单瓦楞钙塑纸板强度与电晕功率关系的实验研究

Experimental Study on the Relationship of Single-corrugated Plastic Board Strength and the Corona Power

目的研究电晕功率对单瓦楞钙塑纸板性能的影响。方法通过实验方法对经不同电晕功率(30,60,90,120,150 W)处理后生产的单瓦楞钙塑纸板的剥离强度、平压强度和戳穿强度进行研究。结果在仅考虑电晕功率影响的条件下,单瓦楞钙塑纸板在功率为60 W时剥离强度取得最大值319.5N。不同功率下,平压应力-应变变化趋势相似,在功率为90 W时应力取得最大值0.316 MPa。在功率为90 W时,戳穿强度取得最大值12.57 J。结论通过对实验数据进行拟合,得出单瓦楞钙塑纸板的剥离强度、平压强度和戳穿强度随电晕功率的增加呈先增加后降低的趋势,并且分别在电晕功率为86.7,92.692,89.5 W时取得最大值。

Objective To study the effects of corona power on the properties of single-corrugated calcium plastic board. Methods The peel strength, compression strength and puncture strength of single-corrugated calcium plastic board produced after treatment with different corona power（30, 60, 90, 120, 150 W） were studied through experimental methods.Results When only considering the influence of corona power, the single-corrugated calcium plastic board achieved the maximum peel strength of 319.5 N when the corona power was 60 W. The flat compression stress-strain showed similar trends under different power. When the power was 90 W, the maximum stress value of 0.316 MPa was achieved, and the maximum puncture strength was 12.57 J. Conclusion By fitting the experimental data, it was concluded that the peel strength, compression strength and puncture strength of single-corrugated calcium plastic board first increased and then decreased with the increasing electric power, and the maxima were obtained when the corona power was 86.7, 92.692 and89.5 W, respectively.
