巴西圣保罗大学化学院的研究人员经过两年的研究,破解了蜻蜓损坏汽车漆面之谜。 研究人员发现,由于汽车漆面在日照之下强烈反光,蜻蜓误把漆面当成水面,就会在上面产卵。蜻蜓卵会在车体表面温度超过70℃时产生一种类似硫酸的酸性物质。大约3小时后,这种酸性物质便产生作用,严重腐蚀汽车漆面。在强烈的日照下,绿色、红色和深蓝色汽车的表面温度可达到85℃,黑色汽车的表面温度可达到92℃,而白色和银灰色的汽车漆面则较
After two years of research, researchers at the University of Sao Paulo’s College of Chemistry cracked the mystery that dragonflies damaged the car’s paint. The researchers found that because the paint on the car reflects strongly under the sun, the dragonfly spawn the paint mistakenly and spawn on it. Dragonfly eggs produce a sulfuric acid-like acid when the body surface temperature exceeds 70 ° C. About 3 hours later, this acidic material has a role, serious corrosion car paint. Under intense sunshine, the surface temperature of green, red and dark blue cars can reach 85 ℃, the surface temperature of black cars can reach 92 ℃, while the white and silver-gray car paint is more
