Lead doors, as a category of doors used for protecting the safety of buildings or specific areas, come in various types and have a complex composition. Below is a detailed explanation of the types and composition of lead doors:
Types of Lead DoorsSingle Leaf Lead Door: Composed of a single door panel, suitable for smaller entryways.
Double-leaf Lead Door: Consisting of two panels, suitable for larger entrances and exits.
Sliding Lead Door: The door panel moves horizontally for easy use and operation.
Roller Shutters Lead Door: The door panel can be rolled up for easy space utilization and storage.
Fire-Resistant Lead Door: Equipped with fire-resistant properties, effectively isolates the fire source and prevents the spread of flames.
Additionally, lead doors can be categorized into electric and manual types. Electric doors can be manufactured with either top or bottom drive, depending on installation conditions and user requirements.
Composition of Lead Doors
The lead door is primarily composed of the following components:
Door panel
Material: Typically composed of lead plates, X-ray transparent glass, and iron plates.
Structure: Generally divided into an inner and outer layer, filled with insulating materials such as air or foam plastic. The inner surface is typically made of sanitized materials, easy to clean and disinfect.
Door frame
Material: Typically made of iron or steel plates welded together.
Function: Serves as the skeletal support for the door leaf, allowing for the filling of insulating material inside to prevent radiation from penetrating through the side of the door frame.
Hinges: Used to connect the door leaf and door frame, allowing the door leaf to rotate around the hinge axis for opening and closing.
Door bolts, clamping mechanisms, and buffer blocks: These components ensure the tight and stable closure of the door leaf.
Actuator (for electric doors): Can be equipped with electric or hydraulic rods as actuators to enable automatic door opening and closing.
Safety Device (for Electric Radiation Shielding Lead Doors): Equipped with door machine interlock, operational indicator lights, and radioactive ionization signs, ensuring safe use.
Sealing Device: Typically made of rubber or silicone rubber, used to prevent radiation leakage and ensure the door's radiation shielding effectiveness.
Summary
Lead doors, as a specialized category, not only come in various types to cater to different scenarios but also boast a complex structure that guarantees their excellent protective performance and durability. When selecting and using lead doors, it's crucial to choose the appropriate type based on actual needs and pay attention to relevant details to ensure they operate at their best.
Differences and Advantages Between Industrial Lead Doors and Medical Lead Doors
Difference
Structure and Materials: Industrial lead doors and medical lead doors differ in structure and materials. Medical lead doors typically adhere to higher protection standards, with thicker lead plates filled within the door frame and door leaf to provide enhanced radiation protection. Industrial lead doors may place more emphasis on practicality and durability, with thinner lead plates.
Function and Application: Industrial lead doors are primarily used for radiation protection, such as in industrial X-ray inspection rooms. Medical lead doors are used in hospital settings, especially in areas requiring high radiation protection like radiology departments and CT suites.
Advantages of Medical Lead Doors
The advantages of medical lead doors lie in their robust radiation protection capabilities, effectively blocking X-rays and other radiations to safeguard the safety of medical staff and patients. Additionally, medical lead doors typically offer excellent sealing and durability, ensuring long-term stable operation in high-traffic hospital environments.
Advantages of Industrial Lead Doors
The advantages of industrial lead doors lie in their strength and practicality. They are typically capable of withstanding significant impacts and pressures, making them suitable for industrial environments. Moreover, the design of industrial lead doors usually emphasizes functionality, accommodating various door opening sizes and radiation machine power requirements.
