求翻译：当分散剂与颗粒发生吸附时，将会形成一层保护膜包覆在颗粒表面，使颗粒间质心距离增大，如上所述，这将会使得颗粒间的范德瓦耳斯引力作用减小。是什么意思？

When the dispersant and particulate adsorption occurs, will form a protective film coated on the particle surfaces, so that the centroid distance between the particles is increased, as described above, which will make the gravitational effect of the particles between the Van der Waals reduced .

When a particle dispersion, adsorption will be formed when a layer of protection film kit by particles in the particle-surface quality and distance, as mentioned above, this will make the van between the granules, ear, gravitational effect will decrease.

When the dispersing agent and the pellet has the adsorption, will be able to form a protective film gable in the pellet surface, will cause the intergranular center of mass distance to increase, as stated above, this will be able to cause the intergranular Vander the tile ear Si gravitation will red

When a dispersant is particle adsorption occurs, will form a layer of protective film coated on particle surface to enable centroid distance between particles increases, as mentioned above, this will allow the van der Waals attraction between particles decreases.
