The principle of EMI shielding clothing is based on the "absorption" principle of electromagnetic interference. In the electromagnetic shielding clothing, iron fiber or copper wire lines can absorb and scatter electromagnetic waves, so that its energy is weakened, so as to achieve the purpose of shielding electromagnetic interference.
It should be noted that electromagnetic shielding clothing does not completely block electromagnetic radiation, but can effectively reduce its intensity. In addition, electromagnetic shielding clothing usually can only block low-frequency electromagnetic radiation, high-frequency electromagnetic radiation blocking effect is poor.
Electromagnetic shielding clothing is widely used, common applications include medical, military, aerospace, electronics industry and other fields.
In the medical field, electromagnetic shielding clothing is commonly used to protect medical personnel in the use of electromagnetic equipment may be subject to electromagnetic interference. For example, the use of electromagnetic shielding clothing in the operating room can effectively reduce the impact of electromagnetic interference on patients and medical personnel.
In the military field, electromagnetic shielding clothing is often used to protect soldiers in the use of electronic equipment may be subject to electromagnetic interference. For example, in the use of navigation equipment, electromagnetic shielding clothing can prevent electromagnetic interference caused by navigation equipment errors.
In the aerospace field, electromagnetic shielding clothing is often used to protect pilots in the use of electronic equipment may be subject to electromagnetic interference. For example, when piloting an airplane, an EMI shielded suit can prevent EMI from causing errors in the flight control system.
In the electronics industry, electromagnetic shielding clothing is often used to protect electronic equipment in the use of electromagnetic interference may be subjected to. For example, in the research and development, production, testing and other processes of electronic equipment, can use electromagnetic shielding clothing to reduce the impact of electromagnetic interference on electronic equipment.
In addition, electromagnetic shielding clothing can also be used to protect individuals from electromagnetic radiation, especially in the use of cell phones, computers, WIFI equipment, some people will find discomfort or headache, which may be caused by electromagnetic radiation. At this time, the use of electromagnetic shielding clothing can effectively reduce the impact of electromagnetic radiation on personal health.
But it should be noted that the electromagnetic shielding clothing is not everything, in the electromagnetic interference intensity is very high environment or high-frequency electromagnetic radiation, electromagnetic shielding clothing blocking effect will be limited.
In addition, the choice of electromagnetic shielding clothing, but also need to pay attention to the quality of electromagnetic shielding clothing, to ensure that the electromagnetic shielding clothing material and structure are in line with the requirements.
