Working Principle of Automobile Paint Scratch Tester

The automobile paint scratch tester is a test equipment independently developed and produced by our company. It has high-cost performance. It is carefully designed and manufactured according to the relevant provisions of GB9279-2015 "Paint and Varnish Scratch Test" and ISO 12137-2 "Determination of Scratch Resistance of Paint and Varnish". It is used to determine the scratch resistance and scratch resistance of a single coating or composite coating system of paint and varnish or water-based wood paint under standard conditions.

Established in 2012, Qinsun Instruments Co., LTD focuses on the research and development, design, and production of textile testing instruments. It provides textile testing instruments and services to academic research units and testing institutions. Qinsun is currently one of the most competitive and R&D-capable manufacturers of textile testing instruments in China, with an R&D team composed of experienced engineers. We are dedicated to serving our customers with all our hearts and striving to promote technological innovation in textile testing instruments.

Main parameters:

Motor power: 60W

Scratcher moving speed: 3cm/s

Scratcher head radius: 0.5mm

Test load: 50g~2000g

Power supply voltage: AC 220V 50Hz

Working principle:

A large speed ratio and large output torque gear reducer are used to ensure that the moving speed of the scratcher is constant under different test loads so that the test results have higher accuracy. At present, two kinds of substrate tests can be done. One is to test the scratch resistance of the coating of color paint and varnish water-based wood paint. The substrate is metal. Whether the paint film is scratched can be intuitively obtained through the indication of the voltmeter on the instrument. The other is to test the scratch resistance of water-based wood paint. The substrate is wood. Whether the paint film is scratched can be obtained by observation with the naked eye or a magnifying glass.

Advantages and features:
