There are many kinds of tiles, and how to choose correctly requires a certain knowledge base. Today, Xiaobian introduces you to the popular ceramic tile types in recent years - polished tiles.
Polished tiles have hard wear resistance, anti-freeze and anti-fouling, acid and alkali resistance, and have a long-lasting characteristics. The decorative effect can be compared with natural marble. The surface of the brick should be observed in a well-lit environment. There should be no color difference, no leakage or scratching. Traces, cracks, bumps, dirty colors, etc., bright color, strong mirror effect. Generally good has four characteristics: it looks bright, it sounds pleasing to the ear, and it is heavy and strong. There are no obvious defects on the surface of high-quality products, the color is bright and uniform, the brilliance is beautiful, and the size is regular.
When choosing a polished tile, pour it on the brick surface with a small amount of ink or water for about two minutes (the same method as I used to test marble), then rinse with water or wipe with a cloth to see if the residue is obvious. A little trace, the brick body has low water absorption rate, good anti-pollution property and good physical and chemical properties; if there are obvious or serious traces, the brick body has poor vitrification and poor quality.
Another method of selecting polished tiles can also tap the bricks by hand to carefully discern whether the sound is crisp and pleasing. If there is metal sound, the bricks have high density and good sintering. When the sound is rough and dull, the bricks are sintered to the bottom. The density is not high; if the sound is hoarse, the polished tile is inferior, and even the brick may have cracks. Generally, the hand rubbing brick is heavy, the density is high, the hardness is high, and the strength is good, otherwise the texture is poor.
