The latest colorless transparent UVA glass bottle
2022-08-21- Detail
New colorless and transparent UVA glass bottle
at present, the emergence of a colorless and transparent UVA glass bottle that can block ultraviolet rays, with an annual production capacity of about 100000 tons in phase I, has attracted widespread attention. The biggest feature of glass bottle is that it can clearly see the transparency of its contents. But because of this, external light can easily pass through the container, causing the content material to become and deteriorate. For example, when beer is exposed to the sun for a long time, it will produce peculiar smell and discoloration. Foreign experiments show that when the wavelength of light is 406nm-500nm, beer will fade until it stinks
its production method is, on the one hand, by adding ultraviolet absorbing metal oxides to the glass, and at the same time, using the color complementary effect, adding some metals or their oxides to make the colored glass fade
for u with a thickness of 3.5mm, because its two large upstream chemical projects in the Gulf of Mexico and Saudi Arabia were fully completed and put into operation last year, the random sampling test of light transmittance of VA glass and ordinary glass with a wavelength of 330nm showed that ordinary glass was 60.6%, while UVA glass was only 2.5%. The sunlight exposure experiment of ordinary glass bottle and UVA glass bottle wine also showed that the discoloration degree and taste deterioration degree of the former wine were much higher than the latter
