2: It is essential to understand the parameters
The hardness of the tile is the most important parameter and will directly affect the service life of the tile, which is especially important. The simplest method is to use the method of tapping and listening. The sound is crisp and clear to show that the inner quality is good and it is not easy to deform and break; the color difference and size are judged intuitively. Look at whether the colors of a batch of tiles are generally the same and can be compared. Well put together, small color, regular size is top grade.
Of course, the identification of technical performance can not only rely on feelings, but also must see the manufacturer's certification, in general, the technical standards of the products are all certificates issued by the state.
There is also an important parameter is the degree of wear, according to the low to high total is divided into five degrees, five degrees are super wear resistance, generally not for home decoration, home improvement brick can be selected from one degree to four degrees. The water absorption rate also determines the use of tiles. Tiles with high water absorption rate have low density and brick holes are sparse. They should not be used in places with frequent activities, so as to avoid cleaning after absorbing water and dirt. Tiles with low water absorption rate are highly dense and have very high water content. High moisture and dirt resistance.
3: Paving is particularly important before paving. Tiles often need to be soaked in fresh water for 20-30 minutes. Only after the water is filtered can the paving be done. Otherwise, it will be easy for the tiles to evaporate. Before use, check whether the color number and size marked on the outer packaging are the ones you ordered. Whether the bricks with the same color number have defects such as chromatic aberration or broken wire. Only use the same color number to make the color uniform. The cement label used for paving should be low-grade, cement thickness should not be too large, generally not more than 5mm. Acceptance should pay attention to the ceramic tile must be solid, no hollowing, no cracks, no skew, missing edges and other defects.
4: Tiles can not be purchased cheaper and some small manufacturers rely on lower production costs to fight crazy price war. Little did they know that the tiles would be used for many years. They saved time and bought tiles that were not worn by small factories. After one year, the brick surface was cracked, cracked, and unsightly. Spend money to re-paving bricks, once paved all kinds of electricity, gas pipeline can not be easily moved; secondly, the second decoration of the chaos and stir the whole family unrest. The most frightening thing is that some small manufacturers do not have environmental protection because they are able to reduce costs. Therefore, it is recommended that consumers choose tiles from regular manufacturers.
