QBY Paint Coating Pendulum Hardness Tester
1、 Overview of QBY Paint Coating Pendulum Hardness Tester Equipment:
The pendulum hardness tester is a conventional instrument used in the laboratory to measure the hardness of paint film coatings. Its working principle is: the softer the coating surface in contact with the fulcrum of a swinging rod that swings at a certain period, the faster the attenuation of the swinging amplitude of the swinging rod; On the contrary, the slower the attenuation. Due to the differences in structure, weight, size, swing period, and swing amplitude among various swing rods, as well as the complex elastic and viscoelastic changes under the interaction between the swing rod and the coating, an effective conversion relationship cannot be established between the measurement results of various swing rods. Therefore, when measuring the hardness of coating swing rods in various product standards, it will be indicated that only one type of swing rod is used.
2、 Technical parameters of QBY paint film coating swing rod hardness tester:
1. Power supply: AC220V 50Hz or 60Hz
2. Applicable pendulum types: Konig pendulum and Persoz pendulum
3. Dimensions: 380 × 300 × 700mm (length × width × height)
4. Host weight: kg
3、 Technical specifications of QBY paint film coating swing rod hardness tester:
The Konig pendulum has a triangular frame structure, while the Persoz pendulum has a square frame structure. The main technical indicators for the determination of two types of swing rods are shown in the following table:
Swing rod model: Konig pendulum Persoz pendulum
Starting and ending swing angle: 6 °~3 ° 12 °~4 °
Swing cycle: 1.4sec1sec
Swing rod mass: 200g 500g
Steel ball diameter: 5mm 8mm
Swing time on flat glass: 250 ± 10sec ≥ 420sec
Swing frequency on flat glass: 172-185 ≥ 420
Note: The ISO 1522 standard for the swing time of Persoz on flat glass is 430 ± 10sec.
4、 Industry standard for QBY paint film coating swing rod hardness tester:
The pendulum rod hardness tester is designed and manufactured based on the A method in the national standard GB/T 1730-2007, which is equivalent to the international standard ISO 1522-1998 "Paint and Varnish Pendulum Damping Test". The corresponding American Society for Testing and Materials standard is ASTM D4366-95. The BY-I type pendulum hardness tester is suitable for Konig pendulum (K pendulum) and Persoz pendulum (P pendulum). Therefore, the instrument has three configurations: pendulum hardness tester (with K-pendulum), pendulum hardness tester (with P-pendulum), and pendulum hardness tester (with K-pendulum and P-pendulum). Please confirm when ordering.
In most cases, the measurement time of Konig pendulum is close to half of that of Persoz pendulum, indicating that the resolution of Persoz pendulum is superior to Konig pendulum; However, the Persoz swing rod is prone to slipping on hard and slippery coating surfaces, which affects the actual measurement accuracy. It is generally believed that the Konig pendulum is suitable for testing harder coatings, while the Persoz pendulum is suitable for testing softer coatings.
The swing rod hardness tester is used in the testing process of chemical raw materials. Before use, users should establish appropriate safety and hygiene protection measures in accordance with relevant safety regulations and determine rules and regulations. The safety issues related to contact with chemical raw materials should be established by the user and are not within the scope of this manual.
