Where can the Paint Adhesion Tester be used?

QFD Paint Film Adhesion Tester, also known as Paint Film Adhesion Tester, measures the paint film adhesion performance test by the circle track method. Technical characteristics: The completeness of the paint film within the scratch range of the circular rolling line is divided into seven grades. Evaluate the adhesion of the paint film to the substrate

Structural principle of QFD adhesion tester

The paint film adhesion tester is a desktop and is divided into four parts.

1. The main transmission part is composed of motor, toothed belt, toothed pulley, helical gear transmission and drawing head. The drawing head is composed of head screw, screw nut and eccentric head.

2. The workbench is composed of lead screw, half-open nut and test bench.

3. The base is composed of slide rails and electrical controls. Electrical control includes a piercing display circuit and a control motor circuit.

4. The stroke-limiting control device is composed of a stopper and a micro switch.

FAQ
QI read this, and the final judgment is still a little vague. There are 1-7 grades. How to define which grade it belongs to, and which grade is complete to what extent. I didn't explain it in detail.
A Lift the half nut (7), pull out the test bench (6), and change the needle. When it is found that scratch does not match the standard turning radius, the turning radius should be adjusted. The method is to loosen the bolts behind the pin plate (3) and the turning radius adjustment bolt (4). After moving the pin plate properly, tighten the above bolts in turn. If scratch is compared with the standard circular roller chart, if it still does not match, the turning radius should be readjusted until it is the same as the standard turning radius of 5.25 mm. When measuring, place the sample on the test bench (6), tighten the adjustment bolts (5), (8), and adjustment bolts (10) of the fixed sample, and move the lifting rod (2) backwards so that the tip of the rotating needle touches the paint film. If the bottom plate is not scratched, the weight should be added as appropriate. Shake the handle (11) evenly in a clockwise direction. Rotation speed should be 80-100 rpm, and the standard drawing length of the circular roller line scratch is 7.5 +/- 0.5 cm. Move the lifting rod (2) forward so that the chuck plate is lifted, loosen the relevant bolts (5), (8), (10) that fix the sample plate, remove the sample plate, remove the paint chips on the scratch with a paint brush, and check the scratch with a quadruple magnifying glass and grade. III. Rating method Take the upper side of the scratch on the sample as the inspection target, and mark seven parts such as 1, 2, 3, 4, 5, 6, and 7 in turn. Correspondingly divided into seven grades. Check the integrity of the paint film of each part in sequence. If more than 70% of the lattice of a certain part is intact, it is determined that the part is intact, otherwise it should be considered damaged. For example, part 1 paint film is intact and the adhesion is the best, which is set as first grade; part 1 paint film is damaged and part 2 is intact, followed by adhesion, which is set as second grade. And so on, seventh grade is the worst adhesion. The results are based on the same level of at least two templates.
QHow many needles does this go with?
A Comes with a box, about 150 sticks in it.
QHow much is this QFD Power?
A Frequency 50Hz, Capacitance 1.5uF.
QIf this QFD electric paint film adhesion tester needs a few more boxes of scratches, how much do you need to add?
A Yes, a box comes standard.
QIs the standard for QFD grading based on GB/T 1720?
A Yes!
QI need that Adhesion Tester that circles with a needle on the coating
A This one is it.
QWhich standard is this rating based on?
A The standard is GB/T 1720, and the standard test substrate is tinplate. There are no qualitative regulations on size and thickness. As long as it can be placed on the instrument, the thickness does not exceed 1mm.
