1 前言 颗粒是物质的分散状态存在,粒度范围可以从几米至胶体(0.01微米)。可按分散剂的不同加以分类。例: 当分散剂是气体时,可有气——气混合物(粒度为10~(-10)～10~(-8)m)、气——液混合物(如雾,粒度为10~(-8)～10(-5)m,称悬浮体)、组成气——固混合物(如烟,粒度为10~(-8)～10~(-5)m,也称悬浮体)。 当分散剂是液体时,可有泡沫体系(粒度
1 Introduction Particles are a dispersed state of matter that can range in particle size from a few meters to colloids (0.01 microns). According to the different dispersants to be classified. Example: When the dispersant is a gas, a gas-gas mixture (particle size of 10 -10 to 10 -8 m), a gas-liquid mixture ) ~ 10 (-5) m, said the suspension), composition gas - solid mixture (such as smoke, particle size 10 ~ (-8) ~ 10 ~ (-5) m, also known as suspension). When the dispersant is a liquid, there may be a foam system (particle size
