Scratch resistance tester to determine plastic scratch resistance analysis
With the rapid development of China's economy, automobiles are becoming more and more popular, and automobile inspections are also systematic and formalized. Scratch resistance test is an important indicator for the quality control of plastic parts for automobile interior and exterior decoration. The scratch resistance tester is a test instrument for scratch testing of plastic parts. The principle of plastic scratch resistance test: The scraping head acts on the surface of the sample with a certain pressure, and the scraping head and the test sample move relative to each other at a certain speed, and the movement trajectory is generally a straight line or a circle. When plastic deformation occurs, the surface of the material is destroyed. Factors such as the scratch head, load (pressure), and relative motion of the sample to the scratch head fundamentally determine the method of scratch resistance testing. First of all, the material, shape and size of the scratching head are the key factors in determining the scratching test method. Different tests generally correspond to different scratching heads. The common scraping head is a hemispherical or spherical steel material, which meets certain hardness requirements after heat treatment, with a diameter of 1mm, 0.75mm or 0.5mm; secondly, the load is the pressure applied by the scraping head to the surface of the material. It is also a very critical parameter, which characterizes the severity level of the test. Different scratch resistance test methods have different loading methods, such as weight loading, lever loading and compression spring loading; Conditions, the state of relative motion of the scraping head and the material, such as speed and stroke, are less important parameters. In the early scratch resistance test, manual operation was mostly used, which could not guarantee the consistency of the test speed. However, with the continuous development of the instrumented scratch resistance test equipment, the test speed can be basically kept constant, and the repeatability and reproducibility of the test are improved. improve. Influence of materials and surface parameters on scratch performance: The scratch performance experiment of polymer materials and the need to use finite element digital simulation technology as an aid, we found the effect of surface parameters of polymer materials in the test, so according to the surface parameters of the material The effect of the shed performance is as follows: First, the effect of Poisson in the material on the scratch of the material is negligible. The scratching performance of polymer materials is not necessarily related to the elastic modulus of the material, but under the influence of temperature, the material with the larger elastic modulus is more affected by the scratching. Increasing the yield of the material can reduce plastic deformation and improve the scratch resistance of the material. The smaller the friction coefficient on the surface of the polymer material, the better the scratching performance. The surface texture of the polymer material has a great influence on the friction coefficient, and its form can be changed to improve the scratching property of the material. However, the texture of the surface can hide the scratch marks well, which has great reference value for the surface repair of the car. It is very important to strengthen the material composition of scratch resistance in the analysis of material and surface parameters.
