What are the sample size requirements for the Taber 5135 wear testing machine? This is the case

Product Introduction

What are the sample size requirements for the Taber 5135 Abrasion Tester? Taber 5135 is a grinding wheel testing machine (single grinding wheel), which evaluates the abrasion resistance of materials through the friction between the grinding wheel and the sample. Here, Shanghai Qianshi reminds everyone that in order to ensure that the wear resistance of the material can be objectively displayed, the requirements for the sample during the test are as follows:

Size Requirements

The pad width of the grinding wheel is 12.7 mm (0.5 in) and the distance from the center of the sample is 31.75 mm (1.25 in). The size of the sample is related to the material of the sample. For most hard samples, the sample size can be a square with a side length of 100 mm (4.0 in). For soft samples, it is best to make the sample round and asample retaining ring. If a sample pad is used, the sample should be 108 mm (4.25 in) in diameter. If a sample pad is not used, the sample diameter should be 135 mm (5.25 in.) so that the sample retaining ring can be clamped around the edge of the sample.

If the sample is smaller than the recommended size, 2 to 3 samples can be placed on the sample pad to meet the needs of the test. If the edges of the sample do not meet or if the thickness of the sample is different, the wear test results reflected on the edge will differ from the results of other parts of the sample.

Thickness Requirements

The standard sample thickness for the Taber 5135 abrasion tester is 0.25 in. (6.35 mm). For samples greater than 6.35 mm (0.25 in) and less than 12.7 mm (0.5 in) in thickness, the S-21 riser nut must be adjusted. Thicknesses greater than 12.7 mm (0.5 in.)require the use of an abrasive standard arm riser.

Taber Abraser can meet the needs of n-standard size test samples by selecting sample pads and sample disks. All sample trays have a ball valve and a dowel spring to hold the sample tray on the motor shaft. This device prevents the sample pan from vibrating during testing and allows easy removal of the sample pan for sample observation or cleaning of the mounting holes on the motor shaft.

Sample Pads Sample Pads (S-36 and S-36-1)

108 mm (4.25 in) diameter rigid Sample Pads coated on one side with pressure sensitive adhesive. When used for testing textiles and other soft samples, the sample can be placed firmly on the sample pad to prevent wrinkling. A test record sheet is printed on the back of the sample block for storing sample test information. There are 2 soort sample blocks, square (S-36) and round (S-36-1)

Sample Block Form Sample Block Form (S-37 and S-37-1)

Rigid sample with a diameter of 108 mm (4.25 in) The pads are coated on both sides with a pressure-sensitive adhesive covered with a protective paper that peels off before use. Thinner than the S-36 and S-36-1, the S-37 and S-37-1 are used for samples that do not slide on the turntable, especially samples that cannot be drilled in the center, such as glass and ceramics . There are 2 types of monster blocks, square (S-37) and round (S-37-1). The test record sheet is printed on the front and back of the test block to store the sample test information.
