Application fields of low-frequency magnetic field shielding foils and sheets: industrial production, aerospace, petroleum exploration, medical equipment, physical research, navigation, computers, communications, automobiles, military, CRT display shielding and wall and House shielding and other applications: Magnetic shielding materials can be used to shield magnetic field interference sources to prevent the generation of electromagnetic radiation; magnetic shielding materials are used to shield sensitive components or equipment to prevent magnetic fields from interfering with the normal operation of equipment or systems. Low-frequency magnetic field interference sources: transformers, power lines, motors, reactors. Magnetic field interference phenomena: Magnetic field interference can cause serious problems in the design and use of electrical and electronic products, due to nearby radiation sources inside the system, transformers, switching equipment, power lines, etc. The generated magnetic field interference causes frequent failures of instruments, control systems, data processing equipment, communication networks, etc. Magnetic shielding material characteristics: Frequency range of magnetic field shielding: 0-100KHz Types of shielding materials GW-NETIC and GW-CO-NETIC series magnetic shielding materials have good magnetic shielding properties and can be applied in many environmental fields GW-NETIC and GW- CO-NETIC series magnetic shielding materials include foils and thin plates of different thicknesses; the foil thickness is 0.002?-0.010? (0.051-0.254mm), which can effectively shield magnetic fields and is usually used in the shielding of sensitive devices, printed circuit boards, and instruments. , signal lines, cables, etc.;
