New float glass with high light transmission and high heat performance

A piece of glass with a thickness of 6 mm and a pale blue luster has no film or any obstruction. It can block 90% of infrared light under strong sunlight, while maintaining a high transmittance of 70%. .... Reporter saw in the laboratory of Nanjing Anda Glass Technology Co., Ltd. on the 14th that a new high-transmission and high-insulation float glass with independent intellectual property rights was successfully developed, and the energy-saving index set a new world record and passed the Ministry of Housing and Urban-Rural Development. Technical appraisal of building materials federation.

The new insulated float glass adopts a unique bulk addition formula and process. By adding an oxide compound compounded composite material in the glass melting process, it has high light transmission and high heat insulation performance, and the heat insulation effect. 40% more than traditional insulating glass.

"The unique feature is that while transmitting more than 90% of the near-infrared rays that generate heat, the visible light transmittance can be maintained above 70%, and the light-to-heat ratio is greater than 1.36. This indicator is leading at home and abroad." Nanjing Anda Total According to manager An Yongfeng, this technology has been successfully developed for three years. Compared with similar products monopolized by American companies, this technology does not require new production lines. It can be produced by adding composite materials to the kiln of traditional glass enterprises, which greatly reduces production. The cost has broken through the process bottleneck and is a major innovation in glass technology at home and abroad.

At present, this new type of light-transmissive insulating glass has been successfully put into operation on the No. 1 line of Kunming Haikou Float Glass Production Base of Yunnan Yukai Energy Saving Technology Co., Ltd., with a daily output of 520 tons of float glass.
