The Permanent Compression Rubber Tester Has A Cylinder Diameter Of 10±0.2mm.

Rubber permanent compression twist test machine JD-3126

product manual:

This machine is suitable for testing the test method of constant deformation compression set characteristics of vulcanized rubber. In this test, the vulcanized rubber sample is compressed to a specified height, and the compression set rate of the sample is determined after a certain temperature and time, or after being infiltrated by the medium.

The compression ratio can be based on the hardness of the sample (Shaoer A type selection)

The compression ratio of 50 or less can be selected as 40%;

The hardness can be 30% at a compression ratio of 50 to 75;

A hardness of 75 or more can be used for a compression ratio of 20%.

The main function:

Take the standard test piece, sandwich it between the flat plates of the device, rotate it with a screw, compress it to a certain ratio, and put it into the oven at a certain temperature. After the specified time, take it out, remove the test piece, and cool it for 30 minutes. Its thickness is calculated by the formula.

Test fixture:

The compression surface is required to be flat and its finish is not less than 7

The compression plate should not be deformed during the test. It is recommended to use steel plate with a length of about 75mm, a width of about 50mm and a thickness of about 10mm.

The height of the limiter is 8±0.02 mm, 7±0.02 mm, and 6±0.02 mm, respectively.

The incubator should have a continuous air blowing device, and the test temperature in the box is uniform. The temperature fluctuation range of the test area in the incubator is ±1 °C below 100 °C and ±2 °C from 100 to 200 °C.

.

Sample:

The sample is a cylinder with a diameter of 10 ± 0.2 mm and a height of 10 ± 0.2 mm.

The sample is vulcanized with a model whose surface should be flat and perpendicular to each other and parallel

test results:

The compression set rate K (%) is calculated as follows:

K= ×100

formula

Ho-sampl

e height before compression, mm;

H1-limiter height, mm;

H2-sample height after compression, mm.

After the test, the sample broke and the test data was invalidated.

The number of samples representing the performance of each sample shall not be less than three, and the arithmetic mean shall be taken. The allowable deviation is: the compression permanent deformation value is less than 10%, the allowable absolute deviation is ±1%, and the compression permanent deformation value is greater than 10 For %, take the relative deviation of ±10%. The number of samples after the selection shall not be less than 60% of the original sample.
