　　Shielded cable is a transmission line that uses a metal mesh braided layer to wrap the signal line. The braided layer is generally red copper or tinned copper. Shielded cable is a wire with a metal braided shell specially used to reduce the impact of external electromagnetic fields on power or communication lines. This shielded cable also has the function of preventing the line from radiating electromagnetic energy outward. The shielding layer needs to be grounded, and external interference signals can be introduced into the ground by this layer.from multicore cable price Looking at the development prospects, the future will always bring positive effects. https://www.linkcablecn.com

　　The shielding layer of the shielded wire is mainly made of non-magnetic materials such as copper and aluminum, and the thickness is very thin, which is much smaller than the skin depth of the metal material at the frequency of use (the so-called skin effect refers to the distribution of current in the conductor cross section tending to the conductor surface with the increase of frequency. The higher the frequency, the smaller the skin depth, that is, the higher the frequency, the weaker the penetration ability of electromagnetic waves). The effect of the shielding layer is not mainly due to the reflection and absorption of the electric field and magnetic field by the metal body itself, but due to the grounding of the shielding layer. Different grounding forms will directly affect the shielding effect.

　　Shielding is divided into active shielding and passive shielding. The purpose of active shielding is to prevent the noise source from radiating outward, which is to shield the noise source; the purpose of passive shielding is to prevent sensitive equipment from being interfered by the noise source, which is to shield sensitive equipment. The shielding layer of the shielded cable is not allowed to be grounded at multiple points, because different grounding points are always different, and there is a potential difference between each point. If multiple points are grounded, current will be formed in the shielding layer, which will not only fail to play a shielding role, but also introduce interference. Especially in occasions where frequency converters are used frequently, the interference contains various high-order harmonic components, which have a greater impact and should be paid special attention to.

　　The shielded wiring system originated in Europe. It adds a metal shielding layer to the outside of the ordinary unshielded wiring system, and uses the reflection, absorption and skin effect of the metal shielding layer to achieve the function of preventing electromagnetic interference and electromagnetic radiation. The shielding system comprehensively utilizes the balance principle of twisted pair cables and the shielding effect of the shielding layer, so it has very good electromagnetic compatibility (EMC) characteristics. Electromagnetic compatibility (EMC) refers to the ability of electronic equipment or network systems to resist electromagnetic interference to a certain extent, and at the same time cannot generate excessive electromagnetic radiation. In other words, the device or network system is required to be able to work normally in a relatively harsh electromagnetic environment, and at the same time, it cannot radiate excessive electromagnetic waves to interfere with the normal operation of other surrounding devices and networks.

　　The shielding principle of shielded wire is different from the balanced offset principle of twisted pair. Shielded cable is to add one or two layers of aluminum foil on the outside of the four pairs of twisted pair wires, and use the reflection, absorption and skin effect of metal on electromagnetic waves to effectively prevent external electromagnetic interference from entering the cable, and also prevent the internal signal from radiating out and interfering with the work of other devices.

　　There are many steps in makeup, and the makeup tools used in different steps are different. For example, when painting eye shadow, eye shadow brush will be used, and when concealing, concealer brush will be used. So, can the eye shadow brush be used as a concealer? Concealer brush is harder than eye shadow brush, and the brush head is smaller. Concealer is generally paste, but eye shadow brush is not suitable. Let’s learn more about the difference between concealer brush and eye shadow brush.Since then, more and more people have found that makeup brush manufacturers The value of, thus affecting the choice of many people. https://lsmakeupbrush.com

　　First, can the eye shadow brush be used as a concealer brush?

　　The eye shadow brush can’t act as a concealer. The concealer brush is to dip a proper amount of cosmetics, that is, concealer liquid foundation, etc., and then smudge the edge of the concealer, remember to use it a few times. The material of eye shadow brush is not suitable for concealer.

　　Eyeshadow brushes can be roughly divided into five types according to the size of the brush head. Generally speaking, the color brushed by the big brush head is relatively light, which is suitable for a large area of eye socket, and the middle brush head is used to brush the middle color. People with deep double eyelids can get eye shadow on the wide side of the brush. Eyeshadow brush with pencil brush head is generally a necessary tool to draw a gradual feeling at the end of the eye. Small flat brush with long hair is mainly used to enhance the effect of key colors.

　　Second, the difference between concealer brush and eye shadow brush

　　1. In terms of softness and hardness, concealer brushes are generally hard, while eye shadow brushes are softer; In terms of brush head area, concealer brush head is smaller, and eye shadow brush head is bigger; In terms of usage, if you choose a concealer brush, you should adopt a point painting method, and if you choose an eye shadow brush, you should adopt a horizontal painting method.

