Product Introduction

Martindale Abrasion Tester, also known as Martindale Abrasion Tester, is mainly used. It is widely used in the leather and textile industry for the friction resistance test of the test material. The method of using the Martindale Abrasion Tester for the test experiment in textile industry and leather industry is similar.

Based on the principle:

The Martindale Abrasion Tester is based on the design principle of J.G. Martindale and a test conducted in accordance with the Equipment Specifications of the Wool Industry Research Association. It uses standard wool felt as the friction object to rub the tested items such as cloth, etc. Of course, according to different test methods and different requirements, the friction object can be changed from standard wool felt to other materials such as sandpaper to test the wear resistance of leather. gender or mafrom depigmentation. The object under test is clamped with a cylinder and a standard weight (determined according to the test method is pressed on the friction object, driven by the vertical and horizontal eccentric wheels to produce a Lissajous curve, the purpose is to complete a multi-directional friction test For general footwear materials, the friction effect test during wear is usually performed by both dry and wet methods at the same time, to simulate the impact of rain on the upper material of the shoe or the influence of sweat on the inner lining of the shoe.

Test Method:

The Martindale Abrasion Tester can test a minimum of four samples at a time, and a maximum of nine samples at a time Each test position contains a protruding circle Shaped base, this base has a flat ring, which can clamp friction objects, etc. The object under test is clamped on the cylinder and a load (weight) is addedgd. If no weight is added, the weight of the flat plate is equal to that of the friction object. The pressure generated on the top is about 0.1342Kg/cm2 or 13.16Kpa. Different test methods can choose different weight (weight) test setups. The test specimen\'s seat is driven by the flat plate to produce a motion orientation of the Lissajous figure, but the axis of each test specimen\'s seat is on the flat plate. For free rotation, clamp a graphical sample of the tested object to the fixture and place a certain weight on it. After the clamp contacts the tested object and the friction material with a lower standard (cloth, sandpaper, etc. are determined by different test standards) to produce images. And produce a multi-directional friction. Each time a Lissaru figure is completed, the counter jumps 16 times and the time is approximately 20 ± 1 seconds.

Martindale Abrasion Tester Test Operation Steps:

1. Turn on the power and turn on the power switch on the side of the instrument;

2. Check 3 The positioning of the bearing pulley;

3. Set the desired speed;

a) Press the "*" key below the display to reset all individual counters;

b) Press the "0" key to reset the operation of a particular counter;

c) Press the "1" key to count only the operation of a particular counter;

d) Press the "2" Can clear the data displayed on a particular counter;

4. Will try The sample and the abrasive are placed in the sample holder or on the sanding table according to the requirements of different method standards;

5. Press the green button to start the test;

6. Set the number of revolutions to complete The machine beeps for 1 minute or press the red button \"RST\" to end the beep and return to thesetting status;

7. If you perform the same action, you can directly press the green button; otherwise, you must reset the number of revolutions and press the green button to start running;

8. At the end of the test, record the number of revolutions.
