Taber Rotary Abraser Test Procedure معدات اختبار

Product introduction

The taber rotary abrasion tester is suitable for leather, fabric, paint, paper, floor tiles, plywood. of materials such as glass, plastic floor, natural rubber, etc., use a standard cutter to cut the sample, specify the type of sandpaper, load a certain weight to bear it, remove the test piece after the specified number of revolutions, and observe the condition of the test piece.

Applicable Standards:

QB/T2726-2005, ASTM D4060, ASTM D1175, D1044, DIN53754, 53799, 53109, 52347, ISO5470, GB/T4085.

Formula for calculating the wear index:

Weight loss due to wear/test revolutions*1000

10. Power supply: 1∮, AC220V, 50HZ.

Testing principle:

Taber wear-resistant testing machine mainly by the way of rotation grinding, use different kinds The friction wheel is rotated on the sample to test the wear resistance of leather and plastic materials. Select the default applicable weight set for material testingalproperties. Detect weight loss on the outer surface of the sample such as obvious mechanical damage.

Test steps:

1. Clamp off the sample

Place the cut sample on the test bench according to standard requirements.

Hold the sample flat, tighten the compression nut and gasket and tighten the sample retaining ring with an Allen wrench.

2. Clamp the wear wheel and weight

Install the pre-ground standard wear wheel for the balance arm inside and tighten the compression nut .

Clamp the corresponding weight or counterweight according to the required pressure.

In accordance with the specifications of the grinding wheels tested for different materials in the corresponding standards, install the grinding wheels with the corresponding specifications.

3. Start Turn on the power switch.

Suggest araf set number of laps on the counter.

Press the start button, the motor will spin the turntable.

Note:

1. When the grinding wheel is worn to the surface of the sticker or the grinding wheel is uneven, it should will be replaced.

2. Before measuring each sample, the grinding wheel should be cleaned with a brush.
