2, electronic waste
The main use of electric current, electromagnetic field work of the equipment are called electronic equipment; waste electronic equipment are electronic waste.
E-waste mainly includes refrigerators, air conditioners, washing machines, televisions and other household appliances and computers and other communications electronics and other obsolete products. E-waste is commonly known as "e-waste".
There are many types of e-waste, can be roughly divided into two categories: one is the material contained in a relatively simple, less harmful to the environment of waste electronic products, such as refrigerators, washing machines, air-conditioning and other household appliances, as well as medical, scientific research appliances, etc., the dismantling and processing of such products is relatively simple; the other is the material contained in a more complex, more environmentally hazardous waste electronic products, such as computers, The other category is the more complex materials contained in the waste electronic products more harmful to the environment, such as computers, TV tubes within the lead, computer components containing arsenic, mercury and other harmful substances.

One, the current situation of the application of electronic products
With the progress of society, science and technology continues to develop, electronic products to bring convenience to our daily life, cell phones, computers, etc., up to sixty or seventy years old, down to six or seven-year-old children, are using cell phones, computers. Cell phones and computers bring us convenience, but also bring harm, now the phone to bring us a lot of convenience, for example: in Taobao to buy things, search for their own needs on the network, and now WeChat and Alipay to pay, do not have to be afraid of losing money, as well as don't know the way to the cell phone can be used to navigate the cell phone, cell phone positioning, **** enjoy the location, making information, etc., for us to bring great convenience, but the mobile phone to bring us the convenience, but also to bring us the harm. Convenience, but cell phones bring us a lot of harm, for example: so that nowadays children have poor self-control, easy to indulge in online games, it is difficult to control themselves, resulting in their own mind to study, and even may be because of the cell phone and parents fight, so that parents are very helpless, which is not conducive to the growth of children for parents, because to get a cell phone, many children do not go to the sports, addicted to the game, resulting in bad eyes, so that the child's physical coordination decreased, and even the child's physical coordination, and even the child's physical coordination decreased, and the child's physical coordination decreased. Children's physical coordination decline, and even those in the network of violence and pornography, etc., will affect the children's physical and mental health, these bad things make parents very helpless, in short, electronic products are like a double-edged sword, the use of good, to benefit the people, the use of bad, harmful to the people, if the parents can effectively control their own children, I believe that the benefits of the development of electronic products outweighs the drawbacks, electronic products to promote the socio-economic development, make our lives more convenient, and make us live more conveniently. The development of electronic products promotes the development of social economy, makes our life more convenient, and makes a great contribution to the development of social economy.
