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.
Adopting stepless speed regulation technology, the friction speed range is 0~ 135cpm, the test Travel 155mm, the number of times can be set and automatically counted to evaluate the sanding performance of undercoated putty.
The device places the test plate in parallel in the wind tunnel, the wind speed control accuracy is 3 +/- 0.3m/s, the drying time is automatically controlled, and the surface crazing can be visually inspected, which is suitable for the evaluation of coating anti-crack performance.
Friction speed 0~ 135cpm, Test Travel 155mm, round-trip count 0~ 9999, suitable for accurate determination of sanding performance of undercoat and putty.
Easy to use magnetic suction Cup loading and unloading, sanding times 0~ 9999 two-way count, friction load 570 +/- 20g, additional weight adjustment load, suitable for undercoating and putty anti-sanding performance test.
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.
The device provides 3 +/- 0.3m/s wind speed through axial flow fan in wind tunnel, Timer delay range of 0.01 seconds to 99 hours 99 minutes, can automatically control drying time and eye test plate surface crazing, support parallel test.
The wind speed is controlled in the range of 3 +/- 0.3m/s, equipped with axial flow fan and automatic timing function, which can simulate the drying process under specified conditions and effectively detect the surface crazing of the material.
The motor-driven edge rises at a rate of 3mm/min to generate and control crazing expansion, which can detect the crazing ability of putty against substrates, with a maximum lift of 20mm, suitable for standard frame 200 × 150mm test plates.
Measurement accuracy 0.02mm, can control the slow expansion of crazing, test putty layer anti-substrate crazing ability.
Using stainless steel material, bottom area 1cm ², weight 200g, in line with GB/T 1728 standard, can accurately determine the film and putty film surface drying time.
The axial flow fan is used to supply air and support stepless speed regulation of 0~ 3m/s, and the anemoMeter has a range of 0~ 10m/s, which is suitable for the determination of the initial drying anti-cracking performance of laminated architectural coatings.
The equipment can detect the crazing or peeling of the putty film after bending, equipped with R25 and R50 support film specifications, shaft Rod size is 50mm and 100mm in diaMeter, suitable for 0.2-0. 3mm thick tinplate plate.
Using axial flow fan and test wind tunnel structure, the wind speed can be adjusted in the range of 3 +/- 0.3m/s, equipped with Timer delay range of 0.01 seconds to 99 hours and 99 minutes, automatic detection of material surface crazing.
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.
