Problems solved by technology

At present, the production of dark green glass is based on the production process of ordinary glass. Colorants are added to the main glass components. Under the action of colorants, ordinary white glass becomes dark green, but the purity of the color is not easy Controlled, prone to color unevenness

Abstract

Percents of colorants which add to basic glass in total weight is 0.001-0.002(CoO), 0.005-0.008(NiO), 0.01-0.02(SeO), 0.3-0.5(Fe2O3), 0.03-0.06(Cr2O3), and in melting process, (1)melting temperature is between 1560 and 1570 and should content;(2) mechanical milling. The invention adopts high temperature and mechanical mill, and produces homochromy crystal dark green glass.

Description

Technical field: [0001] The invention relates to a production method of dark green glass. Background technique: [0002] Dark green glass has the ability to regulate the transmission of sunlight and heat radiation, and has an elegant color and soft light, which can be effectively used in heat insulation, decoration and other fields. At present, the production of dark green glass is based on the production process of ordinary glass. Colorants are added to the main glass components. Under the action of colorants, ordinary white glass becomes dark green, but the purity of the color is not easy control, prone to color unevenness. Invention content: [0003] The object of the present invention is to provide a method for making dark green glass that can effectively prevent color impurity. [0004] In order to achieve this purpose, the technical scheme adopted in the present invention is: add coloring agent in bulk glass composition, the weight percent of each component of colo...
