JFL QHD pendulum damping Tester

Introduction

QHD pendulum damping Tester Specifications and uses

The QHD pendulum damping Tester is designed and manufactured according to the professional standard ZBN72020-86 and the international standard ISO1522-------1973.

This instrument is used for sampling tests of paints, varnishes and related products to determine the film hardness of paints, varnishes and related products.

Principle

The damping time of the swing attenuation of the swing rod on the paint film is expressed in seconds. The hardness of the paint film is based on the pendulum rod touching the paint film surface at a certain cycle. If the surface is softer, the swing decay will be faster, and vice versa. The slower the principle. It is worth noting that there is no conversion relationship between the test results of the Konig and Persoz pendulums with different structures, masses, sizes, and periods, because the pendulum and the coating The interaction between them 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 pendulum is specified.

Structure: QHD pendulum damping Tester is mainly divided into the following parts.

(1) Instrument base: used to support the test plate and swing rod, there is no vertical support rod on the base, and it is connected with a horizontal platform with a working plane.

(2) Pendulum: Konig or Persoz   

(3) A technical device that automatically records the number of required swing angles.

(4) Instrument cover
