The surface of the gold jewelry is white and black because of gold in gold jewelry, when gold encounters mercury (mercury), it will reflect each other to generate "gold -mercury agent", that is, it becomes "gold -mercury alloy" " The color of this alloy is white. There are many types and brands of cosmetics nowadays. Some cosmetics contain trace mercury. It contains trace lead in using cosmetics or hair dyes. For the above two gold jewelry that has become white and black, it can be eliminated with gasoline spray guns for jewelry processing. Because the melting point of mercury and lead is very low, it will volatilize during the heating of the spray gun, so that the gold jewelry will restore the original face. Of course, it is best to wear gold jewelry when using cosmetics or hair dyeing to avoid posterior trouble. If people wear a golden ring on a finger, wearing a platinum ring on the adjacent fingers and a platinum ring on the adjacent fingers. Due to the frequent movement of the fingers, it is easy to cause the golden ring and the platinum ring. Rong each other, so that the surface of the gold jewelry is partially white and white. This situation cannot be heated with gasoline spray guns to disappear, because the melting point of platinum is hundreds of dollars higher than the melting point of gold. When gold is melted, the platinum is still "motionless". For such a white gold jewelry, you can polish it with agate knife, or you can rub it with thick cloth (such as canvas) to restore the gold to brighter. For 18KGP jewelry like the appearance and gold jewelry, the inside is generally copper or copper alloy, and the appearance is plated with a layer of gold. After using it for a period of time, the gold -plated layer that is often rubbed may be grinded or falling off, and the exposed copper or copper alloy is easily oxidized or chemically reacts with the sweat. The 18KGP gold -plated layer is cut off after fell off, and it can generally not return it to the original golden yellow, unless the electroplating process is processed again. The gold necklace's local darkening is mainly at the connection between the ring and the ring. Because the ring -to -ring connection of the necklace needs to be welded, welding medicines need to be welded during welding. The welded drugs used by various manufacturers are not necessarily the same. , Black phenomenon. When consulting in the mall, there are often people who change the old jewelry in the old jewelry: "The necklace I handed to them is golden yellow, and it is said that there are many small black spots on the necklace when returning to me?" This is you Burned with a spray gun as a test purity in the old replacement. It is not a place where the full gold is displayed. It is still golden yellow after the gold is burned. The welding medicine used in the necklace welding is insufficient. For the black caused by welding medicine, there is generally no way to return it to golden yellow, unless the entire necklace is re -plated and a total of 5 points, carefully see it! 1. The removal of dust should be cleaned to the dust and dirt of gold jewelry. The easiest way is to brush gently with a soft brush dipped in hot water. Scrubbing, but cutting should not be scrubbed with wear -oriented particles (such as toothpaste, polishing paste, fine sandpaper, or fine sand cloth, etc.) to avoid reducing the weight of the gold and causing losses.
2. When washing the pure gold necklace of the pure gold necklace, the pure gold necklace should be placed in the container, and then water is added to the container, and a small amount of ammonia water is added. Then the mouth is tightly covered, shaken back and forth, and then removed. When wearing a golden necklace, it should also be maintained with a buckle switch, and regularly drops a sewing machine oil to the switch to prevent the miniature spring in the switch rust.
3. The removal of gold jewelry white spots contains micro -mercury (mercury) in the commercially available cosmetics. For example, there are often phenyl hydroxyl mercury and skeleton meal chloride in the freckle cream. White spots or whiteness will appear after the gold jewelry is contacted. At this time, do not scrape or sandpaper with a small knife. As long as the white spots or white jewelry appear to bake in the fire, and then wipe it with a soft cloth, the gold jewelry will restore the original luster.
4. The surface dirt cleaning gold jewelry on the surface will be dull. At this time, you can use the flushing photos of the photo of the photo to flush it with the warm water from 30-40 ~ C, and dilute it with double the water. After soaking the dirt's gold jewelry for 4 to 6 minutes, use soft hair to use soft hair, then use soft hair. Wash the dirt and rinse with water several times. If you use fine woolen to dip the nail polish, the jewelry will be brighter.
5. Take warm water (40 ~ C) 1000 ml of warm water (40 ~ C), add 200 ml of methamphetamine to make a water solution, then put the gold jewelry into this cleaning solution for 10 minutes, then brush it with a brush, and then rinse it with water.
. If you take it to the gold shop, you must pay attention to the following three points:
. To choose a regular jewelry store, it is best to go to some large -scale and credible places, or check the qualification certification and business license of the jewelry store;
. It is best to understand the exact weight of your jewelry before cleaning, and record the weight. After processing, you must go to other departments in time and then call meter. When cleaning the jewelry, if the pungent smell is emitted in the solution, it is "Wang Shui". Remember to be careful to avoid losses;
