How to choose a good tile to avoid unqualified products
>>> Links: Experts teach you how to carefully calculate and buy tiles Experts say that the city: "ultra-white" may be excessive radiation, low water absorption may not be paved According to data released by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on the 20th of last month, among the 364 kinds of ceramic tile products that were subject to supervision and spot checks, 97 products were unqualified and the rate of failure was more than a quarter. Among them, the problem of unqualified products is mainly focused on the failure quality, water absorption rate, size, and radioactivity. In addition to the quality of the problems detected in addition to urging businesses to put a good production quality, what tips for consumers? ◠Wall tiles are not as good as water absorption Many people think that the lower the water absorption rate of ceramic tiles, the better, because ceramic tiles with higher water absorption are more likely to absorb water, and after thermal expansion and contraction, they will cause cracks on the surface of ceramic tiles and peeling of the entire tile. However, Liu Zhiyan of Dongpeng Ceramics stated that the lower the water absorption rate, the better. Relatively speaking, for a wall tile, it still needs a certain water absorption rate to ensure that the wall tile hollowing rate is reduced when laying cement mortar. , firm shop. Liu Zhiyan said that if you do not use any tile adhesives, only cement mortar, it is recommended to select the water absorption within a certain range of wall tiles, such as about 10%, while paving, we must ensure that the wall tile immersion time is sufficient, 2-4 Hours are appropriate. If you choose some tiles with lower water absorption, it is recommended to add safe and environmentally friendly tile adhesives when laying. ◠The finer the ceramic tile particles, the stronger the strength The strength of a tile is related to its compressive and flexural properties, and its strength depends on its density. In this regard, Liu Zhiyan said that when consumers select tiles, especially for the selection of the living room and other public space tiles, you can identify the level of tile strength by viewing the fineness of the tile on the back of the tile, in general, the more delicate tile particles The higher the density, the higher the breaking strength. >>> Links: How to calculate the usage of tiles ◠Glazed tiles may produce violent glaze Many people will encounter tile cracking problems, Liu Zhiyan said that the cracking of a tile is caused by wall deformation and cracking. When the paving cement code is too high, it can easily cause cracking of tiles. As for the ceramic tile itself, there is also a phenomenon of cracking, which is the “violent glaze†that exists in the glazed tile. The reason is that the glaze is uneven in thickness during production, resulting in partial glaze cracking when burned in the kiln. It is recommended that consumers More choices for trusted brands buy tiles. ◠Buy ultra-bright bricks alert zirconium silicate overdose The ceramic tile radiation in the quality inspection report was not up to standard. According to Yu Bin, Secretary General of the China Building Sanitary Ceramics Association, tiles and other ceramic products have radiation. For countries with high environmental standards such as Germany, there is no similar conclusion. Thus, tiles, etc. The environmental performance of ceramic products is indisputable and consumers can use it with confidence. In addition, for materials such as ceramic tiles and other ceramic products, Sui Bin said that radioactive materials will continue to decay, these raw materials after natural purification and artificial processing, its radioactivity is negligible. As long as consumers purchase quality Class A tiles, even if they use a larger area, do not worry about their radiation problems. The unqualified products that were detected this time were also mainly due to the addition of zirconium silicate as the test substance. It is understood that in the production process of polished tiles, in order to achieve the effect of whitening, zirconium silicate is added in an appropriate amount, and some companies add excessive amounts of ultra-white tiles to produce ultra-standard tiles. Tiles to buy cement space R 180 degree linear lights is a product suitable for offices, kitchens, living rooms, corridors and other places. The difference between it and the P Panel Linear Lights is the light-emitting angle. It has a light-emitting area of 180°, and the range of light it emits is larger.
