AVU Überprüfungseinheit für Haftfestigkeitsmessgeräte

Die Elcometer AVU wurde entwickelt, um Anwendern von Abreiß-Haftfestigkeitsprüfgeräten zu ermöglichen, die Genauigkeit ihrer Geräte zu bestätigen.

Aufgrund ihrer robusten Bauweise ist die Elcometer AVU sowohl für den Einsatz im Feld als auch im Labor geeignet, wo sie Anwendern die Überprüfung bzw.Selbstzertifizierung ihrer Abreißtestgeräte ermöglicht.

Zur Prüfung der Elcometer 106-, Elcometer 506- und Elcometer 510 Haftfestigkeitsprüfgeräte ist eine Reihe von Stempeladaptern erhältlich. Adapter zur Überprüfung der Prüfgeräte anderer Hersteller sind ebenfalls erhältlich.

Bringen Sie den geeigneten Stempeladapter an der AVU an, schließen Sie Ihr Haftfestigkeitsprüfgerät an, bauen Sie Druck auf und vergleichen Sie die Messwertanzeige des Haftfestigkeitsprüfgeräts mit der AVU-Anzeige.

Das Gerät bietet unter anderem die folgenden Funktionsmerkmale:

  • Maximalwert- und Echtzeit-Messwertanzeige
  • Umschaltbare Maßeinheiten, MPa / psi
  • Displaybeleuchtung
  • Abschaltautomatik

Die Elcometer AVU ist wahlweise mit einem Prüfzertifikat oder einem vollständigen Kalibrierzertifikat erhältlich. Für die Selbstzertifizierung geeignet.

1. An Introduction to Pull-Off Adhesion on Coated Surfaces

Adhesion testers are used to test how well a coating has adhered to a surface, as poor adhesion can lead to premature coating failures. The coating inspector has essentially three main methods to choose from - cross hatch, push off, and the most common, the pull-off adhesion test.

2. Selecting the Dolly Diameter and Gauge

When it comes to selecting the dolly diameter and adhesion gauge type to use for a pull-off adhesion test; factors such as the substrate material, the substrate shape, and the expected coating strength will affect the dolly or gauge the user chooses.

3. Selecting the most Appropriate Position for an Adhesion Test
3. Selecting the most Appropriate Position for an Adhesion Test

When preparing a pull-off adhesion test, whilst the actual location and the number of pulls is typically defined by the test method or procedure that’s being followed, the actual positioning of the dolly is vital, as poor positions can result in low pull-off values or invalid tests.

5. To Cut or Not to Cut?

Should the coating around a dolly be cut, or left uncut prior to a pull-off adhesion test; and whose decision is it to make?

6. The Pull-Off Test
6. The Pull-Off Test

Once the glue between a properly prepared dolly or pull stub and a properly prepared coating has fully cured, the pull-off adhesion test can be undertaken using the adhesion tester of choice.

7. Assessing the Result; Glue, Adhesive and Cohesive Failures

Once the pull-off adhesion test has been completed the tensile pull-off force, whether the coating was coat or not, the dolly size and gauge type, and the failure mode of the coating are all recorded; with the nature of the failure usually recorded as an estimated percentage to the nearest 10%.

 8. Measuring the Pull-Off Adhesion of Coatings on Concrete

Testing coating adhesion on concrete substrates using a pull-off adhesion gauge is similar to testing coatings on metal substrates. However, there are a number of differences in the test procedures and equipment used.
