Good selection of tiles, the seven essential steps
A look: tiles is smooth
        First look at the tile surface is smooth, whether there are impurities, or whether something doped with different colors together. The second is to see whether it is surrounded by smooth, whether the phenomenon down side, if there are impurities or down side of the phenomenon, indicating that the raw materials in the production of ceramic tiles is not very good, and in the production process control is not particularly good, these ceramic tiles we try not to buy, and why? The latter will appear many problems Stones
Two knock: Listen to the crisp sound
¡¡¡¡The corner vertical tile floor, gently tap the surface of the tile, the tile surface if the sound is very crisp sound, it means that the degree of firing ceramic tiles, vitrified degree are very good quality, water absorption better, if this tile hoarse voice comparison, it means that the tile during the firing process, the firing time is too long or too short, bad vitrified degree, problems may arise in the process of use or Stones.
Three water: water absorption test
        Some drops of water gently on the back of the tile to see if it drops degree spread. If the water drops substantially no diffusion, it shows the good level vitrified tiles, low water absorption, it is relatively abrasion resistance, stain degree will be relatively better. If the water drops quickly spread, it shows the back of the high water absorption tiles, the tiles are likely to relatively loose, its durability as well as density, relatively speaking, is relatively poor.
Four mill: durability test
        Analyzing brick fourth step is to measure the quality of its durability. With sharp objects, such as keys, as well as knives and so on, straining in the brick surface scratching, if in the process of planning the brick face obvious scratches, it shows the durability of the brick is not high, if Push plan when, brick surface or smooth as new, it means that the wear-resistant tiles is very good, in the future use of which will not scratch other issues.
Five Videos£ºAntifouling performance test
        Measure this brick antifouling properties, there is a very simple way to find an oil-based ink pen or something and so on, straining to scratch the surface of the brick, leaving traces, had left their mark after five to ten minutes we use relatively clean toilet paper, cloth to gently wipe, if the brick surface stains left some traces, it means that the brick stain resistance is not high, if once cleaned, it means that the anti the relatively high level of pollution in daily use among the antifouling property is relatively good.
Six volume: whether the size of regular
        With a vernier caliper to measure the brick corners, and diagonal. We can clearly see the four corners of the measurement data is the same, for example, are 80 cm if the error is more than 0.5 mm, then it shows the diagonal corners of the brick is not particularly standard, this will cause in the future shop which posted a gap or misalignment phenomenon. If the difference is within 0.5 mm of the four corners, we can determine the brick does not appear such a situation said above in the process of paving.
Seven Contrast: brick flatness
¡¡¡¡General flatness bricks are used calipers to measure, but in everyday life we can together two bricks and place them stand up to see two bricks there is no gap, if there is a significant gap, it shows this brick flatness is not very good, in the daily paving which we will encounter this phenomenon skirting and arched, two bricks if there is no obvious gap, it shows the flatness of the tiles is very good.
