Adhesive tape initial viscosity testing machine

Abstract

An adhesive tape initial viscosity testing machine comprises a bottom plate (1), supporting columns (2), a storage box (3), inclined supporting plates (4), an inclined plate (5), a gradienter (6), an ejector block (7), an inclined plate center shaft (8), an ejector block center shaft (9) and a dial (10). The supporting columns (2) are arranged at the four corners of the bottom plate (1), the two inclined supporting plates (4) are symmetrically and fixedly installed in the middle of the upper side of the bottom plate (1), and the inclined plate center shaft (8) is fixed between the two inclined supporting plates (4). The machine is characterized in that the dial (10) is installed on one side of one inclined supporting plate (4), the center of the dial (10) and the center of the inclined plate center shaft (8) are concentric, and a pointer (10-1) is arranged on the inclined plate center shaft (8). By means of steel balls with different diameters and weights and inclined faces, initial viscosity of adhesive tape is tested, the accurate viscosity value of the adhesive tape is finally calculated, the machine is convenient and quick to use, and labor and save are saved.

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.
