Detection method for improving wear resistance test precision

Abstract

The invention relates to a detection method for improving wear resistance test precision, and belongs to the technical field of ground material wear resistance tests. The detection method comprises the following steps that S1, a wear resistance test machine is installed; S2, a tester pours grinding materials into a collecting box through a material receiving opening, the collecting box is shaken, and a material suction pump pumps the grinding materials on a second screen into a grinding material box; S3, a test piece is placed on a push plate by the tester, and the push plate slides to enable the test piece to be close to a grinding wheel; S4, a driving assembly is controlled to pull a valve plate to open a discharging opening, the grinding wheel is rotated, a vibration assembly is controlled to vibrate a material screening frame, the material suction pump is controlled to continuously pump the grinding materials in the collecting box into the grinding material box, and when the grinding materials in the collecting box are too few, the grinding materials are poured into the collecting box; S5, all actions are stopped after a period of time, the test piece is taken out, and the surface abrasion condition of the test piece is detected. The method has the effects that the thickness and the size of the grinding materials can be guaranteed, and the test precision is improved.

Description

technical field [0001] The invention relates to the technical field of wear-resistant tests of ground materials, in particular to a detection method for improving the precision of wear-resistant tests. Background technique [0002] At present, wear resistance is an important performance of building materials such as concrete, stone, cement mortar, etc. Due to the difference in materials and process errors in the actual production process, the actual parameters of the building materials may differ from the design data, so it is necessary to do it in practice. Take out part of the test piece of the manufactured product, test the real data of the test piece, and obtain the wear resistance of the test piece. The test requires the use of a wear-resistant testing machine, which rubs the test piece through steel wheels and abrasives, and then detects the wear on the surface of the test piece to obtain the wear-resistant data of the test piece. [0003] The above-mentioned existing...

Problems solved by technology

[0003] The above-mentioned existing technical solutions have the following defects: when the wear-resistant testing machine is performing the wear-resistant test, due to the different thicknesses of the abrasive itself, the experimental results will be biased. Now, although multiple tests are used to calibrate the test results method, but the final test results may still be biased
