翡翠弧形戒面的抛光工艺

Polishing Process of Jadeite Cabochon

翡翠是一种深受人们喜爱的玉石,其戒面的市场需求量很大。但市场上翡翠戒面的抛光质量参差不齐,且与翡翠戒面抛光工艺相关的资料十分有限。通过分别控制细豆种翡翠的粗抛方式(砂纸、油石的选择)、精抛方式(抛光盘、抛光剂的选择),对翡翠戒面抛光工艺进行了研究,运用得到的最佳抛光工艺参数对各种质地翡翠进行抛光验证。结果表明:对翡翠弧形戒面进行粗抛时,选用600、1000、1500目砂纸盘的组合抛光效果最好;精抛时抛光粉选用W2.5、W1.5抛光盘,钻石粉、牛皮盘(或羊毛毡盘)的组合抛光效果最好;各种质地的翡翠戒面经此法粗抛光、精抛光后均能得到良好的抛光效果。

Jadeite jade is a very popular jade in China and the demand for ornaments of jadeite is great. However, the polishing qualities of the jadeite cabochons vary unevenly on the market and there is little published literature on the polishing process of jadeite cabochons. In this study, an experiment on jadeite cabochon polishing was carried out according to fast polishing method (choose of sandpaper or oil-stone) and fine polishing method (choose of polishing lap and abrasive). The final process parameters were used to verify in the process of jadeite jade with all kinds of texture. It was proved that a sandpaper combo of 600, 1 000, 1 500 grit leads to the best result in fast polishing process, so as to a diamond paste combo of 2.5, 1.5-micron, cowhide (or wool) polishing lap in fine polishing process. According to that polishing process, jadeite cabochons in all kinds of textures will show high gloss.
