Car paint film scratch tester principle

　　The car paint film scratch tester is carefully designed and manufactured in accordance with the relevant provisions of GB9279-2015 "Scratch Test for Paints and Varnishes" and ISO 12137-2 "Determination of Scratch Resistance of Paints and Varnishes". It is used to determine the scratch resistance and scratch resistance of single or composite coating systems of paints and Varnishes or water-based wood paints under standard conditions.

　　Main parameters:

　　Motor power: 60W

　　Needle movement speed: 3cm/s

　　Needle head radius: 0.5mm

　　Test load: 50g~2000g

　　Power supply voltage: AC 220V 50Hz

　　principle:

　　Adopting a high speed ratio and high output torque gear reducer to ensure a constant speed of needle movement under different test loads, resulting in high accuracy of test results. At present, there are two types of substrate tests that can be conducted. One is to test the scratch resistance of water-based wood paint coatings of colored and clear paints. The substrate is metal, and 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, and whether the paint film is scratched can be observed by the naked eye or a magnifying glass.

　　Advantages and characteristics:

　　1. Have a strong after-sales service team;

　　2. Able to handle various issues in a timely and fast manner, relieving customers of any worries they may have;

　　3. Complete spare parts to solve the problem of long lead times when ordering spare parts;

　　4. Keep up with industry standards updates and provide textile testing instruments that meet the new standards in a timely manner.