　　2, concealer brush is mainly used to cover a small area of the face, emphasizing accuracy, so the concealer brush is hard, which is more convenient to apply. The eye shadow brush is used to apply eye shadow, which needs to be applied repeatedly on the eyelids. If the brush head is too hard, it will hurt delicate skin, so the bristles of the eye shadow brush are particularly soft.

　　3. When you need to retouch your makeup, you can dip a small amount of liquid foundation and concealer with a concealer brush and gently apply it to acne marks and other parts. In order to make the concealer and the base makeup blend together better, you can gently wipe the border with a cotton swab, so that the concealer can smudge better and blur the dividing line.

　　4. The brush head of the eye shadow brush is generally larger than the concealer brush, but there are many kinds of eye shadow brushes, and each eye shadow brush is used to apply different parts. Eyeshadow brushes with large area and flat shape are generally used as a base, which can ensure that the edges and corners are taken care of. You can dip it in white or beige, and then apply it across the entire eyelid. A small flat eye shadow brush is generally used to highlight the main color, and is usually used to smear the middle of the eyelid. Eyeshadow brushes with small area and sharp shape are generally used to repair or outline.

　　5. Concealer brush and eye shadow brush have their own strengths. If you want to create a perfect makeup, it is best to buy them together. And whether it is a concealer brush or an eye shadow brush, remember to clean it in time after use, so as to ensure that you still have a clean beauty brush next time.

　　In July 2024, a news about the upgrade of the world’s largest security company to a listed company went viral on the Chinese mobile Internet, and many Chinese netizens questioned the information of a security company to become a listed company, believing that it is difficult for a security company to become a real listed company. So, is the information circulating on the Chinese Internet platform true? Is it true that any security company in the world has upgraded to a public company? What are the requirements for a security company to become a public company?Before that, female bodyguard The market has also soared for a time, which has attracted the attention of a wide range of investors. http://huanyubodyguard.com/

　　The listing of the world’s largest security company, reported on the Chinese mobile Internet, could not be confirmed. So far, there are not many international rumors that security companies have become listed companies, and a security company needs to have many listing conditions to become a listed company. Most Chinese security companies are private, small, medium and micro enterprises, which do not have the basic conditions of listed companies. However, this type of security enterprises have indeed played a positive role in promoting the progress of social security. For example, the Huanyu Brothers bodyguard Company in Shenzhen, China, has played a good role in public security supervision in China and countries with many overseas Chinese, and has brought security protection to overseas Chinese groups around the world.

　　Whether a security company can go public and become a world-class listed company depends on comprehensive conditions. However, the existence of security service companies around the world has contributed greatly to world peace. Since all countries have security service companies, the kidnapping and terrorist attacks of rich people, politicians, stars, network celebrities, celebrities and rich people are decreasing year by year. With private bodyguards in security companies providing security protection services for world celebrities, the security crisis of world celebrities can be lifted.

　　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.To get brand praise, non-standard fasteners price It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. 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.

　　Progressive glasses can be used to see far, medium and near distances with one pair of glasses, which can solve the problem of “myopia and presbyopia”. The optical transition is smooth and there is no obvious discontinuity in the degree. However, the fitting requirements are high and the corresponding fitting parameters also require more precision. Among them, how to measure and select the progressive channel is a headache for many optical shops.For the current market situation, sustainable sunglasses It has a very advantageous development prospect and an extremely superior ecological environment. https://ymoeyewear.com/

　　Nowadays, with the high penetration of the Internet, the middle-aged and elderly people have officially entered the era of small screens, and their eye health problems have been rapidly magnified. Adult progressive lenses can greatly meet the needs of presbyopic people to see both near and far with one pair of glasses.

　　However, progressive glasses have high requirements for fitting, and how to accurately and quickly measure the key fitting parameters – channel and ADD, has troubled many colleagues in optical shops. At this year’s Shanghai exhibition, a very practical tool was discovered that can quickly and accurately measure the progressive channel.

　　What is a progressive channel?

　　Simply put, the channel is the transition length of the progressive lens from far to near. Proper channel selection is one of the key factors in whether the progressive lens is comfortable and convenient to wear.

　　Note: The channel length of progressive lenses of different brands is different, so please ask clearly when ordering! Example: The channel length of Zeiss progressive lenses is the vertical distance from the fitting cross to the starting part of the near area.

　　When the distance diopter and ADD are determined, the longer the channel length, the smoother the change from near diopter to distance diopter. However, when selecting a long channel, the downward rotation ability of the eye should be considered. Insufficient downward rotation force can easily cause unclear near vision.

　　Tools Recommendation | Rapid Calculation of Progressive Channel

　　How to accurately measure the length of the progressive channel? Measure the position of the pupil on the support piece when using it for distance and near respectively, and then measure the vertical distance between the two.
