3 thoughts on “Gold jewelry should be polished for several processes, please please.”

  1. There are three procedures for polishing, namely grinding, polishing, and restoration.
    1, grinding: The dirt on the paint is cleared by the surface pre-processing to eliminate severe oxidation, minor scratches and surface defects. Most of the processes use water sandpaper to remove surface defects. Generally, 3M 1500-2500 Huangpi water sandpaper is used.
    2, polishing: polishing is further flat paint after grinding. Except for the grinding residual stripes, the polishing agent makes the paint surface naturally presented. After grinding the sandpaper, the surface sandpaper marks are further removed to restore the flatness and initial gloss of the paint surface.
    3, restore: retrieve the original face of the car, restore the state of a new car. Use a grinding agent in small blocks in the inconspicuous place. The abrasives are preferred to use mild abrasives. If the paint surface defects are serious, consider using moderate or severe abrasives.

    Coltic polishing method:
    1, mechanical polishing: mechanical polishing is cutting by cutting, material surface plastic deformation, remove the polished method of polishing, and obtain a smooth polishing method. Generally, oil stones are used. Strips, wool wheels, sandpaper, etc. are mainly manual operations, and special parts such as rotation surface.
    2, chemical polishing: Chemical polishing is to allow the material to make the material slightly protruding from the surface of the chemical medium than the concave part of the concave part, so as to obtain a smooth surface.
    3, ultrasonic polishing: Put the workpiece into the abrasive suspension and place it in the ultrasonic field together, rely on the oscillation of the ultrasonic, so that the abrasive is grinded and polished on the surface of the workpiece.

  2. Gold jewelry polishing: After burning gold jewelry with fire, put it in a dilute sulfuric acid or dilute hydrochloric acid that is prepared proportionally, you can remove debris such as dirt on the gold jewelry. Then remove the jewelry and rinse the jewelry with water to clean the residual dilute sulfuric acid or dilute hydrochloric acid (can be repeatedly operated). Prepare the solution in proportion in proportion of detergent or saponin, and use the hard and sharp stainless steel rods or agate sticks to dip the prepared solution. The jewelry is shiny. Then rinse the solution that remains on the gold jewelry with water, remove the water, and wipe it on the gold jewelry with a clean dry cloth or dry velvet cloth, and the gold jewelry will emit its unique light. Friendly reminder: The above is purely polished by hand. The mechanical polishing is not stainless steel rods or agate rods, but uses stainless steel beads (needles) or agate beads (can also be mixed) for polishing. Hope our answer can help you.
