Product introduction

taber wear tester is suitable for testing the abrasion resistance of fabric, paper, paint, plywood, leather, floor tiles, glass, natural rubber and other materials. Taber Abrasive Testing Machine Taber Abrasive Testing Machine places a rotating sample against a pair of abrasive wheels and applies a specified load. When the sample rotates, it drives the abrasive wheel to wear the sample.

Scope of application:

The taber wear tester is mainly used to test the wear resistance of leather and plastic materials. The rotary grinding method uses various types of friction wheels to rotate and rub the sample to test the wear resistance of leather and plastic materials.

Taber Abrasion Tester Method Operating Instructions Test Preparation:

1. The VOrm of the test piece is the diameter (outer diameter) 110mm circular shape and a hole with a diameter (inner diameter) of 9mm in the center, take the sample.

2. Fix the sample on the test turntable, select the required test weight and install it, and make sure that the test grinding wheel does not come into contact with the sample mount during the test.

3.Taber Wear Tester Test Steps:

A. Prepare the grinding wheel (abrasive wheel) required for the material of the test piece before the test, and the grinding wheel used for the dough is CS No. 17, the grinding wheel used for the embossed leather test piece is H-22, and a few pieces of fine sandpaper are prepared for the grinding wheel verification.

B. Cut the standard method (outer diameter 110mm, inner diameter 9mm, thickness 3mm), stick one side of the double-sided tape on the back of the test piece, remove the sticker on the other side, weigh the test piece andwrite it down. (Four digits below the decimal point)

C . Check whether the power supply is OK and if it is in compliance, connect the power supply.

D. Raise the arm of the test handle, then activate the power and try to run first and check whether the machine works normally.

E. Lift the test arm and suction arm, remove the test piece butterfly cap attachment and \" gasket (ring)\", unscrew the fixing ring with a wrench and pick up the fixing ring.

F. Cut the prepared fine sand into the test piece model, put the center hole on the screw, put the gasket, fix the nut with the test piece and attach the fine sandpaper to the disc.

G. Insert the fixing ring, flatten the sandpaper and tighten the fixing ring fixing screw with a wrench.

H. Select the grinding wheel (CS-17 or H-22) according to the test standard. Loosen and remove the grinding wheel fixing nut, install the grinding wheelpwheel and then tighten it to fix it.

I .Required weight:

Dough skin-CS-17, bar weight 250g+weight weight 750g=1000g

Embossed nut skin-H-22, bar weight 250g+weight weight 250g= 500g

J. Set the number of test rotations to 50 times, put down the test arm and suction arm, turn on the power switch and suction switch, adjust the air volume, and turn on the motor switch to start operation. For the H-22 grinding wheel, grind 50 times with the fine grinding wheel before each operation of the test piece abrasion test, and for the CS-17 grinding wheel, grind 50 times with the grinding wheel only for the first wear of the test piece with a new grinding wheel.

K. After sanding with sandpaper 50 times, turn off the power, remove the sandpaper following the reverse steps of E, F, and G, and insert the test piece following the steps of E, F, and G.

L. Set the number of test rotations to 1000 times, stick the sand on the grinding sclift with a plastic adhesive, check whether the double-sided tape of the test piece is stable, stick the test piece on the test disc, and then repeat step J

M. When the set number of tests is reached, the power will be turned off automatically .

N. Taber Abrasion Tester Taber Abrasion Tester Method Operating Instructions After stopping the machine, use a small brush to remove the sand on the leather surface, and remove the test piece together with the double-sided tape, weigh it with a precision balance, count to four decimal places, and record it , and calculate the test value according to the formula.

Test Evaluation Criteria:

There are several ways to evaluate the results of a Taber Abrasion Tester abrasion test. Users should choose the appropriate test result evaluation method according to the characteristics of the material itself. For general evaluation methods of sanding results, see "Taber 5135/5155 sanding test machine tesresult evaluation method".
