The main functions of the fire-resistant and flame-retardant sealing strip: fire-resistant and flame-retardant, insect-proof, wind-proof, lightweight, anti-collision, sound-proof, smoke-proof, waterproof, and sealed. The characteristics of the fireproof sealing strip are as follows:
1. Expansion temperature: the initial expansion temperature is 199°C, and the main body expansion temperature is 347°C;
2. Linear expansion multiple: greater than or equal to 3 times the thickness of the original expansion body;
3. High temperature resistance, good combustion performance: the temperature rises to 980°C and keeps for 30 minutes, without burning or ashing;
4. Smoke-proof performance: the fire-resistant test is carried out for 60 minutes, the door is installed with sealing strips on the left and right sides, there is no obvious smoke leakage in the upper gap, and the smoke-proof performance is greater than 60 minutes;
5. Environmental resistance: under the conditions of room temperature and 90% humidity, the expansion rate remains unchanged within 5 years.
Fireproof seals and fireproof expansion seals expand rapidly when heated to close the gap between doors and windows to prevent smoke and heat from entering and ensure personal safety.
The fireproof sealing strip is mainly used for the fireproof expansion sealing strip between the door leaf and the door frame, and the fireproof sealing strip between the door leaf and the door leaf of steel door and wooden door. In the event of a fire, the fireproof and flame-retardant sealing strip will automatically expand to block the gap between the doors and prevent the air circulation between the two spaces, thus effectively preventing the early harm of the human body by thick smoke, toxic gas and hot air. and control the spread of fire. The sealing strip can be glued in the groove of the fire door gap (use self-adhesive glue), or it can be fixed in the groove of the fire door with small nails.
