Light blue energy-saving environmental-protection transparent glass for adsorbing ultraviolet rays and infrared rays

Abstract

The invention relates to light blue energy-saving environmental-protection transparent glass for adsorbing ultraviolet rays and infrared rays, which is formed by that Fe2O3 and CeO2 are added in dry quartz sands and other auxiliary materials, and then the glass is directly fired under the high-temperature melting and low-temperature annealing processes; the ferrous ions in the glass can strongly adsorb middle and far infrared rays, and cerium ion therein can strongly adsorb the ultraviolet rays; Visible light transmittance of the glass with 6mm is more than 70 percent, the transmittance of the infrared rays with 780nm-3000nm and 44 percent of the sun heat can be reduced to below 1 percent, the transmittance of the ultraviolet rays with 200nm-390nm and 14 percent of the sun heat is reduced to below 0.01 percent, and the ray transmittance is low; the invention has simple processing technique, and the cost is less than one third of Low-E glass, and the disadvantages of the Low-E glass are overcome; the glass is mainly applied to building glass and automobile glass products, so as to meet the energy-saving and pollution-reduction requirements of the building glass and automobile glass.

Description

technical field [0001] The invention belongs to the field of glass production, and in particular relates to a light blue energy-saving and environment-friendly transparent glass that absorbs ultraviolet rays and infrared rays. It is mainly used in architectural glass and automotive glass products, and can meet the energy-saving and emission-reduction requirements of architectural glass and automotive glass. Background technique [0002] In recent years, Low-E glass has been popular in architectural glass. Low-E glass can greatly reduce the transfer of indoor heat energy to the outside caused by radiation, and achieve the ideal energy-saving effect; Low-E glass has more than 80% visible light transmission to sunlight. Ratio, while the reflectance is very low, the optical performance is greatly improved, and the appearance is more transparent and clear when viewed from the outside. [0003] There are also problems with Low-E glass: 1. Secondary processing of the glass is neces...

AI Technical Summary

Problems solved by technology

[0003] There are also problems with Low-E glass: 1. Secondary processing of the glass is necessary, the coating production process is very complicated, the coating equipment is expensive, and the energy consumption is also high, resulting in increased production costs; 2. The coating layer is highly reflective to mid- and far-infrared rays. Instead of absorbing mid- and far-infrared rays, a large amount of heat in the sun will accumulate outside in summer, and the outdoor temperature will rise a lot; 3. In order to protect the coating layer, Low-E glass needs to be sealed into a hollow structure with rubber strips. On the one hand, the thickness of the glass is increased. It also increases the consumption of steel for doors and windows. On the other hand, as time goes by, the rubber strip will inevitably age or even fall off earlier than the coating, making the coating lose its protection. The coating will quickly oxidize and age when exposed to the air, resulting in Low-E glass failure

[0004] A patent search found that PPG Industries Ohio Corporation of the United States applied for a patent entitled "Infrared and Ultraviolet Radiation Absorbing Blue Glass Composition" (Patent No.: 98810129.7), and China Shanghai Yaohua Pilkington Glass Co., Ltd. applied for a patent named " Green Glass with Strong Absorption of Ultraviolet and Infrared (Patent No.: 03117080.3). The former patented product is used for architectural glass and automotive glass, and the latter is used for automotive glass. The technical indicators of these two patented products are not ideal in terms of energy saving and environmental protection. , 780nm-3000nm infrared and 200nm-390nm ultraviolet transmittance are high
