Chromatic glass belongs to special glass class, also known as heat-absorbing glass, refers to the glass with different colors after adding colored art glass colorant.   Colored glass absorbs the sun's visible light, usually blocking about 50 percent of the sun's radiation.   Weaken the intensity of sunlight, the glass absorbs the sun's rays at the same time the temperature increases, easy to produce thermal crack.   For example, 6mm thick blue glass can only penetrate 50 percent of the solar radiation, brown, bronze heat absorption glass can only penetrate 25 percent of the sun. Colored glass, shading effect is good, no care, look upscale. The color glass is also subdivided into grey glass, green glass, blue glass, tea glass, black glass, Finished color glass can also be combined processing, such as hollow glass can use gray glass and white glass, personalized customization. Glass color on the new, keep up with the market trend, can meet the public's different preferences.(1) Absorption of solar radiant heat For example, 6mm thick transparent float glass, the total transmission heat under the sun is 84%, and the total transmission heat of colored glass under the same conditions is 60%. The color and thickness of colored glass are different, and the absorption degree of solar radiant heat is different. (2) Absorption of solar visible light Reduce the intensity of sunlight, play the role of anti-glare (3) With a certain degree of transparency Can absorb a certain amount of ultraviolet light. Chromatic glass material has been applied in many places, not only in the interior decoration, in the car glass, generally installed dark glass, sunglasses are also colored glass lenses. As well as a variety of decorative lampshades, in order to brilliant color, will be installed with colored glass lampshades, colored glass has been applied in many places, in our life, colored glass everywhere.1. Used for building doors and Windows, partition, intelligent building 2. Can automatically control the solar radiation energy into the room, so as to reduce energy consumption, improve indoor natural lighting conditions, with anti-peep, anti-glare effect.
