Endothermic glass
close Heat absorbing glass includes gray, brown, blue, green, bronze, bronze, pink and golden yellow. At present, China mainly produces the first three colors of endothermic glass. The thickness is 2, 3, 5 and 6 mm. The heat absorbing glass can also be further processed into polished, tempered and laminated insulating glass. Heat absorbing glass can also block sunlight and air conditioning, making the room warm in winter and cool in summer. Compared with ordinary plate glass, heat absorbing glass has the following characteristics: 1. Absorbing solar radiation heat, such as 6mm thick transparent float glass, the total heat transmission under sunlight is 84%, while under the same conditions, the total heat transmission of heat absorbing glass is 60%. The absorption of solar radiation heat varies with the color and thickness of the heat absorbing glass. 2 Absorption of visible sunlight weakens the intensity of sunlight, playing the role of anti glare. 3 It has certain transparency and can absorb certain ultraviolet rays. Due to the above characteristics, heat absorbing glass has been widely used in doors, windows and exterior walls of buildings, as well as as windscreens of cars and ships, playing the role of heat insulation, anti glare, lighting and decoration. Absorb part of the sun's visible light to soften the dazzling sun and prevent dazzle. See the table below for the visible light transmittance and direct sunlight transmittance required by China for 5mm heat absorbing glass with different colors. Color visible light transmittance/% direct sunlight transmittance/% tan ≥ 45 ≤ 60 gray ≥ 30 ≤ 60 blue ≥ 50 ≤ 70
