Recently, the Municipal Administration for Industry and Commerce of Shanghai Administration for Industry and Commerce conducted quality inspections on 21 batches of ceramic tiles sold in 6 districts such as Fengxian and Qingpu. After testing, one batch was unqualified, and the failure rate was 4.76%. The main unqualified item is the strength of the damage. The Shanghai Administration for Industry and Commerce issued a consumer reminder. When purchasing ceramic tiles, one should pay attention to the water absorption rate. Wall tiles can choose tiles with higher water absorption, while the ground should choose low water absorption, because the loose brick holes can easily absorb water and dirt, it is not easy to clean and easy to deform. Second, pay attention to the hardness. High-quality ceramic tiles generally have high hardness, strong toughness, and are not easily broken. It is not easy to crack and deform after a long time after paving. The intrinsic quality of the tiles can be checked by tapping the pieces at the time of purchase. Take two tiles and tap gently. If the sound of the brick is crisp and with some metal sound, it means that the inner quality is better and the hardness is higher. If the sound is hoarse, the brick may have cracks and the hardness is not high. Finally, pay attention to the wear resistance. The wear resistance is generally divided into five degrees. 1, the degree is generally used in places with few walls and activities; 2, can be used in bathrooms and bedrooms where there is no hard friction; 3, the degree can be used in places with large people, such as the living room and kitchen; 4, high degree of wear resistance, luxury decoration, in the residential foyer and corridors and public places is very suitable; 5, the degree is generally used in airports, stations and other public places with great traffic.
