Today, Tuoxiang tablet manufacturer have summarized some issues that need to be paid attention to when purchasing tablets. Let’s take a look.from custom android tablet Looking at the development prospects, the future will always bring positive effects. https://txsongseng.com

　　1. Screen and feel

　　When purchasing a tablet, you first need to determine the purpose of purchasing the tablet. Common tablet usage scenarios can be divided into two categories: entertainment and productivity. Entertainment includes video watching, games, etc. Productivity scenarios include learning and taking notes, simple office needs, and painting needs. The purpose of the tablet can help you decide how large the screen size of the tablet to choose. Different screen sizes not only determine the screen field of view, but also determine the overall body size to a certain extent, which has a greater impact on the feel.

　　If your tablet is mainly used for playing games, you can choose a tablet with a slightly smaller screen size, which will be easier to hold and control. For example, a tablet with a screen of about 8 inches is relatively lighter, with moderate weight and size, more suitable for long-term holding, and more friendly to gamers. And tablets with a screen of about 8 inches are also easier to carry.

　　If the main purpose of your tablet is to watch videos, and there are relatively few handheld usage scenarios, you can choose a product with a larger screen size. A 10-inch or larger screen will have a relatively greater grip pressure, but the screen field of view will be significantly improved, bringing a more shocking viewing experience. In addition, if you need to use a tablet to make simple PPTs, text editing, etc., a large screen will be more efficient.

　　2. Hardware performance is very important

　　In terms of performance, if you buy a tablet mainly for playing games, tablet performance is an important focus. For a better gaming experience, it is best to choose a tablet equipped with a flagship chip. Currently, on Android tablets, products equipped with chips such as the Snapdragon 870 chip and the Kirin 9000 series can provide relatively strong performance support and meet the needs of mainstream online games. For other chips, you can check the hardware performance of the chip and the actual release effect.

　　3. Charging and battery life are indispensable

　　Tablets are usually equipped with large-capacity batteries, which bring longer battery life. Because the battery capacity of tablets is much larger than that of mobile phones, the charging speed becomes more important at this time. When we buy tablets, we also need to pay attention to the battery capacity and charging speed. If the charging power is too low, the charging time is long, which is not convenient enough.

　　4. System adaptation

　　Both Android and Apple tablets can easily meet the needs of chasing dramas and playing games. Of course, if you like playing games, you need to pay attention to the hardware performance when purchasing an Android tablet. Android and Apple tablets can also meet some simple learning and office needs, such as taking notes, simple text editing and other needs. Especially in terms of painting, Apple tablets have a better painting ecosystem, provide more professional support, and have a better experience.

　　Windows tablets are equivalent to a portable small computer, suitable for users with high productivity requirements, especially those who rely on Windows systems. This part is its unique advantage, but the experience in entertainment is relatively not so good.

　　It is worth noting that many tablets now support cross-device interconnection functions and support interaction between multiple devices. Usually, tablets and mobile phones of the same brand will be specially optimized, and the cross-device interconnection experience will be better. This part can be purchased according to the brand of your mobile phone.

　　There are many tablet products available on the market, and there will be obvious differences between different products. If you want to buy a tablet that better meets your needs, you can pay attention to the points mentioned above.

　　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.Not only does it perform well in data, non-standard fasteners price In the market share, it is also gradually expanding, so that more people can benefit. 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.

　　For many girls, it only takes two brushes to paint eye shadow, but if you want to pursue a more perfect and clean makeup, you need to use all kinds of small brushes reasonably. Of course, two brushes can’t solve it. In addition, there is the color matching of eye shadow. Some young sisters may not know much about the rules of eye shadow matching. This article is just a little knowledge about the selection, use and color matching of makeup brushes ~ Then let’s get started ~At first, professional makeup brush It developed out of control and gradually opened up a sky of its own. https://lsmakeupbrush.com

　　First, choose an eye shadow brush

　　Priming brush

　　This brush with bristles of about one centimeter in length is the largest eye shadow brush, which is mainly used to make the whole eyelid bottom. The usage is to smudge the whole eye socket with light eye shadow.

　　Color spreading brush

　　Medium and small eye shadow brushes are used to superimpose other dark colors on the background color. The skill of using them is to bring colors from bottom to top. It is recommended to prepare two medium eye shadow brushes, one with light color and the other with dark color.

　　Detail smudge brush

　　This eye shadow brush looks the same as the base brush, but it is actually the smallest size. The bristles may be only about 3mm, which is used to superimpose the heavy colors at the end of the eyes, or to draw some dark colors into eyeliner.

　　Contour brush

　　This brush is bigger than the base brush. It can be used after painting the whole eye shadow, without any powder. It just sweeps the edge of eye makeup to make the color more natural without obvious edge feeling, and it can also be used to sweep the nose shadow.

　　Eye shadow color

　　If it is not necessary for special occasions, it is best not to use too many colors in an eye makeup.

　　The background color means that the color of a large area of eye socket must be matte, not necessarily light, but it is best to be matte without flashing, which will make the whole eye feel less swollen.

　　The color superimposed on the background color is called the theme color. You can choose a brighter color, and the smudge range is less than the background color. How to say this range? You need to practice more. If you are a girl with double eyelids, you should control it around two or three millimeters. The color that is aggravated in the triangle area at the end of the eye is called the finishing touch color ~ when sweeping the end of the eye, bring a little to the lower eyelid part of the end of the eye to make the eyes deeper.

　　Finally, brighten the color, with sequins or flashing colors, embellish the eyes, eyes and lower eyelids, which can make the eyes more stereoscopic and deep ~
