Title: Application and advantages of concealed airtight hinge for fire doors.
In today's society, with the improvement of people's living standards and the enhancement of safety awareness, the requirements for the safety performance of buildings are getting higher and higher. As one of the important components of building safety, fire doors are widely used because of their functions of isolating fire sources and preventing smoke from spreading. In order to further improve the overall performance of fire doors and meet the aesthetic requirements, "hidden airtight hinge" came into being.
1. What is the concealed airtight hinge of the fire door?
1. Conceptual analysis
The so-called "concealed airtight hinge for fire doors" refers to a special device that can be installed on all kinds of fire doors and realize its opening and closing functions; At the same time, under the premise of ensuring structural strength, the product also has good sealing and concealment effect.
2. Function introduction
(1) By optimizing the design and adopting precise manufacturing technology, the joint can achieve excellent closure;
(2) The spring mechanism made of high-quality materials can make the door closing action smoother and more natural;
(3) According to different types of walls or ground environments, the corresponding fixing methods can be flexibly selected to adapt to the site construction conditions;
(4) In addition, it has many additional features, such as anti-theft and anti-corrosion.
Second, the scope of application
Because of the above advantages, most public places on the market, such as hospitals, schools, shopping malls, hotels and residential areas, will use such products for supporting installation. Specifically, it includes but is not limited to:
1. All kinds of access points, such as escape doors/fire evacuation doors set in elevator halls and corridors;
2. entrances and exits of important equipment rooms, such as key parts such as power distribution room and computer room;
3. Places where pollution sources need to be isolated in special places such as laboratories and aseptic workshops.
Third, the technical characteristics
1. Compact and light structure, convenient transportation and storage, and easy disassembly, maintenance and replacement of parts;
2. Exquisite and delicate surface treatment technology can not only keep it from rusting for a long time, but also resist the influence of bad weather and prolong its service life;
3. The sealing strip is made of environment-friendly TPV/TPE rubber products, which not only ensures the safety of long-term use, but also meets the requirements of relevant national standards and specifications;
4. The bearing part is made of self-lubricating composite material, which reduces the noise and improves the operation efficiency;
5. The supporting accessories are complete, and the user can adjust the gap size according to the actual working conditions to achieve the best use condition.
To sum up, we can see that the appearance of "concealed airtight hinge of fire door" has greatly improved the requirements of the whole construction industry for fire prevention facilities, and promoted the development of new building materials in a more efficient and energy-efficient direction. In the future, I believe that with the continuous advancement of science and technology, high-tech products like this will be more widely applied and promoted!
