Material performance parameters of caster wheels
Views:2127 Updated:2021-12-04
Beijing Hanke has been focusing on the development and production of casters for more than ten years. The performance parameters of caster materials are as follows: ·Hardness: used to measure the hardness of rubber and other tire treads, expressed by Shore "A" or "D". ·Compressive strength: during the compression test, the maximum compressive stress the test sample bears, in units of banknotes megapascals. ·Elongation: Under the action of tensile force, the ratio of the increase in the distance between the marking lines and the initial gauge length when the test sample breaks, expressed as a percentage. ·Impact strength: the performance of the data to accept the violent impact of free falling heavy objects. It is expressed in inches/pounds, feet/pounds, or punching work at the test temperature. ·Deformation resistance under heavy pressure: the wheel landing place becomes larger and flattened under heavy pressure for a long time, that is, the test sample bears a certain static pressure load, and then the load is removed after the specified pressure time is over, and the wheel landing place changes to the gauge The percentage of the height compared to the original height. ·Working temperature: the working temperature range measured under rated load. ·Water absorption: The increase in the weight of the test sample is expressed as the percentage of the initial weight of the sample after a specific sequence of tests. Weather resistance: such as coatings, plastics, rubber products, etc., used outdoors to withstand the test of weather, such as the comprehensive damage caused by light, cold and heat, wind and rain, bacteria, etc., its resistance is called weather resistance.
