Sand fall Tester

The sand falling tester measures the volume of sand required to wear through a coating by controlling standard sand particles to freely fall from a fixed height and impact the sample surface. It is used to evaluate the wear resistance of materials such as coatings and plastics, and to verify the product's abrasion resistance in quality control.
Selection
When selecting, consider the sand grain specifications and flow accuracy required by the testing standards. The sample fixture must match the shape and size of the object to be tested, and the instrument should have an automatic stop function when the sand grains are depleted. Verify that the calibration report issued by the metrology organization covers the key parameters.

Sand Abrasion Tester for detecting the wear resistance of thermal spray coatings
This article introduces the method of using a sand falling tester to evaluate the wear resistance of thermal spray coatings. Thermal spray coatings are widely used in fields such as machinery and aviation, with wear resistance being a critical performance indicator.
Sand Falling Test Apparatus for Measuring the Wear Resistance of Powder Coatings
The sand falling test instrument determines the wear resistance of powder coatings by simulating sand particle impact. During the test, abrasive material falls vertically from a specified height, continuously scouring the coating until the substrate is exposed. The wear resistance is evaluated based on the mass of abrasive material consumed.
