ASTM D 968 Falling Sand Abrasion Tester Coating Falling Ball Impact Tester

BGD 529 ASTM D 968 Falling Sand Abrasion Tester Coating Falling Ball lmpact Machine

1. Description:

The Falling Sand Abrasion Tester is used to test the wear resistance of organic coatings (such as aluminum-plastic composite panels or metallic paints, automotive paints, etc.) under standard conditions. Let sand particles of a certain size fall onto the test sample from a specified height through a conduit until the substrate is exposed. Weigh the amount of sand required to damage the paint film and evaluate the wear resistance of the paint film based on the standard amount of sand used per unit coating thickness.

The Falling Sand Abrasion Tester provided by Biaogeda Company is strictly manufactured in accordance with GB/T 23988-2009 "Determination of Abrasion Resistance of Coatings - Shakeout Method" and ASTM D 968. The dimensional deviation of each component is precisely controlled, and the main components are all made of high-grade wear-resistant stainless steel.

The funnel adopts a sector switch design, which is more convenient. (Other suppliers use the plug-in type.)

The height between the catheter and the test plate frame is adjusted by the special tools provided, which is more accurate

The height of the sand-dropping tank can be flexibly adjusted up and down by the bearing below
