Absolutely not. Especially the negative ion ceramic tile has an additional negative ion functional layer than the ordinary ceramic tile. The functional layer adopts patented formula, adding natural rare minerals (tourmaline) and other raw materials. Natural mineral raw material (tourmaline) forms electromagnetic field, which can excite ions in the air, thus producing a large number of air negative ions. Air negative ions can neutralize and adsorb positively charged air pollutants, airborne dust and other harmful substances, become uncharged or settle after macromolecules, thus purifying the air.
Will not produce other harmful substances. Negative ions, like ordinary tiles, have no radiation and meet the national standards for building ceramics, otherwise the industrial and commercial bureau would have sealed them up.
According to the research on the effect of negative ion technology on improving the environment of subway station published by Warm Air Conditioning magazine in March 2009, it is concluded that negative ions can continuously and effectively reduce dust, eliminate VOC, remove odor, degrade formaldehyde and toluene, and sterilize. Conducive to improving air quality and human health, without secondary pollution.
