1、辨别瓷砖质量的技巧——听声音
1. The skill to distinguish the quality of ceramic tiles -- listening to the sound1)墙砖或小尺寸瓷砖，一般用一只手五指分开，握住瓷砖，另一只手敲击瓷砖面，如果声音有金属质感，瓷砖质量更好。2)大地砖,电梯的一侧瓷砖在一方面,在另一方面在瓷砖的中间,如果一个沙哑的声音回应只要打击乐的声音青铜、陶瓷玻化砖的高度,耐磨性、抗弯强度高、吸水率低,不容易被污染,如果声音是多云,没有反应,玻化程度低(或裂缝),瓷砖的身体煅烧不足、耐磨性差、挠曲强度低,吸水率会更高，玻化砖容易被污染。
1) for wall tiles or small-size tiles, generally use one hand and five fingers to separate, hold the tiles, and tap the other hand on the tile surface. If the sound has metal texture, the quality of tiles is better. 2) large floor tiles, one side of the elevator tiles on the one hand, on the other hand, in the middle of the tiles, if a hoarse voice responds as long as the sound of percussion is bronze, the height of vitrified ceramic tiles, high wear resistance, bending strength, low water absorption, not easy to be polluted, if the voice is cloudy, no response, low degree of vitrification (or cracks), the body of the tiles is not calcined enough, poor wear resistance, strong bending Low degree, water absorption will be higher, vitrified brick is easy to be polluted.
2、瓷砖质量识别技能——测量尺寸，拼出尺寸一块瓷砖的标准尺寸有明确规定，如我们测量砖体后得到的结果与商品标志有差异时的数值不同，说明这种产品是劣质产品。逐个检查规格尺寸，尺寸误差大于0.5 mm，产品平整度大于0.1 mm，不仅会增加施工难度，同时装修后的效果也会大打折扣。同一规格型号的产品随意取出四块，进行拼装铺，通过这一步可以检查瓷砖尺寸大小、平整度、平直角等三个方面的问题。
2. Ceramic tile quality identification skill - measure the size. There are clear regulations on the standard size of a piece of ceramic tile. For example, if the result we get after measuring the brick body is different from the value when the commodity mark is different, it indicates that this kind of product is inferior. Check the specification and size one by one, the size error is greater than 0.5mm, and the product flatness is greater than 0.1mm, which will not only increase the construction difficulty, but also greatly reduce the effect after decoration. Four pieces of products of the same specification and model are taken out at will for assembly and paving. Through this step, we can check the size, flatness, square and other three aspects of tile.
3、瓷砖质量鉴定技巧——尝试吸水率
3. Ceramic tile quality appraisal skill: try to absorb water把瓷砖翻过来，在背面滴一些水。渗透越慢，质地越致密，内在品质越好。砖的质量与吸水速度越快、越脆和疏松吸水率越高。釉面砖背面正常吸水(当然质地较好砖吸收较慢，对比效果很明显);但假如商店卖吸水快的全身砖/玻化砖给你，再便宜也不用考虑，瓷砖胚不好，质量可想而知，长期使用很轻易出现裂纹等后果。
Turn over the tiles and drop some water on the back. The slower the penetration, the denser the texture and the better the internal quality. The faster the quality and water absorption rate of the brick, the more brittle it is and the higher the loose water absorption rate is. The back of glazed tile absorbs water normally (of course, the quality is better, the absorption is slower, the contrast effect is obvious); but if the shop sells the whole body brick / vitrified brick that absorbs water quickly to you, no matter how cheap it is, the embryo of tile is not good, the quality can be imagined, the long-term use is very easy to have cracks and other consequences.
