China becomes the world's largest diamond market in the world

On September 28, experts from the National Special Minerals Materials Engineering Technology Research Center of Guilin Institute of Mineral Geology revealed that the world now produces 5 billion carats of synthetic diamond per year, of which 4 billion carats are produced in China, accounting for the international market. Eighty percent, China has become the world's largest diamond in the world.

It is reported that in the 1950s, synthetic diamond was first successfully developed and applied in the United States. In the 1960s, China developed synthetic diamonds with independent intellectual property rights. It was widely used in the geological drilling industry and other fields in the 1970s.

After several decades of development, China's various tools with independent intellectual property rights, which are made of synthetic diamonds as superhard materials, have also been widely used in machining, stone cutting, geological drilling, electronics, and defense industries, and have regained the experience of foreign manufacturers. In the market of 70% of the monopoly, in recent years, it has begun to make great strides to go abroad and move to the international market.

At present, there are more than 200 synthetic diamond manufacturers in China, distributed in various provinces, municipalities and autonomous regions in China. The manufacturers with large scale and large output are mainly distributed in Zhengzhou, Henan, Guilin, Tianjin, Guizhou, Beijing and other places in Guangxi. In addition to domestic demand, it is mainly exported to Europe, America and Asia Pacific.

Experts here said that synthetic diamond is a kind of artificial crystal. In the 21st century, various artificial crystals are increasingly replaced as key materials in the high-tech fields such as microelectronics, optoelectronics, telecommunications, aerospace, aerospace and modern military technology. The importance of scientists from all over the world.

After more than half a century of development, China's artificial crystal industry has achieved remarkable achievements. Many kinds of artificial crystal growth technology ranks internationally advanced or advanced. Only Guilin Institute of Mineral Geology has many advanced international standards. China's blank artificial crystal technology such as emerald, corundum, cubic boron nitride and zinc oxide with independent intellectual property rights. China's brand of nonlinear optical crystals has a worldwide reputation. Some important crystals have met the needs of major domestic projects. A number of high-tech synthetic crystal crystals have been exported abroad.
 

Meat Lighting

Meat product lighting is a lighting solution specifically designed for the environment in which meat products are displayed and sold. It aims to highlight and accentuate the texture, color, and freshness of meat products by providing appropriate lighting to attract customer's attention and boost sales.

The design of meat display lighting takes into account several factors. The first is the meat case lighting intensity and color reproduction ability. Meat products need plenty of light to show off their true color and texture while highlighting freshness. By choosing lamps with a high color rendering index, you can ensure that meat products present a more realistic, natural color.

The second is the direction and Angle of lighting. Proper lighting direction and Angle can reduce shadows and reflections, so that the surface of the meat product is more evenly illuminated, avoiding unnecessary light background interference.

In addition, temperature control is also an important consideration for meat product lighting. Too high lighting temperatures may cause meat products to spoil or fade, so it is crucial to choose low-heat lighting.

Through reasonable lighting design of meat products, businesses can enhance the attractiveness of meat products, show their quality and freshness, and increase sales. At the same time, proper lighting also helps to enhance the comfort of the shopping environment and create a more pleasant shopping experience for customers. It is important to ensure the use of lamps that meet food safety standards and to choose the appropriate lighting scheme for different meat product types and display areas.
