Because the raw material is natural stone, floor tile products are usually radioactive. According to the national environmental protection standards, the radioactive level of decorative materials is divided into three categories: A, B and C, and the production, sale and use of Class A decorative materials are not restricted. It is best to choose grade A products for indoor floor tiles. When buying a floor tile, you can ask to see the environmental monitoring report of the floor tile to see which category the product belongs to. Polished tiles must have national compulsory product certification. Please pay attention to the report when choosing polished tiles. The radioactive detection and control of indoor decorative bricks are carried out, and the detection results are divided into three categories: A, B and C.
Only A-grade standard tiles can be used in residential interior decoration. Consumers should choose A-grade ceramic tiles when purchasing by themselves. Because it is difficult to see the difference between the three types of tiles in appearance, some informal decoration companies and small guerrillas will choose to use B and C tiles as the first-class tiles for interior decoration in order to save costs. It is best for the owner to ask a professional institution for radiation testing before moving in.
Dr. Dong Peng has been devoted to the research of negative ion ceramic tile technology to solve the problem of household air purification. We walked through the whole forest day and night. We tried 1000 kinds of materials and found the natural minerals that induce negative ions. Dong Peng air purification brick adopts natural mineral raw materials and national patent formula, which produces a large number of negative oxygen ions for a long time, forms a stable negative ion layer on the surface of the brick, stimulates water ionization in the air, and forms a large number of negative oxygen ions; Can continuously and comprehensively purify the indoor environment and form fresh air.
