Detailed Product Description: | First, silver is an expensive metal, with strong reflection ability and good thermal conductivity, electrical conductivity, are widely used in photography, machinery, electronics, equipment, instruments, jewelry, tableware and other industries. The current state purchase price 1,600 yuan / kg, the next significant increase in the industrial use of silver, silver in short supply, prices will continue to rise. Second, people usually only know that gold and silver extracted from the ore, but the studio did not know the country, hospital radiology department, printing, electroplating plants, mirror plant, Vacuum Flask Factory, radio, electric switch plant, drug testing The laboratory, photographic materials, plant and other units daily discharge of waste water, wastes contain large amounts of silver, the "three wastes" means: photographic fixer waste, waste silver solution, semiconductor manufacturing pipe waste water treatment, waste Semiconductor components, electrical connectors, silver trim, mirror the industry and other waste. Source of raw materials: the country Zhaoxiang Guan, hospital radiology department, printing, electroplating factories, radio factory, electrical switch factory, semiconductor components factory, mirror plant, waste recycling, and other units to contact to buy. Third, the wastewater recycling of silver, in the past by electrolysis, but the equipment investment, high cost, long time, and only 70% recovery of silver; after the NA method used, although 90% of the silver recovered, but the operation of toxic, impact on human health, investment in equipment up on the yuan. My unit a unique personal investment in the two-step method for rapid extraction of silver and efficient new technology, it is silver extracted by national technical supervision departments, the state acquisition criteria. Half an hour to make all the silver in waste water, by hand, without special equipment, just a coal stove and several chemicals and have the water of urban and rural waste, less investment (100-200 yuan), a person is operational, non-toxic, non-polluting, non-radioactive, chemical refining required pharmaceutical companies in cities and counties or chemical stores are sold. Fourth, the use of simple tools to invest 200, 10-15 square meters of space, (which can be detected by measurement of silver paper with silver concentration), according to state procurement price of 1,600 yuan / kg, a value of 1080-1600 dollars, 100 kilograms of waste water of 300 dollars, chemical raw materials and other costs to be 50-70 million, comprehensive cost 350-370 dollars, sufficient raw materials can process 200 kg per person per day waste water, so profits are quite substantial. Technology Transfer: face to face with 580 teaching materials and CD-ROM and a complimentary silver test paper, correspondence 280 (express mail) Contact Patrick handsets Address: Shandong Province, Shenzhen Road 61, Jiaonan URL QQ 0 |
