Embodiment 1

[0024] Selected sample Y, the standard value Hv of the standard micro-Vickers hardness block = 443, the test adjustment is: t is 25s, F is 200g; 5 testers test the same sample, and finally calculate the average value for correction, the result The summary is as follows:

[0025] Table 15 Testers test values ​​and correction values ​​for multiple tests on the same sample

[0026] Testers Sample test value standard microscopic dimension correction value A 560.9 452.1 549.4 B 541.2 438.0 547.3 C 551.1 445.6 547.9 D 534.8 438.4 540.4 E 526.3 433.7 537.3 extremely bad 34.6 18.4 12.0 standard deviation 12.1 6.5 4.7

[0027] After summarizing the results, it can be seen that the test range of the 5 testers for the sample is 34.6. After using the standard micro-Vickers hardness block test correction, the correction result drops to 12.0, which is within the error range of the instrument (±15.0 ), the data is valid....

Abstract

The invention discloses an electronic glass Vickers hardness test deviation correcting method, which relates to the field of liquid crystal glass testing. The electronic glass Vickers hardness test deviation correcting method comprises the steps of: 1) measuring Vickers hardness values of a standard microscopic Vickers hardness block and a sample to obtain a test value of the standard microscopicVickers hardness block and a test value of the sample, wherein the test conditions of the standard microscopic Vickers hardness block and the sample are the same; and 2) correcting the test deviationof the sample by utilizing the deviation between a standard value and the test value of the standard microscopic Vickers hardness block. According to the electronic glass Vickers hardness test deviation correcting method disclosed by the invention, the electronic glass Vickers hardness test deviation is effectively reduced through introducing the test of the standard microscopic Vickers hardness block and carrying out simple data processing.

Description

technical field [0001] The invention belongs to the field of liquid crystal glass testing, in particular to a method for correcting the deviation of electronic glass Vickers hardness testing. Background technique [0002] Hardness refers to the ability of a solid material to resist the force of other external objects without producing residual deformation. The hardness of glass mainly depends on the chemical composition and structure. In the process of developing the glass frit, the Vickers hardness of the glass is captured, and the frit is adjusted according to the relationship between hardness and chemical composition, so as to obtain electronic glass with suitable hardness. The Vickers hardness test process is as follows: Use Vickers diamond square cones to indent the glass surface with a certain load force and load time, observe the selected indentation boundary with the help of a microscope system, and calculate the diagonal length of the indentation; through the follo...
