Project Description

DIN abrasion tester

Rotary Drum Abrasion Tester China Manufacturer

DIN abrasion tester is used to determine the wear resistance of vulcanized rubber, elastomer or thermoplastic subjected to wear by abrasive action using a rotating cylindrical drum device. A cylindrical rubber test piece slides over an abrasive sheet of the specified abrasive grade under specified pressure over a given distance during the whole testing process.

Din abrasion test is used for comparative testing, quality control, specification compliance testing, referee purposes, research and development work, etc. It is one of the most commonly used rubber testing instruments.

This Amade DIN abrader is suitable for the abrasion test of elastic materials, rubber, tires, conveyor belts, conveyor belts, shoe soles, soft synthetic leather, leather and other materials. It has the characteristics of high efficiency, good reproducibility and easy operation.

Test Principle

A cylindrical rubber test piece is fixed to the sample holder at the end of the cantilever beam. The operator puts down the swivel arm to ensure that the test piece is in utter contact with the abrasive sheet attached to the surface of a rotating cylindrical drum under the specified force. The loss in mass of the test piece is determined after it is traversed at a constant speed through a defined abrasion distance across the abrasive sheet.

After the mass loss of the test piece is measured, the volume loss can be calculated from the density of the material used for the test piece. The volume loss of the test piece is compared to that of a reference compound tested under the same conditions.

The wear resistance is expressed either as a relative volume loss compared to an abrasive sheet calibrated using a standard reference compound or as an abrasion resistance index compared to a reference compound. For volume loss, a smaller number indicates better wear resistance. while for the abrasive resistance index, a smaller number indicates lower abrasion resistance.

Features

  • The housing is made of precision steel and treated by anti-corrosion and anti-rust processes.
  • This rubber abrasion tester is mainly composed of a laterally moveable test piece holder and a rotatable drum to which the abrasion sheet is attached.
  • The abrasive sheet is attached to a rotating cylindrical rotating drum against which the test piece is held and across which it traverses with the help of the double-sided adhesive tape.
  • The swivel arm and test piece holder are free from vibration during the test.
  • The test sample is placed against the cylindrical drum with a vertical force of 10 N getting by adding weights to the top of the test sample gripper.
  • This DIN abrader is applicable to the non-rotating specimen and the revolving specimens.
  • The suction device is optional If required by customers.

Din Abrasion Test Procedure in Brief Introduction

  1. Weigh the test piece to the nearest 1 mg.
  2. Secure the specimen in the test piece holder, ensuring a length of 2mm±0.2mm protrudes from the opening.
  3. Press the test piece against the cylindrical drum under a perpendicular force of 10N.
  4. Start the machine to allow the test piece to slide over the drum by the lateral move from the starting point automatically(Turn on the suction If it is available), checking to make sure there is no vibration on the interface between the sample and abrasive sheet.
  5. Stop the test run once it reaches the specified abrasion distance.
  6. Remove the test piece and reweigh the test piece and record the value.
  7. Carry out all test runs on the same rubber consecutively.

The above is just a reference. Please strictly follow the procedure of the applied standard to carry out the test when you get this testing machine.
