Five Advantages Of Products

  • Keep the Martindale wear-resistant instrument clean at all times. Wipe the cylindrical shaft with cotton cloth before and after each experiment to keep it clean.
  • If it is not used for a long time, please remove the test pressure plate and spray anti-rust oil.
  • Lubricate the gear parts monthly.
  • The turntable in the middle of the Martindale wear tester is made of plastic, and the screws on the fixing holes are easily damaged. Therefore, when changing between the wear resistance test and the pilling test, care should be taken to protect the screws of the turntable.
  • Use Martindale wear tester to test, the curve drawn by the friction head is the standard Li Sharu curve, guide plate, friction.

Product Details

The following is the Martindale wear tester:

 

Basic parameters of Martindale wear tester: 

 

Product Name: Martindale Wear Tester

Type Number: Custom

Scope of application: Test measurement of abrasion resistance and pilling degree of knitted fabrics, woolen fabrics, artificial leather, synthetic leather, etc. under pressure

Heavy Amount: 100KG

Size (mm): 520*450*420

Outer axis: 47.5±2.5r/min

Inner axis: 44.5±2.4r/min

Test weight: 4N/6

Compliant with standards: Tests for the degree of pilling of fabrics such as GB/T4802.1-1997, ASTM D4970, ISO12945-2; Tests for abrasion resistance of fabrics such as GB/T13775, ASTM D4966, ISO12947

 

The following is the operation method of Martindale Abrasion Tester (standard operating procedure for floor surface resistance to micro-scratches):

 

1. Cut the floor sample into 14cm*14cm (5.5*5.5 inches). If the floor width is less than 5.5 inches, please be careful not to put the two floors together, take the natural width.

2. Use double-sided tape to stick the samples on the sample table, and place the samples in a row. The machine direction and the length of the floor are level with the direction of the console.

3. Use double-sided tape to put a medium scouring pad (3.5 inches in diameter) on the wipe board, and place the 4N load on the wipe board.

4. Turn on the switch on the left side of the machine.

5. Use the display panel on the right, enter 160 revolutions, and then click OK to start the test.

6. Make sure that the sample does not move during the test.

7. After the test is completed, take out the sample and throw away the scouring pad.

8. Wipe the surface of the sample with a dust-proof cloth.

9. Evaluate the degree of scratching on the surface of the sample with the arm extended to the farthest distance and at different angles.

 

The following is the operation method of Martindale Wear Tester (standard operating procedure for floor gloss retention):

 

1. Cut the floor sample into 14cm*14cm (5.5*5.5 inches). If the floor width is less than 5.5 inches, please be careful not to put the two floors together, take the natural width. Wipe the surface of the sample clean with a dust-proof cloth.

2. Use a photometer with a geometric angle of 60 degrees to test the initial luminosity values of two points on the sample, 1-2 inches from the edge of the sample. The direction of the light meter should be parallel to the direction of the floor texture or the length direction.

3. Use double-sided tape to stick the sample on the sample table, arrange the samples in a row, and the machine direction and the length of the floor are level with the direction of the operating table.

4. Use double-sided tape to put a medium scouring pad (3.5 inches in diameter) on the wipe board, and put the 6N load on the wipe board.

5. Turn on the switch located on the machine.

6. Enter 80 revolutions, then confirm and start the test.

7. Make sure that the sample does not move during the test.

8. After the test is completed, take out the sample and throw away the used scouring pad.

9. Wipe the surface of the sample with a dust-proof cloth.

10. Re-measure the photometric value of the sample at the same position according to 2.2.

11. Calculate the luminosity loss according to the following formula:% luminosity loss=(initial average luminosity value -===final average luminosity value)*100%

 

Determine the gloss retention level based on the following data:

 

% Luminosity loss: ≤10 loss; gloss retention level: 1

% Luminosity loss: 11-30; gloss retention level: 2

% Luminosity loss: 31-50; gloss retention level: 3

% Luminosity loss: 51-70; gloss retention level: 4

% Luminosity loss: ≥71; gloss retention grade: 5

 

Maintenance of Martindale Wear Tester:

 

1. Keep the Martindale wear-resistant instrument clean at all times. Wipe the cylindrical shaft with cotton cloth before and after each experiment to keep it clean.

2. If it is not used for a long time, please remove the test pressure plate and spray anti-rust oil.

3. Lubricate the gear parts monthly.

4. The turntable in the middle of the Martindale wear tester is made of plastic, and the screws on the fixing holes are easily damaged. Therefore, when changing between the wear resistance test and the pilling test, care should be taken to protect the screws of the turntable.

5. Use Martindale wear tester to test, the curve drawn by the friction head is the standard Li Sharu curve, guide plate, friction.
