遮阳网是以聚乙烯(或聚丙烯)为原料,加入光屏障剂制成的黑色(或银灰色)的网状织物,它具有遮荫、挡雨、保湿、夜间增温等特点。我们依据遮阳网本身的特点,通过二年多的试验研究,最新提出了用塑料遮阳网代替草帘作保温材料的新方法,且广泛运用于生产中。1 塑料遮阳网夹无纺布的保温性为了探索遮阳网的保温性能,于1991年冬进行了小拱棚覆盖遮阳网加无纺布的保温试验。作保温材料的试验处理有:二层遮阳网加一层无纺布,四层遮阳网加二层无纺布,六层遮阳网加三层无纺布,纯
Shade net is made of polyethylene (or polypropylene) as raw material, adding light barrier made of black (or silver gray) mesh fabric, which has the shade, rain, moisture, night warming and so on. According to the characteristics of the sunshade net itself, through more than two years of experimental research, the latest proposal of using plastic sunshading net instead of grass curtain as a new method for insulation materials is widely used in the production. 1 plastic shade net folder insulation of non-woven In order to explore the thermal insulation properties of the shade net, in the winter of 1991, a small shed covered shade net plus non-woven insulation test. Insulation materials for the test treatment are: two layers of shading plus a layer of non-woven, four shading plus two layers of non-woven, six shading plus three layers of non-woven, pure
