Thermal decomposition poor thermal stability of certain metal compounds can be decomposed into the direct heating elemental metal. Reduction using a reducing agent elemental preparation method called reduction. Generally based on the choice of production scale, the experimental requirements, environmental protection, safety factors, sources of raw materials and price appropriate reducing agent. Preparation of elemental metal and nonmetal lively electrolysis, electrolysis can be used. For example, the electrolysis of saturated aqueous solution of NaCl prepared Hydrogen and chlorine; prepared molten salt electrolysis of metal Li, Na, Mg, Al and other metal: Take elemental oxidation method using an oxidizing agent system is called oxidation. For example, air oxidation method to extract sulfur from pyrite, sulfur vapor cooling available powdered sulfur. Preparation can also sulfur from natural gas. [1] Stamp by chemical fiber textile production process, with a continuous pattern depicts the level of sales of vinyl acetate reached China's chemical fiber industry, this is the first time in the history of Chinese stamps. Main flow rough lines and powerful, concise sketch of a representative pattern, background processing is also just right, to choose correctly, play a very good complement and contrast effect. Quiet darker background color and distinctive powerful tone with each other main figure, with a strong generalization ability and decorative effect, all stamps are not vinyl acetate borders, strengthen the continuity of the pattern, so that the entire stamp seamless. Chemical fibers 5 with printing natural or synthetic polymer compound as a raw material Jinan vinyl acetate, all the fibers obtained after chemical processing, chemical fibers collectively. Founding of New China, China has only one chemical fiber plant - Dandong Chemical Fiber Factory, with an annual 230 tons of viscose fiber. The late 1950s, China was the first time from the German Democratic Republic introduced a fiber equipment, built with an annual output of 6,000 tons of chemical fiber factory in Baoding, and have also built their own design, Nanjing, Hangzhou, and a number of rayon plant. In the 1960s, the development of China's major viscose (rayon that is), the slow development of synthetic fibers, only Maryland from abroad artificial production equipment imported from Japan VINYLON Baoding production equipment. From the beginning of the 1970s, China's chemical fiber industry entered a period of development. State investment 10 billion yuan, the introduction of four large chemical fiber production line, built Shanghai Jinshan Petrochemical Plant, Liaoyang Petrochemical Fiber Company and other large chemical fiber enterprises. After entering the 1980s, China has built a joint company Yizheng Chemical Fiber. By 1986, China has become the world's largest producer of chemical fiber output exceeded 100 million tons, ranking fourth in the world, the pace of development of chemical fiber production in the world is second to none.
