The function and application of 2507 Capillary tube
1. The general trend of 2507 Capillary tube is to help the transfer of pigment molecules to the oil phase. As long as the pigment particles have a certain lipophilicity, under the action of stirring, the oil phase will spontaneously wet the surface of the aggregated particles and make them Gradually disintegrate in the oil phase, eventually allowing the oil to enter the interior of the pigment particles and expel the water. A small amount of moisture remaining inside the particles can also be separated by heating under vacuum.
2. 2507 Capillary tube is widely used. 2507 Capillary tube function can be used for plastic bonding and metal brazing. Groundwater in the field flows through the pores of the soil (equivalent to a 2507 Capillary tube) to the roots of the plants. The working principle of the ink absorber is also the function of 2507 Capillary tube. The towel has an infinite number of 2507 Capillary tubes, so it can dry water from the skin. The sponge draws water into its 2507 Capillary tube.
3. The function of 2507 Capillary tube: Because the undried water-based pigment filter cake has a complex microstructure, when the pigment particles are surrounded by the oil phase, the contact angle is less than 90°, and the wetting effect can occur. At this time, the pore size of the 2507 Capillary tube inside the particle is related to the pressure difference of the 2507 Capillary tube. The thinner the 2507 Capillary tube, the greater the infiltration force of the solvent. However, due to the unevenness and poor regularity of the 2507 Capillary tube, the infiltration rates of the particles in different regions of the oil phase are different, so that the water is surrounded by the oil before it is completely replaced by the oil, so that a small amount of water cannot be completely replaced. remains inside the particle.
