Application of Scratch Tester

Taber 551 is used to evaluate the shear, scratch, planing, scraping, and carving properties of materials. Its application areas include rigid organic materials, coating adhesives, powder coatings, anodized materials, soft metals, plastics, and glass, among others. It can also be used to test the adhesive quality of the same material, protective coating, and the ultimate performance of similar materials. Taber 551 is easy to operate and mobile, capable of testing materials ranging from 1/2 "to 4" thick square or circular shapes.

Scratch tester operation

Before installing the sample, it is necessary to adjust the scale to the appropriate height according to the thickness of the sample. Install precision cutting tools on the scale and place them on the sample. Start the instrument and rotate the turntable at a constant speed to ensure accurate measurement results. By changing the load of the cutting tool, you can evaluate the shear or scratch resistance of the material.

The scale design of the instrument allows it to be level with the sample and turntable, and can be raised or lowered according to actual needs. In addition, the scale can be lifted and suspended in the air to facilitate the operator in removing the sample. By changing the position of the sliding weight, the total load on the sample can be adjusted within the range of 0-1000g. The cutting tool can choose to use tungsten carbide cutting tools or conical drill stones.

The test results can be visually judged using a randomly equipped 10x magnifying glass, and users can also observe using a high-precision optical microscope.
