Film mechanical performance testing instrument category summary
hardness
Pencil Hardness Tester
Use a pencil to test the hardness of coating scratches, and use it with pencils of different grades of hardness.
Shore Hardness Tester
It is widely used in the hardness determination of rubber and plastic, and can be divided into three types: A type, C type and D type.
Pendulum Hardness Tester
Used to determine the hardness of organic coatings, and the results are expressed as a percentage.
Scratch Tester
The strength, hardness, and adhesion of the coating are characterized by the penetration resistance of the paint film sample coating when it is scratched by a stylus.
Indentation Hardness Tester
Not only can it directly test the microhardness of the material, but also can directly test the fracture toughness and residual stress of the interface system between brittle materials and brittle coating film materials.
Adhesion
Paint film scratcher
A tool for measuring dry coating adhesion to a surface by making a series of coating incisions.
Circle method adhesion Tester
The rotating needle draws a series of circular rolling lines on the paint film, and then evaluates according to the completeness of the paint film within the scratches of the circular rolling lines. It is divided into 7 grades, and grade 1 is better.
Pull-off adhesion Tester
A detection instrument that peels the coating per unit area from the coated substrate.
roughness
Roughness Tester
Widely used in the detection of various metal and non-metal processing surfaces.
wear resistance
Abrasion testing machine
Put the material to be tested on the turntable, and the abrasive wheel presses against the material with a certain pressure to make it wear.
flexibility
flexibility Tester
A tool used to evaluate the flexibility of the paint film, the diameter represents the flexibility of the paint film, and the flexibility of the paint film is represented by the smallest shaft diameter that does not cause damage to the paint film during the test.
Bending test machine
Fix the sample on the fixture, and add a certain load test, check the breakage rate after a certain number of times, or until it is completely broken.
Cupping instrument
Used to test the cracking resistance and separation performance of the coating from the metal substrate at different deformation stages
Shock proof
Paint film impact Tester
It is used to drop a weight with a fixed mass on the test panel to observe the test condition of the paint film on the test panel.
