In recent years, with the booming domestic auto, electronics, communications and other industries, China's demand for new materials industries has risen sharply. In 2013, dozens of raw materials in China were ranked, but some new materials with excellent performance or special functions had to rely on imports.
To develop a new material industry, we must first understand what materials are mainly referred to by new materials. What are the current policies and industries that are driven by the development of new materials? What are some of the foreign countries that are worth learning and learning from... The reporter visited Mr. Chen Shixin, Director of the Work Department of Shanghai New Materials Association, let us listen to his views.
Q: The “Decision on Accelerating the Cultivation and Development of Strategic Emerging Industries” issued by the State Council on October 10, 2010 lists new materials as one of the seven strategic emerging industries. The new material industry mentioned here mainly includes What materials? What are the policy orientations for developing new materials industry in China?
Chen Shixin: New materials refer to new materials with excellent performance and special functions, or materials with improved performance and new functions after the improvement of traditional materials. Currently, they mainly include special metal functional materials, metal structural materials, and advanced polymer materials. , new inorganic non-metallic materials, high-performance composite materials and cutting-edge new materials.
The policy orientation of developing new materials industry in China is very clear and the goal is very clear. The “12th Five-Year Development Plan for New Materials Industry” compiled by the Ministry of Industry and Information Technology clearly states: By the end of the “Twelfth Five-Year Plan”, the total output value of new domestic materials will reach 2 trillion yuan, with an average annual growth rate exceeding 25%; Consolidate ten major industrial bases, including: rare earth functional material base, rare metal new material industrial base, high quality special steel base, new light alloy material base, special rubber base, engineering plastic base, high performance fluorosilicon material base, special glass Base, advanced ceramic base, high-performance composite material base; comprehensive support capacity of new material products increased to 70%, key new material support capacity reached 50%, carbon fiber, titanium alloy, corrosion-resistant steel, advanced energy storage materials, semiconductor materials, The key varieties such as membrane materials, butyl rubber and polycarbonate are industrialized and scaled.
Question: What is the current status of China's material industry development?
Chen Shixin: In 2012, the output of dozens of raw materials in China was ranked. For example, crude steel production accounts for 44.3% of global production, electrolytic aluminum accounts for 65%, refined copper accounts for 24%, cement accounts for 60%, glass accounts for 50%, chemical fiber accounts for 42.6%, and chemical fertilizer accounts for 35%. Domestic overcapacity, exports have encountered various obstacles, and new materials with excellent performance or certain functions have to rely on imports, such as importing more than 10 million tons of steel every year, in addition to large diameter polished silicon wafers for the microelectronics industry. Fine chemicals such as photoresist, lead frame copper, and various materials used in large passenger aircraft are almost entirely imported.
In recent years, some key technologies in China have made major breakthroughs: production technology of niobium alloy, amorphous alloy, high magnetic induction oriented silicon steel, diphenylmethane diisocyanate (MDI), meta-aramid and super-hard materials. Has reached or approached; metal structural materials, inorganic non-metallic new materials and high-performance composite materials have significantly enhanced ability, advanced self-sufficiency of advanced polymer materials and special metal functional materials; rare earth functional materials, advanced energy storage materials, photovoltaic materials, Silicone, superhard materials, special stainless steel, glass fiber and composite materials.
Q: The huge demand in many application fields in China is driving the rapid development of the new materials industry. Specifically, what kind of application market do you think is currently driven by China's development of new materials industry?
Chen Shixin: New materials can provide support and guarantee for many industries, and these industries also provide a broad market space for the development of new materials industry. I am concerned about six major industries:
Information industry: China maintains the world's largest integrated circuit consumer market, accounting for about one-third of global consumption, while the self-sufficiency rate is less than 1/4. Up to now, there are no fewer than 20 Φ8” IC production lines built and under construction, and 12 Φ12” IC production lines have been built, under construction and under construction, of which the Yangtze River Delta region accounts for more than 70%. It is estimated that in 2015, Φ8-inch polished sheet will be 10 million pieces/year, Φ12-inch polished sheet will be 2.4 million pieces/year; circuit frame with precision copper strip will be 60,000 tons/year; in addition, photoresist and o-cresol epoxy resin will be used. , ultra-clean high purity reagents, high purity gas, low-k and high-k dielectric materials.
New energy industry: “Twelfth Five-Year Plan” China’s wind power increased by more than 70 million kilowatts, in addition to the need for rare earth permanent magnet materials of 40,000 tons, high-performance glass fiber 500,000 tons, carbon fiber and 900,000 tons of high-performance resin materials, due to sand or Seawater erosion, but also to develop wear-resistant, corrosion-resistant, anti-aging coatings; in the same period China needs to build 5 million kilowatts of solar power plants, thin batteries and dye sensitization and other new batteries are expected to further improve the cost performance, about 40,000 tons of polysilicon, slurry Low-iron suede rolled glass 50 million square meters, thin film battery target, etc.; construction of nuclear power 40 million kilowatts, annual steel 70,000 tons, nuclear zirconium and zirconium alloy ingots 2000 tons. Also develop B4Cp composite sheets.
