Тестер гибкости лакокрасочной пленки QTX

Обзор:
According to the national standard GB1731, the flexibility of paint film was determined. The flexibility of the paint film is indicated by the diameter of the small shaft rod which does not cause damage to the paint film.

Структура:
It consists of seven steel shaft rods of different thickness and diameter. Fixed on the seat frame, the seat frame can be fixed on the table side of the test bench with screws. The dimensions of each shaft rod are as follows:
Rod length: 50мм
Shaft rod 1: Diameter Φ15±0.05mm
Shaft rod 2: Diameter Φ10±0.05mm
Shaft rod 3: Diameter Φ5±0.05mm
Shaft rod 4: Diameter Φ4±0.05mm
Shaft rod 5:10 mm×30.1mm, curvature radius 1.5±0.1mm
Shaft rod 6:10 mm×20.1mm, curvature radius 1 ±0,1 мм
Shaft rod 7:10 mm×10.1mm, curvature radius 0.5±0.1mm
The verticality of each shaft rod and the mounting plane after the assembly of the flexibility tester
Tolerance is not greater than 0.1mm.

Операция:
1, the measurement should be carried out at 23 ° C ±2 ° C, relative humidity is not greater than 70% условия.
2, the test plate should be flat, without any visible cracks and wrinkles.
Размер: 120mm×25mm×0.2 ~ 0.3mm tinplate.
3. Use both hands to put the paint film of the test board up, firmly press on the specified diameter of the shaft rod, and bend the test plate around the shaft rod within 2 к 3 seconds using the strength of the two thumbs. After bending, the two thumbs should be symmetrical to the center line of the shaft rod.
4. After bending, observe the paint film with a 4x magnifying glass. Check whether the paint film has damage phenomena such as webs, cracks and spalling.
5, in the test process, should be sequentially from large to small on each shaft rod to do not cause damage to the small shaft rod diameter indicates the flexibility or elasticity of the paint film index.
