How to choose a mobile phone screen protector

Now mobile phone screens use special tempered glass. The toughness, hardness, and scratch resistance of the strengthened glass have been significantly improved. The Mohs hardness is also greater than 6.5, so the hardness is much lower than 6.5 nails, knives, The key cannot scratch the screen.


So what can scratch the screen? The answer is sand. The hardness of sand is 7, slightly higher than that of glass, and it is very common. When you accidentally put one or two grains of sand in your pocket or bag, it may leave one or two scratches on your phone. But this is an accident after all, and the screen of a mobile phone is not easily scratched under normal circumstances.


Therefore, the film is like buying insurance for the mobile phone screen. What is prevented is that one in ten thousand possibility, so that you no longer have the nervousness of "don't hurt" when the phone is running naked. As for insurance, it depends on personal usage habits!


The main purpose of the screen protector is to prevent scratches. The most intuitive indicator for evaluating whether it can cause scratches is the Mohs hardness. In theory, only objects with higher Mohs hardness than the mobile phone screen can cause scratches on the screen.


There are too many films on the market, and the price of a single sheet ranges from a few hairs to a few hundred yuan. But in terms of material, there are only two types of mobile phone films: plastic film and glass film. Plastic films include high-definition film, matte film, diamond film, mirror film, etc., to name a few. Glass film is what we often call tempered film. What are the advantages and disadvantages of these mobile phone films?


High-definition film: High-definition film is a relatively common mobile phone film in certain treasures and roadsides. Generally, the price of one film is not more than 1 yuan. The advantage is that it has little effect on the screen display and is still very clear. The disadvantage is that after pasting, the phone becomes a fingerprint collector, and within a few clicks, the screen becomes a world map.


Matte film: In order to deal with fingerprints, many people will choose matte film, but this kind of film has such an advantage. After attaching the matte film, the resolution of the screen dropped sharply, and the fineness of the screen instantly returned to before liberation, which is simply an insult to the screen! This experience is even far inferior to a high-definition film covered with fingerprints!

How to Hang a Suspended Ceiling From Steel Beams

The suspended ceiling hangs under the roof or floor structure above, hiding ugly mechanical and electrical equipment from the view, while also allowing you to easily reach these equipment as needed.While wooden frames usually support such ceilings, in rooms where metal frames are used instead of traditional wood, you can also hang ceilings from steel beams.Hanging the ceiling from the beam requires you to use a special clip to connect the support line to the beam without compromising its structural integrity.Measure 4 inch down from the bottom of the lowest beam, pipe or pipe in the ceiling space.If you plan to use panel fluorescent lamps in your ceiling, add an additional 2 inch to this measurement.Make a mark on the wall indicating the location of the facade.Set up a laser level to extend the mark you made on the wall to the entire wall length.Draw a chalk line on the wall to mark the position.Mark all four walls repeatedly with chalk lines indicating the height of the ceiling.Instal

Level Measurement Solutions

Makeup water treatment is an important component of steam generation. It is the means to resupply the system with water suitable for boiler and other operations that, was lost in the cycle.The steam generation cycle, level control for the water treatment process is not necessarily about efficiency, but rather, accuracy, reliability and safety, while providing proper inventory management to ensure chemical and makeup water supply meets demand. The focus is on the chemical component of the makeup water treatment since it presents difficulties for level technologies that may work perfectly on non-chemical applications related to the water treatment process or those with limited variations in the contents of the vessel's vapor space. Although important measurements such as ammonia, acid, caustic and other chemical storage tanks are not difficult level applications by any stretch, small nuances in how the vessels are monitored relative to level technology can have a dramatic effect on t
