Embodiment Construction

[0004] 1. According to the ingredients of the above batch, ordinary transparent glass batch is used as the basis to weigh 1 to 2 kg (raw meal containing different concentrations of colorants), the weighing accuracy of the raw meal is kept within 1 gram, and the weighing accuracy of the colorant is At 0.001 grams.

[0005] 2. Melt in an electric furnace at a temperature above 1550°C, and at the same time, the clarification time should not be less than 4 hours. In order to solve the problem of stripes, after the glass is melted, stir at regular intervals, usually every 15 to 30 minutes, stir 3 to 5 times each time, and stir continuously for more than 4 times.

[0006] 3. The mold is used for molding, so the model must be heated in advance, and the heating temperature of the mold is 300-500 degrees. After the glass is melted and clarified, the mold is removed from the heating furnace, and then the clarified glass is poured into the mold and quickly shaped.

[0007] 4. After the...

Abstract

A green glass able to strongly absorb ultraviolet ray and infrared ray is characterized by that the colouring agent is used as part of raw materials for ordinary NaSiCa glass. Said colouring agent contains Fe2O3 (0.5-0.9 %), TiO2 (0.2-0.7%), and CeO2 (0.05-0.15%). Its advantages are low ultraviolet transmissivity (less than 17%), low infrared transmissivity (less than 28%) and high viual light transmissivity (more than 70%).

Description

technical field [0001] The invention relates to a coloring agent added to common float glass components, so that the glass can absorb strong ultraviolet rays and infrared rays, and its color is green. Background technique [0002] With the continuous improvement of people's awareness of energy saving and the continuous development of the automobile industry, new energy-saving and consumption-reducing products are increasingly adopted by the automobile industry. The sunlight injected into the car increases the temperature inside the car on the one hand, On the other hand, the ultraviolet rays in the sun accelerate the erosion of plastics, leather and other decorative materials in the car. At present, the glass used in automobiles in the market cannot block strong ultraviolet rays and infrared rays, especially in summer, which is not good for human health. Contents of the invention [0003] The purpose of the present invention is to provide a kind of doping several kinds of ...
