Pancil Hardness เครื่องทดสอบการขูดขีดความแข็งผิวเคลือบ ITK-PEN-M001

Hand pencil hardness tester is also called scratch pencil hardness meter, hardness is an important physical properties of the lens, coating film, such as wear resistance, wear particle performance, friction resistance, scratch resistance, impact resistance and coating film retention and cleaning, etc., therefore, coating film hardness is to assess the performance of the lens, coating index.The instrument can be used to conveniently measure the hardness of lens and coating film.

The working principle of

This instrument mainly consists of pencil holder and test-bed, pencil holder and the pillar of four connecting rod structure, which ensure that the weight of the weight bench intersection on the vertical ACTS on the pencil lead and 45 ° Angle and make a pencil with test rig, and stays the same.The test stand can be moved horizontally or vertically to fix the paint pattern and slide the pattern toward the scratches. The pencil traces the pattern onto the pattern.The hardness of the film can be determined by drawing different marks with different pencils.

Product features

1. Suitable for testing the hardness of paint, especially for metal coating, decorative materials and synthetic leather.

2. The test method of pencil hardness tester conforms to ASTMD333,ISO15184, bs 3900-e19, ecca-t4/1.

3. The pencil hardness tester USES the standard hardness to test the scratches on the surface of the tested products.Judge the surface hardness of the product according to the standard pencil hardness marking.

Product features:

1. Adopt high-precision, all-digital speed regulating system and precision reducer to drive precision screw pair for test, realize wide range adjustment of test speed, low noise and smooth operation during test.

2, touch the key operation mode, LCD real-time display.The display interface can display test method selection interface, test parameter selection interface, test operation and result display interface and curve display interface, which is convenient and fast.

3. Digital display of test force, continuous adjustable test speed, automatic stop of sample pulling, peak maintenance and other functions.

4. It can adjust the speed and speed of the beam when the sample is clamped, and has protection devices such as overcurrent, overpressure and overload.

Technical parameters

Measurement Angle: 45 degrees

Test grade: grade 13 (6b-6h) standard zhonghua pencil for hardness test (6B, 5B, 4B, 3B, 2B, B, HB, H, 2H, 3H, 4H, 5H, 6H).

Weight: about 4KG

Load: 500G/250G/250G (three weights)

Method of use

1. The pencil shall be planed, and the graphite shall protrude about 5mm, which can be achieved by using a special pencil planer included in the special scope of supply.Holding the pencil vertically, grind the graphite core down against the sandpaper (particle fineness 400) with sharp edges.

2. Clip the pencil in the instrument, protruding the pencil by 5mm, and place the instrument on the sample surface.Grab the crank with your thumb and forefinger and slide it over the template at about 10cm/s.

3, the choice of the appropriate hardness of the pencil depends on the test.It is recommended to start with a medium soft pencil or a medium hard pencil, and gradually find a suitable pencil.

4. During the test, be careful not to mix up the pencil marks and penetration marks.If necessary, use a wet sponge or a soft eraser to remove excess line marks.

Both types of pencils are marked with a pencil hardness.The hardness of a pencil such as a 2h-3h pencil means that a 2H pencil can leave a mark on the surface while a 3H pencil can slightly cut the paint film, which is 2H hard.
