On September 2, the 26th China International Composites Industry Technology Exhibition (hereinafter referred to as CCE2020) was successfully held in Shanghai.
The punctual convening of CCE2020 has set up the best stage for domestic and foreign composite companies to find customers, exchange technologies, and promote innovative products. Many exhibitors have expressed that they have been looking forward to the exhibition for a long time and regard it as the industry's recovery. Iconic event.
The wind power market is growing faster and related industries are developing rapidly
A notable feature of this year's exhibition is the complete wind power blade industry chain and numerous related companies. At present, wind power is one of the most mature, large-scale development conditions and commercial development prospects in the field of renewable energy. The available wind energy is widely distributed and has huge reserves worldwide. At the same time, as wind power related technologies continue to mature and equipment upgrades, the global wind power industry is developing rapidly. According to GWEC statistics, as of the end of 2019, the cumulative installed capacity of global wind power was 651 GW, an increase of more than 26 times over the end of 2001, with an average annual compound growth rate of 20.12%. It has been learned from some exhibitors that fan blades have become the hottest product after Coronavirus (COVID-19) pandemic, and related industries have developed rapidly, and demand has increased significantly.
From the perspective of newly installed capacity, the newly installed capacity of global wind power in 2019 was 60.4GW, an increase of more than 8 times compared with 2001, with an average annual compound growth rate of 13.18%. As one of the fastest-growing renewable energy sources at this stage, wind power accounts for an increase in the global power production structure year by year, and has broad development prospects. According to GWEC's forecast, the world will add more than 355GW of installed capacity in the next five years, and between 2020 and 2024, the annual new installed capacity will exceed 65GW. In 2019, the top five countries in the world for new installed capacity on land are China, the United States, India, Spain and Sweden. The newly installed capacity on land accounted for 44%, 17%, 4%, 4% and 3% of the newly installed capacity of global onshore wind power in 2019, and the total proportion was 72%.
For China's wind power industry, policy drivers have played a key role. At the same time, from the perspective of China's domestic energy ratio, although wind power has become the third largest source of power after thermal power and hydropower, the wind power generation in 2019 was 4,057 100 million kilowatt-hours, accounting for only 5.54% of the national power generation. Therefore, when it comes to market expectations after the wind power incentive policy declines, both blade companies and related supporting companies are unanimously optimistic about the stable growth of the wind power market.
As an important part of wind power, offshore wind power is developing rapidly with the support of technology and policies, and vigorously speeding up the development of global wind power. Due to the abundant offshore wind resources and stable wind sources, the development of wind farms from land to sea has become a new trend in the world.
The advantages of offshore wind power are mainly that the wind speed is higher than that on land, the vertical wind shear change is small, the turbulence intensity is small, the signal dominant direction is stable, and the annual utilization hours are long. In addition, offshore wind power does not occupy land resources and is close to the coastal power load center, which can be absorbed locally to avoid resource waste caused by long-distance power transmission. In 2019, China's newly installed offshore wind power capacity is still less than 10% of the newly installed capacity of onshore wind power, which has huge development potential.
In terms of offshore wind power, JSZF Composite Material Technology Group Co., Ltd. has been investing great energy in innovating wind power blades in recent years and has achieved a series of results. At present, the company has a series of high-performance blade products of different lengths and powers adapted to different complete machines. At the same time, we can also customize specific models of blade products for customers. All the latest production processes-shell prepreg laying technology, vacuum infusion, carbon fiber vacuum infusion and carbon fiber prepreg technology, have been successfully applied to mass production.
In recent years, JSZF has undertaken the construction of the Jiangsu Provincial Key Laboratory of Offshore Wind Turbine Blade Design and Manufacturing Technology, dedicated to the research and improvement of common technologies in the industry such as blade aerodynamic and structural design, molding process, inspection and testing, and has achieved fruitful results. Provided wind turbine blades for Shanghai Donghai Bridge, Shanghai Lingang, Jiangsu Rudong, Fujian Pinghai Bay, Fujian Xinghua Bay and other offshore wind power projects. Exported LZ68.25-6.X, LZ62-5.0 and other offshore wind turbine blades to Europe , Japan, the cumulative installed capacity of offshore wind turbine blades sold is nearly 1000MW.
The Sinoma85.6 offshore low-cost all-glass fiber large blade of ZCKJ Wind Power Blade Technology Group reduces the use cost of offshore wind power. The product uses a glass fiber epoxy resin material system with relatively low material cost; adopts eggshell single layer The skin design structure type greatly reduces the design weight of the blade, and based on the characteristics of the offshore operating environment and the high maintenance cost, the advanced anti-corrosion technology and lightning protection technology are used to improve the adaptability of the blade in the harsh environment.
Sinoma 85.6 blades are suitable for S-type wind areas, 6.45MW/8MW series offshore wind turbines, and are all-glass fiber offshore blades completely independently designed and developed. The Sinoma 85.6 blade adopts a new aerodynamic shape and structure design. The length is 85.3m, the diameter of the wind wheel is 175m, and the maximum chord length is 4.88m. The sweeping area is 23891m2, equivalent to 3 or 4 standardized football fields, which is the largest single-machine power in China. All glass fiber blades.
SHSW New Materials has launched a new prepreg resin SWANCOR 2591 and carbon fiber infusion & carbon glass hybrid infusion resin SWANCOR 2519-2A/BS for key components such as main beams of large wind turbine blades, and as always upholds the concept of green energy, environmental protection and safety. Continue to interpret the style of "composite materials expert".
SDTS Fiberglass Technology Group focused on displaying a series of high-end and multi-functional new products such as ultrafine fibers, alkali-resistant fibers, wet-laid mats, pultruded panels, etc. The application scope covers wind power, automobiles, communications, and construction fields, which have attracted great attention in the industry. It fully demonstrates SDTS's rich product categories and persistent pursuit of innovation.
At this exhibition, ZGJS Glass Fiber Technology Group mainly promotes ultra-high modulus wind power yarn E9-390, a new generation of general-purpose direct yarn 386H, high-strength, fast-permeable high-pressure pipe yarn 308S, and high surface performance integrated bathroom yarn 410J, etc. product. The E9 glass fiber with a modulus exceeding 100GPa has become the focus of the glass fiber industry. It has more possibilities in the high-end application of glass fiber composite materials, attracting the attention of many viewers. In order to better explain to the audience the application of E9 glass fiber in blade production, Zhang Lin, deputy director of ZGJS research center, and Xu Shengjie, director of the second department of product research and development center, made a work entitled "E9 ultra-high modulus glass fiber and super large wind blade The technical lecture of "Solutions for Yarns" mainly introduces the company profile, E9 ultra-high modulus glass fiber and yarns for ultra-large wind blades that the industry pays close attention to.
