LR-SDC-1500 Hoge temperatuur vacuümcontact-hoektester
Samenvatting
Contacthoek verwijst naar de raaklijn van het gas-vloeistofgrensvlak gemaakt op het snijpunt van gas, vloeibare en vaste fasen, dat is de hoek θ tussen de vloeistofzijde en de grens tussen vaste stof en vloeistof. Het meten van de contacthoek is momenteel de belangrijkste methode voor detectie van oppervlakteprestaties.
