Model LDN-II Cord Dynamic Adhesion Tester
|
|
LDN-II Cord Dynamic Adhesion Tester allows the cord to vulcanize in the rubber sample square with its 2 ends fixed by different weights at a pre-set temperature (temperature adjustable from room temperature to 100â??). During testing, the rubber sample will assume on a reciprocating movement along the extension of the cord with certain amplitude and frequency, and thereby generates a continuing dynamic shear at the interface between the cord and the rubber. With repeated deformation, the adhesiveness at the interface between the cord and rubber gradually decreases until reaching certain pre-set value. By measuring the time or numbers of deformation required for the cord and rubber to reach a certain adhesion level, the adhesive properties of the cord and rubber under dynamic conditions can be indicated.
