What Are The Test Methods For Taber Coating Abrasion Resistance? This is the case

Product introduction

Wear and tear is one of the forms of material failure and collapse. The advantages and disadvantages of wear resistance of various materials are very important for product quality evaluation and control. There are corresponding wear test methods for different materials. For example, the Japanese industrial standard JIS H8503 prescribes the test method for the abrasion resistance of metal coatings; and the American Material Testing Protocol Standard ASTM D968-93 and ASTM D658-81 respectively prescribe the use of the falling sand method. BS-EN 660-2 and sandblasting method to determine the abrasion resistance of organic coatings; while the international standard ISO7784.2-97 uses the rotary friction rubber wheel method to measure the abrasion resistance of paints and varnishes. Standard GB/T1768-79 Determination of abrasion resistance of paint film; It\'s not difficultto see that at present there are various methods of testing the wear resistance of coating coatings at home and abroad, each with its own characteristics;

Common test methods for coating wear resistance :

1. Rotating friction rubber wheel method (Taber test), which can be widely used in coatings, coatings and metal, non- The abrasion resistance test of metal materials, but the rubber grinding wheel used for grinding needs regular dressing and timely replacement.

2. Falling sand erosion test method, i.e. using natural quartz sand from a specified place of origin as an abrasive, free falling from a certain height through the tube of the tester and the surface of the sample to reduce wear. The volume consumed by the coating per unit thickness of the specified area and the abrasion resistance of the coating is evaluatedd by calculating the wear resistance coefficient.

3. Sandblasting impact test method, used to measure the wear resistance of organic coatings.

4. Reciprocal motion wear test method, the test conditions of this method are easy to control, so the repeatability of the test results is good, and except for coatings, this method has been widely used Wear resistance test for plastic, rubber and metal materials.
