The relationship between oil absorption and dispersion of other dispersive pigments

unevenly dispersed (large particle size) pigments, the amount of oil absorption depends on the pigment's absorption capacitySome pigments (e.giron red) their particles are adsorbed to the liquid shell wrapped up, the particles do not come into direct contact with each other, but adsorption of the liquid shell contactThese shells are filled with gaps between the particles, and they cannot be placed between the grainsSuch unevenly dispersed pigments, their mixture of oil absorption, can be calculated by the mix of pigments individual components of the oil absorption and contentSome pigment particles do notWith adsorption liquid rest of the shell, between the coarse particles, particle size difference is large, fine particles will be inserted between the coarse particlesThese pigments, such as chromium oxide, green, their mixed faceThe amount of oil absorbed by the material is not related to the addition, nor can it be calculatedpigment siphons of oil absorption although one and dispersiveClose relationship, the cane is not a separate decision of dispersionAfter the moisture content in the synthetic pigment is listed to a certain extent, the oil absorption will decrease with the increase of the water content
