As an indispensable fire prevention facility in modern buildings, the working principle of fire shutter door is mainly based on the comprehensive effects of mechanical, physical and chemical aspects.
In terms of mechanics, fire shutter door realizes fire prevention function through sophisticated design and structure. It is usually composed of curtain plate, roller, motor, control box and other components. When a fire occurs, the fire shutter door will be driven by a motor to vertically lower the curtain plate from the roller, quickly block the passage or door, and form an effective fire isolation barrier.
The physical fire prevention principle is reflected in the material and structural design of fire shutter door. The main curtain surface of the fire shutter door is made of special fireproof materials. These materials will undergo chemical changes at high temperatures, absorb heat without releasing heat, and thus play a role in heat insulation. At the same time, the sealing and heat insulation of the shutter door are also carefully designed to reduce air circulation and prevent the spread of fire.
The chemical fire prevention principle is aimed at the special materials used in fire shutter doors. These materials are made of a variety of functional chemical components and can provide good heat and smoke insulation in both high and low temperature environments. Some material components can also absorb heat, further reducing the spread of the fire.
In addition, fire shutter doors also have some advanced functions in practical applications, such as automatic control and manual closing. Linked with the building fire alarm system, it can be automatically started and respond quickly to fire situations. In an emergency, people can also operate the fire shutter door through a manual switch.
The power of the fire shutter door is also one of its important performance indicators, which determines the response speed and operation effect of the fire shutter door in a fire. Generally speaking, the greater the power of the fire shutter door, the stronger its operating speed and load capacity.
In summary, the fire shutter door realizes the effective fire isolation function in a fire through the combined action of mechanical, physical and chemical principles, providing important protection for the safety of life and property of personnel.
