Fabric Abrasive Tester Martindale Flat Grinder Fabric Flat Grinder

Author:QINSUN Released in:2023-03 Click:24

[Product Description]:
This instrument is suitable for testing the pilling degree of substances such as GB/T4802.2, ASTM D4970, ISO12945-2, etc. The principle: under a given pressure, the round sample is 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.

【Comply with standard】
GB/T4802.1-1997, ASTM D4970, ISO12945-2 and other pilling degree tests of fabrics; GB/T13775, ASTM D4966, ISO12947 and other fabric abrasion resistance tests.

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

【Operating principle】
Under a certain pressure, the round dust sample is compared with the standard abrasive according to Li Sharu The trajectory of the (Lissajous) curve rubs against each other, making it sample is damaged, and the abrasion resistance of the fabric is expressed by the number of times the sample is damaged.

【Technical characteristics】
Martindale wear-resistant testing machine is designed by absorbing the advantages of similar instruments at home and abroad The appearance is beautiful and generous, it has a touch screen, the interface is easy to understand, and the operation is simple. 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 ensure the improve test efficiency. The instrument is tooequipped 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.

【Precautions for Martindale Abrasion Tester Operation】:
1. The friction cloth cannot be used repeatedly, and a friction cloth must be replaced each time a test is completed;
2. Sheep The felt can be used repeatedly. If the surface is worn or stained, it should be replaced and can be used on both sides;
3. The insole must be dressed first and then the Martindale abrasion test has been carried out;
4. The test is completed If the surface table of the final sample shows abnormal phenomena such as abrasion, broken yarn, fluff, severe pilling and severe wear, it will be judged as non-qualified.
5. When preparing sampleers, special attention should be paid to prevent hair changes at the cutting edges, to avoid unnecessary loss of quality and appearance changes.
6. Pay attention to operating specifications and personnel safety during instrument operation.

【Martindale Abrasion Tester Maintenance】:
1. The instrument should be cleaned and cleaned regularly to ensure the cleanliness of the test instrument;
2, Check the test instrument regularly to see if there is any abnormality;
3. During the use process, each user should use it according to the correct use method, and should not use it in violation of the regulations, so as not to damage the instrument and shorten the service life of the instrument;
br>4. After using the test instrument, each user should arrange the instrument and clean the instrument accordingly to ensure that the instrument is clean;
5. When the instrument is not in use, it should be placed. The power of the instrument is turned off and the instrument is kept clean continuously.
