Hengdian Kim Dae-magnetic NdFeB magnet factory ----- What precautions NdFeB magnets because of superior magnetic attraction, in the course of the workplace should ensure a clean install and use, otherwise easily absorbed iron attract objects thereto debris, nails and other speaker magnet size, too small particles of iron powder will affect its use; Material Features NdFeB magnets are hard and brittle, and its suction up to more than 600 times its own weight easily pull collision damage. Procedure for small size magnets should be taken to avoid damage bump, magnets and more for large sizes to note that personal safety and protection. Hengdian Kim aka magnet magnet magnetic Factory ---- refers to the presence of a magnetic field around the object or material and their own internal, is divided into two major categories of natural and man-made. Artificial magnets usually made of a metal alloy, having a ferromagnetic. Can be divided into "non-permanent magnet" and "non-permanent magnet" Buying speaker magnet, or "magnetic hard" and "soft." Natural magnet main ingredients: iron oxide, the chemical formula Fe3O4, often referred to as "magnetic iron oxide." Having a magnetic black crystals. Ferrous oxide and iron oxide compounds can be regarded as. Because the iron oxide crystals in the presence of two different valence states of ions, one third of Fe2 +, two-thirds of Fe3 +, is a complex compound. It is insoluble in water, it can not react with water. Reaction speaker magnet accessories with acid, alkali-insoluble. The main system for high-temperature magnetic primer and topcoat, magnetic materials for the electronics industry, but also for rust in the construction industry. Speaker magnet manufacturers, large magnetic plant proverbial gold (certified), Taizhou speaker magnet is provided by a large magnetic Hengdian gold plant. Hengdian Kim Dae-magnetic Factory (www.jjdct.cn) is an industry leader in Jinhua, Zhejiang, electronics, electrical products manufacturing equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In the Kim Dae-magnetic plant leadership with the staff warmly welcome all inquiries negotiations to create a large magnetic gold plant a better future.
