General situation and current situation analysis of capacitor industry
China capacitor market is the biggest market in the world, whether from the current level of manufacturing, or the demand for reactive power compensation in power system operation, have been to the capacitor manufacturing industry to convert ideas and further forward time, otherwise will inevitably be affected by the strong shock, the international companies in this regard, no matter is the capacitor manufacturing industry, or the user of electric power system, should be given sufficient knowledge. The following are the general situation and current situation analysis of the capacitor industry in 2017.
The role of capacitors in electronic circuits in general as follows: AC, DC resistance, with filtering, by-pass, coupling and fast charging and discharging function, and has the advantages of small volume, low cost, large capacity storage characteristics, along with the progress of modern science and technology and the performance of the capacitor is increasing, the products have been widely used in consumer electronics products, communication products, computer and peripheral products, instrumentation, automation, automotive industry, photoelectric products, high-speed railway and aviation and military equipment etc..
The capacitor industry has been growing rapidly, which has become a big producer of capacitor and a big exporter in the world. It meets the needs of domestic development and export.
According to the analysis of the development prospect and development strategy research of China's chip capacitor industry in the past 2017-2022 years, there are more than 600 capacitor factories in China. The old state-owned enterprises in the capacitor industry have shown a good momentum of development after restructuring, new product development capabilities have been enhanced, product market benefit has increased, economic benefits have improved, and they have entered the ranks of top 100 electronic components. The collective, township enterprises in the national policy support and guidance, continue to grow, has become the main force of capacitor, Guangdong Fenghua, Chaozhou Sanhuan, Xiamen Fala and other companies are 2012 China electronic components hundred enterprises, most of which have been successfully listed on domestic and overseas. Many foreign enterprises have become the main force of the export of capacitors. With the deepening of foreign-related economic restructuring and the development of trade and investment facilitation, many foreign enterprises set up factories in China, which has contributed to improving the technology level and international market share of China's capacitors.
At present, China's capacity sales volume is 63 billion 700 million yuan, accounting for 4.64% of electronic components sales volume of 13737 billion yuan, accounting for 24% of world sales, second only to Japan (26%), ranking second in the world.
Our capacitor industry is developed in the last century in 80s to promote the localization of TV of China before 1978 is not a capacitor automatic winding machine, automatic assembly machine, automatic welding machine, automatic measuring machine, through the "65" period to "85" at the beginning of each kind of capacitor on the introduction of production line more than 300, all kinds of automatic assembly machine, testing machine, packaging machine, marking machine, etc. up to 15000 units to 18000 units, vacuum coating machine of film capacitors have 80 units to 90 units, capacity of 20000 tons of film. Since then, the scale of the capacitor industry has been expanding, the technology level has been continuously improved, and the specifications are basically complete, which satisfies the needs of consumer products such as color TV, fridge, air conditioner, etc., but the development of chip capacitors is not fast enough. During the period of "85", chip components were listed as the newly developed industries with key development in China. They were listed in the list of foreign investment encouraged by the state. Foreign investment was booming. Joint ventures developed rapidly, and the varieties, output and import and export volume of China's chip capacitors increased rapidly. For example, the production of ceramic capacitors in 1995 is only 2 billion 460 million, and at present, the output is more than 716 billion 700 million according to incomplete statistics. In 2011, only 926 billion 506 million were exported. Chip tantalum capacitors, sheet aluminum electrolytic capacitors and thin film capacitors also provide matching and export.
In the last century after 90s, with the market especially the rapid development of mobile communication and so on, the capacitor of high frequency, high temperature and high pressure, the size of the increasingly high demand, on the one hand, the domestic manufacturers of capacitors based on digestion and absorption of imported equipment, in research and development, at the same time, wholly foreign-owned, joint venture also increased rapidly, the capacitor industry has become the world's rapid growth, capacitor production and export country, to meet the needs of the development of domestic demand and exports.
The industrial chain of capacitors has been basically formed. The manufacturing equipment and raw materials of capacitors have been formed to meet the needs of the capacitor industry and have been exported to overseas. In terms of equipment, vacuum coating machine, high precision and high speed cutting machine, automatic winding machine, empowerment can basically meet the demand of domestic equipment automatic machine and automatic welding machine, fluidized bed, but manufacturing high-grade capacitor lead-free devices such as ultra small chip production equipment, reflow soldering machine, metal film capacitor production still need to import equipment etc.. In terms of materials, polypropylene film, polyester film, metallized strip, CP line and other raw materials basically meet domestic demand, but also exported to South Korea, India, the United States, Brazil, Japan and so on. But high end electrolytic capacitor paper, high-end electronic slurry, ultra-thin medium high capacity electronic ceramics, high performance capacitor film and other materials are still dependent on import.
The management of the factory is basically in line with the international community. The enterprises have independent intellectual property rights and the products are rapidly upgraded. Capacitors enterprises on the basis of the learning foreign advanced management experience, technical index of capacitor products using the IEC standard, the main enterprises have implemented ISO9000 quality management system, ISO14000 environmental management system, OHSAS1800 occupation health and safety management system, CQC, UL, the Great Wall CSA, VDE and other eight deemed safe universal implementation. AC capacitors, anti-jamming capacitors, and high voltage capacitors have been made all over the world。
Capacitors for enterprises to strengthen the combination of enterprises gradually from the production and business transformation for the production of R & D and innovation pilot enterprises, many enterprises become a high-tech enterprises, some set up post doctoral research station, the establishment of provincial, national technology center, the provincial engineering technology research center, State Key Laboratory of other institutions, promote the the adjustment of product structure of capacitor and improve the technology level of enterprises. Guangdong Fenghua, Shanghai Feile enterprises so as to obtain the number of patents are more than 100.
The improvement of product technology level and upgrading and upgrading, such as the size of multilayer ceramic capacitors has been developed from 0603 to 0402, and has become the mainstream specification of the market. The 0201 type has been mass produced, and the 01005 type this year is available for mass production in Shenzhen Yuyang. The successful development and application of Ni electrode on the material has become a major milestone in the industry. Aluminum electrolytic capacitor is the life of the product from the original 1000 hours up to 2000 hours, have special requirements for up to 5000~10000 hours, the temperature increased from 85 C to 105 C, the highest to 125 DEG C, high frequency and low impedance products can replace the imported high voltage electric Nantong Jianghai solution swept Eurasia, challenge the small high voltage capacitor Hunan Aihua dare and Japanese ruby, ultra small aluminum electrolysis development soon, liquid chip capacitor Huawei, XinDa, Fenghua hi tech has a scale, solid polymer chip capacitors located in jianghai. High frequency, low impedance, long life and wide temperature are in the ascendant.
With the development of power system in China, whether it is the capacitor manufacturing industry products, or China's electric power system reactive power compensation has been a serious and not suitable for the current power system demand, therefore, whether the capacitor manufacturing industry, reactive power compensation technology have to must change the period or power the system, otherwise it will interfere with the power capacitor in China and the development of reactive compensation technology, and widening our technology gap with the international advanced technology. There should be a sober understanding of all of you who are here to promote the technology of reactive compensation.
Capacitor industry in our country to face the developed countries in the high-end product market, strategic emerging industries and other inherent advantages in the field of competition, to face the challenges of other developing countries in the labor-intensive products market, to deal with the RMB exchange rate change, labor and personnel costs and rising raw materials and energy prices and other factors in China will face a very arduous task. We have long-term planning in the country under the guidance of the development of a new generation of information technology driven, accelerate the upgrading of industrial structure, enhance the ability of independent innovation and competitiveness, realize the capacitor industry from large to strong changes, become the world's production of power capacitor.
