银色反光薄膜是一种新型的多功能农用塑料制品,近年来已应用于农业的许多领域。银色反光薄膜基本上有三种类型:(1)镀铝银膜;(2)三层结构银膜;(3)掺铝型银膜。由于(1)、(2)两种银膜的生产需要特殊加工设备、成本高等原因,只有掺铝型银膜较适合我国的国情。我所研制的聚乙烯掺铝型银膜(以下简称银膜),受到农业应用单位的欢迎。目前该种银膜已通过了技术鉴定,并已生产了10多吨。规格:宽(折径)900毫米;厚0.05—0.15毫米。性能:比重0.90—0.91;反光率≥35％;透光率≤15％。以下就银膜在国内农业上应用的情况作简要介绍:
Silver reflective film is a new multifunctional agricultural plastic products, has been applied in many fields of agriculture in recent years. There are basically three types of silver reflective film: (1) silver-plated silver film; (2) three-layer silver film; (3) aluminum-doped silver film. As (1), (2) two kinds of silver film production requires special processing equipment, high cost reasons, only the aluminum-doped silver film is more suitable for our national conditions. I developed by the aluminum-doped aluminum-doped silver film (hereinafter referred to as silver film), by the application of agricultural units welcome. The current silver film has passed the technical appraisal, and has produced more than 10 tons. Specifications: wide (folding diameter) 900 mm; thickness 0.05-0.15 mm. Performance: The proportion of 0.90-0.91; Reflectivity ≥ 35%; Light transmission ≤ 15%. The following is a brief introduction of the application of silver film in domestic agriculture:
