Tile selection for color selection should pay attention to the color is too bright, the greater the radiation

When we choose ceramic tiles, we often see that the color of the tile surface is brighter and more beautiful. I don’t know that for tiles, the more the color, the more radiation. Below, let's take a closer look at the issues to be aware of when choosing a tile.

According to the survey, most homes and office buildings prefer to use brighter tiles for decoration, because the bright tiles not only make the room look rich and bright, but also can make up for the lack of lighting to some extent. Generally, the light reflection coefficient of the white powder wall is 69%-80%, and the mirror glass is 82%-88%. The walls and floors of the living room are decorated with certain tiles (mainly polished tiles and some antique bricks). The light reflection coefficient is as high as 90%, which greatly exceeds the physiological adaptation range that the human body can withstand, which will cause light pollution and damage people's health.

Light pollution in the environment can be roughly divided into three types:

First, outdoor environmental pollution, such as the reflective exterior wall of a building;

Second, indoor environmental pollution, light pollution caused by indoor tiles belongs to this category;

The third is local environmental pollution, such as book paper.

Among them, polished bricks and antique bricks use related technology to increase the brightness of the brick surface, resulting in a higher reflection coefficient of light, even 10 times higher than the reflection coefficient of the matte decoration. Light pollution can cause the director of the Department of Ophthalmology, General Hospital of Myopia and Cataract, said: Light pollution can cause the retina of the human eye to be stimulated.

In general, after watching TV for several hours in a row, people's vision will temporarily drop by 30%. In the long-term living environment with smooth walls and floors, light reflection will stimulate the retina, beyond the coordination of the eyes, causing eye fatigue and even leading to reduced visual function. Light pollution can also cause damage to the cornea and iris of the human eye, inhibiting the function of photoreceptor cells of the retina.

The study found that people who work and live in a bright white polluted environment for a long time, their vision will drop sharply, and the incidence of cataracts will be as high as 45%. At the same time, it is easy to cause dizziness, upset, insomnia, loss of appetite, depression, and body. Weakness and other symptoms similar to neurasthenia. The survey shows that long-term exposure to various light pollution in the surrounding environment is also one of the main reasons for the high myopia rate among young people in China. Choosing tiles to make your eyes comfortable. Secretary-General Bin said that since August 1, 2005, the state has implemented mandatory signs (3C marks) for three types of decoration and decoration products, including porcelain tiles, mainly to detect whether their radioactivity is Meet the standard. Because some ultra-white tiles use a "white" additive in the production process, and this additive contains radioactive substances, it may form radioactive pollution and light pollution. In the regulations, the certified porcelain bricks are products that implement the GB-T400.1 standard and have a water absorption rate of less than or equal to 0.5. The polished tiles and antique bricks are mainly used, and the glazed tiles and some wall tiles are not included in this range.

The best visual environment should be that it is fully coordinated with the human eye in terms of color, light frequency, brightness, shape of the object, and movement. Therefore, when decorating the home, it is best to choose matt bricks; the study room and children's room should try to replace the floor tiles with the floor. If polished tiles are used, usually try to open small lights at home, and avoid direct light or reflections on the eyes. Due to the strong reflection of white and metallic tiles, it is not suitable for large areas in the living room.
