Classification Of Radiation-proof Glass

- Apr 02, 2018 -

1. The general radiation protection glass generally adopts the nickel alloy mesh technology, the shielding effect is good, but the light transmittance is low, has the influence to the vision, can distinguish the color to be white, red, orange, yellow, green, blue, blue, purple and so on, Reflectivity is generally less than 8%, after special surface strengthening treatment, strong impact resistance, surface stress greater than 400MPa.


2. High-lead optical glass. The main component is the addition of oxides with higher atomic number in the glass composition, mainly PbO, BaO, La2O3, Bi2O3, and WO3. Such glass has a good radiation protection performance, but has a poor chemical stability, and the glass itself has poor resistance to radiation and is susceptible to discoloration.


3. Radiation-proof plexiglass. In the 1950s and 1960s, research began on radiation-protected plexiglass worldwide. Most of these glasses were made of methyl methacrylate (MMA) glass, and metal elements such as lead, antimony, and bismuth were introduced into the glass to achieve its prevention. Radiation performance. The main disadvantages are the low hardness of plexiglass, poor scratch resistance, and limited radiation shielding.
