Description
Technical Field
The invention relates to a spray casting imitation mosaic process, in particular to a preparation method for performing mosaic on the surface of a copper device by using one or more metals, which is different from a gold-silver misplacement process and a black copper silver displacement process.
Background
The metal inlay technology can inlay the metal different from the base on the base to form the pattern with multi-metal color, which can greatly improve the beautiful degree.
At present, the following two processes are mainly adopted in the market for inlaying: 1. the gold and silver error process, which can also be called as "gold and silver error", and "error" word means that gold and silver are painted on bronze ware. The method is divided into two decoration methods, namely a mosaic method and a painting method, wherein the painting method is closer to the intention of gold and silver errors, gold fragments are firstly placed in a crucible for heating, and then mercury with seven times of gold content is added to dissolve the gold fragments into liquid, so that the gold fragments are prepared into the so-called mud gold. The bronze ware is then coated with a variety of intricate pattern textures with a mud gold, or within pre-cast grooves. Finally, baking with smokeless charcoal fire to evaporate mercury, and fixing gold pattern on the surface of bronze ware. The ancient gold-silver-wrong bronze ware in China is found to adopt a mosaic decoration method, and is called a gold engraving decoration method. A nine seven three years old, well-known scholars Shi Shuqing in China have published a "ancient gold-wrong technology in China" on "cultural relics", and are mainly speaking about the method. The manufacturing method comprises four steps, namely, the first step is to make a mother Fan Yu groove, so that gold and silver are embedded in the groove after the toilet is cast. The second step is a chipper slot. After the copper ware is cast, the groove is further required to be machined, chiseled and fine textured, a pattern is required to be drawn on the ware surface by an ink pen, and then a shallow groove is chiseled and carved according to the pattern, so that the ancient times are engraved, and the ancient times are also called engraving. The third step is mosaicing. The fourth step is to grind the sample. After the gold wire or the gold sheet is inlaid, the surface of the copper ware is not smooth, and the gold wire or the gold sheet and the copper ware are naturally smooth by grinding with wrong stones, so that the seam is tightly closed. The black copper silver-removing process is a special Chinese traditional copper handicraft in Yunnan, and starts from Yunnan stone screens. The method takes copper as a tyre, various patterns are carved on the tyre, then molten silver (or gold) water is filled into the patterns, the patterns are polished and smooth after being cooled, the bottom copper naturally turns black for a long time, and the patterns with the silver (or gold) patterns are penetrated out, so that the black-white (or black-yellow) distinct decorative effect is presented, and the method is ancient in fragrance, ancient in color, elegant and unique. 2. The black copper silver process, the special Chinese traditional copper handicraft in Yunnan, is initiated from Yunnan stone screen. The method takes copper as a tyre, various patterns are carved on the tyre, then molten silver (or gold) water is filled into the patterns, the patterns are polished and smooth after being cooled, the bottom copper naturally turns into black after a long time, the silver (or gold) patterns are penetrated out, the black-white (or black-yellow) distinct decorative effect is presented, the black-white (or black-yellow) antique color is realized, the refined black copper alloy is melted into the black copper alloy by high-quality copper and more than ten noble metals of gold and pure silver in a certain proportion. 2. Forging the black copper sheet, and forging, rolling and the like the alloy to obtain black copper sheets with different thicknesses. 3. The black copper sheet is chiseled with a pattern design, required pattern patterns or characters are drawn on the black copper sheet after cutting materials and blanking, lines are smooth, and various patterns are engraved by using a chisel. The depth of the etching is determined according to the thickness of the black copper sheet. 4. Silver and copper are removed and the most exquisite place of the silver and copper removing process is that pure psoriasis or pure Jin Jinxie is filled in the pattern to the full extent of 'removing'. The psoriasis or the gold scraps and the black copper are naturally melted into a whole after being treated at high temperature. 5. Welding and assembling are key to forming an artwork, and the quality of welding and assembling determines the final quality of a product by a process which is necessary for any piece of black copper silver artwork. Polishing, assembling and welding the silver-removed black copper sheet, or welding and assembling the manufactured black copper sheet on the related part of the designed and manufactured metalware to form a complete metalware. 6. Polishing and grinding, namely rough polishing and fine polishing, manually polishing, and cleaning and polishing the preformed object to make the preformed object show silvery white lines. 7. The black covering treatment process is to cover the palm, and knead the palm while covering after the hand sweats. The hand sweat contacts with the black copper for a long time to generate reaction, so that the surface of the black copper device is oxidized to generate a layer of natural oxidation protective film, and the black copper blank is in a black and shiny state, and the process has quite technical requirements.
Wherein, the gold wires or silver wires for the gold-silver misplaced vessels are round wires, and the first color is positive, and the second color is softer and easy to press. The gold and silver errors have extremely high artistic requirements on pattern lines, and the lines are lively and smooth and have consistent thickness like a painting brush for painting. Secondly, the slotting on the ware is very accurate, otherwise, the gold wire cannot be embedded. Even though the embedding is not firm, especially the pattern and the pattern of the gold plate and the gold wire are combined, the pattern is concentrated in arc lines, the slotting precision requirement is more strict, and the manufacturing difficulty is more. Because gold and silver wires of the gold and silver staggered process are all punched and pressed on the surface of an embedder and any adhesive cannot be used, the pattern lines are smooth, the slotting precision is accurate, the inlaying is smooth, no trace is generated on the wires, the difficulty of processing and manufacturing is conceivable, and one process is wrong and cannot be completed; the black copper silver-removing process has more steps, complex process and high process requirement.
