机械抛光的磨料通常为抛光粉和抛光膏.常用的抛光粉为Al_2O_3、Cr_2O_3,它价格便宜,适用性强.抛光膏一般是人造金刚石为好,抛光效果理想,但价格贵,不适合大专院校的学生实验用.我校长期使用的是Al_2O_3抛光粉,由于学生经验不足,制成悬浮液的稠稀适度和在抛光时倒入量掌握不好,加之悬浮液易使粒度不均,抛光效果也不理想,且浪费大.为了改变抛光粉的使用状况,我们进行了一些探讨.金刚石抛光膏至所以抛光效果好,不仅是金刚石磨料硬度高,尖角锋利,还由于将粉制成膏剂后可以沾嵌在抛光织物上,有
Mechanical polishing abrasive is usually polishing powder and polishing paste. Commonly used polishing powder is Al 2 O 3, Cr 2 O 3, it is cheap, applicability.Plasma is generally synthetic diamond as well, the polishing effect is ideal, but expensive, not suitable for college School students experiment with our long-term use of the Al 2 O 3 polishing powder, due to lack of student experience, made of the suspension of the thin and moderate in the amount of pouring when the control is not good, together with the suspension easy to make uneven size, polishing The effect is not ideal, and a waste of large. In order to change the use of polishing powder, we conducted some discussion. Diamond polishing paste so polishing effect is good, not only diamond abrasive hardness, sharp corners, but also due to the powder into a paste After you can dip in the polishing fabric, there
