塑料薄膜用于灌溉渠道防渗,是近十几年来新发展的一项技术,新疆农业生产单位已有所应用,但还不普遍。随着塑料工业的迅速发展,这项防渗材料和防渗技术必降得到普遍推广。 一、塑料薄膜防渗的优点 塑料薄膜用于渠道防渗,优点很多: 1.防渗效果好。塑料薄膜整体性强,具有化学惰性,本身完全不透水,如果接缝处理得好,可减少渠道渗漏损失70—96％。
Plastic film is used for seepage control of irrigation channels. It is a newly developed technology in recent ten years. Agricultural production units in Xinjiang have been used but are not yet widespread. With the rapid development of the plastics industry, this impermeable material and anti-seepage technology must be universally promoted. First, the advantages of plastic film impermeable Plastic film for canal seepage, a lot of advantages: 1. Anti-seepage effect is good. Plastic film integrity, chemically inert, completely impermeable per se, if the seam is well handled, can reduce the channel leakage loss of 70-96%.
