Everyone should be familiar with glass beads. Small marbles from childhood, etc., are glass beads. The history of glass beads is relatively long. It does not exist in a separate period of time. In ancient times, there was glass. Glass beads are also used in glass beads. Glass beads have a wide range of uses. In ordinary processes, they are a unique abrasive, mainly used in sandblasting equipment. Glass beads are crushed from high-quality glass. The broken glass should be melted into a spherical shape, and then annealed to eliminate internal stress and prevent damage. The chemical composition of glass beads is inert and non-toxic. During use, there will be no iron or other substances remaining on the surface of the workpiece, and it will not cause some influence on the surroundings. Let's take a look at the development process of glass beads, from ancient times to modern times. Ancient times: In ancient times, glass beads were used as a symbol of power, and they were widely used by many nobles of the Wang family, and they have existed since the Western Zhou Dynasty. It became popular during the Warring States Period. Almost all of the glass ware in the tombs of the Warring States Period excavated have glass beads. Its development is inseparable from the continuous improvement of technology and equipment, and the cleaner glass texture. At the same time, people use less jade for decoration, which cannot meet people's requirements, which promotes the mass production and exquisiteness of glass beads. From the use of glass beads to the beauty of their appearance, they have attracted many people’s attention and patience. The application of our glass beads has slowly evolved to the current application of glass beads. According to historical archaeologists, in 1978, Hubei Province The world-renowned set of chimes were unearthed from the tomb of Marquis Yi in Leigudun, Suixian County, as well as many glass beads, which are widely used as funerary objects. Their shapes, colors, etc., are very beautiful, and their existence is very intact. Modern: The application of modern glass beads is quite extensive. Its beautiful appearance is widely used by people, especially as ornaments. The glass beads are usually inlaid with various glass beads in clothing exhibitions, and they are illuminated by lights. At present, the main production areas are located in the Floating Pearl Market in Qingdao City, Shandong Province and Yiwu, Zhejiang Province. From a national perspective, Shandong and Zhejiang are the two largest glass bead production and sales areas. Due to a wide range of demands, we are becoming more and more mature in the process of applying glass beads. In addition to being used as decoration, our glass beads are also widely used on traffic road signs. They have a strong reflective effect and high refraction effect. They are resistant to road traffic. The main production area of u200bu200broad reflective glass beads is concentrated in Daqing, Heilongjiang. Most trading companies are concentrated in Yongqing County, Hebei Province, mainly buying from Daqing. Large-scale domestic glass bead manufacturers include Daqing Lutong Technology Co., Ltd. and so on. Reflective glass beads are divided into ordinary glass beads and high refractive index glass beads. Ordinary glass beads are mainly used for road coatings, with a refractive index greater than or equal to 1.5. High refractive index glass beads are mainly used in reflective fabrics, such as traffic police clothes, highway signs and other places. These show where the practical value of glass beads has been improved. In addition to the above-mentioned aspects, there are many that we have not mentioned.
