Detailed Product Description: | Also known as greenhouses greenhouse is a greenhouse type of north China, the main structure of galvanized steel, is a non-heated greenhouse in the room, only to rely on solar heat to maintain the temperature of the room to meet crop production needs, must have good lighting greenhouse roof, to maximize accept the sun, the heat storage capacity, and strong enough, can effectively reduce the greenhouse heat. Greenhouse insulation covering material is a traditional grass thatch, Po seats, etc, but these materials are heavy, laborious retractable, waterproof performance is also poor, soaked by the rain during the rainy season while the weight increase resulting greenhouse insulation performance, use insulation made of textile waste being produced, with its two-sided waterproof performance, excellent thermal insulation properties, good anti-aging and low temperature resistance, light weight, saving time and effort. Achieved good insulation effect when the foundation excavation according to the local geology flexibility, generally deepened 0.5 m, width 1 m as well, with the Panax dust stirred compaction. Construction data are as follows: a length of 80 m is better, the longest not exceed 150 m, otherwise. Insulation effect is not good. Width of 6-10 m, two hollow brick (standard brick) walls: the middle empty, both sides of 240 mm, the middle filling (or perlite and other insulation materials, wall thickness can be reduced width) to ensure the wall at 700-800 mm, at intervals of 3 m brick wall cut connection. -3.2 M back wall 3 meters high. Lime plaster interior walls, exterior cement mortar smooth. 3 3-3.8 m high ridge, according to the span adjustment, the minimum can not be less than 3 meters. High collapse than the average for the two; 14 to corner before the roof is generally 60-70 degrees. Front roof plane angle = local latitude -16.33 degrees, usually in the 22.4-13.5 degrees. After the roof elevation is generally 40-45 degrees, five greenhouses pitch: high ridge is generally 2.5 times. 6 outdoor cold ditch: the outdoor 0.5m, 0.5 * 0.5 m digging a ditch, filled with straw, slag and other cold outside intrusion prevention, internal temperature leakage. 7 Outer cover: transparent film (PVC 0.1mm PE0.09mm EVA0.08mm) insulation is such grass thatch |
