Tile is one of the important materials for decoration, which may be used in a large amount. Tiles can be applied to walls and floors. Many people only know that the board will have formaldehyde harmful substances, so it is easy to ignore the radiation problem of tiles. If you buy unqualified tiles, you will also hurt your body. What is the radiation standard for tiles? What are the radiation protection methods for tiles? Get to know from Hanse!

Tile Radiation

Tile radiation refers to the phenomenon that tiles contain radioactive substances, of which the radioactivity of glazed tiles is more obvious. Glazed tile is a layer of glaze applied on the base of tile. The surface of tile is colorful with rich patterns and patterns. Most of the raw materials for glazed tiles come from potassium containing minerals, such as feldspar and mica, which contain certain radioactive substances such as uranium and radon. It is still radioactive after physical and chemical processes such as crushing and sintering. And in order to make the surface of tiles bright and clean, zircon sand with high radioactivity is often added to the raw materials, which also makes some tiles with high radioactivity.

What Is The Radiation Standard For Tiles

Tile has radiance, this does not mean that you can not lay tile in the bedroom. The radiation level of many tiles meets the national standards. According to the national standards, the radiation of tiles can be divided into three types: A, B and C. the radiation level of class A is low and the scope of use is not limited. To judge whether the tile is a radioactive product is not to measure whether it is simply qualified or unqualified, but is divided into three categories: A, B and C.

- The radioactivity level of Grade A tile is low, and its production, marketing and application scope are not limited.

- Grade B tiles can not be used for the interior decoration of class I civil buildings such as residences, hospitals, etc., but can be used for the exterior decoration of class I civil buildings and the interior and exterior decoration of all other buildings.

- Grade C tiles can only be used for external finishes of buildings and other outdoor purposes.

Generally speaking, the radioactive pollution of dark porcelain (92to.com) bricks is relatively serious. The darker the color of the tiles, the more radioactive substances they contain, the greater the radiation. The whiter the tiles, the more additives they contain, and the greater the radiation intensity. The zirconia brightener used in ultra white tiles has high radiation.

What Are The Radiation Protection Methods For Tiles

As radiation is invisible, it is not easy for people to detect it in the process of use. Therefore, it is not suitable to use large-area paving during decoration. It is better to choose matte bricks for laying tiles. At ordinary times, the lights should be turned on as little as possible at home to avoid light reflection.
