Composition of colored glass precautions for selec

  • Detail

Colored glass, also known as endothermic glass, can generally block about 50% of sunlight radiation. For example, 6mm thick blue glass can pass through 50% of sunlight, while brown and bronze endothermic glass can only pass through 25% of sunlight

colored glass has a wide variety of models and uses. Moreover, colored glass can play the role of sterilization, disinfection and deodorization in urban residential buildings. Half of the sunlight is blocked by these colored endothermic glass, which is not worth the loss. Therefore, colored glass should be used with caution in home decoration, even if it has many benefits. The following editor will introduce the composition of colored glass and the precautions for the selection of colored glass

composition of colored glass

colored glass is ordinary glass added with colorants, such as MnO2, which is purple; COO and Co2O3 are burnt purple; FeO and K2Cr2O7 are burned green; CDs, Fe2O3, Sb2S3, burnt yellow; Aucl3 and Cu2O burn red; The mixture of CuO, MnO2, COO and Fe3O4 is burned black; CaF2 and SnO2 are burnt to milky white. Use colloidal colorants, such as gold, silver, copper, selenium, sulfur, etc., colloidal au&mdash& mdash; red Colloidal ag&mdash& mdash; Yellow makes tiny particles suspended in the glass body, making the glass colored

harm of colored glass

1. Colored glass has poor light transmittance, which will pawn at least half of the sunlight that should have played the role of disinfection, sterilization and deodorization

2. In summer, many families will install screen windows. The light transmittance of screen windows is about 70%. If colored glass is added, the light transmittance is only 35%, which will affect the indoor lighting requirements

3. The light that people see everyday is synthesized by seven color light, infrared, ultraviolet and other light. When sunlight passes through ordinary glass, people receive full-color light, but colored glass does not. For example, when sunlight passes through sapphire blue glass, it is similar to blue light “ Complementary ” The red light and orange light will be absorbed by the glass, leaving only the light with a shorter wavelength, which will cause the color distortion of the object. Living in such an environment for a long time will seriously affect people's visual resolution, and even cause spiritual changes and personality distortion. It is particularly harmful to children in the growth and development period, because their retinas cannot be stimulated by panchromatic light, which is very likely to lead to incomplete visual development

precautions for the selection of colored glass

1. Colored glass belongs to special glass, which is called endothermic glass, and can usually block about 50% of the sunlight radiation. For example, 6mm thick blue glass can only pass through 50% of the solar radiation; Brown and bronze heat absorbing glass can only pass through 26% of the sunlight. Therefore, heat absorbing glass is suitable for doors and windows or external walls of buildings in hot areas that need both lighting and heat insulation, as well as trains, cars, ships or windshield glass. In this way, it can not only heat insulation and anti glare, but also create a beautiful cool atmosphere. However, in the urban residential buildings, the sunlight that can sterilize, disinfect and deodorize is blocked by half by these colored endothermic glasses, which is not worth the loss

2. During the decoration process, it was found that some residents even sealed the balcony with colored heat absorbing glass. This balcony is the only place upstairs that can talk with nature and accept the gifts of nature without going downstairs. It is beneficial to the health of the elderly and infants. The balcony should not be closed, let alone decorated with colored glass. If people live in blue gray, tawny and other weak light environment for a long time, the quality of indoor vision will inevitably be reduced, which is easy to make people physically and mentally exhausted, lack of rest, and will have adverse effects on health

3. Add colorants, namely various metal oxides, to the raw materials to make clear glass with red, green, yellow, blue, gray and other colors. Transparent glass, also known as decorative glass, can be made by spraying colored glaze on one side of flat glass with a certain shape and baking it. This kind of glass has the characteristics of corrosion resistance, erosion resistance, easy cleaning and can be assembled into patterns. It is suitable for surface decoration of parts requiring high corrosion prevention, antifouling and beautification

4. However, the sunlight that can play the role of sterilization, disinfection and deodorization in residential areas is not desirable to be blocked by these colored heat absorbing glasses. And long-term living in blue gray, brown and other weak light environment, the quality of indoor vision will inevitably decline, which will have a negative impact on health

editor's summary: This is the introduction about the composition of colored glass and the precautions for the selection of colored glass. I hope it will be helpful to you. If you want to know more, you can pay attention to information
