TIANDIXINGHUO XH-M Adhesion Tester Pull Method/Pull Method 10mm

XH-M(10mm)

Adhesion Tester

Manual, force value Measurement range 0~10KN, range 0~127.38MPa, kit diameter 10mm, resolution 0.001KN/0.001MPa, piston stroke 10mm, accuracy ≤ +/- 1% F.S

    The XH-M pull-off adhesion Tester can measure the adhesion of metal, concrete and other material coatings - the self-positioning feature has brought new changes to the way of adhesion measurement. The Principle of the instrument is to use the hydraulic system to separate the coating with a certain diameter on the surface of the tested substrate to measure the adhesion of the coating. The multifunctional digital display of the Tester displays the adhesion, which is displayed in MPa or KN. The product is designed and manufactured according to relevant international and national standards, with reliable technology and stable performance.

Features

1. Portable handheld instrument, can be used in any place, no external power supply is needed-it can be used in both laboratory and field.

2. Large and easy-to-read LCD digital display

3. Press the button to select the spindle size, measurement unit and storage data, and automatically calculate the result according to the spindle size.

4. Portable instrument case and alloy and stainless steel main body, rainproof, dustproof and impactproof.

5. The high-quality hydraulic pump can be used in any occasion, with a three-year warranty.

6. The pressure and display system have been calibrated by a standard dynamometer, and the accuracy is controlled within ±1% (full scale).

7. The self-positioning spindle has no effect on the measurement results on smooth and rough surfaces.

8. High-grade industrial pressure sensor ensures accuracy.

9. 10mm, 14mm, 20mm and 50mm spindles are available.

10. LCD liquid crystal display, press the button to select MPa or KN unit.

Instructions

1. Prepare the spindle, and use a grinding pad to polish the coating of the pre-bonded spindle, and then use a suitable solvent to clean the spindle and the oil and other dirt on the surface of the coating to be measured, and wait for drying;

2. Open the two-component glue in the instrument, mix it at a ratio of 1:1 (mix as much as you use), spread it thinly and evenly on the bottom of the drawing spindle, and press the spindle firmly on the prepared test surface , apply pressure to squeeze out the excess glue, then wipe off the overflowing glue, and wait until the glue is fully cured (about 24 hours) before preparing for the adhesion test (if necessary, use the supplied cutting knife to cut around the spindle );

3. Pressure relief: Rotate the protruding rotary screw plug on the right side of the instrument counterclockwise until it cannot be rotated, and keep pressing the pressure handle to the bottom. In this state, press the pull ring on the clasp to the bottom. You can pull the snap ring, put the snap ring on the spindle, and pull it to ensure that it is tightly fastened;

4. Press the first green button below the display screen of the instrument to turn on the power; then press the third button (with a spindle graphic on it) to select the size of the drawing spindle (10, 14, 20, 50 optional), generally The spindle size of the standard configuration of the instrument is 20mm, so when the size is converted to 20mm, we can proceed to the next step----select the unit of the instrument test

5. There are two options for the unit of the instrument, MPa and KN. KN is the unit of force value. The unit of adhesion strength we often use is MPa. Press the KN/MPa key to convert the unit;

Note: The instrument does not have a confirmation key. When selecting the unit or the size of the spindle, as long as the unit or size being displayed on the screen is what we need.

6. Press the power button again to reset the instrument to zero, turn the rotary valve on the right to the bottom clockwise, and then slowly press the handle (the process of slowly lifting up and down in a cycle), and the frequency will be displayed at this time. The reading on the top is also slowly rising from 0.000. Gradually, we will feel a little hard. At this time, in order to get a more accurate result, we must carefully control the speed of pressing down (the slower the better), until the spindle is drawn from The coating falls off, and the fixed reading on the display at this time is the adhesion strength of the coating;

Note: The evaluation of the adhesion level of the coating is generally based on the measurement results (that is, the measured readings) and the shedding phenomenon at the bottom of the shedding spindle. Observing the shedding phenomenon in the test area will give information about the shedding and the different layers of the coating. More information on the adhesion and cohesion between them.
