A Purdue University professor of mechanical engineering and his students have created the whitest paint on record.
美國普渡大學(xué)的一位機(jī)械工程教授和他的學(xué)生研發(fā)出了有史以來蕞白的油漆。
When Purdue University researchers set out to develop a new paint, the goal was to create one that would reflect sunlight away from a building. It turns out they also set an official Guinness world record for the whitest paint on the planet.
當(dāng)普渡大學(xué)的研究人員著手開發(fā)一種新的涂料時(shí)，目標(biāo)是創(chuàng)造一種能將陽光從建筑物反射出去的涂料。事實(shí)證明，他們還創(chuàng)造了世界上蕞白的油漆的官方吉尼斯世界紀(jì)錄。
“When we started this project about seven years ago, we had saving energy and fighting climate change in mind”, Professor Xiulin Ruan said.
阮秀林教授說:“大約七年前我們開始這個(gè)項(xiàng)目的時(shí)候，我們的想法是節(jié)能和應(yīng)對(duì)氣候變化。”
The paint reflects 98.1% of solar radiation while also emitting infrared heat.
這種涂料能反射98.1%的太陽輻射，同時(shí)也散發(fā)紅外線熱量。
Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power.
由于這種涂料從太陽吸收的熱量少于它釋放的熱量，涂上這種涂料的表面可以在不消耗能量的情況下低于周圍溫度。
Typical commercial white paint gets warmer rather than cooler. Paints on the market that are designed to reject heat reflect only 80%-90% of sunlight and can’t make surfaces cooler than their surroundings.
典型的商用白色涂料會(huì)變暖而不是變冷。市場上設(shè)計(jì)的拒熱涂料只能反射80%-90%的陽光，而且不能使表面比周圍環(huán)境更冷。
Researchers did an outdoor test with an ambient temperature of 43 degrees Fahrenheit. The paint lowered the sample temperature by an additional 18 degrees.
研究人員在43華氏度的環(huán)境溫度下進(jìn)行了戶外測試。涂料將樣品溫度降低了18度。
“That’s more powerful than the air conditioners used by most houses,” Ruan said.
阮秀林說:“這比大多數(shù)家庭使用的空調(diào)更強(qiáng)大。”
Purdue said it has already filed patent applications and researchers are working with a company to scale up the paint to put it on the market.
普渡大學(xué)表示，他們已經(jīng)提交了專利申請(qǐng)，研究人員正在與一家公司合作，擴(kuò)大這種涂料的生產(chǎn)規(guī)模，將其推向市場。
