The waste plastic film collected by machine contains a large amount of impurities such as straw and root stubble.The differences in physical and mechanical properties of each component of the film straw mixture affect the subsequent mechanical separation effect.This article statistically analyzes the proportion of components in the film straw mixture,and determines the tensile properties of cotton straw and waste plastic film after one production season.The experimental statistical results show that sand accounts for 46.28%,straw accounts for 30.20%,stubble accounts for 6.29%,and plastic film accounts for 17%in the film impurity mixture.The determination of mechanical properties of cotton stalks shows significant differences in mechanical properties among different diameters of cotton stalks,with a compressive strength range of 16.75～24.63 Mpa and a flexural strength range of 22.68～27.69 Mpa.The test results of the tensile properties of the plastic film show that the tensile strength of the plastic film is 1.28 N.The research results provide a basis for the structural design and working parameter determination of the separation device for film impurity mixture.
