Overview
QHD pendulum damping tester is a professional test instrument designed by JINGKELIAN according to ISO1522 and ZBN7 2020-86 standards, which is used to determine the paint film Hardness of Paints, varnish and other related products. The instrument is equipped with Koenig pendulum and Platinum Saz pendulum with two different total mass pendulum bars, 200 +/- 0.2g and 500 +/- 0.1g respectively. The main structure includes instrument seat, pendulum, technical device and instrument cover.
Features
1. Equipped with Koenig pendulum and Platz pendulum with two different masses of pendulum
2. Koenig swing rod mass 200 +/- 0.2g, swing period 1.4 +/- 0.02s
3. Platinum saz swing rod mass 500g, swing period 1 +/- 0.001S
4. Using photoelectric timing technology
5. Equipped with horizontal adjustment device to ensure Test accuracy
6. Meet ISO1522 and ZBN7 2020-86 standards
Principle
Film Hardness is determined by the damping time, expressed in seconds, of the damping of the swing on the film when the swing rod touching the film surface swings at a certain period. The softer the surface, the faster the swing decays, and vice versa. There is no conversion relationship between the results of the Koenig pendulum and the Platinsaz pendulum due to differences in structure, mass, size and period, because the interaction between the swing rod and the coating also depends on the complex resilience and viscosity properties of the coating.
Applications
Paints, varnish and other related products - Determination of film Hardness
Standards
ISO1522、ZBN72020-86
Steps
1. Install the components of the plexiglass cover
2. Adjust the level Adjust the foot to ensure the level of the instrument
3. Choose the appropriate pendulum (Koenig pendulum or Platz pendulum)
4. Connect the photoelectric signal cable and the shutter cable
5. Use the starter handle to start the swing lever
6. Observe the swing change through the ruler
7. Timer automatically records damping time
8. Use the pallet control handle to operate
Notice
• There is no conversion relationship between the test results of the Koenig pendulum and the Platz pendulum
• In the product standard, only one swing rod is required to determine the damping time of a certain paint film
• The platinum saz pendulum needs to be customized, not standard.
• Instrument level must be ensured before testing
• The swing period and parameters of different swing rods are different
• Plexiglass covers need to be correctly installed with all components