New energy vehicles: By 2015, the total production and sales of new energy vehicles will be 500,000 units, and the power battery module needs energy type of 15 billion watt-hours/year, power type of 3 billion watt-hours/year, rare earth catalytic materials; lithium-ion battery separators of 100 million square meters. m/year; lithium hexafluorophosphate electrolyte salt 1000 tons / year, cathode material 10,000 tons / year and high specific capacity alloy or carbon-based anode material.
Aviation industry: China will need 3,770 new aircraft in the next 20 years, with a total price of about 490 billion US dollars. There are three main types of aviation materials: structural materials. From 2020, 4,000 tons of aluminum-lithium alloys, 2,000 tons of high-temperature alloys and high-performance titanium alloy die forgings will be required. The proportion of carbon fiber and composite materials will increase significantly. The functional materials are mainly controlled. Electronic functional materials for communication and communication equipment; interior and exterior decorative materials are relatively easy to enter, but all materials must have airworthiness arguments.
Environmental protection industry: During the “Twelfth Five-Year Plan” period, the annual output of energy-saving lamps in China will reach 3 billion, and the rare earth phosphors will need about 10,000 tons/year; the national new wall materials will exceed 23 billion square meters per year, and the output value of thermal insulation materials will reach 120 billion yuan / year; thermal power flue gas denitration catalysts and carriers demand will reach 4 billion yuan / year, the market demand for high temperature, corrosion resistant bag filter and water treatment membrane materials will increase significantly.
Biomedical industry: Since 2015, China needs 500,000 sets of artificial joints, 1.2 million vascular stents, 1 million intraocular lens crystals, artificial polymer materials such as artificial skin and tendons, and degradable plastic PLA.
Q: What are the hot spots and development trends in the development of new foreign materials?
Chen Shixin: As far as I can see, the development of new foreign materials has the following hot spots: graphene is getting closer to industrial application; invisible materials and cryptic materials are driving new developments in military industry; OLED display materials and quantum dot prototypes have been on display Energy materials are becoming more and more efficient; electronic information materials are recovering; biomedical materials are in a large capacity and are developing rapidly.
As far as the development trend of foreign new materials is concerned, I have the following experiences: the trend of low-dimensionalization of materials is obvious; the integration of new materials technology with information technology, biotechnology and energy technology; the integration of structural functions and functional materials; Environmentally friendly properties such as low carbon, green, and renewable recycling of materials preparation technology have attracted much attention; materials are developing toward integration and integration; surface coating or modification is widely used, economically reasonable, and has broad development prospects. technology.
Q: According to the statistics of Shanghai Statistics Bureau, the output value of new materials in Shanghai in 2012 was 170.78 billion yuan, accounting for only 19.9% of the entire material industry. What challenges do you think currently exist in Shanghai's development of new materials industry? What advice do you have for this?
Chen Shixin: Indeed, the output value of new materials in Shanghai accounts for only one-fifth of the total material industry. The innovation drive and transformation of the materials industry has a long way to go. I believe that there are still some challenges in the development of new materials industry in Shanghai: the innovation mechanism has not been perfected, and it is difficult to establish a close cooperative relationship between industry, academia and research. The scientific research results lack the testimony, and the conversion rate of results cannot be improved. Most of the speculative instruments are idle, the funds for SMEs are limited, the commission fees are high, and the lack of system testing makes it difficult to improve the quality of products. Foreign manufacturers are good at price wars, and domestic products are not available in foreign countries. They competed at the price, dispelled the enthusiasm of the company to change production, and it was difficult to maintain the risk of production. The foreign manufacturers set up multiple sales outlets in China, the agents were flexible, and the personal interests often played a decisive role in the supply and marketing channels. The production line of the industry, especially the imported production line, is accustomed to imported materials, lacking the power to switch to domestically produced new materials; Shanghai is in short supply, high operating costs, non-high-tech content, high value-added products, and it is difficult to compete with other places.
In this regard, I believe that it is very important to improve the scientific research system. This requires the universities, the Institute of Chinese Academy of Sciences, the local industrial research institutes, and the enterprise technology centers to perform their respective roles and cooperate with each other; theoretical exploration and applied research should adopt different modes of operation: the former is mainly for research costs. Relying on government support; the latter builds a close combination of production, learning, research, and use, and the funds are mainly from enterprises.
