Lead doors are categorized into two main types: radiation-proof single-leaf lead doors and sliding radiation-proof lead doors. Both types can be equipped with electric systems, with more radiation-proof sliding lead doors commonly fitted with electric systems. How should these two types of radiation-proof lead doors be maintained and cared for? What are the differences between them?

Commonalities in Maintenance of Radiation Shielding Lead Doors:

1. Commonly available lead door exteriors feature either stainless steel decorative panels or painted panels. During use, it is essential to regularly wipe away dust from the radiation shielding lead doors to maintain their clean and glossy appearance. The stainless steel panels should be cleaned with kerosene or sewing machine oil once a month. Even stainless steel can be corroded by dust and dirt; over time, this can lead to pitting on the surface, affecting the aesthetic appeal of the radiation shielding lead doors. For painted panel lead doors, simply regular dust removal is required.

2. Radiation shielding lead doors with lead glass observation windows require daily cleaning of the observation window. Use a soft cotton rag for cleaning and avoid sharp objects to prevent surface scratches, which can affect aesthetics and the radiation shielding effectiveness.

II. Distinctive Aspects of Radiation Shielding Lead Door Maintenance and Care:

Single-leaf lead doors are opened via a pivot axis or hinge. Lead doors with a pivot axis should have lubricating oil injected into the bottom corner bearing every two weeks; it is strictly prohibited to use engine oil instead. The upper pivot should be lubricated monthly. Regularly observe the pivot angle position to prevent foreign objects from damaging the lead door pivot during the opening or closing process.

2. Regularly inspect the contact surfaces of the lifting wheel and slide track on radiation shielding sliding doors, ensuring they remain clean. Since part of the sliding door is suspended, it's also crucial to frequently check the tightness of the lifting wheel screws. Loose screws could lead to safety accidents, which would be a disadvantageous trade-off.

3. Whether for single-opening or sliding lead doors, many mid-to-high-end customers opt to install an electric system to reduce the labor intensity for both medical staff and patients when opening the doors. Lead protective doors with an electric system require not only regular cleaning and maintenance of the door surface but also a routine check and adjustment of the electric system every two weeks. This includes verifying proper operation, checking for increased running noise, inspecting for any loose or elongated drive belts or chains, ensuring the access control system is functioning correctly, checking for any faults in the door light interlock system, and verifying the operation of safety devices such as work indicator lights and ionizing radiation signage.
