There are many varieties of magnet materials, which are widely used in permanent magnets, rare earth permanent magnets, soft ferrites, amorphous soft magnetic materials, microwave ferrite equipment, magnet special equipment and other fields, including permanent magnets. Data, soft magnetic data, special magnetic data, letter magnetic data, etc. Invented a very high value for the development of the Chinese economy.
We usually need a lot of permanent magnetic components, ferrite soft magnetic equipment and ferrite microwave equipment for mobile phone permanent magnet ferrites used for communication. Some large machines used in the industry also require a lot of high-skilled magnetic cores and other components. At present, the video phone that is rapidly developing also requires a lot of magnet components.
Take the lighting industry as an example, the output value of LED lamps has increased in recent years, and the demand for ferrite soft magnetic materials has been a lot.
In addition, magnet materials are also in great demand in occupations such as color TVs, electric bicycles, lighting equipment, electric toys, vacuum cleaners, and appliances.
According to statistics, the automotive industry needs a lot of magnet data from magnet manufacturers every year.
In recent years, the IT profession has expanded rapidly. Computer accessories such as CD-ROM drives, DVD-ROM drives, hard disk drives, monitors, multimedia speakers, printers, and notebook computers also require a lot of ferrite soft magnetic, neodymium iron boron and other components.
The application scope of magnet data is very wide, which is the foundation of the data profession. With the rapid rise of China's electronics and electrical industries, China has become the world's largest producer and consumer of magnet materials.
Relevant scientists pointed out that NdFeB is a kind of permanent magnet material with excellent performance, which is widely used in electronics, communication and other fields. The materials are rich in about 30% of rare earth elements (with about 90% neodymium, and others are terbium, dysprosium, etc.), and some are rich in 2% to 3% of cobalt. The rare earth elements in NdFeB resources are extremely versatile and have an important impact on social development and economic construction. However, due to the backward production process, about 20% of NdFeB waste will be generated during the production and use of NdFeB. The failure to recover and use not only causes the waste of raw materials and resources, but also causes serious environmental pollution.
With the continuous development of industrial technology, all kinds of original materials are being consumed rapidly. The characteristics and common sense of special-shaped magnets, so we probably recover and use the discarded NdFeB materials, which not only avoids the abuse of power, but also maintains our dependence. To survive in the environment,
Professor of Environmental Protection pointed out that the rare earth elements recovered from NdFeB waste can produce neodymium oxide, dysprosium oxide, cobalt oxide and terbium oxide. Metal neodymium is mainly used as additives for neodymium iron boron permanent magnet materials, oxygen storage materials, central alloys and pyrophoric alloys. Neodymium oxide is mainly used in laser materials, ceramic color glazes, special glass colorants and jewelry colorants.
Professor pointed out that the recovery and utilization of industrial waste is an important way to develop the reincarnation economy; when the recovery and utilization of waste is carried out, it is also necessary to make good use of the original data resources of the country.
