Detailed Product Description: | Generally unheated greenhouse at night, but the use of solar radiation during the day indoors savings. Therefore, in winter and spring, greenhouse vegetable production, greenhouse night before the insulation covering the slope is very necessary. The most commonly used insulation greenhouse covering materials are mainly grass thatch, paper is, insulation is and nonwovens. A grass thatch is currently the most used straw thatch, followed by rushes, Fu grass, reeds and rushes plus other mountain grass woven grass thatch. Grass thatch is characterized by good insulation effect, drawing convenience, low cost, the actual insulation effect due woven material, grass thatch thickness, different vegetables have different degrees of density differences. Rushes doped reeds, grass thatch grass hill better than straw thatch insulation can be warming 7-10 ℃. Second, the paper is paper is generally used four layers 4-6 layers of new cement bags or kraft paper, sewn into a similar size and grass thatch an insulation material. In the winter season in the grass under thatch covered, reinforced insulation grass thatch lack of capacity, its thermal efficiency can reach about 7 ℃, therefore, paper and grass thatch was used in supporting the insulation effect was significantly enhanced. Three, quilts with cotton, packing cloth, textile waste and cotton (available price is relatively cheap substandard cotton cloth or a short-chien flint from the system. Quilt is characterized by good insulation properties, double-sided waterproof, anti-aging, Low temperature, heat capacity than grass thatch Another feature is the use of long-life, if kept, and can be used 6-7 years. lightweight retractable convenient, but the cost is high, into a larger one. Fourth, nonwoven It is a polyester fiber cloth material, not weaving processes, and the use of thermocompression bonding the fiber-like material made of a fabric according to the length of polyester fibers, can be divided into long fiber nonwoven fabric, staple fibers woven of greenhouses on the insulation cover for long-fiber nonwoven fabric weight per square meter can be divided into a variety of specifications, such as 20 g, 30 g, 40 g, 50 g, the greater the weight per square meter , the insulation, the better. woven with energy-saving insulation, frost frost, reducing greenhouse indoor condensation, cooling and disease prevention, shade dimming effect of increasing production and it's use in vegetable production is relatively extensive. In the greenhouse, supporting the use of plastic film greenhouses, mainly as greenhouses, sheds within the thermal screen. hanging woven thermal screen films should be separated with 30 - 40 cm, can be made of thermal screen activities, opened during the day and night coverage. |
