Method to Measure Flatness of Tile Surface.
Place four or more products in the same direction as the bottom mark (pattern) on a flat sand surface, reserve an expansion gap, and see if the four sides of the junction are flat and there is no obvious “kicking” phenomenon.
Use a ruler greater than or equal to the length of the side of the brick and place it 5 mm away from the edge of the tile. Use an appropriate feeler, from a large value to a small value, and insert a gap between the ruler and the brick surface. The deformation value is the deformation value of the product.
It is not correct to observe and measure the flatness of two products face-to-face; it is not correct to use the eye to visualize, or to use two bricks to rotate on a flat floor or table. The commonly used detection method is to use a ruler to detect.
Simply detect the deformation of the tiles: Two people will use the two deformed tiles by hand to butt the tiles with bricks to see if they are flush. If there is a large difference in the deformation of the two bricks, use 1 method to test, if you want to know whether the product's deformation value exceeds the standard, then use method 2 to detect.
According to the requirements of different types of products, gaps must be reserved when trial products are placed. In particular, the characteristics of products such as antique tiles, elegant sandstone, and natural surfaces determine that a gap of 5-15 mm must be reserved when paving.
