Product Details
QHD type pendulum damping tester
Overview of QHD type pendulum damping tester:
Pendulum hardness testing is one of the internationally recognized methods for testing hardness in the paint industry, used to determine the hardness of dried coatings. It is designed according to GB/T1730-93 and ISO1522.
Support two stainless steel balls on the hardness tester of the swing rod on the dried coating and swing them at a certain period. If the coating surface is softer, the swing amplitude of the swing rod will decay faster (manifested as a shorter swing time from 6 ° to 3 °). On the contrary, the harder the coating surface, the slower the attenuation of the swing.
QHD type pendulum damping tester, also known as Konig single pendulum, hardness is expressed in terms of damping time, which is the product of the number of swings of the pendulum within a specified angle and the swing period.
Note: In order to obtain reliable test data, the test should be conducted under controlled temperature and humidity conditions without the influence of airflow, and the thickness of the coating and the material of the substrate can also affect the damping time
