Causes of White Crystals on Wearable Floors

The main ingredient in concrete is calcium silicate (weak acid strong alkali salt), which reacts with water to form free calcium, silicic acid and hydroxide. The loose porous structure of concrete determines the concrete has a certain moisture content. When the water in the wearable floor is large enough, under the effect of capillary pressure, the water can rise up to about 10cm along the capillary hole. At this time, the salt in the concrete is pulled out of the concrete by the water and the hydroxide in the concrete. Calcium, sodium, potassium and other substances will also be dissolved in water as a carrier. After reaching the surface of the wear-resistant floor, these substances remain on the concrete surface as the water evaporates, forming white powder crystals, or reacting with carbon dioxide in the air to crystallize on the surface of the concrete to form white hard blocks. The wear-resistance floor efflorescence is formed in this way

Position measurement

Position sensors are used in a wide range of automation and measurement applications. A key step in selecting a suitable position sensor is understanding the requirements of sensor size, resolution, repeatability, accuracy, mounting constraints and environmental ruggedness. This paper discusses the available position sensing technologies and concludes with a key feature comparison.

Linear position sensors measure the distance between an object and a point of reference, as well as changes in position. They do this by converting displacement into an electrical output. A wide variety of measurement principles can be used to let you make precise and reliable measurements for a broad range of applications. Linear position sensors and measurement systems are used in industrial applications as well as in scientific laboratories.

Within their specified measurement range, LVDT sensors provide excellent linearity. They are capable of detecting very small changes in position and have virtually unlimited resolution. As a result, LVDT sensors are also suitable for measuring high accelerations and high measurement cycles.

Linear inductive position sensors are durable, long-lived, and especially stable under temperature fluctuations. That means they are ideal for measuring linear travel in almost any industrial setting – especially with hydraulic or pneumatic applications.
