Coating knowledge: nano coating technology to create waterproof surface

Core tip: if the surface of the object can not be immersed in water, it will show a strange effect Lotus leaf is a good example Even if it is drenched in the rain, the water drops will fall down immediately Lotus leaf is still clean and fresh In order to make the surface of an object repel liquid, scientists usually need to apply a specific chemical coating or coating on its surface The coating process is generally time-consuming, labor-consuming and easy to cause pollution Moreover, a coating is often only effective for certain liquids The surface that does not touch all kinds of liquid at all, actually only stays in the advertisement of the businessman, it is almost impossible to make it American power Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: if the surface of the object can not be immersed in water, it will show a strange effect Lotus leaf is a good example Even if it is drenched in the rain, the water drops will fall down immediately Lotus leaf is still clean and fresh In order to make the surface of an object repel liquid, scientists usually need to apply a specific chemical coating or coating on its surface The coating process is generally time-consuming, labor-consuming and easy to cause pollution Moreover, a coating is often only effective for certain liquids The surface that does not touch all kinds of liquid at all, actually only stays in the advertisement of the businessman, it is almost impossible to make it Researchers at the University of Wisconsin Madison in the United States have a new idea They use physical methods and nanotechnology to solve this problem The super waterproof surface they show is made of tiny silicon needles, which are only 400 nanometers in size This kind of surface can repel all kinds of liquids, including water, oil, solvent and detergent Look at this picture There are three kinds of drops on the super waterproof surface, water, ethylene glycol and ethanol from left to right Under the magnifying glass, we can see clearly that the three liquid balls are all piled up very high, which shows the excellent performance of super waterproof surface repelling liquid Researchers will soon be able to find applications for this super waterproof surface For example, it can be used in the wing part of a helicopter to prevent condensation and ice in high altitude and severe cold environment Since the new surface repels liquids based on physical principles, it's no surprise that it works for almost all liquids Researchers even want to use its features to make "switches." Their design is: apply electric current, suck the liquid out of the gap between the long needles, let it spread at the base of the long needles, and the liquid will be "immersed" to the surface of the object; after the power is removed, the super waterproof surface repels the liquid again 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,
