Ten years ago, we smashed the big butt CRT and ushered in the era of LCD monitors; five years ago, LCD monitors bid farewell to CCFL backlights, ushered in a safer and more environmentally friendly LED era. In 2014, coincided with the five-year development of the display, AOC's anti-BlueLight technology, which has an exclusive patent for a technological revolution with eye health, has emerged. This technological revolution means that we are no longer poisoned by Blu-ray, in exchange for the era of clear blue light in the display device that AOC is about to open. ◠Blu-ray, irreversible health damage! The short-wave blue light of 410-450nm is very harmful to the eyes. The blue light with the greatest harm to humans is the short-wave blue light with a wavelength of 410-450nm. Short-wave blue light will illuminate the eyes for a long time, which will generate a photoreactive substance free radical in the eye, which will lead to Retinal pigment epithelial cell decline. After the photoreceptor cells lack nutrients for a long time and gradually decline, it will eventually cause an irreversible eye disease macular degeneration. This disease affects central vision and causes blind spots in the eyes. According to statistics from the medical community, the number of people with macular degeneration has increased significantly in recent years. Since there is no medical method to cure this disease, medical experts have called for conscious prevention of blue light hazards in life. ◠Blu-ray, it is impossible to prevent! In recent years, blue light and PM2.5 and radiation have been collectively referred to as the three invisible hazards in life. The reason why it is called invisible harm is that the average person is not conscious of the defense because there is no short-term illness. However, even if it is consciously prepared, with the wide application of LED backlight technology, it is hard to prevent for the average person. How many LED display devices do you have to touch each day? Blue light is the same as PM2.5 and radiation, and is a derivative of economic and technological development to a certain extent. To be exact, it is a necessity for LED-backlit displays at this stage. The TVs, monitors, mobile phones, tablets and other electronic devices we are looking at now use the first generation of traditional LED backlight technology, which is illuminated by blue light with warm phosphor powder. Because it is ubiquitous in the screens we touch every day, especially in today's LED backlight screens such as mobile phones, tablets, monitors, TVs, etc., we have almost nowhere to escape. In view of the coverage and harmfulness of Blu-ray, we must not be underestimated. ◠AOC's second-generation LED backlight technology is the most perfect net blue solution. In the face of Blu-ray, the health killer, AOC took the lead in technological innovation through LED backlighting of LED phosphor powder, thus solving the blue light hazard of LED at the root. As shown in the test results, the 410-450nm short-wave blue light emitted by the first generation of traditional LED backlights is the main cause of macular disease, while the second-generation LED-backlit liquid crystal display improved by AOC changes the peak spectrum of blue light intensity. The distribution (peak wavelength from 444 to 460 nm) removes more than 90 short-wave blue light that damages the eye, which solves this problem from a hardware perspective, significantly reducing the damage that Blu-ray can cause to the user. By changing the peak spectral distribution of blue light intensity, removing more than 90 short-wave blue light that damages the eye compared to the common anti-blue glasses on the market, such as anti-blue glasses, anti-blue film, and display software to reduce the blue light intensity, AOC starts from the root of the problem. The technological innovation of LED backlight raw materials has realized the true hardware net blue. Compared with the existing anti-Blu-ray method, AOC's second-generation LED backlight hardware net blue technology has three significant advantages: First, the effect of net blue light is more significant. Compared to the 30-70 anti-Blu-ray technology, AOC's hardware net blue technology can filter out diseased blue light up to 90 or more; secondly, it is cheaper. Compared with the anti-Blu-ray glasses that cost thousands of dollars, the hardware blue technology can achieve less than 1/10 of the cost, and can be used in various LED backlight devices. The easy-to-popular features help to further reduce costs. Third, image quality loss Almost zero. Compared with some current display devices, the brightness and color accuracy are reduced by the OSD menu to achieve anti-blue light. AOC achieves a clear blue without losing color accuracy and brightness, so that users can enjoy the health hazard while enjoying Display the color performance of the device to 臻. Comparison of several anti-blue methods on the market If the first-generation LED backlight replaces the CCFL with the concept of mercury-free and low-energy environmental protection, then the AOC's net blue-light technology focuses on the revolutionary upgrade of the concept of health and promotes The development of LED-backlit displays has created a new concept for the second generation of LED liquid crystal displays. In view of the lower cost of AOC's exclusive patented technology and the more complete problem solving, this technology is expected to be adopted in various fields such as mobile phones, tablets, displays, and televisions in the future. By then, we will not talk about blue changes.
The composite pipe has fully exerted the high strength, toughness, impact resistance, good welding performance and high hardness, high wear resistance, corrosion resistance and heat resistance of the steel tube, which overcomes the low hardness, poor wear resistance and poor toughness of the steel tube. specialty. Ceramic tubes are widely used in the following industries:
First, the mine:
1. Coal water slurry, coal washing mud, mine filling and coal powder in coal industry;
2. Metal mines: pipeline transportation of concentrates and tailings.
Second, metallurgy:
1. Pipes for coal injection and slag transfer in blast furnaces of iron and steel plants;
2. Pipes for transportation of iron alloys, refining, and optimization of steelmaking.
3. Cement Plant: Raw slurry transportation, pulverized coal transportation, hoist cutting, concrete conveying pipeline of rotary kiln wet production line.
Fourth, coal-fired power plants in addition to ash, slag, powder feeding, powder return, desulfurization of lime gypsum slurry transport.
