A Purdue University professor of mechanical engineering and his students have created the whitest paint on record.
美國(guó)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(lái)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(kāi)發(fā)一種新的涂料時(shí)，目標(biāo)是創(chuàng)造一種能將陽(yáng)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(shuō):“大約七年前我們開(kāi)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?！?/span>
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(yáng)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(yáng)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?chē)鷾囟取?/span>
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(chǎng)上設(shè)計(jì)的拒熱涂料只能反射80%-90%的陽(yáng)光，而且不能使表面比周?chē)h(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(cè)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(shuō):“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(zhuān)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(chǎng)。
