黄铜拉链仿金牙抛光工艺
|
摘要
讨论了前处理、抛光液配方、温度、时间等因素对H65黄铜拉链抛光效果的影响,确定了仿金牙色的最佳抛光工艺为:过氧化氢600~750 mL/L,硫酸8~15 mL/L,增亮剂3~5 mL/L,乙醇60~90 mL/L,脂肪醇聚氧乙烯醚(AEO-9)0.4~0.8 g/L,温度20~30℃,时间2~3 min。该工艺抛光的黄铜拉链牙色光亮均匀,达到18K金的效果,而且抛光液稳定,使用寿命长,操作简单,维护方便,污染小。该工艺也适用于其他H65黄铜制品的仿金抛光。
The effects of pretreatment, polishing bath composition, temperature and time on polishing effectiveness of H65 brass zipper were discussed. The optimal polishing process conditions for gold-imitation teeth effect were obtained as follows: hydrogen peroxide 600-750 mL/L, sulfuric acid 8-15 mL/L, brightening agent 3-5 mL/L, ethanol 60-90 mL/L, fatty alcohol polyoxyethylene ether(AEO-9) 0.4-0.8g/L, temperature 20-30 ℃ and time 2-3 min. The brass zipper teeth color obtained thereunder is bright and uniform, achieving the effect of 18 K gold. The polishing bath features high stability, long service life, simple operation, easy maintenance and less pollution. The process is applicable to polishing of other H65 brass products.
