At present, in order to cope with the fierce market competition, home appliance enterprises have turned to characteristic management, and children's home appliances have also become popular. The related products are endless: children's refrigerators, children's washing machines, children's TV sets, etc., and market sales are gradually heating up. But Du Junbao, deputy director of Pediatrics at Peking University First Hospital, pointed out that although manufacturers are very popular in promoting the fun of children's home appliances, they are not essential for children's growth, and for many home appliances, children should be properly kept away. Especially in children's rooms, it is not appropriate to place too many appliances. Because the home appliances are too concentrated, the electromagnetic radiation in the room will increase sharply. Electromagnetic radiation is not only bad for children's growth and development, but also causes diseases such as asthma and leukemia. Studies have confirmed that children are sensitive to electromagnetic radiation. Electromagnetic radiation increases the risk of cancer in children. Electromagnetic radiation may also cause mental disabilities in children. Long-term exposure to high electromagnetic radiation can cause changes in blood, lymph and cellular protoplasts. , causing the occurrence of childhood leukemia. X-rays from TVs and video game consoles can reach 8-12 millirems per hour. When it comes into contact with children's bodies, it will penetrate certain cells and cause cell degeneration and tissue damage, resulting in a group of muscle pain in the eyes. A disorder in which mental disorders are the main symptom. Therefore, children should not watch TV for too long, and they should be active every two hours. The distance between watching TV should also be more than 2 meters. In addition, the volume of household appliances should be controlled below 60 decibels, otherwise it will lead to children's hearing loss, affecting children's intelligence, personality, etc., resulting in lack of concentration, misconduct, lack of expression, lack of patience and knowledge. Desire, slow learning, curiosity, etc. In order to avoid the above hazards, not only should the home appliances in the room be placed scientifically, so that children should be kept away from certain electrical appliances as much as possible, and children should be given more fresh vegetables, fruits and animal liver, lean meat, egg yolk, millet, and legumes. Etc. to ensure your child's health. TV set TV sets are available in almost every household and are the most exposed to children. Although TV shows can bring different experiences to children and learn more, the most obvious thing to watch TV for a long time is to affect children's vision. Some children always like to watch TV at close range, and their eyes are not relieved, causing myopia. On the other hand, television also produces radiation when it is working, especially in the range of 1 meter from the TV. Long-term watching TV will also produce "TV disease", including decreased vision, cervical spondylosis, low back pain, and indigestion. In addition, children have long been addicted to television, reducing outdoor activities and communication activities, and also cause psychological isolation and physical weakness. Microwave oven Microwave ovens are commonly used in people's lives. The frequency of microwaves in household microwave ovens is 2,450 MHz. Although such microwaves cannot penetrate the internal organs and tissues of the human body, they can cause heat to the skin and body tissues. If it is exposed to radiation for a long time, It can also cause symptoms such as stress, headache, depression and insomnia. So try not to let children touch the microwave oven, especially when the microwave oven is running, you can't let the children stand nearby, and don't open the microwave oven to prevent electromagnetic waves from leaking. Induction cooker The induction cooker is accepted because it is convenient and fast, but when the induction cooker is working, the strength of the closed magnetic field generated at the edge of the induction cooker is 160 milligauss. Although the strength is not very large, it is still for children in the growing period. There are certain hazards. In addition, a large amount of heat is generated when the induction cooker is working. If the child is exposed, there is a danger of being burnt. Therefore, the induction cooker must be placed as far as possible out of reach of children.
EDM (electrical discharge machining), is a
manufacturing process used to obtain a specific desired shape in metal by
applying electrical discharges(sparks),When it comes to using electrical
discharge machining, the water serves as a key component. To get the best
performance from an Edm Machine, the water must be kept as clean as possible.
During the EDM process, some of the metal goes into the water as small
particles. The water is filtered and deionized(demineralized) in order to
remove those metal atoms. Deionized water helps to promote a higher metal
removal rate and enhances the machine`s capacity to deliver a more precise cut.
So the EDM water filter is very important component for EDM water filtration
system.
