Due to the different brands, crafts and materials, there are also great differences in price of ceramic tile products. Consumers should not blindly believe in high-priced goods when purchasing ceramic tiles, nor should they be ignorant of their greediness and cheapness. The true purchase method can be selected from inexpensive and inexpensive products.
Marco Polo Tiles Strong Tiles
1. Look at the density, hardness and quality of the tiles.
It can be beaten, and the sound is crisp and the porcelain density and hardness are high and the quality is good. Lightly tap the floor tile with your hand. If the brick emits a "beep, bang" sound, it indicates that it has insufficient sintering and the texture is relatively small. If a slight "beep" sounds, its texture is relatively hard compared to the previous one.
2. Look at the water absorption rate of the tiles.
The lower the water absorption rate, the higher the inherent stability of the tile, and the more suitable it is for the space with high moisture or moisture content, and no problem such as dark spots. The water droplets are on the back of the tile, and the water is diffused and the temperature of the tile is slow.
3. Look at the color of the tiles.
You can scrape the tile glaze with a hard object, and if it leaves traces, it means poor quality. Look at the color of the tiles is not clear, look at the naked eye with pinholes, pinholes are easy to accumulate dirt.
4, look at the flatness of the tile.
The sides are straight, easy to lay and the effect is good. Take out any four tiles from the box and compare them on a flat floor. Whether the four bricks are flat and consistent, whether the tiles are diagonally embedded.
Then tap the surface of the tile with the palm of your hand and listen to the sound: the sound of the good tile is relatively low: the sound of the tile is not bright, and there is a clear echo. Of course, it is relative to judge the good or bad from the sound. However, the first comparison method can not be underestimated. The biggest difference between domestic and imported bricks is mainly in the specification consistency of ceramic products.
5, look at the glaze of the brick.
The surface of the tile should be smooth and delicate; the high-gloss glazed tiles should be crystal-clear, and the matt and semi-matt glaze should be soft and reflective. You can try to scratch the surface of the tile with a hard object. If there is a scratch, it means that the glaze is insufficient. After the glaze on the surface is polished, the brick surface is easily stained and difficult to clean. Second, look at the product size is standard, you can use the caliper to measure the diagonal, irregular tiles will not be straight in the paving, resulting in unsightly. Third, look at the deformation, you can directly observe with the naked eye, look at the side of the product straight, so that the product is small deformation, construction is convenient, the tile surface is smooth and beautiful after paving. Four look at the pattern, the flower pattern should be delicate and realistic, without obvious defects such as lack of color, broken line, and misalignment.
6, look at the packaging.
First of all, look at the name of the factory, the site and the trademark, so as not to buy the "three no" products. Second, look at the product quality level and the water absorption rate. In general, the lower the water absorption rate, the higher the strength and the better the frost resistance. If the user purchases ceramic tiles mainly for paving or for outdoor walls, it is necessary to purchase products with lower water absorption, such as porcelain tiles or enamel tiles.
If the user purchases bricks mainly for indoor walls, such as kitchen and bathroom walls, products with higher water absorption, such as ceramic tiles, may be used. However, it should be pointed out that such products have relatively high requirements for crack resistance, thermal shock resistance, pollution resistance and chemical resistance. Third, look at the friction properties of the product. If you buy ceramic tiles for paving, you need to check the coefficient of friction and wear level of the product.
7, look at the surface quality.
First of all, look at the color of the suit is beautiful and pleasing, in line with your own aesthetic taste. Secondly, about 1 meter away from the sample, under certain lighting conditions, observe whether the sample has surface defects such as glaze, crack, smoke, greasy, glaze, spots, bumps, etc.; about 3 meters from the sample, observe the surface of the product. The difference in color is to give a rough grasp of the gloss of the product. Third, gently tap the sample with your hand or hammer. If there is a metal echo, the product structure is good; if there is a muffle, it indicates that the product may have structural delamination defects.
