In order to prolong the durability of glass bead and prevent its spallation from paint after extruding by vehicles, these beads are coated with a special coating during the production process to increase the adhesion between glass bead and paint, so that can prolong the durability of glass bead above 20%.(It is usually used for surface treatment of Drop on glass beads).
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.

The power equipment sector has benefited from the rapid growth of grid investment, especially UHV investment, from January to July, and has consistently outperformed the broader market. In the absence of any change in the target for the whole year, the slowdown in investment growth in the second half of the year is an established fact, but it will flow to the distribution network that is lower than expected in the first half of the year. In addition, the inflection point of the wind power industry is coming. The low-voltage electrical appliance industry benefits from the recovery of real estate and the drop of raw materials, which is also worthy of attention.
Next year or usher in the peak of distribution network investment. From January to July this year, grid investment increased by 17% year-on-year to 1,947 yuan. Such high growth rate was mainly due to the concentrated delivery of UHV in the first half of the year. We believe that it will be impossible to maintain high-speed growth of more than double digits in the second half of the year, and the investment structure will also be maintained. However, we expect that the distribution network investment will usher in a peak next year, and the investment ratio will increase substantially, which will benefit distribution network equipment companies.
Distribution network automation construction will usher in the peak. The Standing Committee of the State Council will accelerate the development of distribution networks and smart grids as the focus of future work. Over the past few years, after the distribution network automation pilot project and demonstration project, the technical scheme for distribution network automation has gradually matured, and there is the possibility of accelerating promotion across the country. Future distribution automation investment is expected to continue to grow rapidly. Before the State Grid plans to reach 2015, its investment in distribution automation will reach 40 billion yuan. In the past, the annual investment was only 2-3 billion, and the market has the imagination to grow exponentially.
The wind power industry ushered in a turning point. China's wind power industry has undergone a great leap forward in the past few years, resulting in difficulties such as grid connection and frequent accidents. The industry entered a low point in 11 and 12 years. However, there were several signs in the end of the 12th and 13th years that led us to judge that the wind power industry had bottomed out, including stabilizing lifting capacity, doubling the number of tenders, resuming the improvement, and the price of wind turbines rising. The industry will usher in steady growth in the next few years.
The low-voltage electrical appliance industry benefited from the recovery of real estate and the decline of metals. The area of ​​construction of the real estate industry regained positive growth in the first half of 13 years, and the completed area has also maintained a stable growth rate, which is favorable for the demand of the low-voltage electrical industry.
From January to August, the prices of major raw materials, copper and silver, fell sharply. The US exit from QE is expected to continue to drive down raw material prices. It is expected that prices will remain weak in the second half of the year, which will benefit the gross profit margin of the low-voltage electrical industry.
The Chinese government has formulated a development plan for the high-voltage switch industry during the 12th Five-Year Plan period. Among them, the focus has been on strengthening the development of intelligent switches, and its technological development has also been related to the intelligentization of electrical components.
During the Twelfth Five-Year Plan period, China's high-voltage switch industry should take the opportunity of building a strong smart grid and rely on UHV AC and DC power transmission projects to enhance its independent innovation capability, greatly increase the level of intelligent switchgear equipment, and promote environmental protection, energy conservation, and emission reduction. Equipment; The UHV transmission technology and advanced electrical equipment and integration technology should be the key areas of development. In-depth research on 1000kV UHV transmission and key equipment and core technologies should be conducted to accelerate the complete localization of AC and DC high-voltage equipment; and through advanced electrical The pre-research of equipment and integration technology aims to make breakthroughs in the key technologies of superconducting power equipment; strive to promote the optimization and upgrading of industrial structure, further improve the overall technical level and international competitiveness of the industry, and strive to achieve the transformation of the high-voltage switch industry from big to strong. .
