When different engraving or polishing processes are applied to Ordinary cloud pumice gold plated, it will have many effects on the gold layer.
First, the engraving process. If fine bas-relief engraving is used to carve exquisite patterns on the surface of cloud pumice, when gold plating is performed, the gold layer will have different adhesion conditions on the concave and convex parts of the engraving. On the convex part, the gold layer is relatively easier to cover evenly, showing a bright and continuous golden luster, which can well highlight the outline and three-dimensional sense of the pattern. However, in the concave part, due to the possible existence of air residue or the difficulty of sufficient infiltration of the gold plating solution, the gold layer may be relatively thin or uneven. If the engraving depth is large, special measures may be needed in the subsequent gold plating process to ensure that the concave part can also have a good gold plating effect, such as adjusting the concentration of the gold plating solution or using multiple gold plating methods.
In terms of polishing technology, the coarseness of polishing has a significant impact on the gold layer. If it is rough grinding, although the rough part of the surface of Yunfu stone can be quickly removed, it may cause the surface to be too rough, affecting the flatness and glossiness of the gold layer. When the gold layer is covered, the surface of the gold layer may be rough and granular, affecting the overall beauty. The surface of Yunfu stone after fine grinding is smoother, and the gold layer can be evenly and tightly attached, showing a mirror-like gloss, and the visual effect is better. However, excessive grinding may also be risky. For example, it may make the surface of Yunfu stone too smooth, making it difficult for the gold plating solution to adhere, and a special surface treatment agent is needed to improve the adhesion of the gold layer.
In addition, whether it is engraving or polishing process, the order is also very important. If gold plating is performed first and then engraving, the integrity of the gold layer may be destroyed, causing the gold layer on the edge of the engraving to peel off or burr. Engraving first and then gold plating requires precise control of the engraving process to ensure that the gold layer can cover the entire engraving surface well during gold plating. In short, the reasonable selection and application of engraving and polishing processes are crucial to the final effect of Yunfu stone gold plating.
