Martindale abrasion tester

Author:QINSUN Released in:2023-03 Click:125

[Product Description]:
This instrument is suitable for testing the degree of pilling of substances such as GB/T4802.2, ASTM D4970, ISO12945-2, etc. The principle: Under a given pressure, the round sample rubbed against the fabric of the same material with the trajectory of the Lissajous figure, and after reaching the specified number of revolutions, the pilling level of the sample is evaluated. It is also suitable for the abrasion resistance test of GB/T13775, ASTM D4966, ISO12947 and other fabrics. The principle: Under a certain pressure, the round fabric sample rubs against the standard abrasive according to the movement trajectory of the Lissajous curve, resulting in damage to the sample. The abrasion resistance of the fabric is expressed by the number of times the sample is damaged performance.

【Main Features】:
The instrument is designed by absorbing the advantages of similar instruments at home and abroad. The system is usingof two counting methods, which are intuitive and easy to set up. Eight stations are tested simultaneously to improve test efficiency. The instrument is also equipped with two types of Lissajous (Lissajous) 24mm × 24mm, 60.5mm × 60.5mm movement track and various supporting accessories, which can be adapted to different test methods and standards.

【Scope of application】:
Martindale Abrasion Tester is used for textile and membrane materials for abrasion resistance, wear and appearance changes (pilling) performance test

 Working principle:
Under a certain pressure, the round dust sample is compared with the standard abrasive according to the Lissajous curve. The movement trajectories of the samples rub against each other, resulting in damage to the sample, and the abrasion resistance of the fabric is expressed by the number of times the sample has been damaged.

GB/T4802.1-1997, ASTM D4970, ISO12945-2 and other tests of fabric pilling degree;
GB/T13775, ASTM D4966 , ISO12947 and other wear testssolidity of substance.

【Technical Characteristics】
Martindale wear-resistant testing machine is designed by absorbing the advantages of similar instruments at home and abroad. to understand the interface and simple operation. The microcomputer system adopts two counting methods, which are intuitive and generous, and easy to set. Six stations (or nine stations) can be tested at the same time to improve the testing efficiency. The instrument is also equipped with two types of Lissajous (Lissajous) 24mm × 24mm, 60.5mm × 60.5mm movement track and a variety of supporting accessories, which can be adapted to different test methods and standards. < /p>
