How to identify the quality of ceramic tiles:

The first point: look

Looking mainly refers to checking the surface quality of ceramic tiles. The following is based on glazed tiles and vitrified tiles. Two aspects to introduce: 1. Glazed tiles:

Mainly check whether there are black spots, bubbles, pinholes, cracks, scratches, stains, missing edges, missing corners and other surfaces on the surface of the tiles. defect! Bricks with many defects are of relatively poor quality! 2. Vitrified tiles:

In addition to checking whether there are black spots, bubbles, pinholes, cracks, scratches, stains, missing edges, missing corners and other surface defects on the vitrified tiles, Also pay attention to whether there are defects such as missing polishing and grinding. No matter what brand of product it is, the base body should have the brand mark of the ceramic tile. Check the base base trademark mark. Products produced by regular manufacturers have clear product trademark marks on the base base. If there is none or it is particularly blurry, it is recommended to choose carefully. ! The second point: Weighing

is to weigh the weight and test the feel of the ceramic tiles. For products of the same specifications and thickness, bricks with good quality and high density will feel heavier. On the contrary, products with inferior quality will feel heavier. lighter.

Explain that the quality of ceramic tiles is not directly related to the thickness of the ceramic tiles. It mainly depends on the density of the ceramic tiles!

The third point: listen

By tapping the tiles and listening to the sound, you can identify the quality of the tiles. The following is an introduction based on the two aspects of kitchen and bathroom wall and floor tiles and vitrified tiles: (1) Wall tiles or small-sized ceramic tiles

Usually separate the five fingers of one hand to drag up the tile, and tap the face of the tile with the other hand. If the sound produced has a metallic texture, the quality of the tile Better, if there is no metallic sound, the tiles are of poor quality!

The tapping method is as shown below (2) Large floor tiles (vitrified tiles or antique tiles are used on floors such as living rooms)

Use one hand to lift one side of the tile, and use the other hand to lift the tile. Knock the middle of the ceramic tile with the upper palm of your hand. If the sound is thick and the echo is long, like the sound of a copper bell, then the ceramic tile has a high degree of porcelain, strong wear resistance, high flexural strength, and low water absorption. It is not easy to be polluted. If the sound is turbid and there is no echo, the degree of porcelain is low (even cracks exist), the tile body is not fully calcined, the wear resistance is poor, the flexural strength is low, and the water absorption rate will be higher. Such vitrification Bricks are highly susceptible to contamination.

The tapping method is as shown in the fourth point: combine products of the same specification and model, take out 4 pieces at will, and lay them. Through this step, you can check the size, flatness, and right angle of the tiles. aspects of the problem. (1) Check the size of the tiles

Take out two pieces of the same type of product and place them on the horizontal surface. Use the tips of both hands to slide back and forth along the edges of the tiles. If there is no obvious sluggish feeling when sealing, it means that the size of the ceramic tiles is relatively good and the error is small. The smaller the size error, the better the paving effect of the ceramic tiles will be! On the contrary, if there is an obvious feeling of sluggishness in the tiles, it means that the size error of the tiles is large, which will affect the effect of paving! (2) Check the flatness of the tiles

Place two or four tiles of the same type on a flat surface according to the same pattern, and slide your hands back and forth on the tile surface. If you pass by the tiles, If there is no obvious sense of height in the joints, it means that the flatness of the tiles is good. On the contrary, it means that the flatness of the tiles is poor, which will affect the overall effect of the tile paving. If the flatness of the floor tiles is poor, in serious cases, it will trip. Down! So this needs attention. (3) Check the flatness of ceramic tiles

Nowadays, ceramic tiles are mainly rectangular. Each corner of the ceramic tiles is a right angle. If the right angle is poor, it will also affect the paving effect of the ceramic tiles. Take four tiles of the same type and splice them together. If the joints of the four tiles cannot be tight and there are always gaps in one or two joints, it means that the right angle of the tiles is not particularly good.

The fifth point: The test is mainly aimed at the anti-slip problem of floor tiles

For floor tiles, the materials are mainly divided into two types: vitrified and glazed. Regarding the anti-slip problem, the common practice now is to add water to the brick surface, and then step on it to see if it is slippery. This approach is actually not completely appropriate, because some ceramic tiles, especially vitrified tiles, after adding water, It will feel more involved. This principle is a bit similar to adding water between the glass. If you want to lift the glass, you will find it very difficult because the water squeezes out the air in the middle, making the bricks and shoe uppers in closer contact, so it feels Even more involved, some vitrified tiles feel slippery when no water is added. In this regard, my personal suggestion is to try both adding water and not adding water.
