【Abstract】 The treatment of low temperature plasma to the surface of bamboo strips with or without hypodermis can improve the surface wettability and bonding strength of bamboo strips.In this research,treating time,treating distance and treating electrical power of low temperature plasma are investigated.The results show that the treating distance is the strongest affecting factor,followed by treating time and treating electrical power.The optimum technological parameters are as follows: treating time is 5s,treating distance is 10mm,treating electrical power is 650W.Under this treatment condition,bonding shearing strength of the bamboo strips with hypodermics increased by 143.9% with its key coefficient variance(CV) decreasing by 11.9%.Bonding shearing strength of the bamboo strips without hypodermis increased by 45.8% while its key coefficient variance(CV) decreasing by 6.5%.更多还原
