With the development of the world economy and the improvement of people’s living standards, natural stone (granite, marble), jade, artificial high-grade stone (micro-ceramic, glass, and cement products, etc.) have been widely used in the decoration of houses and buildings. It is used in the production of various decorations and applied to the construction of daily necessities, roads and bridges, and all kinds of diamond tools are required for the processing of these materials.
Germany, Italy, Japan, and South Korea have many varieties of diamond tools, high quality, and high prices. Their products account for almost the vast majority of the high-end stone processing market.
In the past decade or so, China's diamond tool manufacturers have developed rapidly. From the perspective of the number of enterprises, there are nearly 1,000 companies that produce diamond tools, and their annual sales revenue exceeds 10 billion. Danyang City in Jiangsu Province, Shijiazhuang City in Hebei Province, Ezhou City in Hubei Province, Shuitou in Quanzhou City in Fujian Province, Yunfu City in Guangdong Province and Shandong Province have nearly 100 diamond tool manufacturers. The number of companies that manufacture diamond tools in China is large and they are incomparable to any other country in the world, and they will surely become the world's diamond tool supply base. Some varieties of diamond tools in China also have a very high quality level. Some famous foreign diamond tools are also commissioned by Chinese companies. However, the vast majority of products produced by most companies are of inferior quality and low price. Although China exports a large number of diamond tools, most of them are low-priced products and are called “junkâ€. Even high-quality products whose quality meets or exceeds that of similar foreign products, because they are made in China, can not afford a good price, and seriously affect China's image. What is the reason for this situation? There are two main reasons for summing up.
The first is the low level of technology. The development of diamond tool production technology can be divided into three stages so far. The first stage is to use a simple powder for the carcass plus diamond using a mechanical mixing process to make diamond tools. This process is prone to segregation of components; high sintering temperature, easy to cause graphitization of diamond, reduce the strength of diamond. Since various carcass materials are mechanically combined and not fully alloyed, the carcass has a poor effect on the diamond inlay and it is difficult to produce high-grade products. The second stage is the use of pre-alloyed powders for the carcass plus diamond compounding process to make diamond tools. Due to the alloying of the carcass material and the low sintering temperature, this process does not reduce the diamond strength, avoids segregation of the components, produces a good effect of the diamond cladding, and makes the diamond function well. The use of pre-alloyed powder as a diamond tool for carcass production has the characteristics of high efficiency and slow decay, and can produce high-quality diamond tools. The third stage is the use of pre-alloyed powders for the carcass and the diamonds are arranged in an ordered (multi-layer, uniform diamond) technique. This technology is to accommodate the technical advantages of pre-alloyed powders. It also arranges diamonds in order to make full use of each diamond, and overcomes the defects that the uneven distribution of diamonds caused by the use of mechanical mixing process seriously affects the cutting performance. , is the latest technology for producing diamond tools in the world today.
Take the 350mm diamond cutting disc commonly used as an example, the cutting efficiency of the first stage technology is 2.0m (100%), the cutting efficiency of the second stage technology is 3.6m (rises to 180%), the third stage technology The cutting efficiency is 5.5m (up to 275%). Of the companies that currently manufacture diamond tools in China, 90% are still using the first phase of technology. Less than 10% of companies use the second phase of technology, and individual companies use the third phase of technology. It is not difficult to see that among the companies that currently manufacture diamond tools in China, a few companies are fully capable of producing high-quality products. However, most companies still use traditional, backward technologies.
The second is vicious competition. Diamond tools are consumables and have a large market demand. According to the current technology for the production of diamond tools in the first phase, it is relatively easy for new diamond tool companies. In a short period of time, there are nearly 1,000 companies producing diamond tools in China. Used commonly? 105mm diamond saw blade as an example, the product grade is "high quality", the ex-factory price is more than 18 yuan, about 10%; the product grade is "standard", the ex-factory price is about 12 yuan, about 50%; product grade is "Economy", the factory price of about 8 yuan, accounting for about 40%.

These beads are coated with a special coating materials, during the manufacture of the glass beads, which will improve the characteristics of moisture-proof and adhesion of glass bead. In the way, the life cycle of the glass beads can be prolonged and this enhances the beads reflectivity in a rainy night. These beads are usually used in white or yellow line-construction of highway.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
