The chemical characteristics of 4
With halogen, oxygen can direct reaction, generate the corresponding halide or oxide.
5 purposes
Used in the manufacture of thermal process phosphoric acid, reach the chlorine phosphorus, phosphorus oxychloride, phosphorus compounds such as phosphorus pentasulfide and for manufacturing trichlorfon, ammonium phosphate, insecticidal narrowing, dichlorvos and so on raw material of organophosphorus pesticide and the exterminator. White phosphorus (poisonous) (easy system)
6 prevention
Jobs should be worn when operating labor protection, workshop is equipped with 2-5% copper sulfate solution, the production system should be sealed, the environment should be ventilated, posts should be filled with a clear water reserviors, packaging yellow phosphorus when operating in strict accordance with the procedures.
7 the emergency response
Yellow phosphorus burns should immediately put out with water, prevent splashing; Phosphorus burn skin, immediately immersed in water, soaking with 2% sodium bicarbonate solution first, and then rinse it burns, with 1-2% CUS04 solution after the site emergency treatment, rushed to the nearby hospital treatment; Oral yellow phosphorus poisoning immediately with 0.2% copper sulfate gastric lavage, taboo fat food and milk at the same time.
8 fire control measures
Yellow phosphorus packaging post valves shall be equipped with water and fire control valve, a yellow phosphorus burns water to rush shoot, prevent splash, wait for after the fire, burning point must be clean, prevent burning again.
9 warehouse storage
Iron drum costumes, barrel body should not leak, yellow phosphorus submerged in water. Should with inflammable, explosive, oxidant, sulphur, element, strong acid and oxygen isolation, away from heat and flame. Net weight 200 kg (+ / - 1 kg.
10 transportation editor
Steel drum packaging should not leak, to prevent shock, friction, fight drums upside down, it is strictly prohibited inside the steel drum water shortage. It is strictly prohibited and other conventional transport goods.
Yellow phosphorus is one of the most important basic industrial raw materials, mainly used in chemical, pesticide, and other fields. At present, the production of the highest in the world, there are hundreds of yellow phosphorus plants, production device are mainly distributed in four provinces of yunnan, guizhou, sichuan, hunan, cloud, expensive, and sichuan provinces yellow phosphorus production capacity of more than 80% of the country. Because of the yellow phosphorus production will consume large amounts of energy, and brings great impact on the surrounding environment, belong to high energy consumption, high pollution industry, so the developed countries will yellow phosphorus production is transferred to developing countries.
Yellow phosphorus production technology is relatively simple, the phosphate rock, silica and coke according to certain proportion and granularity in the electric furnace, in more than 1000 degrees high temperature decomposition, reduction reaction, phosphorus steam is cooled with furnace dust, product after rinsing, high temperature furnace slag is directly from the eduction in electric furnace.
Our country mainly yellow phosphorus factory: xiangfan projecting phosphorus chemical industry co., LTD (www.gaolongchem.cn), guiyang ho kit industry and trade, yunnan minmetals xinhua, jiaxing jia logistics, danjiangkou phosphorus chemical industry, sino-german phosphorus industry, gezhouba phosphorous chemical industry, hubei JingXiang chemical industry group co., LTD., hubei xingfa, sichuan linchen group, sichuan and electroforming, Huang Linchang 'mountain, anda phosphorus chemical industry, kaiyang phosphate phosphorus chemical industry city, map of xifeng phosphate rock, guizhou KaiLin, white horse Huang Linchang, qian can days.
Exploitation of yellow phosphorus as the raw material of fine phosphate products: phosphate industry is a competitive industry, who won the market, who will win the initiative. Phosphate is a kind of many products a variety of purposes, and in practice can continuously develop new USES. If some products according to the amount of impurity content, feed grade, food grade and electronic level, with the improvement of product level, efficiency can be greatly improved, some even double. Phosphate products belong to the category of fine chemical industry, its production technology confidentiality is very strong, although our country has made some achievements in this field, but also has the very big disparity compared with abroad, there are a lot of products to be exploited, and many fields are blank. In the future in essence and deep phosphate product technology, high added value product development technology. Such as yellow phosphorus fine products abroad, yellow phosphorus using phosphine after refining production of yellow phosphorus is mainly used in electronic industry, its sale price is ten times the current market price of yellow phosphorus in China. The development of fine phosphorus chemical industry in our country is relatively backward, less product variety, quality specification is not complete, standard is relatively low, such as variety selection, technology development, application research is very weak, for different industries, different USES of different specifications products are lack, used in electronic, aerospace, precision machinery, daily chemical, petrochemical, environmental protection coating and functional materials.
