我库从一九八五年开始,与甘肃皮塑研究所合作经过多次试验,研制出特种苫盖塑料,试用塑料薄膜代替苇席苫盖露天粮垛.该苫盖塑料人工老化时间超过500小时,是普通塑料时间的8倍。经过几年的试验使用证明该塑料苫盖露天粮垛不影响储粮品质,粮垛卫生、美观,防虫霉,防火防水性能好,便于检查粮情.一个120吨左右的露天垛用苇席苫盖要1350元,而用该种塑料只需 Our library has worked with Gypsum Institute of Leather and Plastic in many experiments since 1985. We have developed a special plastic cover and tried plastic film instead of reed seats to cover the open stack.This plastic cover has an artificial aging time exceeding 500 Hour, eight times the normal plastic time. After several years of tests to prove that the open lid pallets plastic pallets does not affect the quality of grain storage, grain pallets health, beauty, insect repellent, fire and water resistance, easy to check grain conditions. A 120 tons of open piled with reed Xi Cover to 1350 yuan, but with the kind of plastic only
