Apparatus for testing the bond strength between multilayer bonded materials

Abstract

The invention discloses a test device for bonding strength between multilayer bonding materials, which comprises a base, a hydraulic fixing system arranged above the base, a hydraulic mechanism arranged between the base and the hydraulic fixing system; and is arranged on the base The first puller holder for fixing the auxiliary drawing device at the bottom of the sample is set above the first puller holder The second puller holder for fixing the top puller of the sample is set on the hydraulic fixing system A pull-out adjuster, the pull-out adjuster is connected to the second pull-out fixture, and a pull-inductive dynamometer is connected between the second pull-out fixture and the pull-out adjuster, and the The hydraulic mechanism is connected with the pulling regulator for applying force to the sample; the information processing module is connected with the induction force measuring device for obtaining test data. The invention is a bonding strength testing device capable of accurately and conveniently measuring the bonding strength between multilayer bonding materials, and is compatible with traditional bonding strength testing functions.

Description

technical field [0001] The invention relates to a strength testing device, in particular to a testing device for bonding strength between multilayer bonding materials. Background technique [0002] Bond strength is an important index to evaluate the performance of bonded materials. In many current pull-out tests of bonded materials, it is necessary to test the pull-out strength of bonded materials. Among them, the bonding strength between liquid solidified bonding materials and ordinary solid materials has been tested by relatively complete test instruments, and the test results are also relatively accurate. [0003] With the continuous advancement of material technology, the construction industry often encounters the situation of bonding between different bonding materials or layered bonding of the same bonding material, but the current laboratory aims at the bonding between bonding materials in the above cases.

Problems solved by technology

[0003] With the continuous advancement of material technology, the construction industry often encounters the situation of bonding between different bonding materials or layered bonding of the same bonding material, but the current laboratory aims at the bonding between bonding materials in the above cases. The strength test instruments and test methods are not perfect enough. At present, the test instruments for testing the bonding performance of bonding materials are mainly aimed at the bonding performance between liquid binders and solid materials. Taking asphalt materials as an example, the commonly used Asphalt and aggregate bond strength test instruments mainly include manual asphalt puller and automatic puller, etc.

[0004] Therefore, it is impossible to accurately and conveniently test the bond strength performance between multi-layer bond strengths through existing test instruments and means.
