Technology R&D to support raw material resources for protection
At present, Chengdu-Chongqing Economic Zone and Tianfu New District in planning and construction have brought significant opportunities for the development of related industries. Chengdu, with its unique advantages in the development of new materials industry, is taking the power of the whole city and taking multiple measures to promote the leap-forward development of new material industries. . According to the goals set by the Chengdu government, by 2015, the sales revenue of the new materials industry will exceed 100 billion yuan, and the industrial added value will exceed 25 billion yuan; 3 companies with annual sales revenue exceeding 10 billion yuan will be cultivated, and 4 companies with 5 billion yuan will be cultivated. , 8 billion yuan of enterprises; the domestic market share of high-performance fiber and composite materials, electronic information materials, new chemical materials, new energy materials, etc., has obviously increased, and the country’s leading national new material industrial base has been basically established in the western region. .
There are 86 new material companies above the scale in Chengdu's new materials industry, and polyphenylene sulfide resin and fiber preparation technologies have reached the leading domestic level. Techniques for osteoinductive materials, nano-hydroxyapatite, titanium apatite coating materials, etc. In the forefront of the country, the main products are high-performance fiber and its composite materials, rail transportation materials, electronic information materials, new chemical materials, silicon lithium materials.
Liu Chao, member of the Standing Committee of the Chengdu Municipal Committee, said that Chengdu's development of new materials industry has unique advantages: First, new materials have strong research and development capabilities. Sichuan University, Southwest Jiaotong University, University of Electronic Science and Technology, and Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences all have institutes and key laboratories closely related to materials science research, as well as provincial and municipal enterprise technology centers and engineering and technology centers. The sustainable and healthy development of the material industry provides technical support. Second, raw materials have obvious advantages. The Sichuan Petrochemical Base in Pengzhou, Chengdu, will be put into operation in 2012. It can develop polyester and synthetic resin materials for Chengdu, and provide benzene, para-xylene, polyethylene and polypropylene raw materials; the annual production capacity of solar polysilicon will reach 10,000 tons in 2012; Chengdu And the surrounding areas are rich in resources, with the rare earth reserves and output ranking second in the country.
According to the briefing, Chengdu City has borrowed the Dongfeng of the Chengdu-Chongqing Economic Zone and the Tianfu New District, and has determined the strategy for the development of a new material industry. Taking the lead in the construction of major projects and the cultivation of leading enterprises, taking breakthroughs in key core technologies and process development and application, building professional parks and service platforms, strengthening government guidance and policy support as a guarantee, and striving to become distinctive features and advantages. Prominent national new material industry base. The layout of the six-point nuclear industrial structure is: the new material industrial functional zone focuses on the development of high-performance fiber and composite materials, electronic information materials, rail transportation materials, and other new materials such as new energy, chemical industry, and biomedical, to create R&D and manufacturing. Core areas of new material industry development integrated with trade; Qingbaijiang Industrial Development Zone focuses on the development of high-performance fibers and composite materials; Chengdu Hi-tech Development Zone focuses on the development of electronic information materials and new biomedical materials; Xihang Port Development Zone focuses on the development of PPS. Fiber and new energy materials; Pengzhou Industrial Development Zone and Chengbei Industrial Park focus on polyester and synthetic resin materials.
At the same time, Chengdu proposes to consolidate and upgrade new chemical materials, enlarge and strengthen high-performance fibers and composite materials and electronic information materials, cultivate and develop new energy materials and new biomedical materials, as well as high-performance rail transit materials, and new types of materials. Other new materials, including building materials.
Liu Chao pointed out that in recent years, the pace of new-type industrialization and new-type urbanization in Chengdu has been accelerating, and the construction of infrastructure such as subways and road networks has entered a period of rapid development. The development of industrial clusters such as electronic information, mechanical automobiles, metallurgy and building materials, and aerospace has achieved certain scale and comparative advantages. New energy vehicles, energy conservation and environmental protection industries have been rapidly developed. All these provide a vast space for the development of the new material industry.
The reporter learned that Chengdu has introduced a series of policies to support the development of the new material industry. It has strengthened corporate support from corporate finance, technological breakthroughs, transformation of achievements, market development, etc. The current support award funds have exceeded RMB 55 million. . It also vigorously promoted industrial innovation capabilities. While actively promoting the construction of a national high-performance fiber high-tech industrialization base, it also strived for the approval of the Chengdu National New Material High-tech Industrial Base, setting up special projects for new materials and supporting key technology breakthroughs in the new materials field. The research and development of key products will be organized into the Urban New Materials Industry Research Institute and the establishment of an enterprise technology center will be strengthened.
Since the beginning of this year, the city’s new materials industry has shown good momentum of development. Data show that in the first half of the year, the new material industry completed an industrial added value of 4.889 billion yuan, up 20.9% year-on-year; sales revenue was 14 billion yuan, an increase of 21.2% over the same period of the previous year. Meanwhile, a number of major projects that were newly introduced started construction.
Oxides are compounds (and certainly pure). Its composition contains only two elements, one of which must be oxygen, and if the other is a metal element, it is called a metal oxide; If the other is not a metallic element, it is called a non-metallic oxide.
Oxides in a broad sense refer to binary compounds composed of oxygen elements and another chemical element, such as carbon dioxide (COâ‚‚), calcium oxide (CaO), carbon monoxide (CO) and so on. However, compounds formed by the combination of oxygen and more electronegating fluorine are generally referred to as fluorides rather than oxides.
(1) According to the type of another element combined with oxidation, it is divided into metal oxides and non-metallic oxides
(2) According to the bond type or component particle type, it is divided into ionic oxides and covalent oxides
Ionic oxides: oxides formed by some active metal elements such as Na2O, CaO, etc
Covalent oxides: Oxides of some metallic elements and all non-metallic elements such as MnO2, HgO, SO2, ClO2, etc
(3) According to the oxidation state of oxygen, it is divided into ordinary oxides (oxidation state of oxygen is -2), peroxides (oxidation state of oxygen is -1), superoxide (oxidation state of oxygen is -1/2) and ozonide (oxidation state of oxygen is -1/3)
(4) According to the acidity and alkalinity and whether it forms salts with water, and the salts generated are divided into acidic oxides, alkaline oxides and amphoteric oxides, neutral oxides, and complex oxides.
