The mild air pollution of the glass curtain wall refers to the use of coated glass on the curtain wall of large-rise properties. When direct sunlight and skylight are irradiated on to the glass area, the specular reflection (ie, specular reflection) of the glass. And the resulting reflected glare.

Gentle pollution is the assassin of accidental visitors accidents. A glass walled constructing stands like a enormous mirror with a width of tens of meters and a height of nearly 100 meters. It displays the visitors situations and site visitors lights (even a number of reflections).
China cheap aluminium profile mirrored light enters the auto at large speed, which will lead to unexpected short-term blindness and visual illusion, which will include the driver’s vision in an instant, or make him truly feel dizzy and significantly endanger the visual perform of pedestrians and motorists. The glass curtain walls built about the household area will replicate the surrounding structures. According to optical specialists, the reflected gentle of mirrored developing glass is stronger than that of sunlight, and its reflectivity is as substantial as 82% to ninety%. The light-weight is almost totally mirrored, which drastically exceeds the range that the human entire body can bear. In the summer time, the solar is reflected into the dwelling space. The strong glare is the most damaging to the first very good atmosphere in the room. It also raises the room temperature by an common of four °C to 6 °C. Individuals who perform and reside in a white brilliant and polluted setting for a prolonged time may simply guide to diminished eyesight, dizziness, insomnia, palpitations, loss of hunger and depression, and other indicators of neurasthenia, which may possibly lead to alterations in regular physiological and psychological problems. Prolonged-term will induce specific ailments. Therefore, the Condition Environmental Security Administration has acquired problems about gentle pollution all in excess of the region each 12 months, which has attracted the focus of related point out departments.
Light-weight pollution is produced under the adhering to distinct conditions: (one) the use of big locations of higher reflectivity coated glass (2) in a specific route and at a specific time (3) the degree of light-weight air pollution and the route, position and height of the glass curtain wall Have a shut partnership. Simply because the human’s angle of look at has the finest affect in an angle of ±15 degrees close to 2 meters, the intensity of gentle reflection is inversely proportional to the square of the length from the reflector to the human eye.
In modern years, governments and pertinent academic teams have attached wonderful relevance to the concern of mild air pollution, and have successively released a series of complex paperwork, specifications and decrees to management mild air pollution. China has also connected excellent significance to the issue of curtain wall development. In 1996, the regulations on the specialized specifications of curtain wall engineering and the provisional rules on strengthening the management of building curtain wall assignments have been successively released, which made the high quality of management curtain wall initiatives have a authorized foundation. According to their genuine predicament, numerous localities have also taken some corresponding feasible actions.
The emergence of the issue of light pollution does not mean that the glass curtain wall need to not be accomplished, but how to do it nicely. At present, the improvement of higher-tech has produced the content of curtain wall from single glass to metal plate, aluminum plate, alloy plate, marble plate, enamel sintered plate, and many others. By way of sensible design, the glass curtain wall and the curtain wall of steel, aluminum, alloy and other materials are merged. Jointly, it not only makes the large-rise buildings much more lovely, but also lowers the mild air pollution caused by the reflection of the curtain wall much more efficiently. It can further reduce the self-fat of the higher-rise structures and give full engage in to the advantages of the curtain wall constructing resources.
Glass performs a important position in the glass curtain wall. The glass variety of the glass curtain wall ought to be carefully chosen according to some parameters of the glass, and the glass with glare reduction efficiency should be selected. These parameters consist of the light and local climate parameters of the creating website, the transmission amount of visible light-weight, Reflection coefficient, transmission coefficient, reflection coefficient and absorption coefficient for sunlight, as well as heat transmission coefficient, thermal growth coefficient, and thickness, greatest size, fat, and wind resistance. It is nicely acknowledged that glass has transmission, absorption and reflection homes for gentle. The glass curtain wall uses distinct types of glass in accordance to these characteristics. The glass used for the glass curtain wall generally has clear glass, colored glass, warmth absorbing glass, coated glass, coated glass, laminated glass, and photochemical glass. The positive aspects and down sides of every single of them can be witnessed in the glass employed on these glass walls.
