Number one: Look.
See mainly refers to check the surface quality of ceramic tiles, the following according to glazed tiles and vitrified tiles to introduce two aspects:
1, glazed tile:
Mainly depends on whether there are surface defects such as black spots, bubbles, pinholes, cracks, scratches, stains and lack of edges and corners on the surface of ceramic tiles! Bricks with many defects are of poor quality! No matter what brand the product is, the blank must have the brand logo of ceramic tile. Check the trademark mark of the blank. The product blanks produced by regular manufacturers have clear product trademark identification. If it is not or particularly vague, it is recommended to choose carefully!
Number two: OK.
It is to weigh and test the feel of tiles. For products of the same specification, bricks with good quality and high density feel heavier, whereas inferior products feel lighter.
The third point: Listen.
By tapping the tiles and listening to the sound, we can identify the quality of the tiles. This is the tile in the kitchen and bathroom.
(1) wall tiles or small-sized tiles
Generally, use one hand to separate the five fingers, pull up the tile, and use the other hand to hit the tile surface. If there is metal sound, the quality of tiles is better, but without metal sound, the quality of tiles is poor!
(2) Large floor tiles (the living room and other floors are glazed tiles or antique tiles)
One hand lifts one side of the tile, and the upper part of the palm of the other hand taps the middle of the tile. If the sound is rich and the echo is as long as the sound of knocking a copper bell, the ceramic tile has a high degree of porcelain, strong wear resistance, high flexural strength and low water absorption, and is not easy to be polluted. If the sound is turbid and there is no echo, the porcelain degree is low (even there are cracks), the ceramic tile blank is not fully calcined, the wear resistance is poor and the flexural strength is low.
The fourth point: fighting.
Randomly take out four products of the same specification and model and put them together. Through this step, we can check the size, flatness and right angle of the tile.
(1) Check the size of the tiles.
Take out two products of the same model and put them on a horizontal surface, and slide back and forth along the edge of the tile with your fingertips. If there is no obvious hand lag when passing through the sealed part of the tile, it means that the size of the tile is better and the error is small. The smaller the size error, the better the tile paving effect will be! On the contrary, if there is an obvious feeling of sticking tiles by hand, it means that the size error of tiles is large, which will affect the effect of paving!
(2) Check the flatness of ceramic tiles.
Lay two or four tiles of the same model on a flat surface according to the same lines, and slide back and forth on the surface of the tiles by hand. If there is no obvious sense of height after passing through the joint of the tile, it means that the flatness of the tile is better. On the contrary, it shows that the flatness of ceramic tiles is poor, which will affect the overall effect of tile paving. If the flatness of the tile is poor, it will trip people seriously! So this should attract attention.
(3) Right angle of ceramic tile
At present, the tiles are mainly rectangular, and each corner of the tiles is a right angle. If the right angle is poor, it will also affect the tile paving effect. Take four tiles of the same model and splice them together. If four tiles can't fit closely, there is always a gap in one or two joints, indicating that the right angle of the tiles is not particularly good.
Fifth point: try
As long as it is aimed at the anti-skid problem of floor tiles, the materials are mainly divided into vitrification and glaze. For the anti-slip problem of ceramic tiles, the usual practice is to add water to the surface of ceramic tiles, and then step on it to see if it slips. This practice is actually not entirely appropriate, because some tiles, especially vitrified tiles, will feel more related to their feet after adding water. This principle is somewhat similar to adding water between glasses. If you want to open the glass, because the water squeezes out the air in the middle, the brick and the vamp are in closer contact and feel more full, while some vitrified bricks feel slippery without water. My personal suggestion is to try both adding water and not calling water!
You don't have to go to the building materials market to buy tiles. They are also available online, and the price is still low, and the quality is the same as offline. We are the ceramic tile background wall. If you need help, please come to me and you will be satisfied!
