Ofmaize components of the increase and decrease the porosity of the surface, this limits the ink on the paper of capillarity . 粘合劑成份的增加，降低了表面的孔隙率，這將限制了油墨在紙張中的毛細作用。
It has high psephicity, low surface strengths, high porosity and intensive capillarity because of the long transport function of the water. 由于黃河水的長距離搬運作用，顆粒磨圓度高、表面強度低； 孔隙率高，毛細作用劇烈。
But they can be more easily separated by sliding one slide over the other, as the forces of adhesion, cohesion, and surface tension and capillarity will be easily overcome. 但二者卻可以通過滑動輕易的克服附著力、內聚力、表面張力、毛細作用而分離開來。
