摘要: 以棉花种植田为单翼迷宫式滴灌带自然暴露老化试验田和UVA-340荧光紫外灯管作为紫外光人工加速老化光源,研究分析连续3年的人工加速光老化与自然气候暴露老化试验两者的相关性。结果表明,紫外灯辐照度控制在0.68 W/m2、黑板温度为60 ℃、冷凝温度为60 ℃、光照3 h、冷凝3 h、风吹10 min等试验条件下,人工老化12 d的试样断裂伸长率的保持率平均为84.4 %,而棉花田自然暴露老化150 d为78.8 %,变化规律比较接近,说明有较好的相关性。

Abstract: The aging rate of drip irrigation tape in a cotton planting field was compared with that under a UVA-340 lamp. For artificial accelerated radiation, the strenth was 0.68 W/m2, blackboard temperature was 60 ℃, the condensing temperature was 60 ℃, expose time was 3 h, condensing time was 3 h, wind-blowing for 10 min, the reservation rate of elongation at break was 84.4 % after 12 days, while for the natural condition, the rate was 78.8 % after 150 days' exposure.

Key words: drip irrigation tape, artificial aging, natural exposure aging, elongation at break
