1, inconsistent size observation method will be more than four tiles on a flat surface to see if the diagonal alignment, such as the right, the size is certainly inconsistent.
2, the brick surface leveling observation method will be two pieces of the front together, if the gap can be seen on both sides of the brick is convex phenomenon; the middle can see the light is the brick concave phenomenon, close together is the flatness Qualified brick.
3. Chromatic aberration and surface defect observation method to draw a number of bricks together, from different angles to see its color shade, shade, pattern is complete, similar, or from multiple angles to observe whether the brick surface pinhole, glaze, lack Glaze, bumps and other defects.
It is easy to break during the renovation process, the damage rate is as high as 50%, and the durability after decoration is poor. The strong strength of the tile is strong in crack resistance. The minimum standard compressive strength of the national standard polished tile is 27MPa, which is equivalent to 400 80kg people standing on a foot-sized area. However, many dealers have found that the foundations are not flat or the bricks are cracked. Some even engage in tricks such as throwing bricks and bricks. According to the above data analysis, it is completely impossible. These are all tricks for consumers. Because ceramics have considerable strength after being fired at a high temperature of about 1200°C, these bricks, which are dry and strong, cannot be distinguished by human visual and hearing. The best way to learn more about the strength of a tile is to use a tile flaw detector to test it.
In accordance with the above method, consumers can avoid the impact of false sales, if you want to further select high-quality tiles, you must use accurate and fast equipment, carefully selected for the decoration, careful planning.

Pneumatic valve is a kind of valve controlled by air pressure, which is widely used in industrial automation control system. Its main applications include the following aspects:
1. Fluid control: pneumatic valve can be used to control the flow and direction of liquid or gas, such as controlling the flow in the pipeline, exhaust gas emission, etc.
2. Pressure control: pneumatic valve can be used to control the pressure of fluid, such as controlling the pressure of compressed air, regulating the pressure in the hydraulic system, etc.
3. Temperature control: pneumatic valve can be used to control the temperature of fluid, such as the temperature of heating or cooling system.
4. Automatic control: pneumatic valve can be linked with sensors, PLC and other equipment to realize automatic control, such as automatic production lines, robots, etc.
5. Safety control: pneumatic valve can be used for safety control, such as controlling emergency stop, preventing overload, etc.
In general, pneumatic valve plays an important role in industrial automation control system, which can improve production efficiency, reduce costs, and ensure safety.
