Overview
Tiandi Spark XH-M (50mm) Pull-out Adhesion Tester is a Portable instrument for the measurement of adhesion of metal, concrete and Miscellaneous coatings. Its self-positioning feature revolutionizes the adhesion Measurement mode. The coating of a certain diameter on the surface of the tested substrate is separated by the hydraulic system to measure adhesion. The multi-function digital display shows the result in MPa or KN units. The technology is reliable and the performance is stable.
Features
1. Portable handheld instrument, can be used in any place without external power supply, can be used in both laboratory and field
2. Large and easy-to-read LCD digital display
3. Press the button to select the kit size, Measurement unit and storage data, and automatically calculate the result according to the kit size
4. Portable instrument case with alloy and stainless steel body, rainproof, dustproof and impact-proof
5. High quality hydraulic pump can be applied to any occasion, quality assurance for three years
6. Pressure and display system are standard Force Gauge calibrated, accuracy control within +/- 1% (full scale)
7. Self-positioning kit, has no effect on measurement results on smooth and rough surfaces
8. High-grade industrial pressure sensor to ensure accuracy
9. Optional 10mm, 14mm, 20mm and 50mm kits
10. LCD liquid crystal display, MPa or KN unit can be selected by pressing the button
Principle
The instrument uses the hydraulic system to make a certain diameter coating on the surface of the tested substrate to measure coating adhesion. The multi-function digital display screen of the tester shows the size of adhesion, which is displayed in MPa or KN.
Standards
ISO 4624 "Pull-off test for coating and varnish adhesion", ASTM D 4541 "Portable adhesion meter standard test method for measurement of coating Peel Strength", ASTM D7234 "Standard test method for coating disbonding adhesive strength on concrete", GB/T 5210-2006 "Paints and varnish adhesion test"
Steps
1. Prepare the kit, sanding the coating of the pre-stick kit with a grinding pad, clean the oil stains on the surface of the kit and coating with a suitable solvent, and wait for drying
2. Open the two-component glue and mix it in a 1:1 ratio, spread it thinly and evenly on the bottom end of the drawing kit, press hard on the test surface, wipe the overflowing glue, and wait for the glue to be fully cured for about 24 hours
3. Counterclockwise swirl/spin right swirl/spin screw plug until swirl/spin cannot be done, press the pressurized handle to the bottom, press the snap ring pull ring to the bottom, lift the snap ring on the kit and make sure it is fastened
4. Press the first green button at the bottom of the display screen to turn on the power supply, and press the third button to select the pull-out kit size.
5. Press the KN/MPa key to select the test unit
6. Press the switch button to return to zero, swirl/spin the right swirl/spin valve clockwise to the bottom, slowly press the handle until the pull kit from the coating peeling, read the display fixed reading
Notice
• The instrument does not have a OK button. When selecting the unit or kit size, as long as what is displayed on the screen is required.
• When pressing the handle, slowly cycle up and down, and carefully control the pressing speed when feeling labored. The slower the better.
• Judging the coating adhesion grade should be based on the measurement results and the peeling phenomenon at the bottom of the peeling kit. More information can be obtained by observing the peeling phenomenon in the test area
