物理凝聚力和化学凝聚力在粉尘控制中的作用

摘要

粉尘颗粒间的物理凝聚力和化学凝聚力是促使粉尘凝聚的主作用力，用物理的方法增大颗粒粒径可以达到降尘的目的，同样，用化学方法增大颗粒间的凝聚力也可实现降尘。通过对粉尘颗粒间物理凝聚力和化学凝聚力作用比较分析，可以得到采用化学方法比物理方法降尘效果会更加明显。%In the dust particles,physical cohesion and chemical cohesion is the main force to impel dust condensa-tion. Increasing the particle size with the physical method can achieve the purpose of falling dust,also increasing the cohesion of particles with the chemical method can realize falling dust. Through the physical cohesion and chemical cohesion function comparative analysis,the results show that chemical method will be more obvious than physical methods on dust-controlling effect.
