Da Xing waste recycling, South gilded recovery, gold recovery recycling scrap materials provided by Da Xing. We are Dongguan City of scrap material recycling companies (www.dxhphs.com) located at: Dongguan specializes in: scrap metal recycling, waste plastic recycling, e-waste recycling, industrial waste recycling, green building professionals pointed out that e-waste dismantling Xie, burning pollution mainly heavy metals, volatile organic compounds and particulate matter. Dissemination in the air, such as volatile organic compounds and particulate matter, will have a serious impact on the human body. Professionals believe that e-waste is hazardous and resource characteristics coexist, does not regulate the activities will lead to the dismantling of large quantities of pollutants released into the environment, a large number of studies have demonstrated the e-waste dismantling regional environmental pollution. For example, in the initial and depth dismantling e-waste, the absence of effective measures to protect South City gilded recycling, metal fittings, ray tubes, circuit boards will directly lead the human kidney and nervous system damage; batteries, circuit boards Mercury is a direct result of lung disease and cancer crisis; washing machines, refrigerators and other plastic chassis, it will directly interfere with the endocrine and fetal gestation, increase digestive and lymphatic system cancer risk. Under the impetus of "waste electrical and electronic product recycling regulations" and supporting the full implementation of the policy, China's e-waste recycling industry has been rapid development. Whether gilded recovery in the management system or resource recycling, the field energy conservation, pollution prevention have achieved significant results. China Household Electric Appliance Research Institute, Institute of Electrical Project Engineer single-cycle technology Hemingway said that the rapid development of e-waste recycling industry, and promote the development of circular economy, while promoting extended producer responsibility system in our country in the process of building. Metal recovery techniques substance regeneration Institute of Applied electrolytic silver design their own equipment to graphite plate as the cathode, the anode is stainless steel drum, the drum has many pores. Sodium citrate and sodium sulfite as the electrolyte, silver pieces from the first end of the drum into the Shanwei gilt recovered from the drum trailing sent. Silver plating on the surface into the electrolyte Shenzhen gilded recovery, plating the substrate is completely non-destructive to return to the new plating applications. Silver recoveries of 97-98%, silver purity of 99.9%. Scrap silver - zinc battery recycling scrap silver-zinc battery applications containing silver 52.55%, 42.7% zinc. Zinc anode, silver oxide positive electrode coated on the copper network backbone. Regeneration Institute of Applied substance use sulfuric acid to break up dip zinc and copper, silver indirect melting ingots. Participate in dilute sulfuric acid leaching of copper oxidant, zinc consumption was concentrated zinc sulfate crystals, copper consumption was concentrated copper sulphate crystals. Zinc recovery> 98% and silver recoveries of 98% silver bullion purity> 99%.
