Scratch Principle:</st Melt

This test method is used to test the ability of surface materials to resist damage caused by scratching fingers. According to the nails or other hard objects that may contact the material, scraping fingers of different materials are used to act on the surface of the sample with a certain pressure according to the specified direction, stroke and speed, and the scraping head and the sample make a relative movement, resulting in one-way, non-reciprocating linear scraping path, the scratches are kept parallel. The final assessment of the scratch sensitivity of the material, the color difference between the scratched area and the oscratched area, or the minimum scratch force when the sample surface is damaged.

Test principle:

1. Scratch test

One stroke, the pressure can be Adjustment, test speed can be preset, stroke can be set by crank (other cranks are also available), universal adapter can install customer\'s own tool or standard tool.

2. Cross-cut test

One stroke, adjustable pressure, preset test speed, set stroke per crank (other cranks are also available), cross-cut distance Manually move the sample laterally by a ruler mounted on the slide

3. Abrasion resistance test

The number of reciprocating stroke cycles can be preset and the printing speed can be adjusted. solid friction media, with round and square adapters available, for virtually any type of test.

Many individual tests are also possible on request. Potencyle customers are manufacturers (R&D/QC) and production (incoming/QC) whose products are occasionally or continuously subject to friction, such as plastics (light switches, computer monitors, furniture, car interiors, etc.), leather (used in shoes, clothes, belts, etc.), textiles (passenger seats used in various functional or protective fabrics or seat belts, etc.).

Basic composition:

The instrument consists of a motor drive mechanism, a scraper part, a sample clamp and fixing device, etc. . Scraper components include scraper brackets, scraper fingers, scraper sleeves, pressure devices (weights and weight support rods), etc.
