The final result of tile paving is determined by both the tile product and the paving construction. We know that the tiles need to be inspected and checked before being laid, but at the same time, we must not forget that we need to pass the inspection after the paving. Many homeowners often look at it and touch it when they check the paving effect. They find that there is no big problem. It is important to know that such acceptance is very irregular.
First, the tile paving appearance inspection
Tiles are commonly found in the wall of the bathroom and the floor of the living room. As one of the important "faces" of the home, the first thing to check after the tile is laid is its appearance.
1, check whether it meets the design requirements
First check whether the tile paving is in accordance with the design requirements. For example, if the owner asks for a diamond-shaped diagonal paving, then the method of cross-tiling or vertical paving cannot be used. In addition to the paving method, check whether the tile is laid in the correct direction, whether there is reversal; whether the tile and waistline are in the correct position, whether there is a bias or a height error.
2, check if there is a scratch gap
During the tile laying process, it is easy to scratch or damage the tile due to careless construction. At the time of acceptance, it is necessary to first check whether the surface of the tile has scratches or stains that are difficult to remove, and whether the brick surface has broken and collapsed angles.
3. Check for crack cracks
Generally, when there is natural light exposure during the day, use the method of eye and hand to check whether there is crack crack on the brick surface. Crack refers to the cracking of the surface of the brick surface, but the bottom of the tile is intact, and the hand touch has a slight feeling of cutting hands; the crack refers to the crack of the whole brick surface from the surface to the bottom, and the hand touch feels obvious cutting hands.
4, see if the gap is even
In order to cope with the problem of thermal expansion and contraction of the tile, as well as ensuring the flatness of the tile, the seam between the brick and the brick is required when the tile is laid. At the time of acceptance, it is necessary to check whether the gap of the tile is even and beautiful. Generally, the width of the brick is 1 mm and cannot exceed 2 mm. Special effects can also widen the gap, such as 5mm. In addition, check the tightness of the edge of the tile.
Second, check the horizontal and vertical
It is necessary to check the flatness and verticality of the tile paving, because if the tile is not flat, it will affect the appearance on the one hand, and affect the placement of the furniture on the other hand, so that it cannot be placed closely against the wall or unevenly placed. . How to check the flatness of the tiles? This requires a variety of flatness acceptance tools.
1, verticality detection
Tiles are often placed on the walls of the bathroom and kitchen, and it is necessary to check that the walls are horizontal and vertical. Let's first look at how to check the verticality of the tile facade. The 2M can be used to check whether it is vertical, but the deviation can not be accurately measured, and the deviation can be detected by using the 2M vertical measuring ruler.
Close the left side of the vertical measuring ruler to the measured surface, and then wait for the pointer to stop swinging itself, then read the scale value indicated by the pointer. This value is the deviation of the perpendicularity of the measured surface, and each grid is 1mm. The verticality of the facade of the tile is generally within 3mm.
2, flatness detection
When detecting the flatness of the tile, it can be detected by a vertical measuring ruler, or it can be detected by a 2M ruler plus a wedge feeler. When the latter method is used, the side of the ruler is pressed against the surface to be measured, and the gap size is detected by a wedge-shaped feeler.
Each point should be tested at three points, that is, a vertical point, and intersecting each other 45 degrees in the home position, taking the average of the three points. The flatness error of the tiles shall not exceed 2mm, and the height difference between adjacent bricks shall not exceed 0.5mm.
3, yin and yang angle squareness check
The wall surface of the tile is covered with yin and yang. It is necessary to use the yin and yang square to detect the squareness of all the yin and yang angles. According to the national requirements, the deviation of the yin and yang angle should not exceed 3 mm.
When testing, open the square ruler, use two hand-held square feet to closely touch the two sides of the tested positive angle to see the state of the scale pointer. When it is at “0â€, the squareness is 90°, that is, the reading is “0â€; When the scale pointer deviates to the left of “0â€, the angle is greater than 90°; when the scale pointer deviates to the left of “0â€, the angle is less than 90°, and the deviation is several squares, which is a few millimeters.
4, slope inspection
The slope inspection mainly involves the laying of floor tiles, and the kitchen floor, balcony and floor draining kitchen floor tiles should have sufficient self-drainage inclination. The slope should meet the requirements of no flooding and no water accumulation.
At the time of acceptance, the floor tiles must be tested for water, especially when installed in the bathroom or kitchen. It should be tilted to the floor drain so that the water can flow faster and drain faster. When checking, see if the running water is running out quickly, and pay attention to see if the tiles leak. When checking the ground for leaks, it is recommended to pour water several times and observe it for a while after splashing water.
Reminder: In addition to the above-mentioned tile quality acceptance method, in addition, tile empty drum inspection is also required. After the tile paving is completed, the owner can judge the quality of the home tile paving according to these inspection methods. If there are more serious problems, you can ask for timely rework.

Plastics materials are a group of synthetic materials that have become essential in today's world due to their versatility, durability, and low cost. These materials are used in a wide range of applications, from packaging and consumer goods to construction and automotive industries.
There are various types of plastics, classified based on their properties and the manufacturing process. These include polyethylene, polypropylene, polystyrene, polyvinyl chloride, nylon, and polycarbonate, among others.
Polyethylene is the most commonly used plastic and is often used in packaging materials such as plastic bags and containers. Polypropylene is similar to polyethylene but is more rigid, and thus, often used in products that require a stiffer material, such as automotive parts and furniture.
Polystyrene is a rigid and transparent plastic that is often used in products such as disposable cups, cutlery, and packaging materials. Polyvinyl chloride, commonly known as PVC, is a popular plastic for construction materials such as pipes, electrical cables, and window frames.
Nylon is a strong and flexible plastic used in various applications, such as clothing, carpet fibers, and mechanical parts. Polycarbonate is a durable and transparent plastic often used in products such as safety goggles, aircraft windshields, and electronic device screens.
While plastics have revolutionized various industries, the disposal of plastic waste has become a significant environmental concern. Recycling and proper disposal of plastics materials are crucial to reducing plastic pollution and preserving the environment for future generations.
Overall, plastics materials have significantly impacted modern society, providing solutions for various industrial and consumer needs. As research and innovation continue to advance, it is expected that even more sustainable and eco-friendly plastics materials will emerge.
