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 motor is used to drive the top edge to rise, the edge length is 150mm, and the rising rate is 3mm/min, which can accurately test the dynamic anti-cracking performance of the material against the crazing expansion of the substrate, and the operation is light and stable.
Measurement accuracy 0.02mm, can control the slow expansion of crazing, test putty layer anti-substrate crazing ability.
Maximum moving distance 10mm adjustable, accuracy of 0.01mm, running speed 0.01~ 20mm/min, can monitor the real-time stress of coatings, simulation of concrete cracking movement.
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.
The cone shaft is used to test the anti-cracking performance of coatings with different curvatures. The size of the cone shaft is Φ 3.1~ 38mm, the volume is small and the weight is light, which is convenient for laboratory and field use.
Adopting axial flow fan to supply air, the wind speed can be adjusted steplessly, the wind speed in the wind tunnel is 3 +/- 0.3m/s, and it is equipped with Handheld AnemoMeter measurement, which is suitable for coating drying anti-crack performance testing.
Using large torque stepper motor to achieve automatic reset to zero, indentation accuracy of 0.01mm, support 0.1-0 mm/s adjustable speed, through the indentation depth to determine the minimum depth of coating cracking or disengagement.
Punch diaMeter 20mm, indentation accuracy +/- 0.05mm, maximum depth 10mm, can measure the minimum depth of cracking or from the substrate of the coating, support single and double top coating test, equipped with digital display resolution 0.01mm.
The punch is pushed to the test plate at a constant speed of 0.2 +/-0.1mm/s, and the thickness range of the test plate is 0.30-1. 25mm, which can detect the degree of coating cracking and is suitable for testing of various materials.
