The reason why the QR code access control system is widely used nowadays, in the various large and small areas and high-end office buildings and schools, etc., the two-dimensional code access control system will be used to replace the traditional access control system. The main reason is that it has more professional and safe use effect. It will also improve the efficiency of office management, the pressure on security work management will be greatly reduced, and natural applications will be fully promoted.
1, safe, efficient and convenient
By using the two-dimensional code access control system, it is easier and more convenient to go out at home, especially if you don't have to worry about forgetting to bring the key or the access card, because you can directly scan the code directly through the QR code on the mobile phone, safely and efficiently. Convenient, the staff will be more worry-free in management, through the big data information processing, better understand the usual access data, and effectively carry out safety work summary.
2, easy to carry out security management
Many office buildings have security doors between the floors. This security door allows only some people to enter and exit. Traditional access cards can only be accessed by entering a password. This makes it difficult to conduct comprehensive security management. By using the QR code access control system, Naturally, it can achieve a more secure and intelligent management effect, avoiding some casual access and making safe work management smarter.
3. Reduce visitor management costs
Different communities also have office buildings and other environments, and usually do not have the function of visitors. However, after using the QR code, the visitor management work can be made easier, because the owner directly determines whether the visitor is Allowing access, property staff or security personnel, without the need for confirmation, can reduce visitor management costs and improve daily work efficiency.
In summary, the reason why the two-dimensional code access control system is widely used is because it has a good use advantage, meets the specific requirements of security in various environments, and improves the efficiency of property management, major office buildings and scenic spots. The efficiency of work management is promoted. In short, the wide range of applications in different environments can have better advantages.
Metal Alloy Powder
Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
