Overview
The RONGJIDA FZ-10 coating adhesion tester is a Portable, one-piece structure designed pull-out adhesion testing instrument using an LCD screen. The instrument is specially developed and manufactured to detect the adhesion of metal, concrete and Miscellaneous coatings. It is suitable for Quality control or laboratory or on-site testing of construction units. No external power supply is required. It can automatically calculate and display the force value and strength results according to the size of the pull head.
Features
1. Portable integrated design, door-shaped structure.
2. Adjustable display mode, support for force value (KN) and intensity (MPa) display.
3. Equipped with a large LCD screen with lighting function, it is convenient for night operation.
4. Equipped with pressurization rate indication function, it is convenient to observe and adjust the pressurization process.
5. The size of the pull head, Measurement unit and storage data can be selected by pressing the button.
6. The results can be automatically calculated according to the size of the selected pulling head.
7. With peak hold function, it can store up to 500 test data.
8. Adopt 5-segment polyline numerical correction technology to ensure Measurement accuracy.
9. Built-in high-capacity lithium battery, no external power supply is required, suitable for laboratories and various field environments.
Principle
The instrument uses a manual drawing method to pull the puller of a specific size from the coating surface by applying a pulling force, and measures and records the maximum force required to destroy the coating adhesion. The internal system of the instrument automatically converts the measured force value into adhesion strength (MPa) according to the preset area of the puller head, which is visually displayed on the LCD screen.
Applications
Metal coating adhesion testing, concrete coating adhesion testing, Miscellaneous material coating adhesion testing, Quality control unit laboratory, construction unit site testing
Standards
GB/T 5210-2006、TB-T2965-2011
Steps
1. Select the appropriate drawing head size (such as 20mm or 50mm) according to the tested coating.
2. Measurement units and parameters are set through the instrument buttons.
3. Firmly paste or fix the pull-out head on the surface of the coating to be tested.
4. Manually operate the instrument, apply uniform pulling force to the puller, and observe the pressurization rate indication at the same time.
5. When the coating is pulled off, the instrument automatically maintains and displays the peak force value (KN) or the calculated adhesion strength (MPa).
6. Test data can be stored and history can be viewed through the display.
Notice
• Please ensure that the instrument is fully charged before use.
• Correctly select and install the puller according to the testing standards and requirements.
• Pay attention to keep the pressurization rate uniform during operation to obtain accurate data.
• Ensure that the drawing head adheres firmly to the coating surface to avoid peeling during testing.
• Regularly calibrate the instrument to ensure Measurement accuracy.
• Be careful not to exceed the 500 capacity limit when storing data.
• The instrument is a precision equipment, please handle it with care to avoid violent impact.
