Using photo paper smooth surface combination technology, observing the imprint after applying a uniform load, the pressure range of the probe is 50-250N, and the diaMeter of the rubber probe is Φ 40mm, which can accurately evaluate the chalking grade of the paint film.
The pressure range of the probe is 50~ 250N, the diaMeter of the rubber probe is 40mm, and the degree of paint film chalking is evaluated by comparing the imprint of the photo paper with the standard sample, which is suitable for the detection of various environmental factors.
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.
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.
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.
Using 500g weight and 1cm ² bottom area, after tacking the paint film at a specific temperature Humidity test, the operation is simple, and the drying state is evaluated by the adhesion of the filter paper fibers.
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.
Using film lamination technology, with excellent solvent and chemical resistance, paper Film thickness 0.29mm and no fluorescent whitening agent to ensure Spreader uniformity and test accuracy.
