Buy a tile "best" may not choose to avoid substandard products more.

<p> City experts said: "super white" may be too low water absorption of radiation is not strong may Stones </ p> <p> China's General Administration of Quality Supervision, Inspection and Quarantine recently published data show that ., in the 364 kinds of ceramic. brick products for the supervision and inspection, there are 97 kinds of product failure, failure rate of more than a quarter.. Among them, the problem of substandard products exist mainly in failure strength, water absorption, .size, etc., the failure on the radioactive.. Apart from the problems of quality control urged the businessmen to the good production quality, the role of the consumer and which prompted it?. </ P> <p align = " .; center "> </ p> <p>, óè wall is not water absorption as low as possible </ p> <p> a lot of people think that the lower the better water absorption of ceramic tiles, .as. higher water absorption of tiles more easily absorb water, by thermal expansion or contraction will cause the tile surface after the crack and the entire tile falling off.. However, Winter said Peng Liu Zhiyan ceramics, water absorption, the lower the better is .a relative term, and for the wall, it is necessary to ensure a certain degree of water absorption of cement mortar with the hollowing Stones reduced rate of wall., paving firm.. Liu Zhiyan, if without any tile adhesive, cement mortar used only .if recommended to choose a range of water absorption in the wall, such as about 10%, while paving the wall when the soak time must ensure that adequate ,2-4. hours is appropriate.. And if you choose a lower number of water .absorption of tiles, paving, proposed to add safety and environmental protection of the tile adhesive.. </ P> <P> <P> <p>, óè more delicate ceramic particles higher strength </ p> < .; p> tiles related to its pressure strength and fracture resistance, and strength in turn depends on its. density.. In this regard, Liu Zhiyan said that consumers in the selection of tiles, especially the choice of living room tiles in terms of public .space, you can view the tiles on the back of fine particles in the degree to identify the level of tile intensity, under normal circumstances, the more delicate ceramic particles., the higher the density, the higher the breaking strength.. </ .P> <p>, óè glazed storm glazed possible </ p> <p> tile cracking a lot of people will encounter problems, Liu Zhiyan that there is a tile cracking is caused by the deformation and cracking of the wall, .the shop. when the label affixed to the cement tiles are likely to cause excessive cracking.. As for the tile itself, there is a cracking phenomenon, there is a tile of "violence glaze", which is the cause of the uneven production .Bohou glazing, firing in the kiln when the glaze layer burst produced some of the proposed. consumers more choice of trusted brands to buy tiles.. </ P> <p>, óè buy super white zirconium silicate brick guard over < ./ p> <p> tiles in the inspection report of radiation is not up to the Secretary-General of China Building Sanitary Ceramics Association, said Miao Bin, tiles and other ceramic products are. radiation, such as Germany, for countries with high .environmental standards is not the same argument, we can see, tiles and other ceramic products, environmental performance is unquestioned, consumers can rest assured that use.. In addition, tiles and other ceramic products, raw materials, said Miao Bin, will continue to .decay of radioactive materials, these raw materials after the purification of natural and man-made process, its radioactivity is negligible.. As long as the quality of qualified consumers to buy A class of ceramic tile, even if the use of the area and then .great, do not have to worry about the radiation.. </ P> <p> and the detection of substandard products occurred mainly due to the detection of zirconium silicate added to the variety of chemical substances.. It is understood that polishing .in the production process, in order to achieve the whitening effect, will amount to add zirconium silicate, and some enterprises for the production of ultra-white brick and overused, leading to excessive radiation the main tile.. </ P>..
