Abstract

ABSTRACT This study investigated the effects of two different chemical products applied to the soil to on some mechanical properties of greenhouse cover materials produced by CO-EX techology with HALS UV and NIQ UV additives over a period of 12 months. The effects of chemical treatments on the covering materials were investigated in fourteen low tunnels under natural weathering conditions during their useful life. Also, the effects of sulphur products on the pH and electrical conductivity (EC) of the soil were investigated. Initial impact resistance of HALS UV and NIQ UV added PE films were determined as 685.0 and 811.7 g, respectively. Impact resistances of HALS UV and NIQ UV added PE films in bentonite sulphur applications decreased by 48.1% and 33.8%, whereas in elemental sulphur applications decreased by 62.0% and 51.6% after 12 months, respectively. Soil pH was reduced by all sulphur treatments in compared to the initial value.

单质硫和膨润土硫对不同聚乙烯覆盖材料力学性能的影响

摘要本研究在12个月的时间里，研究了两种不同的化学产品对CO-EX技术生产的温室覆盖材料的力学性能的影响，这些材料分别添加了HALS UV和NIQ UV添加剂。在自然风化条件下，对14条低埋隧道进行了覆盖层化学处理对其使用寿命的影响研究。此外，还研究了硫产物对土壤pH和电导率的影响。HALS UV和NIQ UV添加PE膜的初始抗冲击性分别为685.0和811.7 g。12个月后，HALS UV和NIQ UV添加PE膜在膨润土硫应用中的抗冲击性分别下降了48.1%和33.8%，而在单质硫应用中的抗冲击性分别下降了62.0%和51.6%。与初始值相比，所有加硫处理均降低了土壤pH值。

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
