Device for measuring the surface energy of materials

The present invention is a device for measuring the surface energy of a material. The device includes a pulling mechanism and a clamp. A film, including an adhesive side, is attached to a surface to be measured. The film is clamped to surface energy measuring device. The device is placed flush on the surface. A pulling mechanism is pulled until a triangular piece of film tears and is removed from the surface. The device is then lifted off of the surface and a measurement is made at the pre-calibrated marking nearest the tip of the triangle torn into film. 1. A surface energy measuring device , comprising:a box;a pulling mechanism;a dashpot, wherein said dashpot regulates pulling speed;a sliding platform, wherein said sliding platform is connected to said dashpot by a means of connection; anda clamp;a tongue and groove joint, wherein said clamp is attached to said sliding platform by said tongue and groove joint;a tape.2. The device of claim 1 , further comprising a knob claim 1 , wherein said knob controls the velocity of said dashpot.3. The device of claim 1 , wherein said means of connection connecting said sliding platform and said dashpot is an L-bracket.4. The device of claim 1 , wherein said clamp further includes a compression spring and an adjustment screw.5. The device of claim 1 , wherein said tape is a consumable graduated thin-film adhesive.6. The device of claim 1 , wherein said tape further comprises a tab.7. The device of claim 6 , wherein said tape further comprises notches.8. The device of claim 7 , wherein said tape further comprises pre-calibrated markings claim 7 , wherein said pre-calibrated markings correspond to surface energy measurements.9. The device of claim 1 , further comprising a retaining nut claim 1 , wherein said retaining nut is attached to said L-bracket and said sliding platform.10. The device of claim 1 , wherein said box is rectangular shaped.11. The device of claim 1 , wherein said box is wooden.12. A method for measuring the ...
