Impacto del comportamiento de la viscosidad en compuestos de la cubierta de rodamientos para llantas PLT

Abstract

This preliminary project addresses the impact of rubber viscosity behavior on the compounds of bearing covers for PLT tires at Continental Tire Andina. A problem has been identified in the variability of the compounds' viscosity, especially in the case of the T01004 compound, which has exceeded the acceptable annual failure limit. The research was conducted using a non- experimental descriptive methodology, utilizing various measurement tools, check sheets, forms, and observation for data collection. Subsequently, the ANOVA statistical technique was applied to quantitatively assess the impact of viscosity on the extrusion process and the final quality of the bearings. In addition to viscosity, other variables affecting the bearing length were identified. In the case of the T01004 compound, these variables include continuous weight and screw RPM (150). For the T14663 compound, the additional variables are continuous weight, preform temperature, and cylinder 1 temperature (150). This highlights the complexity of the production process. The operational variability and behavior of the variables are notably similar, despite the differences in stability between the T01004 and T14663 compounds. The objective was not only to understand this impact but also to find the most efficient and optimal way to produce bearings, thereby directly benefiting Continental Tire Andina.
