Coating classification: Super waterproof material

Core tip: US scientists have recently developed a new waterproof material by using laser etching technology, so that water drops falling on the surface can be directly bounced away The study was led by Chunle Guo, an optical physicist from the University of Rochester in New York They use laser to etch micro patterns on the metal surface at the micron and nanometer level, which makes the material surface have very strong water repellency or drainage characteristics When water drops on such a surface, it is repelled and bounces away directly The research was published in the January 20 issue of the Journal of Applied Physics Super waterproof material: Yes Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint House News: US scientists have recently developed a new type of waterproof material by using laser etching technology, so that water drops falling on the surface can be directly bounced away The study was led by Chunle Guo, an optical physicist from the University of Rochester in New York They use laser to etch micro patterns on the metal surface at the micron and nanometer level, which makes the material surface have very strong water repellency or drainage characteristics When water drops on such a surface, it is repelled and bounces away directly The research was published in the January 20 issue of the Journal of Applied Physics Super waterproof material: it can make the surface water drop bounce away directly Compared with the typical chemical coating or coating, the surface of such material is more waterproof and not easy to wear The flat bottomed non stick pot we use in our life is coated with polytetrafluoroethylene The surface coated with polytetrafluoroethylene needs to be tilted to 70 degrees to let the water flow away, while the new material needs to be tilted to no more than 5 degrees In addition, this special surface also has a strong self-cleaning characteristics When the water drops are bounced away from its surface, the dust falling on the surface will also be taken away To test its self-cleaning function, researchers used a vacuum cleaner to spray dust on the surface of the material It is found that only 3 drops of water can remove half of the dust particles on the surface of the material, and 12 drops can remove all the dust successfully, while the surface of the material is completely dry and spotless In developing the surface of the new material, the team used powerful but short laser pulses to etch the surface of platinum, titanium or brass Although each laser pulse lasts only about one millionth of a second, the peak power reached is equivalent to the total power of the whole North American power grid The application prospect and imagination space of this kind of waterproof material is very broad: it can be used on the surface of the aircraft wings to prevent the danger of water droplets freezing when the aircraft is flying, it can be used on the surface of the car so that the car owners can no longer wash the car, and it can even be used to develop the toilet without cleaning, which can send benefits to the water shortage areas in Africa In addition, the researchers also use the same laser etching pattern technology to blacken the metal, so that the surface of the material also has a good light absorption characteristics When it is applied to the solar panel, it is waterproof and does not need to be cleaned Of course, there are still many challenges facing this technology, such as using laser to etch an inch (2.5cm) long and wide area on a metal surface in an hour In the future, the team will try to apply this method to non-metallic materials If it can be realized, the roof, tent, clothes and so on will be completely waterproof and self-cleaning Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
