Interpretation of Multifunctional Scratch Resistance Test Instrument

Author: Released in:2017-05-12 Click:153

Taber Multifunctional scratch resistant tester is suitable for all kinds of automotive interior materials such as plastic, rubber, leather, fabric, coating materials, non-coated materials and other composite materials such as scratch resistance test. Multi-functional scratch-resistant instrument is applicable to all kinds of automotive interior materials scratches performance test equipment, instrument integration of the three domestic testing standards (five fingers scratch method, 100 grid method, plastic scratch scratch method).

Scratch principle:
This test method is used to test the ability of surface materials to resist damage caused by scraping fingers. According to the material may be used in contact with the nails or other hard objects, the use of different materials, scraper, in accordance with the provisions of the direction, travel, speed, with a certain pressure on the sample surface, scraping the head and the sample to do relative movement, Unidirectional, non-reciprocating straight line scratching the track, scratching between the parallel. Final evaluation of the scratched sensory grade of the material, the color difference between the scratched area and the unscrewed area, or the minimum wiping force when the surface of the sample is damaged.

Taber 710 Finger Scratch Tester Compliance Standards: GB / T 2918, GB / T 6151, GB / T 8424.3, PV3952, BMW GS97034-2, BMW GS97034-9, GMN 3943-2003, FLTM BN 108-13, STD1024- 3113, GMW 14698-A, GMW 14688

Instrument features:
1. Instrument by the motor drive mechanism, scraping components, sample clamping fixtures and other components.
2. Scratch components include scraper brackets, scraping fingers, scraping finger sets, presses (weights and weight support bars).
3. The instrument can be free to install, replace, disassemble different specifications of the scraping fingers, can be carried out under different load uniform one-way linear scratches the movement.
4. The use of embedded systems, man-machine interface operation of the test process for automatic control, the use of precision servo motor, ball screw drive, for the relevant standards in the scratch speed control accuracy has a decisive role.
5. Use tungsten carbide material to do scraping, increase the instrument life.
6. The use of aluminum and stainless steel, the appearance of simple and lightweight and corrosion-resistant.
