Ink test surface tension
WebbTest ink. Test inks are liquids with a precisely defined surface tension. According to DIN ISO 8296: 2008-03, these inks have a highly toxic composition of formamide and ethylene glycol. We offer the same range of parameters in a non-toxic composition. Measuring technology . The surface tension measurement value of our inks and test pens was ... Webb23 sep. 2024 · Dyne test ink and dyne test pens are very useful for identifying substrates with problematically low surface tensionsand for determining the level of surface treatment a substrate has acquired through surface treatment.

WebbUntreated PE and PP have a surface tension of about 30 dynes/cm. After treatment for printing with solvent-based ink, PE and PP should have a value of approximately 38-40 dynes/cm. For printing with water-based ink, the surface should have a value of approximately 42-44 dynes/cm. WebbThe ink is applied to the test piece and observed for 3 seconds. If the ink stops and wets the surface, the surface tension of the test object is the same as that of the ink used. If the line contracts, the surface tension of the test object is higher than that of the ink.
WebbIn order to successfully accomplish this the liquid adhesive, or ink should be able to wet the surface of the material. And this is where Corona Treatment and Plasma Treatment technologies are necessary. Wettability depends on one specific property of the surface: Surface energy, often referred to as surface tension.

To work out the units on your own, simply solve the equation with just units. S = kg/m 3 * m * m/s 2 * m. Two of the meter units cancel out two of the per meter units and you are left with 1 kg-m/s 2 /m or 1 N/m. 3. bar band dance songsWebbWetting tension, a measurable property that estimates a film's surface energy, is the maximum liquid surface tension that will spread, rather than bead up, on the film surface. ASTM D 2578 is a procedure for determining wetting tension by applying different test solutions of increasing surface tensions until one is found that just spreads across … bar bancone
