Actually come to the manufacturer of raincoats. The Police Department has stipulated that the reflective strips of police uniforms must meet the reflective coefficient of 500 degrees or more. It can be seen from 500 meters away. The reflective raincoats that the general public buys outside have a coefficient of only 200 to At 300 degrees, the visibility is only 100 meters, and the degree of reflection is much worse. At present, cheap reflective windbreakers and raincoats can only reach this level. Therefore, it is recommended to buy raincoats or windbreakers with brighter colors such as yellow and fluorescent. Raincoats of various colors each have different functions, emphasizing waterproof and windproof, and also stressing comfort. However, for safety, people now choose reflective designs more emphasis on them. People: "It's brighter! Because if you encounter danger in the mountains, it's safer and more noticeable." Blowing the whistle and holding the baton, standing at the intersection at night when the vehicle is stopped for inspection, the police can only Reflective vests are used to ensure safety, but what is the difference with the raincoats bought by the general public? Reporter Luo Yixin: "For example, what is the difference between these two new and old police raincoats? Let's actually test it with reflection coefficient lights." What is the difference between the two new and old police vests? Let's use the reflection coefficient actual test to see. Look. According to the industry, the reflectance coefficient of the reflective strips is the same. The main reason is that the old model is dark blue in appearance. The new model is equipped with fluorescent yellow color. The material of the old model is nylon and PVC, and the new model is nylon and PU, which is more breathable. Comfortable. The raincoats bought by the general public are much worse than those used by the police. The police use regulations to reach 500 to 600 degrees, which is quite bright and slightly less reflective than the mirror; the general raincoat has a reflection coefficient of 200 to 300 degrees, which is very dark under the light, 100 It is almost invisible beyond meters, and the material is also. General raincoats are usually not breathable and thick for waterproofing. The industry also said that in fact, the Police Department has regulations, not only for comfort, but for safety, there are certain standards for the reflectance of the reflective strips. Raincoats: "The raincoats used in the police system must have a reflection coefficient of 5 or 600 degrees. Generally, the raincoats on the market only require 200 to 300 degrees." Red and blue flashes and flashes to improve the warning effect, except for reflections. The LED light armbands should also be added to the strip to improve visibility and ensure that law enforcement officers can be more at ease on duty.
