Application and practice of material performance testing in door lock of protective door
With the rapid development of social economy, people have higher and higher requirements for the safety of living environment. Among them, door lock is one of the important tools to protect family property and personal safety, and its safety, stability and other performance indicators have attracted more and more consumers' attention. Therefore, how to test the material properties of door locks to ensure their quality and function has become a key issue of industry concern.
First, the selection of door lock material and performance test
Generally speaking, the main materials of protective door locks are stainless steel, copper, zinc alloy and some plastic materials, and different materials of door locks have different performance characteristics.
1. Stainless steel door lock: strong corrosion resistance and high compressive strength; However, it is easy to scratch and scratch, so attention should be paid to maintenance during use.
2, copper door lock: soft texture, good ductility, not easy to rust; However, due to its own characteristics, the hardness of copper door locks is low, so it is not recommended to use them in important occasions.
3, zinc alloy door lock: low density, high strength, good wear resistance and corrosion resistance, and high cost performance.
4. Plastic door lock: light in weight and rich in color, but easy to deform in extreme environment, and its service life is relatively short.
Second, the door lock performance testing method
In order to ensure the quality and use effect of the protective door lock, it is necessary to conduct a comprehensive performance test:
1. Mechanical performance test: including the determination of tensile strength, yield point, elongation after breaking, impact toughness and other indicators to evaluate the reliability of the door lock structure and its ability to withstand external pressure;
2. Durability test: By simulating the wear and tear in daily use (such as the number of switches), it is verified whether the door lock can maintain the normal working state for a long time;
3. Evaluation of anti-prying and anti-theft ability: it mainly investigates the performance of door locks in the way of resisting illegal opening (such as violent destruction), which is an essential standard to measure an excellent door lock product;
4. Fire rating: Check whether the door lock has the function of preventing the flame from spreading under the action of a specific fire source, and effectively isolate harmful substances such as smoke and toxic gas generated by combustion.
III. Conclusion
To sum up, by systematically and scientifically testing the material properties of various types of protective doors and locks, we can provide consumers with reliable reference information on product quality and help them make more informed choices when purchasing. At the same time, it is also beneficial for enterprises to continuously improve their technical level and service level and promote the healthy and sustainable development of the whole industry.
