The Research of Flat Crush Performance and Processing Technology for Dual-core Honeycomb Paperboard

To Solve the Conflict between cost and compressive strength of honeycomb paperboard,dual-core honeycomb paperboard is designed.Based on the processing technology of single-core paperboard,the processing technology of dual-core honeycomb is identified.Using production equipment of Tanghai Yuan Ming Tangshan, Hebei Province,Ltd.Honeycomb,110g/m~2 and 220g/m~2 paper core composed of 20mm thick dual-core honeycomb samples is produced.Through flat compression properties and the finite element method,using two kinds of honeycomb performance of the simulation analysis of experimental data and simulation analysis by the dual data Verify,the level dual-core honeycomb has been a substantial increase in compression performance.Through cost analysis,the new dual-core Honeycomb costs less,is a highly cost-effective materials.
