Hand crank type is easy to operate, load 1000g +/- 1g, scratch speed about 1mm/s, test angle 45 °, standard 6B-6H pencil, in line with a number of international standards, through the pencil Hardness grade to accurately evaluate the scratch performance of the paint film.
Using electric Dial design, the scratch length can reach 60mm, the load range is 0-2000g, and the physical characteristics of the coating are characterized by the anti-penetration ability of the scribing needle.
The paint film adhesion was measured by the circular trace method, the drawing diaMeter was 0-10.5 mm, and the Working Travel was 80mm. The integrity of the paint film was evaluated according to seven grades, and the operation was simple and reliable.
Adopt the circular roller scratch method to evaluate the adhesion grade, describe the adjustable diaMeter of 0-10.5 mm, equipped with four weights to achieve 200-1000g loading, table Travel ≥ 80mm, manual operation is stable and reliable.
The scribing needle is used to act vertically on the film, the load range is adjustable from 0-2000g, the minimum increment is 50g, and the diaMeter of the steel ball is 1mm, which can accurately determine the minimum weight required to cut the paint film.
Using digital touch screen control, the test speed is adjustable from 0-40mm/s, the load range is 0-4000g, the minimum increment is 50g, and it is equipped with a variety of weights and special scribing needles to accurately determine the film scratch resistance performance.
Steel ball diaMeter 1mm needle, load range 0-2000g, through the minimum load of the film to accurately determine the coating resistance to penetration, traverse speed 30-40mm/s to ensure the test Stability.
Using 0.5mm tungsten carbide tip, the spherical test point can scratch 2000 90mm long scratches without damage after durability test, the design is comfortable and stable, and it is suitable for regular interval scratch operation in corrosion test.
The paint film adhesion was measured by the circular trace method, the drawing diaMeter was 0~ 10.5mm, and the Working Travel was 80mm. The integrity of the paint film was evaluated according to seven grades, and the operation was simple and reliable.
Measure the surface of paint film and putty film and the actual drying time, in line with GB/T1728 standard, the weight of the Tester is 200g, and the weight of the bottom area is 1cm ².
Using 200g weight and 1cm ² bottom area design, in line with GB/T 1728 standard, through the filter paper test method to accurately determine the film surface drying and practical drying time, easy to operate, reliable results.
Control system using servo motor, scratch speed 254mm/min, weight free lifting, ensure that the needle parts accurately fall on the workpiece, to achieve automatic scratch and zero operation.
The drying process of paint film and putty film can be accurately measured by using circular track needle design, equipped with four different radius needle (R0.25/0.5/1.0/1 mm), and the track period is 24h/r.
Equipped with Φ 1mm, Φ 0.75mm, Φ 0.50mm three probes and 0-30N spring pressure, using wheel handle design, can be quickly measured in plane and curved surface, no maintenance and anti-corrosion.
Using equilibrating rod and adjustable weight design, the scratch resistance of the material is evaluated by the scraper head leaving an arc score on the surface of the swirl/spin specimen, which is suitable for a variety of rigid and coating materials.
