Principle
The instrument uses Opencv graphic profile analysis software for real-time automatic testing. The left corner, right corner and average angle of the droplet are tested by the static droplet method, and real-time Linear dispersion and Excel data lists are provided. The dynamic test analyzes the forward angle, backward angle and tilt angle by the turning method. The hanging drop method measures interfacial tension and CMC, and the test range is 0.001mN/m~ 1000mN/m.
Applications
Measurement of wettability of nanomaterials and active agents, inks metal paper adhesion in the printing industry, study of adhesion degree between adhesives and solids, rain and fog wetting detection in the aerospace industry, measurement of contact angle of military science shrapnel, measurement of oil extraction additives and crude oil angle, metal welding flux adhesion detection, determination of hydrophilic angle of aluminum foil, determination of hydrophilic angle of Eletroplating film and liquid crystal screen
Standards
SY/T5153-2007、ASTM D 724、ASTM D5946-2004、ISO15989、IEC6207、GBT22638.9-2016
Steps
1. Automatic set titration system
2. Set the droplet volume and titrate automatically
3. The software tests the droplet size in real time and records it
4. Select the test method (static drop method, dynamic test, or suspended drop method)
5. Image acquisition and analysis
6. Data export and report generation
Notice
• Super large size samples need special customization
• Ensure WINDOWS 64-bit Operating system
• Regularly calibrate syringe accuracy
• Avoid strong light interfering with image acquisition
• Check fixture fixation before testing
