要使有色金属件达到▽▽▽▽11～▽▽▽▽13的表面光洁度要求,过去我们是采用兰宝石粉抛光膏或油酸氧化铬(Cr_2O_3)抛光膏抛光。使用这两种抛光膏,效果虽然都比较好,但是它们都含有较多的油酸,价格贵,也不容易买到。同时兰宝石粉焙烧也很麻烦。针对以上情况,我们试制成功了猪油氧化铬抛光膏,通过生产验证,应用这种抛光膏完全可以满足加工要求。 To make the non-ferrous metal parts ▽ ▽ ▽ ▽ 11 ~ ▽ ▽ ▽ ▽ 13 surface finish requirements, in the past we are polished with sapphire powder or chromium oxide oleate (Cr 2 O 3) polishing paste. The use of these two kinds of polishing paste, although the effect is better, but they all contain more oleic acid, expensive, not easy to buy. At the same time sapphire powder roasting is also very troublesome. In view of the above, we successfully trial lard chromium oxide polishing paste, through the production verification, the application of this polishing paste can fully meet the processing requirements.
