How do fire resistant rolling shutter doors achieve fire resistance?

Nowadays, many large places usually use fireproof rolling shutter doors, why? In fact, in many public places, people usually leave behind doors to allow people to enter and exit, but fireproof rolling shutters are a good choice for taking fire prevention measures. Fireproof rolling shutter is an indispensable fire prevention measure in modern architecture, which can prevent the spread of fire and prevent the spread of fire. The function of fireproof rolling shutters is to prevent fires, prevent their spread and spread. In fact, the fire prevention method of fire resistant rolling shutters is horizontal fire prevention, where flames are isolated in a certain space. Fire resistant rolling shutters are composed of various structures such as curtain panels, seat plates, bases, rollers, boxes, etc. Therefore, installing fire resistant rolling shutters is the general term for fire resistant rolling shutters at firewall partitions. There are many types of fire resistant rolling shutter doors that can be classified by material, including steel fire resistant rolling shutter, composite fire resistant rolling shutter, and inorganic fire resistant rolling shutter. According to installation methods, there are two types of fire resistant rolling shutter doors: inner wall and side wall. When classifying in the opening direction, there are upward rolling fire resistant rolling shutter doors and side rolling doors. Users can choose fire resistant rolling shutter doors according to their actual situation.

At present, the size, width, and height provided by domestic fire-resistant roller shutter manufacturers can reach 15 meters. It can be hidden on the ceiling and matched with temperature sensors, smoke sensors, and high-temperature fuses. Every time the smoke signal arrives, the fire shutter drops to a height of 1.8 meters above the ground, forming a smoke barrier to prevent smoke from spreading to other areas. When the temperature signal arrives, the fire shutter drops to the ground, the fire is cut off, sound and light are emitted, and an alarm is issued to indicate rapid evacuation. If someone has not evacuated to the affected area, the fire shutter can be pulled 1.8 meters above the ground through the buttons on both sides of the door, and closed after the person has escaped, to prevent smoke from leaking to the back of the shelter.

1. Special materials. There are four layers inside the fireproof rolling shutter door. The first layer is decorative fabric, the second layer is fire-resistant fabric, the third layer is fire-resistant fabric, and the fourth layer is radiation resistant fabric. However, general fire doors are only made of metal materials and cannot have fire protection function

2. Non combustible. The material inside the fireproof rolling shutter door is difficult to burn even in a gas stove, indicating its fire resistance.

3. Sensitive sensing. When the fire shutter door detector detects flames and smoke, if the temperature detector receives a signal, it will first lower the fire shutter door by half. When receiving the second signal, all the fireproof rolling shutter doors are lowered. This can achieve good fire and smoke prevention effects.
