　　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?more importantly, baggage scanner machines Made a fighter in the product, not afraid of any competitor’s attack. https://secuzoan.com/

　　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.

　　”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.Even so, walk through metal detector We must also adhere to the quality of the industry and create unique products for the company. https://secuzoan.com/

　　How does the security inspection machine work?

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　security check

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　security check

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

　　It is not possible to generalize between memory foam pillows and latex pillows. It depends on personal pillow needs. First of all, let us understand the essential difference between them. As the name implies, their essential difference is the material. In terms of touch, latex material will be softer than memory foam. If it is a real natural latex or a latex pillow with a high content, although it is soft, its support is also very good. Secondly, in terms of the effectiveness of the pillow, the memory foam material has the characteristic of automatic temperature adaptation at 37 degrees. When the human body contacts the pillow, the pillow will automatically fit the cervical spine, perfectly fitting the physiological curvature of the cervical spine. Therefore, if you are purchasing for the purpose of cervical health care or cervical repair, then the memory foam pillow is obviously better than the latex pillow.Therefore, memory foam pillow Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://tainengjikang.com/

　　In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

　　We can choose whether to buy a memory foam pillow or a latex pillow based on our personal needs and the following situations.

　　In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

　　1. Latex is a relatively environmentally friendly material. The premise of this environmental protection is natural latex. The pillow made of real pure natural latex has excellent antibacterial and anti-mite effects, which is very suitable for infants and young children who have high requirements for anti-mite and anti-bacterial. In addition, latex feels very soft, but still has a certain degree of support, which is suitable for people who like to sleep on soft pillows.

　　2. The main function of memory foam is to absorb the pressure of the cervical spine and relieve the cervical spine. If used consistently, it can maintain the physiological curvature of the cervical spine at 12＼5. Due to its professionalism in cervical spine repair, memory foam is very suitable for people with sub-healthy cervical spine or cervical spine lesions. Using it all night can help users repair the cervical spine during sleep and effectively relieve the discomfort of the cervical spine caused by strain.

　　3. In terms of smell, newly produced memory foam has a slight smell, but this smell is harmless to the human body. Generally, the smell of memory foam pillows disappears in about 3-5 days. The real natural latex pillow has a very strong latex smell, which generally fades in 3 to 6 months, but there will always be a faint latex smell that will not disappear. Therefore, if you are very sensitive to smell, it is recommended to choose a memory foam pillow.

　　4. In terms of service life, latex material has a natural fatal weakness, that is, it ages very quickly. During use, latex material will oxidize with air, and after oxidation, it is easy to shed small dandruff on the surface and produce odor, and the pillow will become hard, which will not provide any support for the cervical spine. Although under normal circumstances, it is recommended to replace the pillow every 2 to 3 years to prevent bacterial growth, if the pillow has begun to age before it is replaced, it will not have any positive effect on the cervical spine.

　　In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

　　If it is used daily to protect the vertebrae and relieve the cervical spine, it is recommended to choose memory foam or latex material. Of course, if the focus is on the neck protection function, memory foam is definitely more preferred. The most intuitive difference between these two materials is that the real memory foam material feels harder than real latex or latex pillows with a high latex content. The real natural latex material or latex pillow with a high latex content feels quite soft, but both have very good support. Of course, this premise is that you buy high-quality products. If it is a memory foam with talcum powder added, or a latex pillow made of synthetic latex, its effect and comfort level will be greatly reduced.

　　Air source heat pump is a new type of energy equipment that uses heat energy in the air for heating and cooling. It can not only provide heating in winter, but also cool in summer, realizing the function of one machine for multiple uses. Air energy technology is becoming more and more advanced, and its product application fields are becoming more and more extensive, covering commercial hot water, heating, cooling, drying, industry and constant temperature greenhouses. Today, Mango Energy editor will take you to learn about air source heat pumps.As a representative of the industry, heat pumps for sale It is necessary to set a certain example for peers and lead the way in product quality. http://mangoenergyheatpump.com

　　1. Residential heating

　　In order to reduce coal pollution in winter, improve air quality, and ensure residents’ comfortable life in winter; in rural areas or residential areas with high ecological requirements that are not covered by heat and gas pipelines, heat pump heating is promoted.

　　2. One machine for two purposes, heating and cooling

　　Many users think that air source heat pumps can only heat, but in fact, it is a one-machine dual-purpose, and both cooling and heating can meet the requirements. The area of the evaporator of the air source heat pump product, the fins of the evaporator, and the heat exchange air volume spacing are all larger than those of the central air conditioner; in summer cooling, the evaporator becomes a condenser, and the condenser plays a heat dissipation role outdoors. Therefore. The performance of the heat energy emitted is better than that of central air conditioning; in simple terms, it can completely replace central air conditioning when cooling, and it also avoids repeated investment in the family, with one machine for two purposes.

　　3. Domestic hot water

　　The air source heat pump uses the energy in the air to generate heat energy, providing the whole family with different hot water needs with large water volume, constant temperature and high water pressure 24 hours a day; the power consumption is 1/4 of ordinary electric water heaters, 1/3 of gas water heaters and 1/2 of solar water heaters.

　　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.On the other hand, security screening machine It also brings tangible benefits to everyone and feels useful. It is a model of the industry. 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.
