Colored glass components tinted glass selection considerations

There are various types of colored glass, and their uses are also very wide. In addition, colored glass can play the role of sterilization, disinfection and deodorization of sunlight in buildings in urban residential areas. It is noteworthy that these colored heat-absorbing glasses are half-empty. Therefore, colored glass must be used carefully in home decoration. It has many advantages. The composition of colored glass and the selection of colored glass are introduced in the following section.

Composition of colored glass

Common glass colorants are added to colored glass, such as MnO2 in purple; CoO and Co2O3 are burnt into purple; FeO and K2Cr2O7 are fired green; CdS, Fe2O3, SB2S3, burnt yellow; AuCl3, Cu2O red-hot; Burn the mixture of MnO2, CoO and Fe3O4 into black; CaF2 and SnO2 are milky white. Colloidal colorants such as gold, silver, copper, selenium, sulfur, etc., colloidal gold red and colloidal silver yellow are tiny particles suspended in the glass, which are used to color the glass.

Harm of colored glass

1. The transparency of colored home decor glassware is poor. At least it should be disinfected, sterilized and deodorized in the sun.
2. In summer, many families will install screens. The transmittance of the screen is about 70%. If they are equipped with colored glass, the light transmittance will be only 35%, which will affect the indoor lighting requirements.
3. The light people see every day is composed of seven colors of light, infrared light and ultraviolet light. When sunlight passes through ordinary glass, people will receive full-color light, while colored glass will not. For example, when the sun passes through the sapphire blue glass, the red light and the orange light "complementary" with the blue light will be absorbed by the glass, leaving only the short-wavelength light, causing the color distortion of the object, and living in such an environment for a long time. It will seriously affect people's visual resolution, and even cause mental changes and personality distortion. It is particularly harmful to young children in the growth and development stage, because their retina is not stimulated by full-color light, and it is easy to cause vision hypoplasia.

Colored glass selection considerations

1. Colored glass belongs to the category of special mouthblown glass, called heat-absorbing machine made glass, which usually blocks about 50% of the sunlight radiation. For example, a 6mm thick blue glass can only penetrate 50% of the solar radiation; Brown and bronze heat-absorbing glass can only penetrate 26% of the sunlight. Therefore, heat-absorbing glass is suitable for building doors, windows or exterior walls as well as trains, cars, ships or windscreens in high-temperature areas requiring lighting and heat insulation. In this way, it not only has the effect of heat insulation and anti-glare, but also creates a beautiful cool atmosphere. However, in urban housing, the sunlight that can sterilize, sterilize and deodorize is blocked by these colored heat-absorbing glasses. This is actually worth it.
2. During the renovation, it was found that some residents even closed the balcony with colored heat-absorbing glass. This balcony is the only place where you can talk with nature without going downstairs to accept the gift of nature. The balcony beneficial to the elderly and infants should not be closed and cannot be decorated with colored glass. If people live in low-light environment such as blue-gray or brown for a long time, the indoor visual quality will inevitably decrease, which will make people feel physically and mentally tired. Rest is not enough, which will have adverse effects on health.
3. Add colorants, namely various metal oxides, into the raw materials to make transparent glass with red, green, yellow, blue, gray and other colors. On the side of a certain shape of flat glass, spray a layer of colored glaze and bake to make transparent glass, also known as decorative glass. This kind of glass has the characteristics of corrosion resistance, corrosion resistance, easy cleaning and patterning, and is suitable for surface decoration with high requirements for corrosion prevention, stain prevention and beautification of parts.
4. However, it can play the role of sterilization, disinfection and deodorant in residential areas. It is not advisable to be covered by these colored heat-absorbing glasses. In addition, living in low-light environments such as blue-gray and brown for a long time, the indoor visual quality will inevitably decline, which will have adverse effects on health.
