Propiedades físicas y químicas del cuero para calzado de seguridad

Abstract

Se escogieron 86 muestras de calzado de seguridad disponibles en el mercado nacional y se les determinó algunas propiedades físicas y químicas, con los siguientes resultados promedios y sus respectivas desviaciones estándar para las propiedades físicas, espesor: 2,03 (0,22) mm, resistencia a la tracción 2,51 (0,95)kgf/mm2, resistencia al desgarre 12,1 (4,3) y porcentaje de alargamiento a la rotura 66 (13). Las propiedades químicas que se evaluaron fueron el porcentaje de cenizas sulfatadas y el porcentaje de óxido de cromo, obteniéndose los siguientes resultados promedios con sus respectivas desviaciones estándar: 4,9 (1,2) y 3,33 (0,69).
