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.By comparison, it can be seen that non standard fasteners It has certain advantages and great cost performance. 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.

Comparison between security X-ray machines and medical X-ray machines

  X-ray machines are mainly divided into medical X-ray machines, that is, medical X-ray machines, and the other type is the luggage X-ray machines that are most commonly used in stations, airports, customs and docks, so some people also call them X-ray luggage security inspection machines or security inspection X-ray machines. However, some people also have doubts: What is the difference between the two? Does security inspection X-ray machines have radiation hazards?Actually, it’s not just this reason, security screening machine Its own advantages are also obvious, and it is normal for the market to perform well. https://secuzoan.com/

  

  security x-ray machines

  

  ZA100100D

  

  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.

How do security X-ray machines distinguish between explosives, drugs, guns, knives and other dangerou

  As the economy develops more and more, people’s living standards improve and their requirements for security are getting higher and higher. At the same time, due to factors such as wars in the third world, terrorists and extremists, domestic airports, railway stations and mass gathering places are equipped with more and more high-end security equipment.Since then, more and more people have found that baggage scanner machines The value of, thus affecting the choice of many people. https://secuzoan.com/

  

  The performance of security inspection equipment has improved a lot compared with previous years. Security inspection X-ray machines are essential equipment for security inspection channels. How this equipment can distinguish dangerous items such as explosives, drugs, guns, knives, etc., we need to start with the principle of security inspection machines.

  

  x-ray machines

  

  ZA5030A

  

  The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

  

  The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

  

  ”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

  

  So how does the security inspection machine detect these dangerous items?

  

  1. Image monitoring method

  

  Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

  

  2. Color analysis method

  

  The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

  

  Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

  

  Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

  

  Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

  

  Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.
