Abstract:The distribution characters of air bubbles in the coatings was analyzed. The effects of sieving by using screens with different meshes and arrangements on deaeration were studied. Large-scale trials were carried out in the mill. Results showed that the deaeration efficiency was the best when sieving with screens arrangement of 325 mesh-400 mesh-400 mesh. The results using mill’s vibration screen were similar to that using laboratory vibration screen. But the treatment rate was higher for mill’s vibration screen.
