Importance and technical development of special high-temperature resistant and heat-insulating hinge for fire doors
With the development of society and the progress of science and technology, people have higher requirements for the safety performance of buildings. As an important part of building safety, fire doors have been gradually valued by people. Among many fire door fittings, high-temperature resistant and heat-insulating hinge is an important connecting part, and its quality and function are directly related to the overall performance of fire doors.
1. What is a heat-resistant and heat-insulating hinge?
High-temperature-resistant and heat-insulating hinge is one of the key components installed on fire doors, which is mainly made of steel and has good heat resistance and corrosion resistance. It is mainly used to connect the door leaf with the door frame so that it can be opened and closed flexibly. In case of fire, it can withstand high temperature and maintain stable mechanical properties, ensure the normal work of fire doors and win valuable time for personnel evacuation.
Second, the importance of high-temperature resistant and heat-insulating hinges
1. Ensure safety: the high-temperature resistant and heat-insulating hinge can withstand the flame attack of more than 800°C for more than 2 hours, and still maintain good stability in case of fire, so as to ensure that the fire door can effectively block the spread of fire for a long time and protect the safety of life and property.
2. Improve the use experience: the high-quality high-temperature resistant and heat-insulating hinge is made by advanced production technology, which not only has a smooth and delicate surface, but also runs smoothly without noise, thus improving the use experience of the whole product.
Third, the technical characteristics of high-temperature resistant and heat-insulating hinges
In order to meet the needs of different occasions and enhance the competitiveness of products, modern high-temperature resistant and heat-insulating hinges usually have the following outstanding advantages:
1. Material science: Special alloy material is selected as the main structural part, which has extremely strong compressive strength and excellent oxidation resistance;
2. Reasonable structural design: optimize the internal structural layout to make all parts closely combined and easy to disassemble and maintain;
3. Exquisite surface treatment technology: the metal surface is treated by electroplating or painting to prevent rust and corrosion, thus prolonging the service life and beautifying the appearance.
IV. Prospect of future trends
With the country's increasingly strict requirements for public facilities construction and fire safety standards in residential areas, the market will be more inclined to choose products with good performance and in line with relevant certification standards. Therefore, we can foresee the following development trends in the next few years:
1. Application and promotion of new materials: new lightweight and high-strength materials such as carbon fiber composites will be more widely used in this field;
2. Improvement of automatic production: from raw material processing to final assembly, automatic operation mode will be gradually realized to reduce labor costs and improve efficiency;
3. Multifunctional integration enhancement: A comprehensive solution integrating waterproof, sealing, burglar alarm and other functions will become the mainstream development direction;
In short, with the improvement of laws and regulations in China's fire protection industry and the promotion of scientific and technological progress, the future high-temperature resistant and heat-insulating hinges will surely move towards higher-end intelligence!
