A tape initial tack tester

Abstract

An adhesive tape initial tack tester, which consists of a bottom plate (1), a support column (2), a storage box (3), an inclined plate support plate (4), an inclined plate (5), a level (6), and a top block (7 ), the central axis of the inclined plate (8), the central axis of the top block (9), and the dial (10). Symmetrically installed and fixed at the middle position above the bottom plate (1), the central axis of the slant plate (8) is fixed between the two slant plate support plates (4), and the feature is that the dial (10) is installed on the slant plate On one side of the support plate (4), the center of the dial (10) is concentric with the center axis (8) of the sloping plate, and a pointer (10‑1) is also arranged on the central axis (8) of the sloping plate. The present invention uses steel balls of different diameters and masses and inclined planes to test the initial adhesion of the adhesive tape, and finally calculates an accurate adhesive value of the adhesive tape, which is convenient, quick, labor-saving and time-saving.

Description

technical field [0001] The invention relates to the technical field of graphite film processing and detection, in particular to a testing machine for the initial tack of graphite film adhesive tape. Background technique [0002] Graphite film is a brand-new heat conduction and heat dissipation material. Graphite film contains superconducting thermal graphite components, and has super high thermal conductivity. Graphite film is a high-crystallinity rolled by advanced Taiwan-forming technology and chemical methods in a high-temperature environment. degree of sheet-like material. The biggest advantage of graphite heat conduction film is that it can dissipate heat evenly along the film plane direction. Compared with traditional metal materials, its thermal conductivity is 3-5 times that of copper and aluminum. Heat conduction along the film direction, quickly convert point heat source into surface heat source, high chemical stability, good corrosion resistance and high temperat...

Problems solved by technology

After the graphite film is processed, it needs to be taped. The stickiness of the tape directly affects the quality of the final product. There are many ways to test the stickiness of the tape. At present, the most commonly used method is to use two tapes to bond together for tensile testing. Calculate the final adhesive tape, but the test efficiency of this method is relatively low, the error is large, there are many steps, and it is labor-intensive and time-consuming. Therefore, it is particularly important to design a simple adhesive tape tester to improve the detection quality and shorten the detection time.
