Embodiment 1

[0055] The main components of the above-mentioned blue-green heat-absorbing glass composition are formulated according to the following ratio: SiO 2 75.4%, CaO 9.7%, Na 2 O 10.7%, MgO 1.05%, Al 2 o 3 0.5%, the colorant components include total iron 1.18% (of which ferrous iron is 0.24%), CoO 16ppm, Cr 2 o 3 3.3ppm, CuO 0.38%, ZnO 0.55%, TiO 2 0.46%. According to the batching ratio of the glass composition, the raw materials are put into the kiln head silo, enter the melting furnace, and go through processes such as melting, clarification, molding, annealing, cutting, and boxing to produce blue-green glass, and its visible light transmittance is 63%. , The total solar transmittance is 34.5%. Use X-RITE TM The color difference measured by the SP-62 portable color difference meter is: L * The value is 33.65; a * The value is -4.61; b * The value is -0.71.

Embodiment 2

[0057] The main components of the above-mentioned blue-green heat-absorbing glass composition are formulated according to the following ratio: SiO 2 70.2%, CaO 10.4%, Na 2 O 13.0%, MgO 2.56%, Al 2 o 3 0.7%, the colorant components include total iron 1.05% (of which ferrous iron is 0.28%), CoO 7ppm, Cr 2 o 3 12.2ppm, CuO 0.34%, ZnO 0.40%, TiO 2 1.22%. According to the proportion of the glass composition, the raw materials are put into the kiln head silo, enter the melting furnace, and go through processes such as melting, clarification, molding, annealing, cutting, and boxing to produce blue-green glass, and its visible light transmittance is 61.6%. , The total solar transmittance is 31.9%. Use X-RITE TM The color difference measured by the SP-62 portable color difference meter is: L * The value is 35.01; a * The value is -4.45; b * The value is -0.11.

Abstract

The heat absorbing blue-green glass composition includes main glass components and colorant components. The main glass components include SiO2 68-77 (in wt%, the same below), CaO 7-17, Na2O 12-21, MgO 1-4 and Al2O3 0.2-2. The colorant components include Fe2O3 0.95-1.35 wt%, FeO 0.15-0.35 wt%, CoO 6-20ppm, Cr2O3<15ppm, CuO 0.05-0.4 wt% and ZnO 0.02-0.85 wt%. The heat absorbing blue-green glass composition has the features of capacity of absorbing infrared radiation, pure color and high brightness.

Description

【Technical field】 [0001] The invention relates to a glass, in particular to a blue-green heat-absorbing glass composition, which is mainly applied to the construction field. 【Background technique】 [0002] In recent years, with the improvement of people's awareness of environmental protection, more and more attention has been paid to energy-saving and consumption-reducing products, and glass products are no exception. Adding various colorants to the glass composition, these colorants are generally colored metal oxides, can make the glass plate have a certain ability to absorb ultraviolet rays and / or infrared rays. This is the commonality of colored glass with colorants added. [0003] On the other hand, as people's aesthetic requirements are getting higher and higher, glass is also transitioning from white transparent glass to various colors. Various colors can be presented by adding or matching different colorants to the glass composition. According to data retrieval, mo...
