The QHD pendulum damping Tester is designed by JinKeLian according to the standards ISO1522 and ZBN72020-86 to measure the paint film hardness of paints, varnishes and other related products. The pendulums are 200+0.2g and 500+0.1g respectively. The main structure of QHD pendulum damping Tester includes instrument base, pendulum, technical device and instrument cover.
The hardness of the paint film is based on the damping time (expressed in s) of the swing attenuation on the paint film when the pendulum rod in contact with the surface of the paint film swings at a certain period . If the surface is softer, the swing decay will be faster, and vice versa. . Note that there is no conversion relationship between the test results of Konig and Persoz pendulums with different structures, masses, sizes, and periods, because of the interaction between the pendulum and the coating. The effect also depends on the complex elasticity and viscosity of the coating. Therefore, in the product standard to measure the damping time of a certain paint film, only one kind of pendulum is specified.
