The falling sand abrasion Tester is used to test the abrasion resistance of organic coatings under standard conditions. This method tests the abrasion resistance of the coating by dropping the abrasive from a specified height onto the coated test panel through the conduit until the substrate of the test panel is visible. The abrasion resistance of the coating on the test plate is represented by the amount of abrasion per unit film thickness. The test method of this instrument conforms to the American industrial standard ASTMD968-83, which tests the wear resistance of organic coatings by the falling sand method and the construction industry standard JG/T133-2000, which is used for building aluminum profiles and aluminum plates. test requirements.

The falling sand wear Tester is designed and manufactured according to ASTM, and it is easy to operate. A switch to control the flow of sand is set near the conduit. There is a sand box for placing the test plate at an angle of 45 degrees to the vertical position at the lower part of the conduit. There are clamps on both sides of the sand box to tighten the test plate. There is a height adjustment nut on the lower part of the instrument, which is used to adjust the distance from the pipe to the painted surface. There are adjustment screws at the bottom of the instrument to properly adjust the sand flow center position.
