1.抛光粉的材料 抛光粉通常由氧化铈、氧化铝、氧化硅、氧化铁、氧化锆、氧化铬等组份组成,不同的材料的硬度不同,在水中的化学性质也不同,因此使用场合各不相同。氧化铝和氧化铬的莫氏硬度为9,氧化铈和氧化锆为7,氧化铁更低。氧化铈与硅酸盐玻璃的化学活性较高,硬度也相当,因此广泛用于玻璃的抛光。
Polishing powder 1 polishing powder usually consists of cerium oxide, aluminum oxide, silicon oxide, iron oxide, zirconium oxide, chromium oxide and other components, different material hardness, different chemical properties in water, so the use of different occasions. Alumina and chromium oxide Mohs hardness of 9, cerium oxide and zirconium oxide is 7, lower iron oxide. Cerium oxide and silicate glass have high chemical activity and hardness, so they are widely used in glass polishing.
2.氧化铈的颗粒度 粒度越大的氧化铈,磨削力越大,越适合于较硬的材料,ZF玻璃应该用偏细的抛光粉。要注意的是,所有的氧化铈的颗粒度都有一个分布问题,平均粒径或中位径D50的大小只决定了抛光速度的快慢,而最大粒径Dmax决定了抛光精度

2 the greater the particle size of cerium oxide, the greater the grinding force, the more suitable for the harder material, ZF glass should be used with fine polishing powder. It should be noted that all the cerium oxide particle size has a distribution problem, the average particle size or the size of the median diameter D50 only determines the speed of the polishing speed, and the maximum particle size of Dmax determines the polishing accuracy

光学冷加工生产操作3 的高低。因此,要得到高精度要求,必须控制抛光粉的最大颗粒。
High and low level of optical cold working 3. Therefore, in order to get high precision, the maximum particle size must be controlled.
3. 抛光粉的硬度 抛光粉的真实硬度与材料有关,如氧化铈的硬度就是莫氏硬度7左右,各种氧化铈都差不多。但不同的氧化铈体给人感觉硬度不同,是因为氧化铈抛光粉通常为团聚体。当然,有的抛光粉中加入氧化铝等较硬的材料,表现出来的磨削率和耐磨性都会提高。
The true hardness and hardness of polishing powder 3 polishing powder, such as cerium oxide hardness is hardness of about 7, all kinds of cerium oxide are similar. However, the different hardness of the cerium oxide is different, because the cerium oxide polishing powder is usually aggregate. Of course, some of the polishing powder added alumina and other hard materials, the performance of the grinding rate and wear resistance will increase.
4. 抛光浆料的浓度 抛光过程中浆料的浓度决定了抛光速度,浓度越大抛光速度越高。使用小颗粒抛光粉时,浆料浓度因适当调低
4 the concentration of slurry in the process of polishing slurry determines the polishing speed. The use of small particles of polishing powder, the appropriate concentration of slurry
