LR-SDC-1000 Optischer Kontaktwinkeltester mit großer Plattform

Zusammenfassung

Contact Angle refers to the tangent line of gas-liquid interface made at the intersection point of gas, liquid and solid phases, which is the Angle θ between the liquid side and solid-liquid boundary. The measurement of Contact Angle is the main method of surface performance detection at present.

LR-SDC-1000 type platform contact Angle measurement instrument is using the principle of optical imaging, Bildkonturanalyse zur Messung des Oberflächenkontaktwinkels, Benetzbarkeit, Grenzflächenspannung des Tisches, Oberflächenenergie, wie zum Beispiel Leistung, Ausrüstung kostengünstig, umfassende funktionen, high test precision and can meet the large size products, such as TV flat glass and other special products with conventional sample measurement needs.

LR-SDC-1000 Optischer Kontaktwinkeltester mit großer Plattform

Anwendung

Kontaktwinkelmessgeräte werden in verschiedenen Branchen häufig eingesetzt, in der Mobiltelefonherstellung, Glasherstellung, Oberflächenbehandlung, Materialforschung, chemistry and chemical industry, Halbleiterfertigung, Beschichtungstinte, electronic circuit, Textilfaser, medizinische biologie und andere bereiche, Die Kontaktwinkelmessung ist zu einem wichtigen Instrument zur Bewertung der Oberflächenleistung geworden.

(Some test functions need special accessories to be purchased)

  1. The wetting behavior of liquid on solid surface such as spreading, penetration and absorption, and the static contact Angle is measured by the block drop method;
  2. Forward Angle, Rückwärtswinkel, Kontaktwinkelverzögerung, rolling Angle and dynamic contact Angle measurement of material on solid surface;
  3. Continuous real-time research and process recording of absorbing materials, and curve analysis of contact Angle change with time;
  4. Messung des Kontaktwinkels verschiedener Spezialmaterialien, wie zum Beispiel Pulver, gebogene Oberfläche, superhydrophobe/superhydrophile Proben;
  5. Attachment drop method to test the contact Angle of materials immersed in liquid;
  6. Suspension drop method is used to measure the interfacial tension and its polarity and dispersion components of various liquid surfaces.
  7. Calculation of Surface free energy of solid and analysis of polar dispersion component;
  8. Analyze the adhesion energy of liquid on solid surface and evaluate the uniformity and cleanliness of solid surface.
