Tiles to buy six notes

A few days ago, a city environmental protection association detected a home environment ceramic ware radiation exceeded the standard, "national pumping" out of the ceramic tile radionuclide failed quality events so many consumers exclaimed "injury can't afford!" Stepped in the foot of the tiles are also radiation? Is it harmful to human health? Is it inappropriate for children's rooms to be tiled? In the past few days, the reporter visited the market of Tao Wei in Chancheng, and interviewed professionals to find out if the tiles had any radiation.

Consumer reminder:

1, to the regular mall to buy tiles consumers should go to the formal building materials market, brand companies to buy tiles. Lin suggested that when buying tiles, they should ask the merchants to present their product specifications and check whether the radioactivity standards of the tiles have reached class A and do not buy low-priced products.

2. Look at the tiles that are used for interior paving on the certificate and indicate on the outer package: "Radiation Level: A". Ma engineers reminded that if the product packaging has a green environmental protection mark, ISO14001 international environmental protection system certification, quality system certification mark, national inspection mark, etc. better. In addition, polished tiles must have a national mandatory product certification (3C for short).

3. It is not recommended to lay natural stone on a large scale. In general, natural stone is higher in radionuclides than tiles and is not recommended for large areas. It can be used in small areas for decoration.

4. It is not recommended that the precipitation rate of the radioactive element on the surface of the color glaze bricks of large-area white and dark products be higher than that of ordinary bricks. Lin Chifeng suggested that dark tiles should not be laid on a large area in the home environment. Since these products contain more long-lived natural radioactive isotopes such as xenon, thallium, radium, and potassium, the amount of radiation is relatively large.

5, it is recommended to use matte products, especially children's room, the best choice for matte tiles. If paving polished tiles, avoid direct light on the brick surface, usually at home as small as possible, otherwise it is easy to bring light pollution due to light reflection. In addition, windows should be opened more often to allow air circulation.

6, commissioned by the agency with CMA certification testing If consumers choose to commission the relevant agencies to test the product's radiation dose rate, should be selected CMA certified indoor environmental testing unit testing.

Finally, Lin also explained to the reporter: Some ultra-white polished tiles or sanitary ware products have added zirconium oxide or zirconium silicate. The zirconium silicate has a higher radioactivity, but the general glaze of sanitary ware is about 0.7mm to 0.8mm. The content of zirconium silicate is also very low.
