Abstract

As a result of studying the laws of interaction of sludge particles and polishing powder wear particles during polishing of polystyrene, polymethyl methacrylate, and polyallyldiglycocarbonate with use of dispersed micro- and nanopowder systems, it is found that the total number of sludge nanoparticles and wear powder nanoparticles of tools exceeds the number of polishing powder particles and the total volume of the former is much smaller than the volume of the contact zone. It is shown that the scattering of sludge particles on the wear particles of the polishing powder occurs at angles of 90° to 160°. The effective differential cross section of nanoparticle scattering is in the range of 0.3–4.4 Tb. The maximum value of the scattering angle and the minimum value of the effective differential scattering cross section, which are observed when polishing polystyrene using a dispersed system based on cerium dioxide, indicate the highest probability of plaque formation from nanoparticles of wear polishing powder on the treated surface.

聚合物光学材料抛光过程中抛光粉中污泥颗粒与磨损颗粒的相互作用

利用分散的微粉和纳米粉体系，研究了聚苯乙烯、聚甲基丙烯酸甲酯和聚烯基二乙酸酯在抛光过程中污泥颗粒和抛光粉磨损颗粒的相互作用规律，发现工具中污泥纳米颗粒和磨损粉纳米颗粒的总数超过了抛光粉颗粒的数量，而前者的总体积远远小于接触区体积。结果表明，污泥颗粒在抛光粉磨损颗粒上的散射发生在90°~ 160°的角度上。纳米粒子散射的有效微分截面在0.3 ~ 4.4 Tb之间。用二氧化铈分散体系抛光聚苯乙烯时，散射角的最大值和有效微分散射截面的最小值表明，磨损抛光粉的纳米颗粒在处理表面形成斑块的可能性最大。
