Sponge Compression Permanent Deformation Tester (Including Oven), With 75mm Steel Plate
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)
40% compression ratio below 50
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 compression surface is required to be flat and its finish is not less than 7u.
u -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.
u -The height of the limiter is 8±0.02mm, 7±0.02mm, and 6±0.02mm, respectively.
u -The constant temperature box should have a continuous air blowing device, and the test temperature in the box is even. 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.
u -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, and its surface should be flat and perpendicular to each other, parallel to u
u -Compression set rate K (%) is calculated as follows:
In the middle
Ho-sample height before compression, mm; u
H1-limiter height, mm; u
H2-sample height after compression, mm.u
After the test, the sample broke and the test data was invalidated. u
u -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: if the compression set value is less than 10%, the allowable absolute deviation is ±1%, and the compression set value is greater than For 10%, the allowable relative deviation is ±10%. The number of samples after the selection shall not be less than 60% of the original sample.
