Speed influence on the recycled high-density polyethylene/HDPE handles, tested with a specific adapted industrial method

This article studies the influence of the tensile speed when testing plastic products used to transport containers that may contain various liquids (drinking water, windshield fluid, cleaning agents, etc.). This case study was conducted on certain parts, generally called "handles", which are basically plastic items obtained largely from recycled technological waste resulting from the injection process of various packaging related to the food industry polyethylene caps and lids more precisely. During the handling and transport process, these parts are subjected to various static stresses, therefore, a minimum mechanical resistance is required. Fatigue stress has not been performed due to a limited number of duty cycles. To determine these quality characteristics, multiple measurements of tensile strength and elongations were performed at different traction speeds, measurements that have been validated on the market for several years. We have observed that testing speed over 500 mm/min is not necessary because the tensile strength values do not vary significantly. These results are very important in determining the constructive form of these products and the methods for validating quality indicators. Also, we have proposed to identify a method able to assess the mechanical performance of the product used in nonstandard conditions. The study can be used for a much wider range of similar applications in the plastics industry. En este artículo se estudia la influencia de la velocidad de tracción a la hora de ensayar productos plásticos utilizados para transportar contenedores que pueden contener diversos líquidos (agua potable, líquido parabrisas, agentes limpiadores, etc.). Este caso de estudio se realizó sobre determinadas piezas, generalmente denominadas “asas”, que son básicamente artículos de plástico obtenidos en gran parte de residuos tecnológicos reciclados resultantes del proceso de inyección de diversos envases relacionados con la industria alimentaria como tapas y cubiertas de polietileno. Durante el proceso de manipulación y transporte, estas piezas están sujetas a diversos esfuerzos estáticos, por lo que se requiere una mínima resistencia mecánica. La tensión de fatiga no se ha realizado debido a un número limitado de ciclos de trabajo. Para determinar estas características de calidad, se realizaron múltiples mediciones de resistencia a tracción y alargamientos a diferentes velocidades de tracción; estas mediciones han sido validadas en el mercado
