Working Principle of Automobile Paint Scratch Tester

2025/02/12

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.

As a modern technology enterprise integrating R&D, manufacturing, sales, training, and services, Standard International Group (HK) Limited is committed to delivering more testing instruments to the market, providing testing instruments for textiles, leather, combustion, automotive interior and exterior trims, material environmental climate aging, etc., and non-standard customization is also acceptable. Targeted tests can be carried out according to customer requirements before purchase to ensure that the purchased instruments are applicable.

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:
