s The so-called glazed tiles are fired with a layer of glazed surface on the surface of the tiles, but because the firing materials are different, they are divided into clay firing and porcelain clay firing. Generally speaking, this smooth glazed brick is easy to clean and maintain, and it is used more frequently on the walls of general kitchens and bathrooms. 1. Which brick is better? Is the lower the water absorption, the better the quality? Many netizens told me that they chose tiles based on the water absorption rate, because everyone said that the lower the water absorption rate, the better the quality. Is it really Jiangzi? Doubtful, Lao Xie said that strictly speaking, this statement is correct but not comprehensive enough. Because depending on the location of the tiles, the requirements for the water absorption of the tiles are different. Like floor tiles, the national standard water absorption rate is E≤0.5%. The larger the value, the smaller the density, and the easier it is to penetrate. If it is a wall tile, then the water absorption rate between 10%≤E≤16% is considered to meet the national standard. Because wall tiles need to be laid vertically, a certain degree of adhesion must be required. If the water absorption rate is too low, the pasting is unstable, and the wall tiles are prone to cracking and peeling in the later stage. 2. The price of ceramic tile
s differs so much, what is the difference? Good or bad are the same, but the cheap ones are not the same and usable! Lao Xie said that now the ceramic tile store will make various model rooms, and the effect will look the same after the paving! (Of course I mean tiles with similar prices. If you have to compare ordinary tiles with big brands like M, fools know the expensive ones!) So Lao Xie taught simple tricks to distinguish good tiles from bad ones. . One touch, two knock, three look to easily identify good and bad tiles. Lao Xie said, because the back of the hand is a more sensitive part of the body, it is more intuitive to feel the surface of the tile with the back of the hand. The better the quality of the tile, the better the surface finish, not rough at all, and feels as slippery as an egg~ But if you are to identify the following type of climbing wall tiles, you will not use the back of your hand, but use your little finger to feel the middle The gap, the better the quality, the smoother the hand feel, without any sense of blocking. (Of course, this is for floor tiles that imitate small square tiles. This method is not suitable for old tiles.) Whole-body bricks. Whole-body bricks are actually porcelain tiles that do not need to be glazed. We often say that it is non-slip. Wear-resistant bricks refer to whole-body bricks. Polished tiles and vitrified tiles are all types of bricks. The impact resistance of vitrified tiles is quite good, and there is no need to worry about a pit when a hard object falls and cuts. The disadvantage is that the pattern is too limited. Mosaic oh, I forgot to mention the mosaic, this kind of brick is quite small, hard, wear-resistant, acid-resistant, and not easy to break. And because of its rich colors, it creates a strong sense of hierarchy. Generally used in small kitchens and bathrooms. The purchase aspect is much simpler than the previous two bricks, which is simply to look at the style and the flatness of the cutting surface. After touching the surface, knock again, not directly with a hard object, but knock on the knuckles. If the sound you hear is quite crisp and the echo is particularly loud, this is definitely a good brick. If you hear a muffled sound, it means that the low-density tiles have a poor firing effect and are prone to back seepage, which is a poor-quality tile. One step is to see, this step is not common to all bricks, mainly for bright bricks. Looking at the reflective mirroring of the surface, the higher the finish, the clearer the lines on the surface of the tile, the clearer the mirroring, and the less likely to be deformed. (If it is an imitation version, the image of the shadow on the tile will be blurred, and the lines will be distorted. Because the imitation version is just a starting version and cannot be re-engraved.) Looking at the tile body, which is the side of the tile, the more the color of the body is Turbidity, the worse the quality, indicating that there is a lot of muck in the middle. A good brick body is fired from natural ore, and the color is close to white. Look at whether there are black spots in the middle. The more black spots, it means that the firing time or temperature is not enough, and it is caused by insufficient oxidation. This kind of brick is equivalent to sandwiching raw rice, which is unripe. Once on the wall, it is easy to crack and fall off. Look at the back of the ceramic tile. When choosing a ceramic tile, you should pay special attention to whether the pattern on the back is consistent. This will directly affect the post-assembly. It is recommended to choose the original batch of production. Or buy it in a store. 3. How to do the water test? Can you judge the permeability of the tiles? Everyone knows that ceramic tiles have a certain water absorption rate, so to judge its permeability, the first thing that comes to mind is the water test. But in fact, this experiment is not completely scientific. If the wax water drops on the back of the tile, it will still not penetrate. So what we observed in this experiment is not that the back of the tile does not absorb water, but that there is no watermark on the front of the tile. 4. How to choose the floor tiles? Any recommendations? For the working-class people who don't have time to clean, the soaked tiles are a good choice. They are cheap and easy to clean. This kind of whole body brick with non-layered embryo body is the cheap one among the vitrified bricks and belongs to the obsolete brick. ) Now I buy this kind of bricks for old age or rental house decoration. I usually don't choose this kind of brick for my own home. For those who have requirements for quality life, if you choose vitrified tiles, it is recommended to choose full polished glaze, microcrystalline stone, and imitation jade texture, which has more room for pattern selection. (Although these patterns are hard to see where they can be cut, at least the price is relatively high.) The picture below is the current trend of full-body bricks. A layer of crystal wear-resistant layer is added to the surface of the whole brick, which has stronger hardness and anti-permeability. Anti-scratch performance is better.
