的详细介绍
一. Application
This Permanent Rubber Compression Deformation Tester is suitable for testing the test method for the constant deformation compression set characteristics of vulcanized rubber. In this test, the vulcanized rubber sample is compressed to a specified height, and after a certain temperature and time, or after being infiltrated by the medium, the compression set rate of the sample is measured.
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. The compression surface is required to be flat and the finish is not less than 7
B. 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.
C. The height of the limiter is 7.62 mm, 8.89 mm, 9.52 mm, and 10.16 mm, respectively.
D. The constant temperature box should have a continuous air blowing device, and the test temperature in the box is uniform. The temperature fluctuation range of the test zone in the incubator is ±1 °C below 100 °C and ±2 °C from 100 to 200 °C.
