通过试验就环境温度对农膜光学性能、流滴性能、力学性能、沿折缝线开裂等几方面的影响做了分析比较和测试。提出在农膜的设计生产中需考虑到环境温度对薄膜品质的影响,特别是冬夏温差大的企业有必要按环境温度调整农膜的配方及工艺。
The effects of ambient temperature on the optical properties, dripping performance, mechanical properties and cracking along crease lines were analyzed and compared. Proposed in the design and production of agricultural film to be taken into account the impact of ambient temperature on the quality of the film, especially in large temperature difference between winter and summer enterprises need to adjust the formula and process of agricultural film temperature.
