Analysis on the applicable environment and performance of the vegetable greenhouse insulation quilt

The ideal vegetable greenhouse insulation quilt should have the advantages of small heat transfer coefficient, good thermal insulation, moderate weight, easy to roll, good windproof, waterproof, and long service life. It can be used in greenhouse insulation, greenhouse insulation, automobile insulation, door curtains, building insulation, concrete insulation, construction insulation, engineering insulation, road insulation and other purposes. Vegetable greenhouse insulation has a variety of specifications, and can also be processed according to customer requirements. Construction thermal insulation quilts, tarpaulins, thermal insulation curtains can be used for construction thermal insulation, engineering thermal insulation, concrete thermal insulation and anti-freezing and other engineering construction; can also be used for landscaping maintenance, urban greening and anti-freezing, greenhouse thermal insulation, farm thermal insulation, automobile anti-freezing, truck thermal insulation , Goods cold and frost protection, household and supermarket insulation and other purposes. It can be used to process camping tents and protective covers of various machinery and equipment, and can be used to cover open warehouse stacks in stations, docks, seaports and airports. The freight tarpaulins of cars, trains and ships can be used as materials for building temporary sheds and temporary warehouses on various construction sites such as construction sites, power construction sites, etc. It can be used to build temporary granaries and cover various crops in the open air. The vegetable greenhouse insulation is made of high-strength, high-heat insulation, waterproof, anti-freeze, insulation, lining protection and other functional insulation covering materials to ensure the good performance of the product. According to the requirements of different regions, climatic conditions and planting crops, the targeted proportions can be customized, so as to meet the applicable requirements of various regions. The width of the thermal insulation quilt is 2~3 meters. Customers can choose to process the quilt with velcro or buttonholes, so that the entire vegetable greenhouse thermal insulation quilt is connected as a whole, and it is resistant to wind and rolling. With light weight, waterproof, anti-aging, thermal insulation, and other functions, the service life can be as long as 8 years. The greenhouse insulation quilt is at the front end of the back wall of the greenhouse and should be fixed at the center of the top of the wall, so that the top of the wall has a corresponding slope to the north. When the greenhouse insulation quilt covers the bottom of the greenhouse, if there is a large amount of accumulated water on the ground, the accumulated water should be cleaned up to prevent the insulation quilt from being soaked for a long time. The overlap between the two beds should not be less than ten centimeters when using the greenhouse insulation quilt. The lower end of the nylon rope under the quilt is fixed on the horizontal iron rod, and the upper end is fixed on the steel wire. If the curling is wrong during use, it should be adjusted in time to cover all , After the thermal insulation quilt is installed, use the connecting rope to connect the quilt laps into one. Analysis of the applicable environment and performance of the vegetable greenhouse insulation quilt: 1. Heat resistance: The rainproof greenhouse insulation quilt has good heat resistance. When the temperature is below 110 ℃, it will only cause the water on the quilt to evaporate without damaging the fibers. Therefore, the rainproof and thermal insulation quilt has no effect on its quality when used at room temperature, thereby improving the environmental applicability of the rainproof thermal insulation quilt. 2. Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substances, nitrogenous substances and pectin. The quilt has been inspected and practiced in many aspects. 3. Hygroscopicity: The rain-proof thermal insulation quilt has good hygroscopicity. Under normal circumstances, the fiber can absorb moisture into the surrounding atmosphere, and its moisture content is 8-10%. If the humidity of the cotton body increases, the surrounding temperature will increase. If it is higher, the water content in the fiber will all evaporate and dissipate, so that the body can maintain a water balance state. 4. Thermal insulation: The rainproof thermal insulation quilt has good thermal insulation performance, which can keep the plants in the greenhouse at a suitable temperature. Because the weather is dry in winter, it is a dangerous season with high fire incidence, and the vegetable greenhouse insulation quilt is a flammable item, so everyone should pay more attention to its fire prevention and combustion measures. It may make everyone's efforts for a year in vain, so the gains outweigh the losses. Today's vegetable greenhouse insulation is made of plastic products on the outside and cotton on the inside. It is very easy to burn after encountering an open flame, and the fire will spread very quickly after encountering a strong wind. Only by controlling the source of ignition can similar situations be effectively avoided. happened. Smoking is strictly prohibited for people entering and leaving the warehouse, and secondly, they must be instilled with a stable awareness of fire prevention and theft, so that they always remember the importance of fire prevention and stability. Secondly, there are multiple fire extinguishers in the warehouse, which can be put out in time when encountering a small-scale fire. Once again, the staff must ventilate the warehouse regularly. The purpose of ventilation is not to prevent fire, but to keep the vegetable greenhouse insulated from moisture and affect the quality.
