Wujiang Private enterprise has developed a radiation cooling fabric, which will be made into a car cover, covering the car exposed to the sun for a long time, so that the temperature inside the car can drop more than 15 degrees Celsius. Yesterday, the reporter from Jiangsu together super new material science and technology Co., Ltd. to understand that this as early as 3 years ago began to develop products, after thousands of tests, technology has been mature, large-scale mass production.

In hot summer, the temperature inside a car placed outdoors for a long time can reach 55℃ or more under the sunshine. What makes this "coolable" fabric different is the new material attached to the ordinary fabric, which is only 30 microns thick. Don't look at this layer of ultra-thin finishing, the temperature difference between shade and sunshine under the hot sun is 15℃ to 30℃, shade is cool, and the coating thickness is greater, the temperature outside the temperature is higher, the effect is more obvious.

Yesterday, in Jiangsu ultra new material science and technology co., Ltd. on the outdoor lawn, the reporter did a test experiment. At that time, the outdoor temperature was 39.7 degrees Celsius. The reporter began the experiment by placing two identical cold drinks on two steel plates, one of which was attached to a film containing the new material and the other to a normal film. After a few minutes, the cold drink on the steel plate coated with the new material melted significantly slower under the same intense light.

Subsequently, the reporter carried out the experiment in the company's two cars on the same road. One was covered with a new cooling material, and the other was directly exposed to the sun. Reporters placed mercury thermometers in two cars at the same time. After 5 minutes, the thermometer showed 41℃ and 58℃, respectively. The new material has obvious heat insulation and cooling effect.

Da-qing li, general manager of the company is introduced, this cool fabrics based on the world's leading radiation (system) cold material technology, solar energy reflectivity of 76% to 85%, the infrared thermal emission rate is above 90%, uv data UPF 50 +, UVA < 1%, mainly through cooling technology, completely zero carbon emissions, and with independent intellectual property rights. At present, the technology has 4 invention patents, 8 utility model patents.

In addition to applied to production of car covers, awning, tents, awnings, umbrellas and other products, the technology can be applied to the outdoor public space of sun protection and other fields, can be widely used in large construction, industrial plant, grain storage, electricity, communications, and film, coating, metal plate (tile) radiation () cold materials, such as series of products, Realize continuous cooling and energy saving under direct sunlight.

It is reported that Jiangsu He Chao new material technology Co., Ltd. r & D and production center is located in Wujiang Fuhua Weaving Co., LTD., and Ningbo Ruiling New energy technology Co., Ltd. joint venture, registered in June this year. Among them, Ruiling New Energy Company is also the drafting unit of the national radiation induced (production) cold film group standard (T/ZZB2304-2021). As one of the radiation cooling technology enterprises in China, Hechao New Material will further extend around the textile fields such as yarn and weaving, with the mission of leading the industry standardization, building the industrial ecological chain, and fostering the rapid development of upstream and downstream enterprises. Hechao New Material is committed to contributing to the goal of "carbon peak and carbon neutrality" as a private enterprise in Wujiang.
