Micro pores will be produced during the production and polishing process of ceramic tiles. Super clean and bright technology means that these tiny pores are filled with nanotechnology on the surface of the tiles, so the anti-fouling performance is very good. It is not super clean. The anti-fouling performance of bright ceramic tiles is not as good as that of super clean and bright ones. The so-called polycrystalline powder refers to the raw material of the bricks. A kind of polycrystalline particles are added to the raw materials to make the bricks look more three-dimensional and more durable than ordinary seepage tiles. nice. It is recommended to buy branded ceramic tiles, because I work in the marketing engineering department of Nanchang Xinzhongyuan Ceramics and sell ceramic tiles. I know a little bit about the inside story of the ceramic tile industry. I hope you will be careful when choosing.
