Tungsten Anti Radiation Fiber

With the economic and social development, nuclear technology has been widely used in the fields of medical, nuclear industry and national defense, has brought enormous economic benefits and social benefits at the same time, the nuclear radiation of human exposure to a variety of opportunities, potential threat to human health and environmental safety. 

Radiation protection materials and equipment is the key to ensure the safety and safety of workers in the radiation sites, and is also an effective way to deal with nuclear emergency. It is an important guarantee for radiation safety protection in military and civilian areas.

As we all know, the clothing and gloves woven by polyamide (nylon), polyethylene terephthalate and polyacrylonitrile and other polymer fibers have excellent air permeability, but their radiation protection effect is weak. It has been found and proved that inorganic particles such as lead tungstate and bismuth tungstate have excellent radiation protection properties, especially nano size structure tungsten materials. The same quality nanoparticles have higher radiation protection effect on rays. If we can combine them well, realize polymer composite fiber processing technology and further realize automatic weaving of fiber yarn, it will greatly enhance its wearability and expand its application area.

In recent years, China's manufacturing technology has also made great progress, and has begun to manufacture similar tungsten fiber anti radiation clothing. Researchers have published related technologies of tungsten metal radiation protection clothing.

1.Inorganic particles, bismuth tungstate, or lead tungstate, which have radiation protection function, are activated, filtered, washed and dried in turn, then transferred to the reactor and protected by inert gas.

2.In situ polymerization of inorganic particles with radiation protection function was used to prepare inorganic particle graft. The inorganic particle grafts were prepared by grafting inorganic particles of polyacrylonitrile, polyethylene terephthalate, and polyamide.

3.The grafting of inorganic particles from step 2 and fiber grade polyacrylonitrile are blended and spinning, that is, the fabric of anti radiation fiber is prepared.

A polymer composite fiber with radiation protection function is formed by melt spinning, which has excellent nuclear radiation protection performance. According to the needs of different radiation environments, polymer composite fibers with gamma, neutron and neutron gamma protection effects can be selected respectively. The fabric or products made of the radiation protective polymer composite fiber have good flexibility, air permeability and comfort. This radiation protective polymer composite fiber can be used in the preparation of protective equipment such as nuclear radiation protective clothing and flexible nuclear radiation protective screen.
