Recovery processing method for waste magnesium alloy mobile phones and notebook computer shells

Abstract

The invention discloses a recovery processing method for waste magnesium alloy mobile phones and notebook computer shells. Stringent selection and isolated air heating are adopted, organic matters inthe waste magnesium alloy mobile phones and the notebook computer shells are recovered through a creaking method and high-temperature cracking conversion is carried out to obtained creaking oil and creaking gas, so that the resource utilization is realized, meanwhile, iron, copper, stainless steel, aluminum and flux waste residues in the waste magnesium alloy mobile phones and the notebook computer shells are recovered, and classified recycling is carried out to achieve the purposes of environmental friendliness, full utilization of resources and good economic benefits in the processing process. According to the recovery processing method for the waste magnesium alloy mobile phones and the notebook computer shells, the recycling of the waste electronic products can be realized, plastic canbe effectively recycled, meanwhile, nonferrous metals in a circuit board can be effectively separated and reused, the pollution of the waste electronic products to the environment is avoided, and therecovery method of the waste electronic products has the advantages of reasonable design, safety and practicability and can be widely popularized and used.

Description

Technical field [0001] The invention belongs to the technical field of recycling and utilization of waste resources of electronic products, and relates to a recycling treatment method for waste magnesium alloy mobile phones and notebook computer casings. Background technique [0002] With the rapid development of modern science and technology, it has entered a rapidly changing information and network era. All kinds of advanced communication equipment are constantly being updated and updated. Due to the excellent electronic wave shielding performance of metallic magnesium and magnesium alloy, they are widely used in electronic communication equipment. Especially the shells of electronic communication mobile phones, notebook computers and photographic equipment and instrument panels. More importantly, the shells of mobile phones and laptops. Due to the rapid replacement of these communication devices, a large number of obsolete products are abandoned, the more expensive movements ...

AI Technical Summary

Problems solved by technology

What's more important is the case of mobile phones and laptops. Due to the rapid replacement of these communication devices, a large number of obsolete products have been abandoned. Emissions, and some defective products generated during the processing of mobile phones and notebooks are discharged together, because this part of electronic waste is accompanied by some difficult-to-handle rubber, plastics, paints, coatings, and even some metals such as stainless steel, aluminum, copper, etc. Materials, as well as a very small amount of precious metal gold are not recycled and utilized, which is neither environmentally friendly nor wasteful of resources; and due to the complexity of the composition, the simple roasting process not only causes environmental pollution, but also costs too much to deal with, making it difficult to pass the economic level. Therefore, these electronic waste A large amount of discharge and accumulation has become a difficult problem for the society

[0003] In addition, due to the small size of these e-waste, the size of a single piece, and a large number of the above-mentioned complex components, many factors have caused difficulties in disposal
