is rose gold real gold or just a plating

The common gold plating process was as follows: ** 1. Electroplating process ** 1. ** Deconstruction and cleaning ** - Alkaline washing: Use an alkaline solution such as a solution of soda to remove organic matter such as grease. - Acid washing: use sulfuric acid, sulfuric acid and other acid cleaners to remove the metal surface of the rust layer and rust. - Washing with water: removing the residue after the alkali-washing and acid washing. 2. ** Undercoat ** - selecting Ni, copper, and the like as the plating base material, using the object to be plated as the negative pole, Ni or copper as the positive pole, and dissolving the positive pole through the current in the bath to form a plating base layer on the surface of the object to be plated. The methods of plating the base layer include plating, chemical plating, and the like. 3. ** Gold Plating ** - Metal gold was used as the material, and the metal gold of the positive pole was dissolved and plated on the negative pole (the object that had been plated) through the current in the bath. The thickness of the gold plated layer could be adjusted from a few millimeters to dozens of millimeters according to the needs. 4. ** Electrolyte adjustment ** - The composition and process conditions of the Electrolyte were adjusted. The commonly used Electrolyte components were acidic cyanide-based Electrolyte and alkali-based Electrolyte to ensure that the coating was uniform, smooth, and stable. 5. ** Post-processing ** - Washing: Remove any remaining liquids. - Neutralization: Neutralize acidic and acidic residue. - Dry: Remove moisture. - [Polishing: Makes the gold-plated layer brighter and smoother.] ** 2. Electroless Gold Plating Technique ** - The product that needed to be gold-plated was placed into the gold-plating solution. The melted gold atoms reacted with the chemical to form a gold-plated layer on the product. The chemical gold-plating did not require a direct power supply. ** 3. Other gold-plating process examples ** 1. ** Copper and Brass Gilding ** - Using organic liquids to remove oil: Use gasoline or carbon dioxide to remove the oily stains on the electronic components. - Supersonic chemical oil removal: This step is carried out after the oil removal with organic solution is completed. - Washing: Hot water, cold water, acid washing (a mixture of sulfuric acid, nitric acid, and water), and soaking in a solution of soda. - Gold plating: Use a gold plating solution that contains gold potassium cyanide and potash to carry out gold plating. - Washing and drying: Wash with ultrasonic agitation in purified water at 70 - 80 ° C (the electrical conductivity of purified water should be less than 10us/cm) for no less than 10 minutes, and finally dry. 2. ** Phosphor Bronze Gilding ** - Gasoline to remove oil stains: First, use gasoline to remove the oil stains on the electronic components. - [Supersonic chemical oil removal: This step will be carried out later.] - Washing and acid washing: hot water, cold water, and acid washing. - Gold Plating: Use a gold-plating solution containing gold potassium cyanide and potash to plate gold. 3. ** Gold-plated process of special golden finger lead wire (a special case)** - The processing of the printed circuit board (PC) was to form a connection module with broken gold-plated leads on the outer circuit. - "Ink resistance printing: Print a carbon ink resistance between the connecting modules at both ends, and use the carbon ink resistance to conduct the connecting modules at both ends. - Gold-plated: Use the connection module and carbon ink resistance to gold-plate the predetermined gold-plated pad position of the printed circuit board to complete the production of the golden finger. There were the following steps to recover and refine the gold-plated waste: - To prepare the gold removal powder, add the gold removal powder into hot water, stir it to accelerate the dissolution, and let it settle. - Gold removal: The electronic waste was added to the gold removal water, and the agitation accelerated the gold removal. - Acid adjustment: After removing the gold, add lemon acid to adjust the acid. Stir to accelerate the dissolution and test the acid. - "Substitute oxidization: Add in the zinc-wire, and after two hours of substitution, it will be oxided. Then, add in the solute to start the oxidization. - Impurity removal: such as adding impurity removal agent, heating to remove impurities, cleaning sponge gold, etc. In addition, there was another gold-plating process, which was three spraying and two baking, that is, spraying the primer → drying → spraying the reaction layer → spraying the topcoat → drying.

