Introduction To Radiation Shielding Curtains

Radiation shielding curtains are functional curtains made of metal fiber blended fabrics or metallized fabrics. They generate induced currents through metal fiber loops, creating a reverse electromagnetic field to reduce or shield electromagnetic radiation and radio wave radiation. The manufacturing process includes printed fabrics, dyed fabrics, yarn-dyed fabrics, and jacquard fabrics. Colors are available in warm, cool, and neutral tones, and by light transmittance, they are classified as transparent, semi-transparent, and opaque. The shielding effectiveness reaches up to 99.9999% (78dB). They are suitable for laboratories, command centers, residences near high-voltage lines, and living rooms, balconies, and other places requiring electromagnetic shielding, suppressing signal leakage from electronic equipment and far-infrared imaging.

Curtain materials include cotton, linen, gauze, silk, and silver fiber. Silk curtains are delicate and offer light-blocking and sound insulation, while metal fiber products have higher durability due to their anti-oxidation treatment. The conductive carbonized cotton fabric technology developed by Zhejiang Sci-Tech University uses the carbonization of waste cotton fabrics to create radiation-shielding materials, achieving a shielding effectiveness of 20-90dB while reducing production costs. In addition to electromagnetic protection, the product also features UV protection, heat insulation, and light blocking. Industry analysis indicates its application will expand into the smart home sector. Daily cleaning should avoid dehydration and direct sunlight to maintain the stability of the metal fiber structure.
