LS-SDC-1000 Large platform optical contact Angle Tester
Samenvatting
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.
LS-SDC-1000 type platform contact Angle measurement instrument is using the principle of optical imaging, image contour analysis way to measure the surface contact Angle, bevochtigbaarheid, grensvlakspanning van de tafel, oppervlakte energie, zoals prestaties, equipment cost-effective, comprehensive functions, high test precision and can meet the large size products, such as TV flat glass and other special products with conventional sample measurement needs.

Toepassing
Contact Angle measuring instrument is widely used in various industries, in mobile phone manufacturing, glas productie, oppervlakte behandeling, materiaal onderzoek, chemistry and chemical industry, halfgeleider productie, coating inkt, elektronisch circuit, textielvezel, medische biologie en andere gebieden, contacthoekmeting is een belangrijk instrument geworden om de oppervlakteprestaties te evalueren.
(Some test functions need special accessories to be purchased)
- The wetting behavior of liquid on solid surface such as spreading, penetratie en absorptie, and the static contact Angle is measured by the block drop method;
- Forward Angle, achterwaartse hoek, contact Hoekvertraging, rolling Angle and dynamic contact Angle measurement of material on solid surface;
- Continuous real-time research and process recording of absorbing materials, and curve analysis of contact Angle change with time;
- Measurement of contact Angle of various special materials, zoals poeder, gebogen oppervlak, superhydrophobic/superhydrophilic samples;
- Attachment drop method to test the contact Angle of materials immersed in liquid;
- Suspension drop method is used to measure the interfacial tension and its polarity and dispersion components of various liquid surfaces.
