Scratch resistance detection method for glass substrate

Abstract

The invention relates to a method for detecting scratch resistance of a glass substrate. The method comprises the following steps: fixing a to-be-tested glass substrate; scribing a track of a preset distance on the surface of the to-be-tested glass substrate at a preset speed through a pressure head under continuously increasing preset pressure; in the track scribing process, recording the scribing distance of the pressure head, monitoring the actual bearing pressure of the glass substrate to be tested in real time, and obtaining a scribing distance-actual bearing pressure curve; and taking an actual bearing pressure value at a second inflection point on the scribing distance-actual bearing pressure curve as the scratch-resistant critical load of the glass substrate to be tested. According to the test method, the actual bearing pressure value of the to-be-tested glass substrate is measured while the to-be-tested glass substrate is scratched, and the scratching distance-actual bearing pressure curve can be output after the scratch is scratched, so that the scratch-resistant critical load of the to-be-tested glass substrate can be obtained according to the curve, the test process is convenient and fast, the actual scratch condition is met, and the test method can rapidly obtain the scratch resistance of the glass substrate to be tested.

Description

technical field [0001] The invention relates to the technical field of performance detection of glass materials, in particular to a scratch resistance detection method of a glass substrate. Background technique [0002] With the wide application of electronic display devices, more and more users have higher requirements for the quality of electronic display devices, and need to maintain a good display effect during long-term use. The touch screen substrate of electronic equipment is used in actual use. Scratches are often caused by external forces, resulting in rough surface and reduced smoothness of the glass substrate, which will seriously affect the display effect and touch feel. Therefore, it is necessary to evaluate the scratch resistance of the glass substrate. [0003] However, the existing glass scratch resistance evaluation generally uses a Vickers hardness tester to form an indentation on the material surface, and obtain the hardness value by measuring the diagonal...
