QTX type elastic film tester (according to the national standard GB1731 - 93)
Determination of flexibility of paint film.
The paint film is coated on a metal plate, bent on a shaft rod of different diameters (mm) to determine the flexibility of the paint film. When the determination was carried out at 22 + 1 C, the relative temperature was not more than 70%.
1, equipment and equipment:
(1) the elastic film tester (Figure) consists of seven different diameter thickness of steel rod shaft, fixed on the base frame, the seat frame by a screw nail in the test stand on the edge of the table.
The size of each shaft bar is as follows:
Each shaft rod length 50 mm
Shaft rod 1 diameter 15 mm
Shaft rod 2 diameter 10 mm
Shaft rod 3 diameter 5 mm
Shaft rod 4 diameter 4 mm
The shaft rod 5 section 3*10 mm, the curvature radius of 1.5 mm
The shaft rod 6 section 2*10 mm, the curvature radius of 1 mm
The shaft rod 7 section 1*10 mm, the curvature radius of 0.5 mm
(2): the plate thickness of 0.2~0.3 mm, 20*100~150 mm in size.
2, operation and use of steps:
Use sand cloth or emery paper No. 0 polished iron, and loose perfume wipe, in the plate in the sample preparation method, or by the sample standard products, coated with paint.
If the product standard allows, can only iron loose perfume wipe, do not have to be polished, the film after drying, or according to the provisions of the product standard time, shaft model will be pressed to the 15 mm diameter 1, film upward, practicing Mandrel Bend 180 degrees, 90 degrees around the bending time 2~3 seconds.
If the paint film in the bending with four times the magnifying glass observation, no cracks and peeling phenomenon, that is, in the order of 10, 5, 4, 2, 1 mm of the various bars on the bending and observation. In the course of the experiment, the 4 times magnifying glass was used to observe the crack and spalling of the film, and the minimum diameter of the shaft rod is flexible or elastic.
General determination, you can directly in the product standard of the shaft rod bending, determination is qualified. The flexibility or elasticity of the film can be expressed by the MM number of the diameter of the shaft.
For example: (1) when the last flexibility with a 10 mm diameter shaft rod bending when no change is bent in a shaft diameter of 15 mm, no change, and 5 mm in diameter of the shaft rod is a bending damage cracking or peeling film. Here, 10 mm is the smallest diameter that is passed.
(2) the flexibility of the 1 mm diameter shaft rod bending no change, that is, all of the shaft on the bending of the film are not damaged.
