Construcción e implementación de un protocolo mecánico para medir la abrasíon al frote en seco del acabado del cuero

Abstract

In the facilities of the tannery laboratory of the FCP at ESPOCH the construction and implementation of the mediation equipment abrasion dry rub of leather finishing, to evaluate the machine a physical analysis of 8 goat skins were performed they were compared with 8 goat skins in the laboratory of ANCE, once installed the machine, protocol tests were conducted to verify the correct performance and operating efficiency of the machine according to the calculations was 82%. Several pilot tests were compared with the results obtained at ANCE laboratory, it was determined that the absence of statistical difference especially for the tensile strength and elongation percentage, allowing efficiency and accuracy ratification of the results. Operating procedures were established for testing the tensile strength of leather in the equipment prepared for this purpose, operational and security, to ensure proper operability of the machine and above all ensure the accuracy of the data. Production costs of the machine was $ 3,707.25 using high quality materials that are more economical when compared with international production machine according to pilot tests provided results on the measurement of voltage and very similar elongation. It is recommended to perform a simulation mechanism to verify the design and operation of each one of the parts that constitute the machine.
