Problems solved by technology

However, some existing technologies only combine ordinary ceramics with other materials, and do not perform anti-static treatment on the ceramics themselves, resulting in poor anti-static performance.
Some products add conductive powder to the ceramic body and glaze, and fire at 1300 ° C to become an antistatic porcelain floor material. Although it has good antistatic performance, the amount of conductive powder added is large. And changed the existing low-temperature quick-firing production process of ceramic wall and floor tiles, the production process is complicated and the cost is high
