1. Introduction of the Door Bottom Seal
Automatic door seal:
Installed in the door inside the fire door, the door is closed, automatically down the activities of the seal to suppress the ground, closed the door and the ground of the gap; the door open when the active seal will automatically put away from the ground, and the ground without any friction The
Daily to prevent external dust, smell, mosquitoes, hot and cold air, noise, light and other places from the bottom of the gap into the room to protect the indoor environment.
At the beginning of the fire, to prevent toxic flue gas from the door gap into the room. With the development of fire, the temperature increases, it is equipped with fire expansion material by the temperature of the excitation, expansion quickly and completely closed the door gap, to prevent "channeling fire."
It must be self-extinguishing, flame retardant, flame retardant material manufacturing, and installation does not reduce the safety level of the fire door, it is important to pass the official certification.
2. The principle and installation of the automatic sealing strip
When the door closed, through the transmission mechanism to the stalls to the ground or the threshold, so as to achieve the purpose of sealing sound insulation.
1) Installation of the Door Bottom Seal
Door Bottom Sealing strip is divided into two kinds of unilateral or double pressing key. Unilateral compression button according to the design requirements can be installed in the door lock or hinge side, bilateral compression button at the same time pressure, the dust can be automatically extended, that is, a compression button installed on the side of the lock, another compression key installation On the door side of the door. In particular, it is important to note that there is no postponement of the double-compression key-type door seal at the time of extension and withdrawal, thereby increasing the service life of the seal.
2) the door of the automatic seal of the application
* The door of the application of the occasion to determine the door seal the wind of the material.
* PVC door seal for high temperature, noise occasions.
* High temperature flame retardant silicone door seal for DIN 4102 standard fire doors and DIN 18095 standard smoke doors.
* Door Bottom Seal with the threshold in combination, you can greatly improve the effect of the seal.
* If the bottom of the carpet or different materials for the floor of the joints, it is recommended that the best use of the door at the same time automatic sealing and the threshold.
