the 2507 Capillary tube products, the greater the wetting force of the solvent. However, due to the unevenness and irregularity of 2507 Capillary tube products, the permeability of the particles in different regions of the oil phase is different, so that the water is surrounded by the oil before it is completely replaced by the oil, resulting in a small amount of water that cannot be completely replaced and remains inside the particles.
But the general trend of 2507 Capillary tube products is to help the pigment molecules transfer to the oil phase. As long as the pigment particles have a certain degree of lipophilicity, under the action of stirring, the oil phase will spontaneously wet the surface of the aggregated particles, and gradually disintegrate in the oil phase, and finally the oil enters the pigment particles and the water discharges. Small amounts of water remaining inside the particles can also be separated by heating under vacuum.
