China's hardware safety locks purchase and daily maintenance knowledge

Hardware locks are just a small part of China's vast hardware industry, but they play a crucial role in daily life, directly affecting the safety of homes, offices, and public spaces. As a critical security product, locks require strict quality standards and safety regulations—whether produced domestically or internationally. This article, brought to you by Wanshou Hardware Machine Grid, provides essential guidance on selecting and maintaining locks, helping consumers understand basic lock knowledge and improve their awareness of security practices. We hope this information proves valuable for your daily use. **How to Choose a Lock:** First, always check if the product has a clear factory name, address, trademark, and a valid inspection report from an authorized quality control agency. These details ensure the product meets necessary safety and quality standards. Second, examine the lock’s appearance. It should look clean, with a smooth surface and comfortable handling. The mechanism should operate smoothly without resistance, and there should be no unusual feeling when turning the key or locking the door. A well-made lock ensures reliable security performance. Third, pay attention to the material quality. Avoid cheaply made locks that may compromise safety. Opt for locks that feel solid and durable in your hands. Fourth, proper installation is key. Always follow the manufacturer’s instructions carefully, including the correct center distance, application scope, and opening method. Avoid installing locks on wooden doors in high-humidity areas, as moisture can cause corrosion over time. Lastly, keep the lock body clean to prevent dust or debris from entering the cylinder, which could cause jamming or even prevent the lock from opening. **Lock Maintenance Tips:** 1. Avoid exposing the lock to rain or water, as internal Springs can rust and become stiff. 2. Don’t attach too many keys to a single keyring, as the movement and weight can damage the lock mechanism over time. 3. If the key is hard to insert or remove, apply a small amount of light lubricant like WD-40. Avoid heavy oils that might attract dirt. 4. Some locks, such as those with ball bearings, shouldn't be oiled, as it can interfere with their function. 5. If the door doesn't open smoothly, try applying lubricant to the latch or the edge of the door. 6. For automatic locks (three-point, four-point, five-point), avoid making them too tight. If you have to push the door to unlock, it may lead to mechanical failure. 7. Ensure the door hinges are not too loose, as this can cause the door to sway and reduce security. 8. For anti-theft doors with a grid design, make sure the anti-theft wire is properly inserted into the latch mechanism to ensure it locks automatically. 9. Avoid pulling the key out forcefully after unlocking. Let the lock return to its original position before removing the key to prevent unnecessary wear. Maintaining your locks properly not only extends their lifespan but also ensures the safety of your home and belongings. By following these tips, you can enjoy a more secure and hassle-free experience with your locks.

Powder, Power, and Lithium - ion Battery Field 

In the field of energy power, the improvement of efficiency and the extension of life span have very demanding requirements on material performance and structural design. Silicon carbide ceramic materials outperform most metallic materials in terms of specific stiffness, thermal shock resistance, friction and wear resistance, and thermal conductivity, but they are difficult to machine and cannot be used on a large scale.
