2. High Accuracy Level Control, Combined with Hardware and Software Level Correction
3. Aviation aluminum body, light and stable
4, automatically calculate the contact angle, support left and right contact angle comparison
5. Dynamic contact angle analysis system, including time change analysis, forward angle/backward angle, tilt angle, roll angle
6. Solid surface energy estimation, support Fowkes one-liquid method, Owen two-liquid method, Zisman method, Acid-Based method
7, the software comes with luminance correction function
8. Test methods: hanging drop method, seat drop method (static drop method)
9, surface tension measurement: hanging drop method (young's equation)
10. Database management functions: query, backup, compression, export EXCEL tables
11. The operation calculation software is based on WIN XP and VIAST systems
Principle
The instrument uses image analysis method to capture droplet images through CCD camera and image acquisition system, and automatically analyzes the contact angle value using professional software. Compared with force measurement method, image analysis method has lower Environmental requirements, can test various shape items, and supports high temperature conditions. Surface tension measurement.
Applications
Metal welding, printing industry, adhesive research, aerospace industry, military science, oil exploration, nanomaterials research, aluminum foil hydrophilic angle determination
Steps
1. Adjust the position of the storage table
2. Adjust the luminance of the backlight screen
3. Adjust the position and angle of the injection rack
4. Inject the sample solution
5. Capture images using a CCD camera system
6. Analyze contact angle or surface tension data through software
Notice
• Ensure that the sample thickness does not exceed 35mm
• Power supply voltage is 220V/50Hz before use
• Avoid testing on non-horizontal sample stages
• Pay attention to manual micro control when injecting samples
• Regularly back up the database to prevent data loss
