1. Where is the glass needed in our lives?
The Glass has excellent performance and can be used in a variety of applications. In the interior decoration, you can use tinted glass and hot-melt glass, and the style is changeable. In the occasion where you need to protect personal safety, it is suitable to use safety glass such as tempered glass and laminated glass. And for the window and door.
If you need to adjust the brightness and protect privacy, you can use frosted glass and dimming. Glass, convenient and durable. For information on colored glass (Tinted glass), please see below.
Colored glass is added to ordinary glass, such as adding MnO2 to purple; CoO, Co2O3 is burned to purple; FeO, K2Cr2O7 is burned green; CdS, Fe2O3, Sb2S3 are burnt yellow; AuCl3, Cu2O are burnt red; CuO, A mixture of MnO2, CoO, and Fe3O4 is fired in black; CaF2 and SnO2 are calcined in milky white.
The amount of coloring, the melting time and the melting temperature will affect the depth of the burnt color to varying degrees. A colloidal colorant such as gold, silver, copper, selenium, sulfur, or the like is used to suspend very small particles in the vitreous to color the glass. No flux is added to the colorant during the firing process.
Colored glass is a solid sol, and solid sol refers to a sol formed by using a solid as a dispersing agent.
1. What functions can be used for colored glass?
1) Absorption of solar radiant heat
For example, a transparent float glass of 6 mm thickness has a total permeation heat of 84% under sunlight, and the total permeation heat of the colored glass under the same conditions is 60%. The color and thickness of colored glass are different, and the degree of absorption of solar radiant heat is also different.
2) Absorption of solar visible light
Reduces the intensity of sunlight and acts as an anti-glare.
3) has a certain transparency
Can absorb certain ultraviolet rays.
Low E reduces the amount of direct solar energy from entering the building. Before the development of low E coatings, architects relied on tinted (heat-absorbing glass) or reflective coating to reduce solar energy transmission. Tinted glass almost always requires heat-treatment to reduce potential thermal stress and breakage and tends to reradiate the absorbed heat.
Reflective coating are effective are reducing heat gain but also reduce visible light transmission. Low E coating reflect solar energy away from the glazing, often without requiring heat-treatment, and generally have lower visible light reflect.
