The water absorption rate index

The water absorption rate index

2019-06-15



The so-called water absorption rate is an indicator for judging the adsorption and penetration ability of ceramic products to water. It is understood that after the water is sucked into the ceramic, the ceramic will have a certain expansion, as is the ceramic basin. This easily causes the glazed surface of the ceramic surface to crack due to swelling. It can be seen that the lower the water absorption rate, the better the quality of the ceramic product. According to the national water absorption rate standards, sanitary ceramics with a water absorption rate of less than 3% are high-grade ceramics. When purchasing, you should pay more attention to the manufacturer's instructions and try to choose products with low water absorption.
