New lead-free materials is expected to replace traditional lead-rubber protective materials

China has independent intellectual property rights of the all-new X-ray shielding lead-free composite materials, has been in protective clothing on the successful applications, and is expected to replace traditional lead-rubber protective materials.

Experts said that the lead-free composite broke through the shielding material of lead-free worldwide problem and is expected to be in our high-performance X-ray shielding material development and production applications in a leading position. As the traditional lead-rubber production in the lead oxide is not only caused environmental pollution, but also seriously endanger people's health.

As a result, how to ensure the effectiveness of radiation shielding, the realization of lead-free materials, became troubled by researchers at home and abroad is a major problem. It is understood that the Beijing University of Chemical Technology developed a new type of X-ray shielding lead-free all-composite material, the use of high-performance radiation-resistant polymer substrate, does not contain heavy metals lead, barium and other elements so as to avoid these harmful elements in the processing, use and waste In the process of disposal of harm to the human body. The material of lead than when the money reached 0.3mmPb/mm, X-ray shielding ability to lead a good, better than the United States, Europe, Japan 0.25mmPb/mm shielding material than the lead when the money; and shield in the same capacity, The lead material than 30% of light materials.

In addition, the traditional lead materials, the materials also have the lead materials do not have a soft, longevity and so on. As a result, the material can be widely used in medical and health, the atomic energy industry, the oil industry, testing, aerospace and military anti-nuclear radiation and other areas. Moreover, with proper adjustments, the neutron shielding materials and also other harmful rays, to meet military and civilian defense needs of neutron radiation, which in the reactor, the oil exploration wells and iron and steel plants in areas such as metal flaw detection are widely Applications. At present, the preparation of new materials technology has gained 5 invention patents, it's not only the protection of industrial X-ray contact with the industry's health practitioners, but also to lead the traditional rubber production transform the plant is of great significance.

It is understood that the application of new materials, lead-free preparation of the protective clothing market in 2005, received wide acclaim users. It is expected that the new material of the protective clothing in domestic demand each year in more than 30,000.

In addition, in 2004, 2005, two years in a row Germany's international medical equipment exhibition in 2005 and the Beijing International Medical Equipment Exhibition, the product has also been widespread concern in the international market value of the delivery is expected to reach the billion.
