Standards for Distinguishing the Quality of Epoxy
Standards for distinguishing the quality of Epoxy
(1) Transparency:
-High-quality epoxy: The resin should be transparent and clear, without impurities or yellowing. Good epoxy can make the pattern or color on the surface of the jewelry more vivid and three-dimensional.
-Poor-quality epoxy: If the epoxy appears turbid, yellow or has opaque particles, it means that the resin used is of poor quality or incomplete curing.
(2) Smoothness:
-High-quality epoxy: The surface is smooth and flat, without bubbles or uneven places, and feels delicate.
-Poor-quality epoxy: There are bubbles, particles or unevenness on the surface, which may be due to uneven mixing or impurities intrusion during the curing process.

(3) Adhesion:
-High-quality epoxy: The glue layer should be firmly attached to the surface of the jewelry, not easy to peel off or crack, and can remain stable after long-term use.
-Poor-quality epoxy: If the glue layer peels off or cracks easily, it means that the adhesion is insufficient and the service life is short.

Comparison of high-quality and low-quality epoxy
-Visual example
Visually, the surface of high-quality epoxy jewelry is like a layer of transparent glass, which can clearly see the pattern or color below, and the surface is smooth like a mirror. Inferior epoxy may have bubbles, turbidity, or even uneven edges, which greatly reduces the visual effect.
Grinding glue (also known as "polishing glue" or "polishing glue") is a process used in jewelry processing, mainly used to improve the gloss and smoothness of the jewelry surface. Its process flow usually includes the following steps:
1 Surface grinding: In the process of jewelry making, first use rough abrasives (such as sandpaper or grinding discs) to remove surface flaws and unevenness.
2 Applying grinding glue: Applying grinding glue on the surface of the jewelry. Grinding glue is usually composed of fine abrasives and adhesives, which can fill fine scratches on the surface and gradually form a smooth surface.
Polishing: Polishing the jewelry coated with grinding glue using a polishing machine or hand polishing tools. This process will gradually remove the tiny surface unevenness and make the surface of the jewelry smooth and shiny.
3 Cleaning: After polishing, the surface of the jewelry needs to be cleaned to remove excess polishing glue and abrasive residues to ensure that the surface of the jewelry is smooth and bright.
Why is polishing glue so beautiful?
The polishing glue and polishing process can effectively remove tiny scratches and flaws on the surface, making the surface of the jewelry smooth as a mirror and very glossy. The application of polishing glue can evenly fill the subtle unevenness on the surface of the jewelry, make the light reflection more uniform, and enhance the overall beauty.
-Sense of depth: The surface of the jewelry after polishing and polishing has a deeper sense, and the light can be better refracted, making the jewelry look more three-dimensional and delicate.

The polishing glue process plays an important role in the manufacture of jewelry. It can greatly enhance the appearance and texture of the jewelry, making it look more high-end and attractive, especially after the blessing of electroplating or electrophoresis, you can feel the luxury and silky enjoyment.
