Abstract

The invention discloses a light diffusion glass. The light diffusion glass comprises the basic components of common soda-lime silicate glass, the content of sodium oxide in the basic components of common soda-lime silicate glass is reduced by 1.5wt.%-2.8wt.%, and at the same time, 0.5wt.%-1wt.% of a new component barium oxide is added. Compared with the prior art, the light diffusion glass provided by the invention is machined without changing the existing rolled glass production line equipment, the content of sodium oxide in the components of common soda-lime silicate rolled glass is reduced,the component barium oxide is added, the light diffusion glass has higher light transmittance, better chemical stability, higher thermal shock resistance, better hardness and wear resistance, and higher strength than ultra-white rolled glass, and more importantly, the light diffusion glass increases light scattering and transmission, and while shading a light source and a dazzling light source, also can make the light transmitting the glass become softer and more uniform, thus reaching light-transmitting and non-transparent comfortable effects.

Description

technical field [0001] The invention relates to the technical field of glass production and processing, in particular to a light-diffusing glass. Background technique [0002] As of September 2017, there are about 2.1 million hectares of greenhouses in China (among them: 1.37 million hectares of the first-generation plastic greenhouses and 730,000 hectares of the second-generation ordinary glass greenhouses). These greenhouses are small in scale and occupy a large area (low land utilization rate), poor lighting performance, low level of mechanized cultivation technology, low risk of resisting natural disasters and pests and diseases, harsh planting environment, and serious food environmental protection problems. In order to further meet people's needs for pollution-free and health-care food consumption, the country is now starting to develop the third-generation greenhouse—a solar organic plant factory greenhouse workshop that adopts "Dutch greenhouse agriculture + Israeli p...
