Scientists Created the Whitest Paint Ever
科学家创造了有史以来最白的油漆
Researchers at Purdue University have developed an “ultra-white” paint that reflects 98 per cent of sunlight and deflects infrared heat, allowing buildings to cool below the surrounding air temperature.
普渡大学(Purdue University)的研究人员开发出了一种“超白”涂料，它能反射98%的阳光，并转移红外热，使建筑物的温度降至周围空气温度以下。
The paint, which the university describes as the “whitest paint on record”, owes its cooling power to barium sulphate – a pigment derived from the mineral barite – and reflects up to 98.1% of sunlight.
该大学将这种涂料称为“有史以来最白的涂料”，它的冷却能力归功于硫酸钡(一种从重晶石矿物中提取的颜料)，可以反射98.1%的阳光。
