What is the test of pulling?
The tension of adhesion, also called the Pull Off Painting Test, is a process used to determine how well the coating performs and links to a particular substrate such as concrete. This test is carried out by gluing the loading accessories known as Dolly or the stump to an epoxy coating. This load is then applied to a consistent measured pressure in an effort to interrupt the load on the load with the surface coating, breaks the coating with the substrate or breaks the surface of the substrate itself. Test tape. Creating a test should require a considerable amount of pressure to interrupt the binding of suitable substrate coatings. In the case of the strongest coatings, it is actually possible to break the substrate before bonding the coating disruption is disturbed. Creating testers are available in three styles: mechanical, pneumatic and hydraulic. This test device is designed to supply the vertical pull -out force required to perform an accurate test. For the most accurate result, the test should be furnishedImmaging this power to the plane, which is perpendicular to the test surface.
The adhesion of tester towing works by developing a controlled, measured power to Dolly. These loading luminaires are available in a number of sizes to allow the physical properties of different types of substrate and provide the ability to accurately determine the wider range of tensile forces. The pulling test ends when the weakest component of the system loses its bond with other components. This Includes system: Dolly, epoxy adhesive, surface coating and substrate.
If the dolly is pulled out of the surface coating without damaging the adhesion of the coating to the substrate, the measurement of the pressure required to perform the task is recorded as the strength of the surface coating. When the binding between the coating and the substrate is interrupted, this measurement is recorded as a point of adhesive failure. If the surface coating or failure of the substrate experience, this measurement is recorded as SOUa steep point of failure.
