Embodiment Construction

[0014] The formula and the manufacturing process of the green float glass are further illustrated below mainly in conjunction with specific examples.

[0015] The green float glass in this example has the following composition formula:

[0016] SiO2: 70.0% to 75.0%; Al2O3: 0% to 3.0%; CaO: 8.0% to 11.0%; MgO: 2.0% to 4.8%; Na2O: 13.0% to 16.0%; K2O: 0.3% to 0.8%; SO3: 0.2% to 0.23%; Fe2O3: 0.570% to 0.630%; in addition, green float glass also contains FeO, which accounts for 24% to 27% of the total mass of FeO and Fe2O3.

[0017] The visible light transmittance of the green float glass in this embodiment is 76%-78% at a standard thickness of 5mm, and has a total sunlight transmittance of less than 50% and an ultraviolet light transmittance of less than 28%. Because the glass can realize the selective absorption of the ultraviolet spectrum in the solar spectrum, and achieve the purpose of filtering the harmful rays in the sunlight, and because it is unique in the type and quan...

Abstract

The invention relates to a green float glass and a production method thereof. The green float glass comprises 70.0 to 75.0% of SiO2, 0 to 3.0% of Al2O3, 8.0 to 11.0% of CaO, 2.0 to 4.8% of MgO, 13.0 to 16.0% of Na2O, 0.3 to 0.8% of K2O, 0.2 to 0.23% of SO3 and 0.570 to 0.630% of Fe2O3. The green float glass also contains FeO which accounts for 24 to 27% of the total mass of Fe2O3. Through introduction of the colorant Fe2O3 powder on the basis of a formula for common white float glass, no extra colorant is needed and special clarification equipment is not needed. The production method for the glass is simple, controllable and stable in process; process adjustment is convenient and easy; production cost is lower; and the prepared glass can be changed in color, transmittance and reflectivityso as to meet the requirements of market customers.

Description

technical field [0001] The invention relates to the field of glass production, in particular to a green float glass mainly used in the automobile industry and a manufacturing method thereof. Background technique [0002] With the development of industrial production technology and the continuous improvement of people's material living standards, the development of the automobile industry has been very rapid in recent years, and the popularity of automobiles has continued to rise. The development of the automobile industry has also paid more and more attention to the safety, appearance and environmental protection of automobiles. Automobile glass is an important indicator of automobile beauty. Therefore, with the expansion of market demand, the application prospect of high-grade automobile glass is very broad. The transmittance, reflectivity and color of automotive glass are obviously different from ordinary float white glass. The traditional float glass sold in the market is...
