About Abrasion Tester for Sole Leather
Abrasion Tester For Sole Leather
The Resistance To Abrasion Of Sole Leather May Be Determined With The Help Of A Drum Type Abrader (similar To Nbs Abrader).
In This Test, An Abrasive Cloth Strip Of A Specified Grit Is Fixed Over The Circumference Of A Drum, Which Is Rotated At A Specified Speed. The Test Specimen, In Shape Of A Rectangular Strip, Is Held On A Metallic Bar Located Above The Drum Such That Its Longer Axis Is Perpendicular To The Axis Of The Drum. When The Metallic Bar Is Pressed Against The Drum, The Test Specimen Gets Abraded. The Number Of Revolutions Needed To Produce A Depth Of Abrasion Of 2.5 Mm Is Determined And Compared Against That Needed To Produce A Depth Of Abrasion Of 2.5 Mm In A Standard Rubber Compound To Obtain The Abrasive Index Of The Leather Sample Under Test.

FAQs of Abrasion Tester for Sole Leather:
Q: How does the Abrasion Tester for Sole Leather operate?
A: The tester uses an abrasion drum, controlled manually or via a digital timer, to apply a controlled number of cycles to a leather specimen. After mounting a 70 x 25 mm specimen, the user sets the desired test parameters and initiates the cycle; the digital LED displays progress, and the machine automatically stops once the chosen cycles are complete.
Q: What types of sole leather can be tested with this machine?
A: This equipment is suitable for standard sole leather specimens that measure 70 x 25 mm. The robust abrasion drum meets the required hardness of 7075 Shore A, making it appropriate for most commercial sole leather testing applications.
Q: When is it advisable to calibrate or check the machine settings?
A: Regular calibration is recommended, especially before starting a new batch of tests or when the readings appear inconsistent. Checking the settings ensures that the accuracy of 0.1 mm and resolution of 0.01 mm are maintained for precise results.
Q: Where should the Abrasion Tester be installed?
A: The tester should be installed on a stable benchtop in a laboratory setting, preferably in an environment maintained at 23C (2C) with a relative humidity of 50%. Proper ventilation and power supply (230 V AC, 50 Hz) are also required.
Q: What is the process for conducting an abrasion resistance test?
A: Mount a single specimen onto the testing platform, configure the number of test cycles desired (up to 99,999 cycles), and select the appropriate control mode (manual or digital timer). Start the test using the push-button interface; the machine will automatically stop once the test is complete.
Q: How does using this abrasion tester benefit laboratories and manufacturers?
A: Utilizing this tester allows for precise, repeatable assessment of sole leather durability. Its semi-automatic operation saves time, improves accuracy, and supports compliance with quality standards, ultimately ensuring the production of reliable footwear products.
