During the "10th Five-Year Plan" period, 112 projects in Fujian were included in the national Torch Program and a number of scientific and technological achievements with independent intellectual property rights were obtained in the fields of chemical engineering, new materials, biotechnology and environmental protection. The chromium-free high-variation fertilizer catalyst developed in Fujian Province has completely solved the worldwide problems of chromium pollution in high-variation catalysts in the past 100 years; "B121 type chromium-free carbon monoxide high-humidity shift catalyst" and "development of solid superacid photocatalysts and their industries "Applied technology development" won the first prize of national scientific and technological progress; the research results of catalytic distillation of methyl acetate have reached the international advanced level, and successfully achieved industrialization; "engineerable preparation technology of high-performance silicon carbide fiber" has been a breakthrough The key link, entering the pilot phase, is expected to break the blockade imposed on our country by the developed countries. In addition, Fujian's research achievements in the field of inorganic nonlinear optical crystal materials are at the leading position in the world; the design and synthesis of optically functional nano-ceramics, nano-optical glass ceramics, and nano-molecular devices, and the capture of carbon-50 research have entered the international frontier. "Research on the synthesis, structure and properties of new inorganic polymer materials" won the second prize of the National Natural Science Award; has the following advantages in the fields of bioethanol production, hydrogen production, biodiesel research and development, industrialization, and biocatalytic synthesis. Good research foundation. By the end of 2005, Fujian had identified 811 high-tech enterprises and 64 national key high-tech companies in the Torch Plan, playing an important role in the development of high-tech and industries.
PP Resin
Polypropylene is a polymer formed by addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. The chemical formula is (C3H6)n, the density is 0.89~0.91g/cm3, it is flammable, the melting point is 189℃, it softens at about 155℃, and the use temperature range is -30~140℃. It is resistant to corrosion by acids, alkalis, salt solutions and a variety of organic solvents below 80°C, and can be decomposed under high temperature and oxidation. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc. It is also used in food and pharmaceutical packaging.
