GA-1173海绵重复压缩寿命试验机

描述

Sponge Compression Life Tester

概括
The Foam Repeated Compression Test Machine apply to test rate of permanent deformation of plastic foam material.After repeatedly compress specimen, check recovery level in stipulated, we can get permanent deformation rate, user can set test times and test machine will automatic stop after reach setting times.

原则
Put the specimen between two compression plates. Compress the specimen to 50% of its original thickness with the reciprocating compression speed of 60 times per minute till reaching 80000 次. Then the specimen is put aside for 30 minutes prior to measuring the thickness. The permanent deformation rate can then be calculated.
