In accordance with the provisions of OECD and technology intensive situation, automobile, machinery, nonferrous metallurgy and chemical industry belong to the mid-technology industry.
The tech industry is specific area according to its high content of research and development. It includes aerospace, information industry copper chromite (CC) and pharmaceutical industry. The fine chemical industry is a branch of chemical industry generally in technical areas. It has been identified as fine chemicals, high performance new materials, pharmaceutical, biological and chemical in high-tech areas. The 21st century is the era of knowledge economy. A new technological revolution of the three cutting-edge science based bio-engineering, information science and new materials science is bound to have a significant impact on the chemical industry. The trend of development of traditional industries such as fine chemicals will increase the technical knowledge intensive and high-tech complementary.
The so-called nanotechnology is the motion and interaction of material composition study funded by the size between 0.1 to 100 nm system, as well as the practical application of technical problems of science and technology. Nanotechnology is an important part of science and triphenyl bismuth technology in the 21st century industrial revolution, it is a high degree of cross-physics, chemistry, biology, materials science, electronics and other disciplines of integrated disciplines, including the basis of the main line of observation, analysis and research science, and nano-engineering and processing, the main line of science. It can not be denied that the nanoscience and nanotechnology is a financial frontiers of science and high-tech in one complete system. Nanotechnology, including nano electronics, nano-machines and nano-materials technology. As the 20th century, microelectronics and computer technology, nanotechnology is one of the new technologies of the 21st century. Its research and application will once again bring a technological revolution.
Because nanomaterials have the characteristics of the quantum size effect, small size effect, surface effect and macroscopic quantum tunneling effects. It makes the thermal magnetic nanoparticles, the light sensitive properties, surface stability, diffusion and sintering properties, and mechanical properties superior to ordinary particles. So nano-materials have a very wide range of applications in fine chemicals. It is in the following areas: Nano polymers for the manufacture of high strength to weight ratio of the foam, transparent insulating materials, laser-doped transparent foam, fiber strength, high surface area adsorbents, ion exchange resin, filtration, gels, and porous electrodes. Nano household chemicals and cosmetics, nano pigment, nano sensitive film, nano-fine chemical materials will bring us to the colorful world. Company research department study with pigment of new nano-molecular dye powder is expected to color images will bring a revolutionary change. Foreign nanomaterials have used nano-SiO2 as additive to adhesives and sealants, the tightness of the bonding effect of the adhesives and sealants have greatly improved. The 10-hydroxydecanoic acid mechanism is coated with a layer of organic material to the surface of SiO2 nanoparticles, hydrophilic, and adds it to the sealant quickly to form a silica structure, nano-SiO2 formation of network structure, limiting colloidal flow and solid accelerated to improve the bonding effect due to small particle size, increase the tightness of the rubber. Add nano-SiO2 can exponentially increase its anti-aging properties, finish and strength in various types of coatings, paint quality and grades of natural upgrade. Nano SiO2 is an anti-ultraviolet radiation materials (i.e., aging), combined with its extremely small particles of large surface area quickly in the paint is dry to form a network structure, while increasing the strength and finish of the paint.Source:http://www.mhcfm.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
