Don't let "certification publicity" mislead

don't let "certification publicity" mislead

at present, some businesses almost put the quality certificate in the most eye-catching position in the store. When you look carefully, you find that there are a variety of certification Institutions, such as "China Light Industry Certification Center", "China XX Mark Certification Committee", "Consumer Protection Foundation", etc. However, people from the national sanitary ceramics professional committee pointed out that consumers should polish their eyes when purchasing sanitary products to avoid being misled

the thickness of glaze layer does not mean sterility

some businesses boast that all their sanitary wares use imported glaze, and the layers of glaze are thicker than domestic products, so the glaze of sanitary wares is smooth and easy to wash, and the thickness of glaze layer can ensure sterility, and long-term use can ensure health. In fact, it doesn't matter how many layers of glaze, as long as the surface finish of the product meets the national standard

high temperature does not mean good quality

in many bathroom specialty stores, some sanitary wares that look the same on the surface can be priced hundreds of yuan less. Some shopkeepers explained that all he sold were high-temperature ceramics, which were absolutely high-temperature and sterile, and the price was naturally higher. The cheap one is low-temperature pottery, and the quality is not guaranteed. In fact, high-temperature ceramics and low-temperature ceramics are purely commercial speculation, which has nothing to do with the quality of sanitary ware. These high and low temperatures are only the firing temperature. When the firing temperature is below 1300 ℃, it is more conducive to energy saving. Low temperature does not mean poor quality, as long as the finished products meet national standards

precautions for bathroom purchase:

first, consumers can choose to carefully observe the reflection on the surface of bathroom products from the side under strong light, and it is better to have no or little sand holes and pockmarks on the surface. Products with high brightness index adopt high-quality glaze materials and very good glazing technology, which have good light reflection and good visual effect

second touch: you can rub gently on the surface with your hands, and it is better to feel very flat and delicate. You can also touch the back, and it's better to feel the slight friction of "rustle"

three ears: you can tap the ceramic surface by hand. Generally, good ceramic materials make a crisp sound when being knocked

four ratios: it is mainly to investigate the water absorption. The lower the water absorption, the better. Ceramic products have certain adsorption and permeability to water. If water is sucked into ceramics, it will produce a certain expansion, which is easy to make the glaze of the ceramic surface crack due to expansion. Especially for the toilet, if the water absorption is high, it is easy to suck the dirt and odor in the water into the ceramics, and the odor that cannot be removed will occur over time
