1. Ultra high shielding effectiveness
The 30mm-150mm ultra thick structure has a lead equivalent of over 30mmPb, achieving an attenuation rate of ≥ 99.9% for high-energy X-rays and gamma rays (such as Co-60 and Cs-137) ranging from 150kV to 300kV, meeting the most stringent protection requirements in nuclear medicine and industrial testing.
2. High transparency and low dispersion
Adopting optical grade high lead glass formula, with a transmittance of ≥ 80%, stable refractive index, and no radiation-induced color effect, it ensures that medical staff and operators have a clear and deformation free field of view, making it easy to observe the status of the examinee and the operation of the equipment in real time.
3. Pure material and stable performance
Lead oxide content ≥ 65%~85%, no bubbles, no oxide inclusions, no impurities, high density uniformity, ensuring no weak points in radiation shielding.
4. Mechanical strength and durability
After annealing and stress relief treatment, it has excellent thermal shock resistance; High surface hardness, scratch resistance, can withstand long-term cleaning with cleaning agents and UV disinfection, with a service life of ≥ 20 years.
5. Customized services
Support non-standard size, irregular cutting, drilling, slotting, and sandwich composite processing; Can be equipped with lead glass protective frames, lead pads, and installation brackets to achieve one-stop delivery.
Installation location: It is advisable to avoid the direct direction of the main X-ray and ensure easy observation of the subject's condition and the opening and closing of the protective door.
Framework requirement: A lead lined frame with the same level of lead equivalent must be used, with a gap of ≤ 1mm to prevent radiation leakage.
Sealing material: Only neutral sealant without acidic or alkaline substances can be used (avoid containing acetic acid or ammonia water components) to prevent chemical reactions on the glass surface that may cause discoloration.
Cleaning and maintenance: Use clean water, mild detergent, and a soft cloth to wipe; Avoid using strong acids, strong alkalis, or abrasive cleaning agents.
Environmental requirements: Avoid prolonged exposure to humid, rapidly fluctuating temperatures, or acidic air environments to prevent lead formation or surface atomization.
Attention to handling: Ultra thick lead glass weighs a lot (about 500-600 kg/m ² for 100mm thickness), and requires professional lifting to avoid single point stress causing breakage.
