An adhesion tester for aluminized pvdc film

Abstract

The invention provides a detector used for measuring adhesive force of an aluminized PVDC thin film, and belongs to the technical field of machinery. The detector is capable of solving technical problems of existing technology that thin film adhesive force detection accuracy is low, and the like. The detector comprises a platform plate, an electrical cylinder, a guide rail arranged in parallel with the electrical cylinder, and a top plate; the upper plate surface of the platform plate is provided with thin film clamps and a supporting plate; the supporting plate is arranged between the two thin film clamps; the electrical cylinder is slidingly connected with a slide block; the front side of the top plate is connected with the slide block, and the back side of the top plate is slidingly connected with the guide rail; the lower plate surface of the top plate is fixedly provided with a connecting rod; the lower end of the connecting rod is connected with a rotating disk; the lower disk surface of the rotating disk is fixedly provided with an adhesive tape holder; the adhesive tape holder is provided with a stationary shaft; the stationary shaft is sieved with an adhesive tape coil; the adhesive tape coil is enwinded by adhesive tape; the adhesive tape comprises an adhesive surface and a detecting surface which are arranged oppositely; the adhesive surface is capable of bonding with the aluminized PVDC thin film; and the detecting surface is provided with grids. The detector is capable of increasing thin film adhesive force detection accuracy.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an adhesion tester for aluminized PVDC films. Background technique [0002] Aluminized PVDC film is a barrier film formed by depositing a thin layer of aluminum atoms on high-quality PVDC film through vacuum aluminum plating process. It has bright metallic luster, excellent gas and light barrier properties, and good moisture resistance. Heat resistance, puncture resistance, can replace aluminum foil and other features. [0003] As an aluminized film, the adhesion of its aluminum layer is an important index to measure the performance of the film. In the prior art, the method for detecting the adhesion of the aluminized PVDC film is usually as follows: the 3M adhesive tape is attached to the aluminized PVDC film. layer and flatten it, then peel off the tape at a uniform speed, observe and estimate the peeled area of ​​the aluminized layer, if the area is less than 10%, it is the fi...

Problems solved by technology

[0004] However, the above-mentioned methods are all done manually, and the detection is done manually. When the tape is manually pasted on the film, when the tape is pulled away from a certain distance, the manual can not ensure that the tape is still in a straight line, then when the tape is flattened On the aluminized PVDC film, bubbles or wrinkles may appear; and when the tape is torn from the aluminized PVDC film, the speed cannot be effectively controlled, and these will directly affect the experimental data and reduce the detection accuracy

Moreover, in the prior art, when calculating the peeled-off area of ​​the aluminum coating, there is no more accurate method, and it is only done by estimation, which further reduces the detection accuracy
