Polishing ceramic tile is a new type of decorative ceramic material which is very popular at home and abroad in recent years. It has the characteristics of hard wear-resisting, anti-freezing and anti-fouling, acid and alkali resistance, and the decorative effect can be comparable to that of natural marble. When selecting the polished tile, the surface of the tile should be observed in a well-lit environment, there should be no chromatic aberration, leakage, scratches, cracks, missing, dirty, etc., bright color, strong mirror effect.

In general, good polished tiles have characteristics: they look bright and bright; they sound sweet, they are heavy and solid, they have no obvious defects, they are bright and uniform, and they are regular in size. What should we pay attention to when selecting polished tiles?

1. Pollution resistance of polished tiles
Pick a small amount of ink or water in the polished tile and let it rest on the brick for about two minutes. Then rinse with water or wipe with a cloth to see if the traces of residue are obvious. If there are only a few traces, the brick body has low water absorption and anti-pollution. Well, physical and chemical properties are good; if there are obvious or serious traces, the vitrification of the brick body is poor and the quality is poor.

2. The density of polished tiles Another method of selecting polished tiles is to tap the brick body by hand to carefully discern whether the sound is crisp and pleasing. With metallic sound quality, the brick body has high density and good sintering; the sound is rough and dull, then the brick body At the end of the sintering process, the density is not high; if the sound is hoarse, this type of polished tile is a bad product, and even bricks may have cracks. Hand rubbing bricks, under normal circumstances, feel heavy, high density, high hardness, good strength, and vice versa, texture is poor.
