I heard that some ceramic tiles can sterilize besides formaldehyde. Is that true?

It's really true. To tell the truth, the function should be there, but it has not been recognized by the authoritative department, and there are still doubts. As for whether negative ion tiles can eliminate formaldehyde, it is even more doubtful. To tell the truth, the function should be there, but it has not been recognized by the authoritative department, and it is still in doubt. As for the negative ion ceramic tile can eliminate formaldehyde, it is even more doubtful that there will be a warranty contract in each barrel of soda gram products for a period of 20 years. It is recommended that the owner fill it out carefully. Alkaline tile adhesive is not only a brick-removed product, but also a conscience product, which really puts the interests of the owners first. To tell the truth, the role should be there, but it has not been recognized by the authoritative department, and there are still doubts. As for whether negative ion tiles can eliminate formaldehyde, it is even more doubtful that negative ions, formaldehyde adsorption, sterilization and bacteriostasis, health care and calming the nerves ... Now many businesses use "functional tiles" as gimmicks to promote sales. "Antibacterial tiles", "sound insulation tiles" and "heating tiles" look like ordinary tiles, but they claim to have special functions such as purifying air, sterilizing and antibacterial, health care and calming the nerves, and releasing negative oxygen ions. It's hard to draw a conclusion, but most salespeople can't prove the function and qualification of these tiles, but they are true. Many consumers also hold a wait-and-see attitude towards it.

For ceramic tiles, the testing items listed in national standards include hardness, water absorption and anti-pollution performance. , such as the content of negative ions and titanium ions, and how to detect them? There is no corresponding standard in China. When buying ceramic tiles, these standard items should be the performance indicators of general concern, and other functions do not need to be realized through ceramic tiles. Since this sentence spread on the Internet, people who are increasingly pursuing health are very worried: Does tile radiation really exist and how harmful it is to human body? In fact, radiation is inevitable whether it is the influence of the minerals of the tiles themselves or the influence of processing additives, such as zirconia added in ultra-white tiles or uranium and potassium contained in dark glazes. However, because ceramic tiles are only synthetic natural materials, the radiation is far less than that of natural materials, and their radioactivity is basically kept at a low level. Moreover, the tiles on the market have passed the national radiation standards. As long as it is properly laid and well ventilated, the health of users will not be harmed. , tile purchase method 1. Look at the appearance. Ceramic tiles should be uniform in color, with good surface finish and smoothness, regular in periphery, complete in pattern, and free from color difference, deformation, black spots and obvious impurities.

2. Listen to the sound. Tap with a hard object, the clearer the sound, the higher the porcelain degree and the better the quality. You can lay the brick flat with your fingers, and tap it with your forefinger or middle finger with your other hand to listen to the sound of the brick. If the sound is clear and pleasant, it is the top grade, and the sound is dull and turbid.

3. weigh yourself. Judging the density by weighing the components, the heavier the same volume, the better.

4. Drop test. Water or tea can be dripped on the tiles.
