9. All measured data can be exported as WORD documents and BMP standard format picture files
10. Can test any size sample, sheet or profile sample can be measured, super large size requires special customization
11. Solid surface free energy estimation models can be derived and applied to polar, non-polar, low-energy, and high-energy solid surface analysis
Principle
The instrument uses the static droplet method to measure the contact angle, and automatically tests the left corner, right corner and average angle of the droplet in real time through the Opencv graphic profile analysis software. It provides real-time test Linear dispersion and test data Excle list, and has image saving function. At the same time, the hanging drop method is used to measure interfacial tension and CMC, and the interfacial tension value of the test liquid ranges from 0.001mN/m to 1000mN/m.
Applications
Determination and study of wettability between nanomaterials and different active agents; adhesion between inks, metals, and paper in the printing industry; study on the degree of adhesion between adhesives and solids; detection of the degree of wetting of aircraft substrates by rain and fog in the air of the aerospace industry; determination of the contact angle between projectiles and rain and fog in the air in military science; measurement of the forward and backward angles of injecting additives and solids in crude oil during oil extraction; detection of flux adhesion to metals during metal welding; Determination of hydrophilic angle of aluminum foil; Determination of hydrophilic angle of Eletroplating film and various liquid crystal screens
