Tightness. We should keep greenhouses tightness, only tightness reached in order to play the role of insulation, insulation covering material previously used straw thatch, Po seats, etc., although it can play the role of insulation, but the drawback is heavy, volume put a lot of work laborious, after being soaked in the rain and snow, not only increasing the weight, but also make insulation insulation performance degradation is, but the film is the wholesale pollution insulation, easy to reduce the transmission rate. The greenhouse insulation is a lightweight, waterproof, anti-aging, insulation, and other far-infrared reflectance function, long life, good insulation effect, under the same conditions than the grass thatch covering temperature can be increased by 10 degrees for easy storage collection, the product suitable for greenhouse, Greenhouse, eco-restaurant, long-distance trucks, greenhouses and other insulation cover, grass thatch and paper is the best alternative. Because waterproof insulation is required Uncovery day, frequent unwinding and pulling work, resulting in a needle is too large, then the needle is too large have risks? Today, we briefly introduce. Waterproof insulation at the eye of a needle being cold insulation seepage will be, if it rains or snows weather, rain and snow will be very easy to enter into the waterproof insulation is insulation core insulation manufacturers were allowed to insulation core moisture, and reduce its thermal insulation properties, and some of the materials are waterproof insulation material is waterproof, so water entering the insulation core can not be discharged through the eye of a needle. So easy to make long-term use waterproof insulation was lost due to damp insulation properties, affecting the normal growth of the crop. Windproof insulation was _ _ Jiangsu insulation was widely St. agricultural machinery provided by Shouguang Agricultural Machinery Co., St. Canton. Shouguang City, Canton St. Agricultural Machinery Co., Ltd. (www.sdguangsheng.com) strong, credible, Weifang in Shandong agricultural machinery industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the broad St. agricultural machinery and you hand into the brilliant, for a better future!
