There are many types of tiles, and different tiles vary in size, texture, and functional advantages. Our common focus on ceramic tiles is in their environmental protection, water absorption, and other aspects. But do you know that tiles are also graded? So what are the tile classifications ? The following Xiaobian gave everyone the knowledge of classification of tile classification , so that everyone can easily understand how to choose different tiles when decorating different occasions. What are the tile classification? According to the radioactivity of ceramic tiles, the grades of tiles are divided into A, B, C and so on. 1, A level. Class A is not limited in scope of use and can be used in various places of home renovation. Therefore, the environmental performance of indoor floor tiles must meet Class A standards. The national standard for the radioactivity of tiles is GB6566-2001. The radioactive specific activities of natural radionuclides Ra-226, Ru-232, and K-40 in the class A decoration materials satisfy the requirements of IRa ≤ 1.0 and Ir ≤ 1.3 at the same time as class A decoration materials. 2, B level. Class B decoration materials do not meet the requirements of Class A decoration materials but at the same time meet the requirements of IRa ≤ 1.3 and Ir ≤ 1.9 are Class B decoration materials. Class B decoration materials shall not be used for the interior surfaces of Class I civil buildings, but may be used for the exterior surfaces of Class I civil buildings and the interior and exterior finishes of all other buildings. 3, C level. Class C decoration materials do not meet Class A and Class B decoration materials but Class C decoration materials meet the requirements of Ir ≤ 2.8. Class C decoration materials can only be used for exterior finishes of buildings and other outdoor uses. Granite with Ir>2.8 can only be used in places where humans are rarely involved, such as steles, seawalls, and bridge piers. Graded according to national standards, tiles can be divided into two levels: 1, A grade A grade is the best grade, A grade is divided into AAA grade, AA grade and A grade, AAA grade is the best grade. 2. Grade B Grade B products are products that have slight flaws. Conclusion : Regardless of whether tiles are divided in accordance with the radioactivity of tiles or standard regulations, we can find that different tiles still have their own fundamental differences. The above is a brief introduction to the classification of tile grades , and I hope to help you. For more information, please visit this website. Stay tuned.
