New technology for making ultra-thin wall and floor tiles

In the past, the production of ultra-thin wall and floor tiles below 5 mm was more difficult due to the fact that the green body was too thin and the packing density was poor (the contour line of the filling density distribution of the green body), which could easily cause warping of the burnt products. Uneven. It is reported that in June 2003, foreign countries introduced a new process for producing ultra-thin wall tiles. According to reports, this process can produce 2 to 3 mm wall tiles.
This process is very simple and can be achieved with only a slight improvement of the molding die. That is, on the lower mold of the forming mold, diagonally opposite regions are crossed, and numerous square and triangular projections are provided. The use of such a mold can form corresponding recessed holes in the same area on the bottom surface of the green body, eliminates the poor filling density of the green body, makes the density uniform, and the body undergoes a single firing or secondary firing without warping deformation. , uneven. In addition, after the kiln dried at 100 to 200°C, the glaze layer will not be uneven, and it will not be affected by the flatness of the crucible because it does not need to use crucible.
