Embodiment
[0049] Embodiment, a kind of copper workpiece surface thermal coloring method, such as figure 1 As shown, in this embodiment, the surface thermal coloring of the manganese bronze handle 1 with higher hardness is taken as an example.
[0050] Such as figure 2 As shown, the surface heat coloring method of manganese bronze handle 1 includes:
[0051] Step 1, workpiece surface grinding treatment;
[0052] 1.1 Sandblasting the workpiece, put the manganese bronze handle 1 into the sandblasting machine and use 150 mesh quartz sand for surface sandblasting.
[0053] Specifically, sandblasting is carried out uniformly according to the shape of the handle during sandblasting. In addition, an appropriate spraying distance and angle between the spray gun and the manganese bronze handle 1 must be maintained. The oxide film on the surface of the bronze handle 1; in this embodiment, the sandblasting pressure is 6kg / cm², and the spraying distance is 5-8cm.
[0054] 1.2 Air gun sand clean...

The invention discloses a method for thermally coloring the surface of a copper workpiece. The key points of the technical scheme include: step 1, grinding the surface of the workpiece; step 2, dipping the hanger on the workpiece; In the oil solution; the workpiece is soaked, the hanger is soaked in the dipping solution including basic copper carbonate and ammonia, and then washed with running water; the workpiece is fixed, the hanger is soaked in the fixing solution including copper nitrate , followed by running water cleaning; hot water cleaning, immersing the hanger in hot water of 80-90 degrees; step 3, burning and catalyzing the hanger under the workpiece; step 4, waxing the surface of the workpiece; step 5, wiping the surface of the workpiece . The invention has the effect of shortening the processing time of a single workpiece in the streamlined thermal coloring processing of copper workpieces.
Description
technical field [0001] The present invention relates to metal surface treatment method, more specifically it relates to a kind of copper workpiece surface thermal coloring method. Background technique [0002] Most of the traditional or ancient bronze coloring methods use cold coloring or natural coloring. The method is to put the copper piece outdoors or bury it in the soil, and add some formula to make it slowly change color on the surface. Nowadays chemical coloring with bronze is more common. Bronze chemical coloring (BRONZE PATINA), also known as bronze chemical thermal coloring in China, uses heating as a catalyst to promote a chemical reaction between the compound and the bronze surface, and naturally produces various colors to achieve the effect of decorating the bronze surface. [0003] At present, the surface heat coloring process of bronze is mainly used for coloring the outer surface of bronze sculptures. Therefore, the overall heat coloring time is long, and i...
