| Abstract: |
| The work aims to simplify the test methods of mechanical property of slip sheet. By investigating the application characteristics of slip sheet and referring to the relevant Chinese national standards, it was proposed that the materials of slip sheet should be tested regarding such mechanical properties as tension and tearing strengths. The shape and size of the sample prepared and the test methods and conditions were determined. On the basis of that, paper and plastic (two kinds of materials of slip sheet) were tested and verified. During the test of tensile property, the strength of longitudinal test sample was greater than that of the transverse test sample, and the strength of the transverse test sample with indentation was the lowest. During the test of tearing property, the strength of transverse test sample was greater than that of the longitudinal test sample, and the strength of the longitudinal test sample with indentation was the lowest. When the mechanical properties of slip sheet’s material are investigated, only the tension strength of transverse test sample with indentation and the tearing strength of longitudinal test sample with indentation should be considered respectively. By doing so, the minimum strength of slip sheet’s material can be obtained rapidly, so as to calculate the carrying capacity of slip sheet. |
