Drawing method for energy absorption diagram used for paper honeycombed sheet core performance detection

Abstract

The invention relates to a method for detecting paper honeycomb board core, belonging to the honeycomb paper board performance detection and application field, which comprises: using a detector to detect the solid modulus of a honeycomb paper core; building a relationship curve between standardized energy adsorption in unit volume and standardized stress; building an energy adsorption curve of approximate linear form; building a dynamic compression maximum acceleration speed static stress curve, under dynamic compression, analyzing the energy adsorption curve formed by connecting the shoulder points of the energy adsorption curve corresponding to the ratio between the thickness of the honeycomb paper board and the span, to obtain an energy adsorption picture for detecting the performance of the paper honeycomb board core. The energy adsorption picture of the invention can be applied for detecting the performance of paper honeycomb board core, to quickly and accurately optimize the structure and material selection of honeycomb paper boards, thereby providing accurate reference data for the manufacture of honeycomb paper boards under different conditions and realizing energy-saving high-efficiency package.

Description

technical field [0001] The invention belongs to the application field of honeycomb paperboard performance detection, and in particular relates to a method for drawing an energy absorption diagram for detecting the performance of a paper honeycomb board core. Background technique [0002] With the strengthening of people's understanding of resources, environmental protection and sustainable development, environmentally friendly products are more and more popular. As a non-polluting, novel structure, large load-bearing, low cost, good elasticity and good cushioning performance packaging material, honeycomb paperboard has been highly concerned by the packaging industry and has been successfully applied to the packaging of large mechanical and electrical products, furniture, construction materials etc. [0003] At present, due to the lack of a systematic and effective testing method for the cushioning performance of honeycomb paperboard, the design and material selection of the...
