  The principle of security inspection machine is similar to that of medical X-ray machine

  

  The principle of medical X-ray machine and security inspection X-ray machine is the same. X-ray machine has three parts. One is the tube, which emits X-ray radiation source. X-ray can pass through the material to see things that our naked eyes cannot see with ordinary light. There must be a tube or X-ray. Second, there must be a high-voltage transformer. The high-voltage transformer converts the general voltage into high voltage, and then provides the tube to generate electrons and then generate X-rays. This is the second part. The third part is the controller, which means how much X-ray I need to release. There must be a control board. All X-ray machines cannot escape this, whether it is X-ray or CT. Although its structure is very complicated, its structure should be the same.

  

  Security X-ray machines have less radiation

  

  The use of security X-ray machines is to put the luggage into the item scanning X-ray machine. After the inspection is completed, the passenger can take back his luggage and leave. The X-ray machine used for item inspection uses X-rays to pass through the object to obtain X-ray images, which are processed by computers and displayed on the computer screen to identify the image and evaluate the safety of the object. Although the principle is similar to the human body X-ray examination in the hospital, Professor Li Ziping believes that the dose of security X-ray machines should be less than the amount of X-rays irradiated to the human body. Because the security X-ray machine only needs to see the general shape of the object. Medical X-ray machines need to see the human body very clearly, so the radiation dose is greater.

  

  Therefore, there is no need to worry too much about the radiation problem of security X-ray machines. In addition, whether the radiation of security X-ray machines has an impact on the human body depends on the amount of radiation received at one time, the total amount of radiation received, the radiation time, and the human body’s regulation of these radiations. Moreover, even if the security inspection machine leaks due to quality problems, it may have an impact on the staff who work nearby for a long time, but it will not have much impact on people who pass by. It is understood that the country implements a licensing management system for the use of nuclear technology. X-ray baggage inspection equipment is a Class III radiation device, which is a low-risk radiation device.

What is a mechanical keyboard and how does it work

  As the name suggests, a mechanical keyboard is a type of keyboard that is characterized by the fact that each key is controlled by an independent micro switch. This switch is usually called an “axis”. Depending on the micro switch, mechanical keyboards can be divided into many types, such as the traditional brown axis, blue axis, white axis, black axis, red axis, as well as Romer-G and optical axis.Not only does it perform well in data, aula gaming mouse In the market share, it is also gradually expanding, so that more people can benefit. https://www.aulastar.com/

  

  What is a mechanical keyboard and how does it work?

  

  Working Principle:

  

  Physical Mechanical Switch: The working principle of mechanical keyboard is to achieve key triggering and feedback through physical mechanical switches. Each key is equipped with an independent mechanical switch, which consists of a spring and a switch.

  

  Key Trigger: When the key is pressed, the spring is compressed and the switch is switched, triggering the action of the key. This physical triggering method makes the triggering of mechanical keyboards more reliable and direct.

  

  Triggering force and triggering point: Each mechanical switch has a specific triggering force and triggering point. This means that the user needs to press a certain force to trigger the switch, and at a certain point in the key travel, the switch will complete the triggering action. This design allows users to choose different types of switches according to their preferences and needs to get the best feel and feedback.

  

  Durability: Each mechanical switch has an estimated lifespan, and usually fails after hundreds of thousands or even millions of key presses. This makes mechanical keyboards more durable than other types of keyboards and the first choice for many professional users and gamers.

  

  In addition, mechanical keyboards have higher durability and reliability than other types of keyboards, such as membrane keyboards.

How to Choose the Surface Treatment Process for Fasteners

  Choosing which surface treatment to use is a problem that every designer faces. There are many types of surface treatments to choose from, and not only should the economy and practicality of the design be considered, but also the processability of the assembly and even environmental protection requirements should be taken into consideration. The following is a brief introduction to some commonly used coatings for fasteners based on the above principles for reference.in fact non-standard fasteners price Our related products were once praised by users, which is the best self-affirmation of the products. https://jieruifasteners.com/

  

  1. Electrogalvanizing

  

  Electrogalvanizing is the most commonly used coating for commercial fasteners. It is relatively cheap and looks good. Common colors include black and military green. However, its anti-corrosion performance is average, and its anti-corrosion performance is the lowest among zinc plating (coating) layers. Generally, the neutral salt spray test of electrogalvanizing is within 72 hours. Special sealants are also used to make the neutral salt spray test reach more than 200 hours, but the price is expensive, which is 5 to 8 times that of general galvanizing. The torque-preload consistency of electrogalvanized fasteners is poor and unstable, and is generally not used for connections in important parts. In order to improve the torque-preload consistency, the method of applying lubricating substances after plating can also be used to improve and improve the torque-preload consistency.

  

  2. Phosphating

  

  A basic principle Phosphating is cheaper than galvanizing, but its corrosion resistance is worse than galvanizing. Oil should be applied after phosphating, and its corrosion resistance is greatly related to the performance of the oil applied. For example, after phosphating, applying general anti-rust oil, the neutral salt spray test is only 10 to 20 hours. Applying high-grade anti-rust oil can last for 72 to 96 hours. But its price is 2 to 3 times that of general phosphating oiling.

  

  There are two common types of non-standard fasteners phosphating, zinc phosphating and manganese phosphating. Zinc phosphating has better lubrication performance than manganese phosphating, and manganese phosphating has better corrosion resistance and wear resistance than galvanizing. Its operating temperature can reach 225 degrees to 400 degrees Fahrenheit (107 to 204 degrees Celsius). Especially for the connection of some important parts. Such as the connecting rod bolts and nuts of the engine, cylinder heads, main bearings, flywheel bolts and wheel bolts and nuts. Phosphating high-strength bolts can also avoid hydrogen embrittlement problems, so in the industrial field, bolts above grade 10.9 are generally treated with phosphating surface treatment.

  

  

  3. Oxidation blackening

  

  Blackening + oiling is a very popular coating for industrial fasteners because it is the cheapest and looks good before the oil runs out. Since blackening has almost no anti-rust ability, it will rust quickly after oiling. Even in the presence of oil, the neutral salt spray test can only reach 3 to 5 hours.

  

  4. Electroplating cadmium

  

  Cadmium coating has good corrosion resistance, especially in marine atmospheric environment, its corrosion resistance is better than other surface treatments. The waste liquid treatment cost in the process of electroplating cadmium is high, and its price is about 15~20 times that of electroplating zinc. Therefore, it is not used in general industries and is only used in some specific environments. For example, it is used for non-standard fasteners for oil drilling platforms and HNA aircraft.
