Clay characteristics of Letao village in Quanzhou

1, excellent freeze-thaw resistance: when the water absorption reaches 10%, porcelain has been completely frozen and cracked after freezing and thawing at-15℃ for three times, while ceramic tiles will not freeze and crack after freezing and thawing at -45℃ for 50 times.

2. Good light pollution resistance: tiles can completely refract more than 90% of light, which has a good effect on protecting people's vision and reducing light pollution.

3. Good sound absorption: Because ceramic tiles are rich in a large number of uniform and fine openings, they can completely or partially refract sound waves and take them outdoors to reduce noise and eliminate indoor echoes. They are excellent materials for creating a good living environment in cities.

4. Good air permeability and water permeability: The advantages of air permeability and water permeability of ceramic tiles have been fully demonstrated in today's green civilization, and its quaint charm is integrated with the natural landscape, reflecting the harmonious dialogue between man and nature.

5. Good weather resistance and corrosion resistance: With the aggravation of industrial pollution, the acidity of rainwater is increasing day by day, and many building materials are eliminated because they cannot accept this test. Pure natural processing procedures make ceramic tiles contain only a small amount of chemical impurities, and their internal structure is not easily affected by acid rain. The alkali corrosion resistance of ceramic clay is incomparable with other materials.
