How to judge the quality of tiles?
By judging in the strong light: high finish products, pure color, easy to stick dirty dirt, easy to clean, self-cleaning good. Judgment can be selected in the strong light, from the side carefully observe the product surface of the reflective, the surface is not a small trachoma and pitting, or trachoma and pits little as well. High brightness indicators of the product using a high quality glazed material and a very good glaze process, the light of the reflective good, uniform, so that the visual effect is good, it seems high grade products.
Through the touch feel and knock porcelain listening judgment: the choice can be hand gently touch the surface, feeling very smooth and delicate as well. You can also touch the back, feeling "sand sand" fine friction feeling as well. The same specifications of products, good quality, high density of brick feel are more Shen, on the contrary, the quality of the product feel lighter.
In addition, you can hit the ceramic surface by hand, generally good ceramic material was knocked out the sound is relatively crisp. And if the sound of vigorous and echo long as percussion bronze bell sound, the porcelainization of a high degree of wear resistance, high flexural strength, low water absorption, not susceptible to pollution; if the sound mute, the porcelain degree is low ( Even the existence of cracks), poor wear resistance, low flexural strength, high water absorption, highly susceptible to pollution.
1. the same size the same thickness, the heavier good. 2. A few drops of water on the back, good water absorption. 3. Choose your own color.
First, look at the surface tile color
Market tiles of various types, color is also a wide variety, according to the tiles of the variety and technology, tiles can be divided into anti-skid brick, polished tiles, tiles, glazed tiles, micro-brick and other types. If the quality of tiles according to the grading also has a variety of grades, mainly divided into excellent products, qualified products, and other goods.
To check the quality of tiles and their own post-paste only need to be carefully observed through the problem can be found, the quality of their own tiles is relatively poor need to replace the tiles are mainly reflected in the tiles surface cracks uneven, corners are not Floor tiles, although the surface looks bright, but the glaze layer surface color problems or glaze layer or glaze layer of inclusions spots. The quality of the tiles after paving the main inspection of the overall surface of the flatness in the range of two meters is not greater than two millimeters, between the brick and brick joints are not greater than 0.5mm, seam flatness in the length of 5m No more than 3mm, if more than the above data within the range are unqualified.
Second, the percussion test tiles installed with or without hollowing
In the room, around the room with a small iron bar and other special inspection of the wall hollowing the tool, gently tapping the four corners of the tiles and the middle of the sound crisp no hollowing, if detected the problem of hollowing, should be marked out, Timely eradication with floor tiles.
Third, in the tiles on the splashing water detection
In the kitchen, the bathroom has a drainage slope requirements of the floor tiles paved tiles, in check their water is smooth, in the slope above a lot of water can be detected. After pouring water in the above, waiting for a moment, see where there is water to show that the floor tiles paved uneven, or to the water slope is not enough.
Listen to the sound, look bright, Britain weight, flexibility (put the tile, and then let go)
