一、项目简介 第三代全功能农用透光保温膜是一种双层蜂窝式独立气室夹心透光保温膜(以下简称“双层膜”),它是在两层单膜间加一层蜂窝状(含其它立体几何构造)隔膜塑料体制造而成,两层单膜与中间隔膜形成独立气室,气室之间相互独立不连通。双层膜的结构简单,性能独特而优异,属国内外首创产品,是传统农用单层保温膜的理想替代产品。目前双层膜产品已获得国家专利局颁发的专利证书,中国专利号为:ZL 97 2 03629.6。
I. Introduction The third generation full-function agricultural light-transmissive heat-preservation film is a double-layer honeycomb independent air-chamber sandwich light-transmissive heat-preservation film (hereinafter referred to as “double-layer film” Honeycomb (including other three-dimensional geometric structure) diaphragm plastic body made of two single-film and the middle diaphragm to form an independent gas chamber, gas chambers are not independent of each other. The double-layer membrane has the advantages of simple structure, unique performance and excellent performance, and is the first product at home and abroad. It is an ideal substitute for traditional single-layer insulation film for agriculture. Currently double-layer membrane products have been issued by the State Patent Office patent certificate, Chinese patent number: ZL 97203629.6.
