Insulated glass is a performance glass that can be divided into three kinds: XRB1, XRB3, and coated insulated glass. The three kinds of glass are slightly blue-green and close to colorless. Among them, XRB1 is phosphate-absorbing glass; XRB3 is silicate-absorbing glass; and coated thermal insulating glass is coated with thermal insulating nanopowder to block heat.
Heat-insulating glass can be generally classified into two categories according to the different requirements of use. One category is that which can absorb infrared light in a large amount, and the glass is colorless; that is, this glass should have a high smooth transmission curve in the visible region from 400 mL to 76 mL. For example, in the film baking shell, film projection, slide projection, color printing, and other aspects of the glass used, it is necessary to isolate the heat generated by the light source to protect the film while also ensuring that color reproduction is not affected. In terms of composition, this type of glass generally belongs to the phosphate glass system, another category that requires the absorption of a portion of the infrared, and glass is also permitted to carry a portion of the color. For example, the windows of buildings in hot areas, surgical shadowless lamps and car windshields, and other glass. This type of glass generally belongs to the silicate glass system.
They do not significantly absorb visible light but rather a large amount of heat-producing near-infrared light, with XRB1 and XRB3 having the most pronounced performance characteristics in cases where high light intensity is required and heat is to be removed. And coated insulated glass can be used in buildings to directly reduce the temperature, the temperature difference between about 3 ℃ - 6 ℃.
Bus windows using heat-absorbing (sun-shading) glass, when used in the summer, can improve the temperature and humidity conditions in all types of buses, with the best effect in air-conditioned buses. Air-conditioned buses, in addition to improving the travel conditions of passengers, can also greatly reduce the heat load, thus reducing power consumption, reducing the working time of the air conditioner, and helping to ensure the service life of the air conditioner. Heat-absorbing glass has a high ability to absorb infrared rays (whose wavelength ranges from 800 to 3000Nm) in limited light, and visibility is practically unchanged.
