Traction (mécanique)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this paper, the pearson product moment correlation coefficient analysis method is used to show that the tensile strength of RL/CR is highly positively correlated with the elongation at break, the bursting height is highly positively correlated with the bursting strength, the tensile strength is highly positively correlated with the bursting strength, and the bursting height is negatively correlated with the elongation at break. The air permeability of RL/CR is not correlated with 15 minutes water absorption, but is negatively correlated with 24 hours water absorption and surface wettability ; The 15 minutes water absorption of RL/CR is negatively correlated with the 24 hours water absorption and the surface wettability ; The surface wettability is positively correlated with 24 hours water absorption.
The tensile strength of RL/CR is negatively correlated with air permeability, highly positively correlated with 15 minutes and 24 hours water absorption, and highly negatively correlated with surface wettability. The bursting strength of RL/CR is negatively correlated with air permeability and 15 min water absorption, and highly positively correlated with 24 hours water absorption and surface wettability.Note de contenu : - Introduction to correlation analysis of RL/CR

Produits et matériaux recyclésIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this paper, the AHP (Analytic Hierarchy Process ) method is used to establish the mathematical model of four influencing factors, namely the amount of sizing, hot pressing temperature, hot pressing pressure and hot pressing time, regarding the physical and mechanical properties and comprehensive properties of RL/CR (RL recycled leather, CR chloroprene rubber adhesive). The analysis shows that the influencing laws of each factor on the total physical and mechanical properties of RL/CR and each of the typical physical and mechanical properties is basically consistent. The influence weights in order from high to low are: the amount of sizing, hot pressing pressure, hot pressing temperature and hot pressing time, among which the influence of hot pressing time on RL/CR performance is very weak and can be ignored.
