What are the hazards of “empty drums� Many people don't think about the empty inspection of ceramic tiles. I feel that it is a big problem. Is it true that tile empty drums are definitely harmful, otherwise it will not be out of the industry norm. Let Xiaobian tell you the common empty drum hazard! 1. The tiles at the hollow drum are not affected by force, and are easily broken when they are subjected to external forces in the future; 2. Empty drums may cause the tiles to gradually expand the range of empty drums in the days to come, and finally the tiles are lifted or fallen off; 3, the empty drum will lead to difficult wall drilling in the future, and easy to crush the tiles (such as when you are in the water heater, mirror, pendant, cabinet, bathroom cabinet); 4, the empty drum will cause water inside the bathroom floor and rot and smell (the reason why many people have smells in the bathroom is here); 5, the empty drum reflects not only the appearance, but also reflects the construction process may have serious problems (such as no brushing before laying bricks). "empty drum" self-test method The detection method of the empty drum is very simple. Generally, the five-point tapping method is adopted: the five-point tapping method is a well-known method for checking whether the tile has an empty drum phenomenon. The specific method is to find a metal object (the best tool is the construction site). Drill the drill bit or your own key, a small stainless steel spoon can also be used to knock the four corners and the center of the tile. If there are more than two points in the above five points, then it can be explained that the tile is not smudged. If there is space in the middle, it should be uncovered. However, it should be noted that the kitchen flue and the tiles on the wall of the cement board are not suitable for this inspection method, because the wall itself is not solid, so how to knock is also an empty sound.
