Microwave radiation is widely used in fields of navigation, tracking, communication, food baking, and medical treatment, etc. Microwave generator and radar can have varying degrees affect on the nearby and farther objects. Shielding of electronic devices can prevent the interference of external electromagnetic waves, to ensure the normal operation of the equipment and workers' health. Therefore, it is necessary to implement anti-radiation packaging for some articles.

 

The key of radiation shielding package is to select the appropriate packaging materials. Electromagnetic sensitive products needed to be protected in the process of production, storage, transportation, sales, which requires the radiation of electromagnetic shielding packaging. Tungsten alloy, radiation shielding materials, can shield electromagnetic radiation and optical radiation, X radiation, gamma radiation, and neutron radiation, etc. It also uses tungsten alloy fiber material and Composite material added with rare earth alloy to make radiation shielding package

 

The radiation shielding properties of tungsten alloy shielding materials are closely related to the density of materials. Higher density means better X-ray absorption ability and ray shielding ability. As tungsten alloy material has higher density, it has better radiation shielding and it can reduce the volume of packaging.

 

For electronics, high performance shielding packaging materials can not completely reliable and effectively eliminate the impact of electromagnetic radiation on the performance of the products. It also needs to consider the protection and electromagnetic shielding in the circuit structure design of electronic products. Because traditional outer packaging materials can not completely shield electromagnetic radiation, now people generally use electromagnetic radiation shielding package, which includes the commonly used radiation shielding packaging metal materials and conductive composite plastic shielding materials. Put the granular tungsten alloy fine fibers to the thermoplastic for injection molding, which can form a variety of shielding packaging materials and containers, such as molded conductive composite plastic, conductive composite films, and conductive surface treatment materials, etc.
