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.

Strategic significance highlights Sinopec official told reporters that China's newly discovered oil and gas reserves, deep, ultra-deep and shale gas and other unconventional oil and gas resources account for about 2/3, the efficient development of these resources is the country's energy security is an important strategic move , Is also the main battlefield in the field of oil and gas development. The conventional fracturing unit can no longer meet the extremely complicated and safe development of resources under the geological and surface conditions in our country. The use of large-scale fracturing units to rebuild oil and gas reservoirs is the decisive means to liberate "low porosity and permeability, large buried depth and high pressure" reservoirs.
Therefore, independent innovation and development of high pressure and high pressure oil and gas fracturing unit has important strategic significance. It includes a number of fracturing trucks, sand mixer, high pressure manifold system, with liquid vehicles, sand supply and cluster control systems, 3000 fracturing car is one of the best.
First, an integrated solution for shale gas exploration and development equipment was formed. Sinopec Machinery Company Shark Gas Exploration, which is formed by innovative products and technologies such as "Well Factory" drilling rig, Model 3000 complete set of fracturing equipment, composite bridge plug, coiled tubing, "Equal Threaded Threaded Drilling Machine + Smooth PDC Punch" Development of equipment and integrated solutions for China's first shale gas field - Fuling shale gas field commercial development, short-term built 5 billion square production capacity has played an important role in supporting equipment. At present, 32 sets of Model 3000 Fracturing Vehicles and a total of 67 sets of equipment have been produced and a total of more than 140 wells (2,350 layers) have been fractured to help Fuling Shale Gas Field become the largest page outside North America The gas field has significantly raised the overall technical level of oil and gas reservoir development in our country and provided important equipment support for China's energy security.
Second, the successful development of this project has successfully solved the difficult problem of commercialization of hard-to-use oil and gas resources in our country. The successful application of large-scale fracturing equipment in Chongqing, Sichuan, Guizhou, Xinjiang, northeast, northern Shaanxi and Inner Mongolia has solved the difficult problem of production and commercialization of the hard-to-use oil and gas resources in our country, and made the Changqing Oilfield, Puguang Gas Field, Yuan Dam gas field development has become a reality.
Third, become the main force of large-scale fracturing construction equipment in our country. In Daqing, victory, extension and other 16 fields are widely used in fracturing operations, in the oil and gas development has played an important role in the operation of equipment, highly praised by users. As of October 2015, 460 sets of large-scale fracturing equipment have been developed, accounting for 70% of the domestic market, becoming the major force in China's large-scale fracturing equipment.
Fourth, to achieve the key components exported to North America, the Commonwealth of Independent States and other countries and regions. The project formed three industry standards, enacted 15 enterprise standards, applied for 20 national invention patents, authorized 9 items, obtained 15 software copyrights, and published 87 papers. Established 6000hp fracturing pump test, 700MPa high pressure test and other 15 sets of test equipment to form an annual output of 700 fracturing pumps, high pressure manifold 100,000, a series of fracturing equipment 400 sets of production capacity. Developed fracturing pumps, high pressure manifold, control systems and other key components exported to North America, the Commonwealth of Independent States and other regions.
To achieve the four major innovations It is understood that the project team relies on major national science and technology projects, 863 scientific research projects support, through 10 years of continuous technical research, to achieve the four major innovations.
First, innovation has formed a lightweight and optimized integration technology for EHV high-power fracturing vehicles. It has developed the world's first 2500-type and 3000-type fracturing vehicles and raised the core capabilities of China's fracturing equipment. Second, innovation has resulted in the formation of a large-scale fracturing fluid whole process accurate and efficient mixing technology. The third is to create a UHV manifold design, manufacture, online testing and use of security technology system. A design method of high pressure manifold based on erosion mechanism and stress analysis was proposed, and a non-metallic sealing material evaluation and optimization technology under the condition of ultra-high pressure corrosion was formed. A 140MPa ultrahigh pressure manifold was developed. Fourth, innovation based on large-scale fracturing project equipment cluster control and application of technology.
The project "Development and Cluster Application of EHV High-Power Oil-Gas Fracturing Unit" independently developed by 8 universities and research institutes such as China University of Petroleum won the second prize of National Science and Technology Progress Award by SINOPEC Petroleum Machinery Co., Ltd. recently. Industry experts said that the advent and application of large-scale complete sets of fracturing equipment, building a complete system of fracturing equipment research and development, leading the development of the industry, enhance the level of research and development of fracturing equipment in China, marking China's fracturing equipment research and development ranks among the world's leading ranks.
