Taber Abrasion Tester test operation method

Taber Abrasion Tester test operation method

How does the Taber type abrasion tester perform the friction test?

 

From the outside, it is not very obvious, but the equipment is actually used to test the abrasion resistance of leather and plastic, fabric, floor tiles, and plywood by rotating and rubbing different types of friction wheels on the specimen (wheel numbers include H18, H22, CS10, CS17, CS32, CS33).

 

It can be seen that the Taber type abrasion tester relies mainly on rotary grinding, so that it is used to test the abrasion resistance of leather and plastic materials by using different types of friction wheels to rotate on the sample through the test disc. This requires us to choose the set of weights applicable to the standard. The abrasion index has a formula which is: weight of abrasion loss / number of test rotations * 1000

The results of the test are used to identify the properties of the test material and to check the weight loss on the outer surface of the sample, if there is mechanical damage.

 

The specific operation of the Taber type abrasion tester is as follows 13 points.

 

1. It is necessary to assemble the grinding wheel (abrasive wheel) required for the sample material before the test according to the relevant test standards for the test material. (Note: the tester will prepare additional fine sandpaper)

 

2. This step can be cut the standard test piece, and then to be attached to the back of the test piece with double-sided tape (the other side should also be attached to Oh), double-sided tape to remove the paper, weigh the test piece and record the weight, bear paw record to four decimal places.

 

3. Before opening the test you need to confirm that the power supply voltage is AC220V, frequency of 50HZ.

 

4. Before the test lift the test arm of the equipment, and then start the power supply to try to run, we can check from here whether the machine is running properly, and then lift the test arm and vacuum arm, remove the test piece fixing nut and spacer (ring), and then use a wrench to loosen the fixing screw of the fixing ring and pick up the fixing ring that is to complete this step.

 

5. Next step five, Azhong suggests cutting the prepared fine sandpaper into the model of the test piece in advance, then just put the center hole on the screw and then cover the spacer, and then use our nut to fix the fine sandpaper on the disc.