Gold gilding and gold-plating were essentially the same process. The first step was to prepare the gold amalgam. First, the gold had to be thinned and cut into pieces, then placed into a pre-heated crucible, and then injected with mercury. The ratio of gold to mercury was 1:5 - 1:7, so that it was mixed into a paste. During this process, the surface of the object needed to be cleaned with an acid and base solution. Then, it was time to apply the gold. The gold amalgam was evenly applied to the surface of the object (such as bronze). Next was to crack the gold. By baking the plated object, the mercury would evaporate and the gold would remain on the surface of the object. Finally, it was calendering to make the coating more dense and bright. When the operation was done, the color of the coating could remain unchanged for a long time. This kind of craft could be used to decorate building components such as copper and iron and various utensils. In ancient times, apart from being used on the surface of utensils, it was also used to gild weapons. The entire process usually needed to be repeated about three times, but to achieve a better gilding effect, it was common to repeat it five to seven times.

When analyzing the reaction mechanism between the flux and the gold plating layer, it was necessary to consider the situation of different bottom gold plating. For the mainstream method of nickel-based gold plating, during the welding process, the actual welding layer was related to the bottom layer of nickel-based alloy, that is, the tin alloy and nickel-based alloy formed a metal compound (Sn-Ni <2> compound). However, the purity of the gold-plated layer, the rate of voids, and the cleanliness of the surface directly affected the solderability of the contact body. When there was a nickel-plated bottom layer, the inertia of the nickel-plated part was higher than that of the gold-plated part, which could ensure a higher resistance to atmospheric corrosion. During welding, the flux and the bottom layer of nickel-plated part would have a smelting reaction, and the gold-plated layer might affect the welding process due to its own characteristics, but it was not the main reaction layer. As for the gold plating on the copper base, the copper base had a certain role in the welding. The copper ions easily penetrated into the gold coating and caused the gold coating to change color. Moreover, the copper coating was easy to be deactivated in the air and affected the cohesion of the gold coating. When the flux was in contact with the gold-plated layer of this structure, on the one hand, it had to deal with possible problems such as the possible oxidization of the copper surface to achieve good welding. On the other hand, the gold-plated layer was affected by the change of the copper layer and showed different solderability during welding. However, this method was rarely used at present. As for the silver plating, due to the lack of sufficient information, it was difficult to accurately analyze the reaction principle between the flux and it. It was only known that when the silver plating layer was contaminated, the black color would appear through the pores of the coating. This process was rarely used (except for special requirements). Generally speaking, when the flux was used in the welding process related to the gold-plated layer, it would be affected by the properties of the underlying metal under the gold-plated layer and the characteristics of the gold-plated layer (such as purity, voids, cleanliness, etc.). The reaction principle of the gold-plated layer and the flux with different underlying structures would have different performances in the welding process. The smelting change of the underlying metal during the welding was a more critical part, but the characteristics of the gold-plated layer could not be ignored. Under the joint action of many factors, the welding effect would be affected. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The material used to draw gold could be real gold. For example, in the process of drawing gold on porcelain, the process of drawing gold on a rock plate, etc., it was mentioned that the original (real gold) was used to draw patterns, or the real gold material was used to create the effect of spraying gold through the ink-jet process. However, there were also cases where gold powder was used for decoration, so the gold was not necessarily real gold. The novel "Gilded Palm" is equally exciting.

Rose gold was a kind of gold color that was slightly pink, also known as pink gold. It wasn't as soft and cute as pink, but it had a hint of dark high-class aura. It was similar to rose Quartz, but it also had a metallic texture. It would deviate according to the angle and the strength of the light. Sometimes it was as light as gold, and sometimes it was as dark as red. It was more interesting than pure pink. Judging from the values, it looked like a combination of rose Quartz and metallic color. It was reflected in different items, such as rose gold jewelry, the rose color of the iPhone, rose gold Moutai, rose gold earrings, and so on. The original work was equally exciting.
