1. Ordinary radiation-proof glass generally uses nickel alloy wire mesh technology, shielding effect is good, but the light transmittance is low, the visual impact, can distinguish the color white, red, orange, yellow, green, blue, purple, Reflectivity generally less than 8%, after special surface treatment, strong impact resistance, surface stress greater than 400MPa level.
2. High lead optical glass. Mainly in the glass composition by adding a higher atomic number of oxides, including mainly PbO, in addition to BaO, La2O3, Bi2O3, WO3 and so on. Such glass has good radiation protection performance, but the chemical stability is poor, the poor resistance of the glass itself is easy to change color and other issues.
3. Radiation-proof plexiglass .20s fifties and sixties of the 20th century, the world began to study the radiation-proof plexiglass, most of these glass with methyl methacrylate (MMA) glass, and in which the introduction of lead, barium, Sm and other metal elements to achieve its radiation protection performance. The main drawback is the low strength plexiglass strength, scratch resistance is poor, the scope of the ray shielding is still relatively limited and so on.
