Experts suggest that "ultra-white" tiles may have a high water absorption rate, which can lead to poor adhesion during installation. When it comes to wall tiles, lower water absorption is generally better. This is because tiles with higher absorption tend to soak up more moisture, which can cause them to shrink and crack over time, leading to peeling or damage. However, for wall tiles specifically, a certain level of water absorption is still necessary to ensure proper bonding when using cement mortar. A low water absorption rate might make the tile too dense, reducing the effectiveness of the adhesive and increasing the risk of voids. If you're using only cement mortar, it's recommended to choose wall tiles with a moderate water absorption rate—around 10% is often ideal. Also, be sure to soak the tiles sufficiently before laying them. If you opt for low-absorption tiles, consider using a safe and eco-friendly tile adhesive for better results. The finer the particle size in the tile, the stronger it tends to be. Tile strength is closely related to its density, which affects both pressure resistance and fracture resistance. When selecting ceramic tiles, especially for high-traffic areas like living rooms, you can check the back of the tile. The finer the particles, the denser and stronger the tile is likely to be. Glazed tiles can sometimes develop glaze defects. One common issue is "glaze cracking," where the surface becomes uneven or develops small cracks. This usually happens due to inconsistencies in the glazing process or during the firing stage in the kiln. To avoid such problems, it's best to purchase from reputable brands known for quality control and reliable manufacturing processes. When buying ultra-white tiles, be cautious about excessive zirconium silicate content. Some tiles fail quality tests due to an overuse of this material, which can increase radiation levels. According to Yan Bin, Secretary General of the China Building Sanitary Ceramics Association, ceramic products do have some level of natural radiation, but it’s typically negligible after proper processing. In countries like Germany, strict environmental standards ensure that ceramic products are safe for use. As long as you choose Class A certified tiles, even for large areas, there's no need to worry about radiation risks. In the production of polished tiles, zirconium silicate is sometimes added to enhance the white color. However, some manufacturers may add excessive amounts to achieve an "ultra-white" appearance, which could lead to higher radiation levels. Always check the quality report and choose tiles from trusted suppliers to ensure safety and durability.
