1. High strength of ceramic beads : Dense crystalline phase structure, long impact life.
2. High density: Special formula with high specific gravity, solid without cavity, not easy to break; less dust, good sandblasting and good vision.
3. High sphericity: 90% sphericity, good fluidity of material, little wear on blast nozzle and blast pipeline.
4. Smooth surface: The polished surface is not easy to get wet; the surface of the parts is smooth and delicate, and the wear is low, which prolongs the life of the workpiece.
Craft ceramic beads are special ceramic beads for handicrafts. The firing temperature is higher than that of jewelry ceramic beads and lower than that of functional ceramic beads. It is somewhere in between. It refers to many crafts, connectors, ceramic machinery, ceramic grinding beads.
So how to distinguish ceramic beads ? Note the following:
1. Feeling of lightness and weight: Ceramic beads with good texture tend to have a higher density, because the soil quality is considered to be thoroughly cooked, so the density is higher; holding beads that do not have the feeling above is often because the density is small and the texture is not good enough;
2. Coolness: Because of the specific heat, good ceramic beads feel cooler when placed on the palm of the hand or worn on the hand, while the poor quality is not obvious;
3, ceramic bead texture: There are two types of bead patterns, one is color glaze, the other is decal (of course there are hand-painted, very few); good quality beads, whether color glaze or decal, texture Very clear, not turbid, and the color tone is relatively uniform;
