Abstract

The invention relates to an abrasion test device and a test method, in particular to a mortar abrasion test device and a test method. The abrasion test device comprises a motor, a drive system, a mortar charging barrel, a rotating shaft and a supporting frame. The drive system consists of a primary driving wheel, a secondary driving wheel and a connecting piece, wherein the primary driving wheel is fixed at an output shaft end of the motor, and the secondary driving wheel is positioned on one side of the motor and in the same plane with the primary driving wheel. The rotating shaft is fixed on an outer shell through a bearing, one end of the rotating shaft is connected with the secondary driving wheel of the drive system, and the other end of the rotating shaft stretches into the mortar charging barrel which is fixed on the outer shell. The motor drives the rotating shaft through the drive system to perform synchronous rotation. The abrasion test method comprises the following steps of: fixing a sample on the rotating shaft, and filling a grinding mortar which is formed by mixing quartz sand and water into the mortar charging barrel; starting the motor to perform an abrasion test, and when the temperature of the mortar is overhigh, adding water for cooling; and taking the sample out after the test, and calculating the abrasion ratio of the sample. By the device and the method, the test efficiency is high, the time consumption is less, the test data deviation is small, and the accuracy is high.

Description

technical field [0001] The invention relates to an abrasion test device and method for measuring the friction and wear properties of various types of materials including plastics, rubber, metal and ceramics, especially the abrasion properties of ultra-high molecular weight polyethylene. More specifically, the present invention relates to a mortar abrasion test device and method. Background technique [0002] The evaluation of wear resistance of materials is determined under certain test conditions according to certain test methods. Therefore, the test methods and instruments are extremely important to the scientificity of the tribological performance test of materials and how to reflect the systematicness of the tribological performance of materials. The standards for evaluating the wear resistance of plastics in my country include GB / T 3960-83 "Test method for sliding friction and wear of plastics", which is suitable for measuring the sliding friction and wear properties o...
