The hottest transparent thermal insulation glass c

Transparent thermal insulation glass coating puts on "thermal insulation jacket" for windows. Yesterday, the 13th China East West cooperation and investment and Trade Fair opened in Xi'an, with delegations from 31 provinces, autonomous regions, municipalities directly under the central government and Xinjiang production and Construction Corps participating

in the Shanghai exhibition area, On June 27 last year, Shenzhen water new materials Co., Ltd. (securities referred to as "water shares") In the sea exhibition area, apart from the display boards, the booth of Fujia New Material Technology Co., Ltd. is different from the general construction site: there is no scaffold for traditional building construction at the site, and there is a small Western-style house with red roof and white walls. When the exhibitor turned on the two infrared lights installed in front of the model, the temperature counts in the two rooms of the small villa began to rise. However, the rising range of these two thermometers is obviously different, one fast and one slow, and finally the temperature difference between the two buildings reaches 7 degrees Celsius

Wei Yong, the technical director of the company, said that one window glass of the building was painted with "transparent thermal insulation glass paint", while the other glass was not painted, which is the mystery. According to reports, this coating is composed of nano semiconductor materials. In summer, semiconductor materials block infrared rays from entering the sun through free electron oscillations; In winter, it can block the emission of indoor infrared rays, so as to achieve the effect that the building is warm in winter and cool in summer. By making semiconductor materials into nanoscale, the paint can "release" all visible light in sunlight and keep the window glass transparent

in addition, the transparent heat-insulating glass coating can also block some ultraviolet rays, which is beneficial to human body. Wei Yong said that compared with some imported thermal insulation films, under the same light transmittance, the nano coating has a greater barrier to solar energy, and the effect of controlling indoor temperature is more obvious. In summer, it can reduce the room temperature by 2-7 degrees Celsius, and in winter, it can increase the room temperature by 2.5-5 degrees Celsius, saving the amount of air conditioning and heating equipment

it is reported that last month, nearly 3000 square meters of glass exterior walls of Shanghai Science and technology museum were covered with this "thermal jacket". As a special project of Expo science and technology, it will also be used for the construction of the German Pavilion

in order to ensure the continuity of sampling and data transmission

under the internal economic cycle, China Chengdu Construction Expo in April 2021 will talk with you. 1. We must adjust the new opportunities of the focus industry

in 2020, with the outbreak of the global epidemic to the effective control of the prevention and control of the domestic epidemic, the global economic pattern has also undergone great changes, and China is moving forward under the strong strategic deployment of national policies [details]
