CrO_3 100克/升(13.3唡/嗧),H(?)SO_4(比重1.84)2克/升(0.14唡/嗧)加亮处理时浸入此等溶液的时间,因其浓度不同而稍有差别,约为2—30秒。(2)机械的修饰;镉层的机械修饰应用得比较少,因为在做这种修饰工作之前,必须预先把底层金属弄好,以便机械修饰时,镀层不致起泡,而仍保持良好的附着状态。普通大的镀镉物件,可以稍微用力擦刷来打光它。(3)镉层有时用涂漆或油漆来修饰,许多清淡
CrO 3 is slightly different when immersed in these solutions when brightened with 2 g / L (0.14 唡 / 嗧) at 100 g / L (13.3 唡 / 嗧), H ()) SO 4 (specific gravity 1.84) , About 2-30 seconds. (2) mechanical modification; mechanical modification of cadmium layer is relatively small, because before doing this modification work, the underlying metal must be pre-made so that the mechanical modification, the coating will not blister, while still maintaining good adhesion status. Ordinary large cadmium plated objects, you can use a little hard brush to light it. (3) Cadmium layer is sometimes painted or painted to decorate, many light
