Solar ultra-white float photo-thermal glass and manufacturing method thereof

Abstract

The invention relates to the technical field of glass, and discloses solar ultra-white float photo-thermal glass, which is characterized by comprising the following raw materials in parts by weight: 68-75 wt% of SiO2; al2O3: 0.3 wt% to 2.0 wt%; na2O: 12 wt% to 15.5 wt%; k2O: 0 wt% to 2 wt%; caO: 5 wt% to 11 wt%; sb2O3: 0.05 wt% to 0.5 wt%; mgO: 1 wt%-5 wt%; li2O: 0.1 wt% to 2.0 wt%; fe2O3: 1t; 0.01 wt% of the total weight; sO3: 0 wt% to 1 wt%; raw materials for forming the components comprise low-iron quartz sand, dolomite, limestone, aluminum hydroxide, mirabilite, sodium carbonate, potassium carbonate and sodium pyroantimonate. On the basis of common low-iron sodium-calcium silicate, various conventional sodium-calcium silicate components are optimized, the contents of CaO, MgO and Al2O3 are limited, and meanwhile, a small amount of new components such as Li2O, K2O and Sb2O3 are introduced into the glass to meet the requirements of a photo-thermal power generation glass substrate, so that the requirements of high transmittance and high reflectivity are met; the requirements of the photo-thermal power generation glass substrate are met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a solar ultra-white float photothermal glass and a manufacturing method thereof. Background technique [0002] Solar thermal power generation refers to the use of large-scale arrays of parabolic or dish-shaped mirrors to collect solar thermal energy, provide steam through heat exchange devices, and combine the technology of traditional steam turbine generators to achieve the purpose of generating electricity. The use of solar thermal power generation technology avoids the expensive silicon photoelectric conversion process, which can greatly reduce the cost of solar power generation; moreover, this form of solar energy utilization has an incomparable advantage over other forms of solar energy conversion, that is, the use of solar energy. The hot water can be stored in a huge container, and it can still drive the steam turbine to generate electricity a few hours after the sun goes do...
